Undone – the hymn of Sisyphus for modern times

There are certain moments in life where everything seems meaningless while we take a look at the final fate of all things and nihilism takes over, especially in the times of great unexpected failure. A crystal-clear philosophy of absurdism can come to rescue in such unsettling moments of existential confusion. When such complicated ideas reveal themselves through a simple, soulful yet philosophical song spanning few minutes, the impact is immense. ODESZA & Yellow House’s song called ‘Undone’ from their collaborative album called ‘the flaws in our design’ is one such song which treasures the ideas from the myth of Sisyphus and the philosophy of existentialism, absurdism given by Albert Camus. Absurdism focuses on giving life our meaning through revolt, passion and freedom.

A simple, soulful song pointing towards the philosophy of Absurdism

“Man stands face to face with the irrational. He feels within him his longing for happiness and for reason. The absurd is born of this confrontation between the human need and the unreasonable silence of the world.”

Albert Camus, The Myth of Sisyphus and Other Essays

Some songs have this magic where you instantly get hooked to them, you cannot put it in words but it makes you feel good. You love the feeling this song creates, but don’t know why. Now it’s in your mind on loop and you brain is completely saturated with it.

Now, there comes a moment when you are busy with something and the same song is playing in background like an ambient noise, like a filler and suddenly you have this epiphany, a revelation about what the song really means. Has this happened with you?

I came across a song in 2023 and thought that I have checked out every corner of this song in my mind, but I was wrong. This song was on loop for almost 10 months (believe me on loop means hardcore omnipresent music) and recently I found something revelatory about this song. It was beyond my superficial interpretation of this song (as this is subjective, maybe I should consider myself a dumb fool to not recognize that important side of the song – someone might have found out that thing, that meaning in their early listening of the same song or maybe I am surely hallucinating in the lands of overthinking! – only the creators know!)

The song I am talking about is from the ODESZA and Yellow House’s EP album “The flaws in our design” called “Undone”. (Written by Clayton Joseph Knight / Harrison Gordon Mills / Emile Van Staden, © Foreign Family Collective Publishing, Gmr Foreign Family Collective)

Flaws in our design by ODESZA and Yellow House

Allow me to take you on a mind trip (what it meant for me actually and what it revealed to me recently)

There’s no time to hide from the sun
There’s no time to come undone
That’s easier said than done
Just pick your poison and run

The song starts with certain urgency – “there is no time”.

The song-writer wants you to face the day and don’t give up. The writer understands that it is difficult to start fresh when every hope is lost, the path you were on, the things you were striving for didn’t come to fruition or didn’t go the ways you wanted. The urgency to exist is far more dominating than what great things you lost. So, writer asks us to start again even though is will be painful. Whatever you will be doing, in the end you are going to die, that finiteness of life brings in the urgency to live, to survive. That is why the song-writer says that even though the poison of existence is painful you must do something stick to something because when the time of departure will come you will fill empty that you didn’t appreciate what existence had to offer. You will call your existence worthless. At least sticking to something will give a meaning to the life – your life – whatever it may be but that will be “your” meaningful life in the end.

I’m struggling to find out where I stand
I keep wrestling with God and with man
Tryna forge a little life in-between
A man can only but dream

The writers are trying to show how the person is going through tough times, this person is trapped in a fight between the natural forces and the people around him/ her.

This is about where do we stand in this grand existence. On a personal level if someone comes to attack me or my loved ones, I consider these lives so precious that I would go beyond limits to save them and yet in the grandiose of all this creation our planet is just a speck of dust. Even if the whole earth is engulfed into some giant star, black hole or is crumbled to dust or vaporized due to a man-made nuclear calamity, nothing in the universe is going to change.

So, how do I justify my worth in this grand existence? It’s somewhat philosophical interpretation of given lines in the song but even on societal level it shows a conflict of the mind. This is a struggle to justify the position of a person in this complicated and chaotic society.

This could also be called as an existential angst; one has to fight with the natural forces of creation and the people around them to create a life they desire. There is always this innate resistance to survive, anything small or large could be responsible for the termination of your existence.     

This resistance to survive and create the life we desire gets converted to the existential angst when all our attempts fail, when we lose hope, these are the difficult times of directionless-ness where we try to question our existence. It’s this confusion, this question that “even when we tried all the possible things why didn’t the come to fruition?”

Forging a little life indicates how small is the success rate when one tries to create their own perfect life. A ‘dream-like’ perfect life.

The time’s come to lay it on the line
When meaning seems so hard to find
It all weighs heavy on the mind
It’s easier to leave it behind

Writers are trying to reiterate the urgency through the finiteness of the life. When the right time comes it reveals everything and when you are facing multiple failures, tremendous hardships it leads to breakdown. This breakdown, this hopelessness puts gasoline in the fire of the existential confusion. It feels like there is no way out. The writers feel the same but they advise to leave this weight behind. This is the weight which is actually holding us back in hard times. Acceptance of the failures is the only way to calm down the mind, learn something new. Sometimes it’s not just about failures, its also about the way we wanted our life to be, even after making many attempts if the things are not turning out the way you want, its better to leave that weight behind and move on.   

There’s no time to hide from the sun
There’s no time to come undone
That’s easier said than done
Just pick your poison and run

Again, the same advice, whatever you will struggle at will eventually make you feel hopeless, directionless but you should stick to something hopeful and move on.

Life can’t be won, can’t be tamed
The point of it all goes unnamed
The lost and the gained weigh the same
When returned to dust or to flame

There is no way to justify life in certain definitive way. It’s the grandeur of life and the infinite possibilities it provides which are more than enough to confuse anyone, especially those who have faced big failures or totally lost hope. There are these moments when you feel that you are not living a better life than your peers are living, when you feel like others’ lives are more happening and interesting than yours – this is the moment when you must appreciate that many people ready to die for the life you currently have.

And in the end, nothing will matter, everything will return to dust – to nothingness. Every transaction you had during your existence will be balanced to null, Nada.

I’m struggling to find out where I stand
I keep wrestling with God and with man
Trynna forge a little life in-between
A man can only but dream

Living is a struggle, living with failures is even worse but that doesn’t stop us to create those little lively moments in difficult times because our time here is finite.  We cannot waste this limited thus precious conscious existence on things which are resisting us from living the lives to the fullest.

The time’s come to lay it on the line
When meaning seems so hard to find
It all weighs heavy on the mind
It’s easier to leave it behind

When you receive the clarity of failure and the reasons behind it, it is always better to leave that weight of guilt, confusion, hopelessness behind to begin a new journey.

There’s no time to hide from the sun
There’s no time to come undone
That’s easier said than done
Just pick your poison and run

Show up, keep your head up, do something and stick to it, you are going to die anyways but make sure that when you die you won’t regret even a single thing, look alive and live your life.

Undone and its (deep) philosophical consequences!

You can call the things mentioned hereon as the garbage generated from my overthinking but bear with me, I have a point. This exactly might be the point of the song-writers while creating this song or this is just my brain connecting some random dots to make sense out of nothingness (that is how trickster our existence and the creation is – again according to my overthinking!)

OK, enough, now to the point!

In single simple line it philosophically goes like this and you can stop reading if you don’t like it!?!!

The recent revelation I had with the song Undone by ODESZA & Yellow House is the philosophy of Absurdism by Albert Camus, so the Myth of Sisyphus comes into picture. This song has uncanny resemblance to the philosophical ideas in absurdism.

Myth of Sisyphus

In Greek mythology, Sisyphus was the king of Ephyra who was known to trick death, escape it and even trap it in its own chains. Sisyphus had tricked the Gods many times and gods were running out of the punishments to make a statement. In their one attempt Gods assigned Sisyphus a simple task – to roll a big boulder up the hill. When Sisyphus started rolling the boulder uphill and once it reached the top of the hill the boulder would roll down and again Sisyphus had to roll it uphill. This went on and on and Sisyphus got trapped in this meaningless task. Gods were relieved in the end.

Nihilism and Sisyphus

Albert Camus’s work on the philosophy of the absurd is one importance aspect of how we justify our existence in this seemingly meaningless existence. 

The meaningless task of Sisyphus is an analogous our daily mundane routines – sleep, wake up, go to job, come home, eat, sleep (then wait for weekend!). EAT, SLEEP & REPEAT. But even after this repetition, even after this boring routine when it comes to dying, we are always more scared to die than to live this meaningless, mundane life. I mean in the end it is all about coming from and returning to the dirt, even after that we crave for this conscious but repetitive, painful and “poisonous” existence.  

The lives we live are full of many small and big cycles, these cycles keep on repeating and we keep on following them. Remember the moment when you achieved something really great and in the next immediate moment you felt empty and directionless? Now that this great feat is achieved what lies next? And you become clueless, then you move on to achieving something far bigger and better and the cycle goes till you eventually die. In the end you weren’t even able to take your body with which you realized your conscious existence. What’s the purpose of all this if it is meant to end into dirt again?

Nihilism – nothingness thus rejects all the ideas which justify conscious human existence rather the existence in totality. Nothing really matters because everything starts and ends into the same worthless things. All this knowledge, all this kindness, all those relationships, all those friendships, all that discipline means nothing, there is no sense in following rules, routines, morality doesn’t make any sense, winners or losers – all end in coffins buried underground.

You must understand that these are the exact feelings many of us go through when we face some great challenges, great failures in our lives. The ideas from Nihilism may get associated to such feelings of meaninglessness. One might think that Nihilism is totally negative way for philosophy of existence but that is not the case. Nihilism also talks about non-attachment, non-possession which are the roots of suffering in life as explained in Buddhism. So, it’s not chalk and cheese scenario to be honest. Life may feel meaningless, filled of mundane routines like the task of Sisyphus and in this life, we are struggling to achieve something to realize in the end that we have to leave all that behind – what a cruel joke!

Existentialism, Absurdism and Sisyphus

What Albert Camus presented in his essays of the Myth of Sisyphus was the philosophy of the absurd.

The tendency of Sisyphus to always play tricks with death is exactly who we are. We are always trying to trick death, reject the death in many ways. Sisyphus shown as the king and having all the enjoyments of the life is who we are; everyone of us wants to live life to its fullest. Like Sisyphus, we all are tied to our routines.  

So, the philosophy of absurdism believes that the universe is meaningless and if people will try to find the meaning of the universe, then they will end up in a conflict. Absurdism calls out to the cycles we keep on repeating throughout our existence achieving nothing in the end; what came in, it went out leaving no trace behind.

The key difference between Nihilism and Absurdism is the extent of acknowledgement. Nihilism completely rejects any attribution or meaning to all aspects of life thereby rejecting the worth of life, whereas absurdism is more open ended. Absurdism believes that whatever the creation, the universe is we are not in sync with it to understand it completely. Absurdism thus is humbler and better ready to upgrade its ideology compared to nihilism.

“I don’t know whether this world has a meaning that transcends it. But I know that I cannot know that meaning and that its impossible for me just now to know it”      

Albert Camus, The Myth of Sisyphus and Other Essays

What Camus beautifully did is provide a justification for such “absurd” nature of existence.

This is exactly why the philosophy of absurdism is in sync with the ideas presented in the song Undone.

Absurdism and Undone

Camus in absurdism explains that when people face scenarios of meaninglessness, scenes of existential crisis they reject the very life they possess – thus suicide.

This suicide could be physical or philosophical.

No need to explain physical suicide in detail, the core is that continuous sufferings reduce the perception of the worth of life, what life offers for the sufferings one goes through.

Philosophical suicide is more interesting (!) people kill their own conscience and submit to some ready-made belief system in order to brutally terminate their own existential confusion. (Now you must appreciate what this philosophical suicide is pointing to – the religions spread across he world and the hatred they create is the best example)

Camus says that our urge to live the life (physically and philosophically) is much more overpowering and influential than our whining, crying excuses to reject life. We value our conscious life more than our submission to death, even if it is mundane.

“What is called a reason for living is also an excellent reason for dying.”

Albert Camus, The Myth of Sisyphus and Other Essays

As Camus says, man is condemned to death and the opposite of suicide is to revolt.

Since we cannot evade death, we must entertain death, keep it busy.

So, Albert Camus gave three possibilities of how one could make sense out of all this absurd life – Revolt, Freedom, and Passion.

– Revolt –

We must not accept any ‘final’ or ‘ultimate’ conclusion or calming justification in our unsettling struggles. Because the moment we get a proper justification to our existential angst, we surrender to that way of life (that is how extreme cases of religion work) and the process of learning and curiosity stops there.

The notion of ‘not hiding from the Sun’ in the song thus signify showing up even when the situations are difficult and unsettling. Sun indicating new day (even though being part of the routine) but with new way to look at it.

‘There is no time to come undone’ creates the urgency. Because, when a person is said to be undone – it means that the person has fallen apart, disintegrated, there is no meaningful attribution, purpose to the life they are living. The urgency to live life in spite of seeming meaningless and in spite of ending into death is a call to follow our instinct of living over suicide (philosophical). The absurdism thus focuses the subjective value of life; even though from outside our routines are mundane, only we know what exactly is happening with our lives and that surely is greatly unique; the way we experience our own life and the way other experience it is very special.

That is exactly why you must not waste your time on whining about the problems, losing hope, giving up on something.

The revolt is appreciating the meaninglessness and is also creating space to grow. Even when in final evaluation when we discover that the life is truly meaningless that should not stop us from giving it our own meaning.

That meaning could be anything, that is why ‘picking “your” poison and run’ becomes extremely powerful in the song and it is scattered throughout the song.

– Passion –

Talking about poison, absurdism talks about Passion.    

Passion calls for living life full of rich and diverse experiences. Again, just because nihilism reveals the meaningless view of life and creation, it should not stop us from appreciating what the life and creation provide us. Just because you know that you will die ultimately that does not stop you from breathing and waking up in the morning hoping that you will live another day.

Passion could be anything, that is why the songwriters figuratively attributed is as a poison. Whatever makes you feel free, liberated is your poison (bear in mind that this is philosophical). Do things that make you feel alive (again philosophically), run, sing, dance, write, fight, curse, play, work but look alive. You will appreciate that every thing you do, every passion you follow, every poison you consume have their own consequences, the moment you face these consequences of your acts – your life will have meaning. That is why this figurative poison in this song is very important.

“Creating is living doubly. The groping, anxious quest of a Proust, his meticulous collecting of flowers, of wallpapers, and of anxieties, signifies nothing else.”

Albert Camus, The Myth of Sisyphus and Other Essays

– Freedom –

Third possibility is the freedom. We are absolutely free to think and behave as we decide. The perspective of life being free is more optimistic take on nihilism. If the creation means nothing that it is exactly what we call it! We can call it whatever we want, that is what freedom is. When you think that you are free, you do whatever you want and at that very instance you will realize that even freedom has constraints.

But, as the creation is infinitely meaningless it is open to up-gradation and rebooting. A truth which holds the capacity to upgrade itself is the real ultimate truth I would say; and in the same sense the freedom which knows its boundaries truly knows the real freedom and hence is the real, pure freedom.

“Thinking is learning all over again how to see, directing one’s consciousness, making of every image a privileged place.”

Albert Camus, The Myth of Sisyphus and Other Essays

(Mathematically Godel’s incompleteness theorem, Spiritually Miyamoto Musashi’s the book of Void talk this exact freedom).

“I know simply that the sky will last longer than I.”

Albert Camus, The Myth of Sisyphus and Other Essays

‘The struggle with Gods and men to create a dreamy life in between’ is the expression where I associate this song with the Myth of Sisyphus – his actions were exactly like some Greek demigod who challenged both humans and Gods.

‘The heavy weight of meaninglessness in the moment of reckoning’ expressed in the song point towards the that nihilistic and hopeless situations in the struggles of our life. Its better to not cling to such nihilistic thought. Passion explained in absurdism thus becomes the savior in such hard times.

‘The wildness of life’ in the song thus shows the ability of our freedom to upgrade itself in the ocean of infinite possibilities.  

“The struggle itself towards the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.”

Albert Camus, The Myth of Sisyphus and Other Essays

Listen to this song again with these thoughts of absurdism in the back of your mind, I am sure you will appreciate the song and its creators more. (‘The flaws in our design’ is a well justified name to this album and each song carries its own philosophy. Also pardon my over-explanation in certain places but you get the point (I hope))

Answering the questions on existence of “the existence”

Attempts to solve the mystery behind creation and existence is one the futile pursuits of humanity. Viktor Frankl’s Logotherapy tries to establish the what, why and how of humanity’s existence.

Part 1 – Viktor Frankl’s Logotherapy for Humanity

The existential question and unsatisfactory answers to it

Almost every one of us have stumbled upon the question about their existence in this big world full of people and things – at least once. “Why am I doing this?”, “What am I doing with my life?” – while listening to that boring lecture/ meeting. “Why does life not make any sense?”, “What should I do now that I have no options left?”, “Why should I help others, when nobody’s helping me?”, “If we are nothing but a speck of dust in this whole universe, then what is the purpose of our creation?”, “Why in first place universe was created and why we exist in this chaotic universe?”, “What is the purpose of creation?”, “Why does bad things always happen with good people only?”, “Why couldn’t I achieve something great even when I am putting more efforts than others?”

Questions like these and their many more extreme versions are one significant part of our life where we are always questioning our existence in this universe. The answers to such questions are also very poetic rather philosophical in a way. “You exist in this world to love”, “You exist in this world to suffer”, “You exist in this universe because someone (especially the God) wants you to experience the beauty of his creation!”, “You exist to establish the Truth and Justice in the society”. Some answers are really practical (but believe me more true) like “You exist because your parents had sex that night”, “You exist because who else would bring drinks from the fridge for me!”, “You exist because someone has to pay the bills”. Some are technical answers like – “You exist because of the consequences of the existence where some ape evolved in order to survive the extremities of changes in nature”, “You are just an accident in this never-ending path of an entropy increasing universe which started from nothing and will end into nothing.”

But, out of all such versions of questions and their answers we never get one satisfactory argument as to understand the real justification behind our existence. One thing is pretty sure about the answers to such existential questions that is –

“There is no absolute version-ed answer to the existential question”.

The human existence is more than just the body. The entity creating the awareness of this physical body, the entity which enables this existence through awareness – “the psyche” is one important part of our existence. Also, understanding who we are can make a successful attempt to signify our existence in the universe. That is where and why psychology provides some answers to existential questions.

What makes any human being “the human being”?

In psychology, there are two very famous schools of thought. The first one was established by Sigmund Freud who posed the important concept of “id, ego and super-ego”. In very simple words, human beings are “driven by pleasure”. As they are a part of evolution, their primitive part of the brain – “id” always seeks for something pleasurable in order to continue, remain and sustain in this evolution. The super-ego is the later cultivated part of the brain where human beings are made more cultural by the conditioning from their parents, guardians. And the ego is the current version of the mind which acts under the influences of id and super-ego.

Alfred Adler later introduced the second school of psychology where he considers man as a social being. Again, in single line what Adlerian psychology says is that, all the actions, decisions, behaviors of a human are driven by the society around him where the biggest motivation is to be strong and powerful in the hierarchy of the society. Adlerian ideas indicate that the humans are “driven by power/superiority”.

Sigmund Freud
Alfred Adler

Now that we have some rough understanding of the two schools of psychology, when we ask the existential question to Freud or Adler the expected answer will be-

“We exist to experience pleasure; we exist to become superior”.

Then the next question is “So what is the difference between animals and humans?” where these two schools fail to justify their answer.

Logotherapy – the satisfactory answer

Viktor Frankl – a holocaust survivor and an Austrian psychiatrist/neurologist experienced the extreme ends of human sufferings and human behavior in Nazi concentration camps like Auschwitz, where he observed and personally experienced the limitations of traditional schools of psychology. His experienced presented in his world-famous book “Man’s Search for Meaning” creates an unimaginable picture of suffering, cruelty, hope, survival which is an epitome of what it means to be a human.

Viktor, in the concentrations camps realized that some people lost that “emotional aspect” of their personality after undergoing so much cruelty and suffering – literally becoming animals; some held on to their core emotions and hoped for survival and survived successfully after all the sufferings – both mental and physical. Some people – even after becoming aware of their death, embraced it with dignity (that too under very inhumane environment).

The important thing to understand is that there was no “drive for pleasure” or “drive for superiority” which made the survivors survive through the concentration camp. (You will find moments in Frankl’s life in concentration camp where only getting a small piece of bread was a luxury. Becoming the leader – “capo” of the prisoner group was the only possible superior position in such camps, one should read the experiences of Frankl to understand what it meant to be a “Capo”. Leader – but finally a prisoner in the end.)

The gist of the whole is that there was no chance for achieving pleasure or power in any ways and still people survived through this camp; many people embraced death without any regret, fear. The main thing that made them endure all these sufferings and mental/ physical hostility was the hope. After surviving through the concentration camp Viktor Frankl made all the efforts to establish the third most important school of psychology called “Logotherapy” which is one important part of Humanitarian Psychology. “Humanitarian” in the sense that human psyche is not just a result of some actions and reactions or influences. It is an independent entity in itself rather than a mere result of interactions, influence of things. Human psyche is not a machine where pressing a key will generate some result/ reaction, it is more than just a machine.

Viktor Frankl coined the word Logotherapy from the Greek word Logos which indicates “meaning”. Logotherapy says that human beings have will for meaning. This meaning drives their course of psyche and ultimately their life.

We will try to touch the fundamental ideas explained by Viktor Frankl in his book “Man’s Search for Meaning” to understand what lies behind the existence of humanity. Interesting thing is that Logotherapy has some plausible explanations to those grand philosophical problems and even those tiny yet peculiar real-life problems.   

Nihilism and Noö-dynamics

One of the biggest things that Logotherapy has achieved is to explain the nihilism. When a person doesn’t find a satisfactory answer for the existential questions (the questions in the earlier part of the discussion) he assumes the world around him as a chaotic one, meaningless one. Nihilism exactly means that life is meaningless. Viktor Frankl solved the problem of nihilism by establishing how one becomes nihilistic. It is the “existential frustration” originated from the mind of the person which sometimes is unable to grasp the big picture thereby rendering the life and the existence itself as an entity making zero sense – meaningless. This frustration later on takes the shape of an illness. Remember that no external entity has created this illness; it is the result of the inability of our own mind to solve the “meaning”, the “purpose” of its being. Frankl calls this as Noögenic illness.

Many people yet loyal to their professions, jobs still are not satisfied with what they are doing. Many people doing the bare minimum to survive their weekdays only to crash into their weekends and getting further sad that it passed in a blink of a moment (the famous “Sunday neurosis”) are the people who are frustrated with what they are doing without actually realizing its purpose. They are just passing through the things, events, interactions due to this frustration of not understanding their existence – thus becoming a nihilist. Some will argue that there are other limitations like social, financial, physical which bind the person to this existential frustration; but there are examples where people came out of some really extraordinary situations and made something great out of those limitations too. What they had was the awareness of their existence, they had found the meaning, purpose of their being, their existence.

Frankl takes support of Frederich Nietzsche’s statement here –

“He who has a ‘why’ to live for can bear almost any ‘how’”

Frederich Nietzsche

One interesting and genius note Frankl made here is the nature of one’s life. An ideal life especially ideal mental health is not a state of an equilibrium rather it is state of constant tension between what one has already achieved and what one has to achieve yet. That is how we evolve and that is also what gives sense to existence as it itself is an epitome of evolution.

“If architects want to strengthen a decrepit arch, they increase the load which is laid upon it, for thereby the parts are joined more firmly together. ”

Viktor Frankl

Significance of determinism and freedom in human life

Now take one completely opposite case of a human being where he is not limited by anything. He is free to do anything and everything – the omnipotent. Will that make him really happy? Will that solve the existential problem? The answer is obviously “No”. When presented with all the possibilities the first thing that will happen to that person is that he will get completely overwhelmed with the expanse and counts of the possibilities and will end up in doing nothing. Some will try to do everything and still will be confused for what they are actually doing with everything as the possibilities are endless. After some time, there will be two categories. The first one will be bored and overwhelmed because they are confused with what to do with everything and anything presented to them and second one will be bored and confused because they are doing everything and anything presented to them.

Thus, Viktor Frankl through his Logotherapy argued that even though freedom is important aspect of human life – it is not the complete truth. The earlier schools of psychology (Freudian and Adlerian) were based on the “mechanisms” present in our lives. When pleasure will be presented the person will react to achieve that, when strength and survival will be presented the person will kill to achieve that superiority. But that is not what always happen; history has examples where people starved themselves for something which would seem meaningless, worthless for another people. People gave their lives for someone who was not even worthy replacement for their sacrifices. The logotherapy actually highlights that humans always have the power to choose their next step, the next best step even in the worse possible case. This breaks the deterministic model of human psyche. Frankl explains that you can predict the behavior of a group as it has its limitations, but it will be always difficult to predict the behavior of single person based on any psychological analysis of theory. (It’s like quantum mechanical theory of psychology!)

Frankl further argued that even when the freedom to choose the actions is realized it eventually will lead to “existential vacuum” thereby posing freedom as rather negative part of human psyche. Freedom to do everything will eventually end in meaninglessness and existential crisis unless it is not supported by responsibility.

With great power…

To explain why it is almost impossible to predict behavior of single human being/ a single human psyche Frankl gave an example of a doctor called Dr. J who was exactly the definition of “the Satan” – “The Mass murderer of Steinhof” (the large mental hospital in Vienna). Frankl explains that when the Nazis initiated their euthanasia program, Dr. J with all power granted to him made sure that every psychotic individual goes to the gas chamber. When the war ended and when he was caught by Russians Frankl assumed that he might have escaped cunningly from Russians prison. Later on Frankl found out that Dr. J was diagnosed with cancer of urinary bladder and died in the Russian prison. In his last days people remembered him as the best comrade, the best person. The person with highest moral standards even the best friend.”

What made Dr. J to completely change his behavior his ideals?

Only upon the realization of the finiteness – the limitedness of his life, Dr. J understood what he could have actually created out of the power and authority he had. And hence Viktor Frankl highlights the importance of responsibility with freedom in human psyche.  Dr. J realized the purpose of his life only when he realized the finiteness of his life that made him the real free person.

In Viktor Frankl’s own words-

“Freedom is in danger of degenerating into mere arbitrariness unless it is lived in terms of responsibleness. That is why I recommend that the Statue of Liberty on the east coast be supplemented by a Statue of responsibility on the West coast ”

Viktor Frankl

We already have the legacy of Stan Lee in similar words:

Logotherapy is not just an answer to the question of “why we as a human beings exist?”, “what actually drives us?”, “What is the essence of freedom in human psyche?”. Logotherapy in itself makes successful attempts to make sense of the all the chaos happening around us. The best and most important aspect of Logotherapy is that it considers human beings as a “self-driven entity” instead of the “external-driven” entity. Man is more than the things around him. Human psyche may get influenced by the “dynamics” around him but that not what completely defines what being human is. A human can always choose the best even in his worst condition.

Viktor Frankl also made successful attempts to answer the question “Why Logos – the meaning/ the purpose is needed?”, “What it means to be a human being?”, “How one can realize his own being?”.

Logotherapy itself is a vast subject of which I am not an expert, but it definitely solved some unsolved existential doubts I had. We will see how and why Logotherapy might actually lead us to more fulfilled life in the next part. We will also see how Logotherapy can provide answers to modern problems in the Part 2 of this blog post.

Ever since that damn apple fell off frw3om the tree on Newton’s head the world of science has exploded and expanded faster than maybe the Universe in which we are continuously questioning the nature of our existence, the nature of reality. Although if one really tries to understand how Newton worked out his ideas on the laws of motion, law of gravity, the calculus, they will know that it surely wasn’t the apple that did all the trick. (Given that “apples” have already contributed to change the course of the humanity in different ways)

Classical Mechanics

Sir Isaac Newton
The discovery of Gravity was not a coincidence

What made Newton’s work great is the predictability, structured-ness of the theories he developed. Newton described gravity as the force of attraction between each and every object in the universe. Higher the masses, closer the objects stronger will be the gravity. These theories make predictions which can be tested and then checked to be right or wrong. And for a long time, they were true. Then there came a time – the time. The time of Albert Einstein, where some people say that he proved Newton wrong. I will say Einstein found more generalized form for Newton’s theory of gravity. The ideas of Newton’s theory of gravity are a chunk of the bigger picture of Einstein’s theory of relativity. The theory of relativity considers the gravity not a force but rather curvature of the fabric of space-time. The mass of the object causes the space-time to curve around it hence causing the nearby objects to fall towards it. It’s like a trampoline where a heavy object is curving the elastic sheet around it wherein if other smaller objects are brought in this elastic sheet, they will be eventually pushed into the heavier objects. Newton thought of gravity as an attraction- a pull, whereas Einstein’s gravity pushes. Like Newton, the Einstein’s theory of general relativity makes predictions which can be tested by doing experiments and are proved to be right. Newton’s gravity could not predict the motion of planet Mercury around the Sun due to its limitations. Einstein’s theory of relativity predicted it accurately. Thereby proving it’s superiority.

Albert Einstein
Gravity is the bending of the fabric of Space-Time

The most important thing about Einstein’s theory of relativity is that it created the awareness of the fourth dimension and made it accessible to humanity in some indirect ways. Although, multiple dimensions are possible in abstract mathematics, but they were never accessible to humanity before the establishment of the theory of relativity. Einstein’s theory of relativity is still standing strong and predicting some of the wonders only universe can manifest.

But you know what, Einstein’s theory of relativity is not the generalized theory of our understanding of the universe. Einstein’s theory of relativity though fits for heavenly bodies, even to the grain of sand but it cannot explain the behavior of the subatomic particles making the atoms of the same grain of the sand. There are still some missing pieces in our understanding of the universe. Meaning that Einstein’s theory of relativity is applicable some special case of the reality we exist.    

Rise of Quantum Mechanics and the EPR Paper

Einstein’s attempt to formulate the theory of everything sets the Quantum mechanics in motion. The basic idea is that Newton’s and Einstein’s approaches were top-down approaches to understand the nature whereas the approaches of quantum mechanics are bottom up where the discussion starts from the subatomic particles and the fields responsible for the generation of the fundamental forces (Electromagnetic force, Strong force, Weak force) in nature. One must understand that gravity is still not explained by quantum mechanics. Which is what in a way was the point of concern for Einstein. The theory of relativity breaks at subatomic levels.

This is the part where the EPR paradox comes in picture.         

In order to understand the comments in the EPR Paper, one needs to understand some basic ideas in quantum mechanics.

The model of an atom has evolved greatly over time which also showcases how we improved our understanding of the universe.

John Dalton thought that matter on many divisions will end up in its smallest indivisible part called atom. Which established different elements will have their own characteristic atoms. This idea helped to establish the weight of an atom of each element. Combination of elements would give weight of the molecule made from that specific combination of atoms. With this idea one can exactly tell the molecular weight of product formed by the chemical reaction of two reactants.

J J Thomson in his experiments on Cathode Ray tube (exactly similar technology used in our old heavy box TVs) found out that if a high voltage is applied between two metal electrodes in a vacuum there is formation of a ray which gets attracted to the positively charged terminal thereby showing the negatively charged particles in this ray “The Cathode Ray”. Stronger the magnetic field stronger the cathode ray will deflect. And based on the relationship between the strength of magnetic field and the extent of deflection ray, Thomson found out that the weight of the particles in the Cathode Ray is very small compared to the weight the atoms. In this way the Dalton’s atomic model was revised to Plum Pudding. Where the electrons are scattered throughout the positively charged environment (Literally like the plum pieces randomly scattered in the pudding)

On further experimentation, Rutherford found out that there is vastly bigger space between the positively charged nucleus and the negatively charged electrons. This was a sort of weird plum pudding. The atom’s plum pudding has all the dough at center which positively charged and is the heaviest part of the atom. The plum pieces i.e., electrons are actually floating around this nucleus which are negatively charged. This devised the planetary model of an atom.

From here on now the real fun begins,

If the electrons are floating around the nucleus, how do they always remain in contact with their own nucleus. What makes them remain “attached” to their nucleus? If they are remaining attached to their own nucleus and are floating around it, after some time the tired light weight negative electron should get attracted towards the strong and dense positive nucleus, thereby becoming unstable. And this doesn’t happen in reality, otherwise nothing would exist from such atom as it will not hold itself longer. Technically, an accelerated electrically charged particle emits electromagnetic energy thereby losing its energy – getting “tired” and eventually falling into the nucleus. 

The Quantum Leap

Niels Bohr further sophisticated the model of Rutherford by assigning circular highways to the electrons around the nucleus. Each highway/freeway (autobahn!) has its speed limit which here in atomic model is the energy level. The difference between energy level of each highway is “quantized”. Meaning that there is no middle lane between each highway, no lane cutting/ lane crossing and no overtaking. The energy gap between each highway i.e., “orbit” is fixed. The change in highway is only possible when the electron gains or losses this fixed “quantized energy”. This jump of electron from on orbit to other coined the term the “Quantum Leap”.

Bohr’s idea was usable for simple atoms like hydrogen but it could not explain the behavior of heavier atoms and hence there was still something missing in the model of atom.

The Wave Particle Duality

Erwin Schrödinger formulated that the electrons don’t actually have discrete highways around the nucleus. Electrons are the particles that behave like a wave around the nucleus. This idea was inspired from the Louis de Broglie’s hypothesis that the subatomic particles like electron actually are the waves around the nucleus. Meaning that you cannot pinpoint the electron around the nucleus. The electron will be anywhere in the space around the nucleus, but it follows certain schedule/ timetable which is the famous Schrödinger Wave Equation.

The schedule of electron is always tightly packed. Electron is not that person who confirms his arrival to a party by immediately saying Yes or No. An electron is that friend in your group who will always has his plans and will ditch you at the last moment. To meet such type of an “electronic friend” i.e., the electron itself you have to study its behavior, its routine which is its waveform. The waveform will give you an idea where your electron hangs out the most. Such hangout places where you have largest chance of finding your electron are the “clouds of high probability” called the orbitals.     

This is where the real problems start to happen. You thought you knew everything about your dear “electronic friend”. The whole foundations of quantum mechanics are based on wave particle duality of subatomic particles.

Spin of an electron

Spin of an electron is actually term used to signify the angular momentum of an electron. Please note that spin of electron does establish that an electron is exactly a ball or a top which is spinning around the nucleus. Rather, spin only represents that there is some measurable angular momentum for an electron.  

Quantum measurements are never “Gentle”

The first and most important idea in quantum mechanics is that on subatomic levels the measurements disturb the state they are trying to measure.

The Heisenberg’s Uncertainty principle tells that if you go for the measurement of the spin of an electron the interaction between your measuring equipment and the electron will change its location. Same thing will happen when you go for the measurement of the position of an electron. The interaction between the equipment measuring the position will change the angular momentum of the electron.

Means, the effects we are trying to measure at such subatomic levels are so interaction sensitive that mere the interaction of measurement will disturb the state of the subatomic particle. Thus, you can either measure the momentum of an electron or position of an electron at a time.

The famous American physicist Leonard Susskind’s own words say,

“You can learn nothing about a quantum system without changing something else”

The quantum measurements are so interaction sensitive that they will change the state of the subatomic particle by merely interacting with the measuring equipment.

It’s like the measuring rotations of a ball in the air where you are physically flying with the ball with tachometer in hand in contact with the ball’s surface. The frictional interaction between tachometer and ball will either change the position or the rotation. Hence, you will only know about either the spin of ball or the position of the ball correctly at once. (I agree that it is one exhausting way to perform such measurements, but it serves the purpose here!)

Interaction during quantum measurements will change the state of the quantum particles

Einstein’s problem with the probabilistic nature of quantum mechanics

The wave nature of electron, the so called “fault” to measure the exact conditions of the subatomic particles all at once, the probabilistic nature of the quantum mechanics puzzled Einstein. Please note that the ideas discussed in quantum mechanics are not just some wild thoughts, these are legitimate mathematical proofs which are conceptually established in place. Einstein despised the idea of entanglement, which was not consistent with the reality he had already developed.

The entanglement- the bizarre child of an innocent mother

One bizarre concept born from an innocent concept is entanglement. As far as nature’s fundamental laws go- for creation of anything, something has to be invested in first place. This is called “conservation”. Law of conservation of energy says that the net energy of a system remains same, remains conserved always, it will change its forms but will always remain same in total. Conservation of mass says that one mass can change to other mass with totally different properties but the net mass of the system will always remain the same. Law of conservation of momentum says that if two objects of different momentum come in contact – collide, the total momentum before collision will be equal to the total momentum after collision.

In the same sense, angular momentum is also conserved in the natural phenomena.

So, now consider that two particles are generated from a particle with certain spin. In order to conserve the angular momentum of the system, the two particles will have exactly opposite spin of each other. This nullifying spin with the spin of the object they are created from will give the net constant spin to the system, thereby conserving the angular momentum of the system.

For any system the momentum is conserved

This type of connection between the new two particles from a system is called as the entanglement in quantum mechanics. (This may be, is the exact cinematic love that transcends all the barriers, all the dimensions in your favorite SCI-FI movies and fantasy movies!)   

God does not play dice

In quantum mechanics, when one tries to measure the state of a subatomic particle, the act of measurement gives a state of that particle, but this act of measurement for getting the information about that particle also fixes the state of another particle entangled with it.

Meaning that if you separate the two entangled particles at a distance and measure the spin of one particle then spin of another particle gets fixed at the moment of measurement. The question is that, how does the other particle get the information of the first particle being measured and its state? Einstein called this idea as “spooky action at a distance”.  

The EPR Paper

Einstein was so sure that there is something lacking in the theory of quantum mechanics that he published his idea about the incompleteness of quantum mechanics today famously known as the EPR Paper. Albert Einstein with Boris Podolsky and Nathan Rosen published the paper to explain why theory of quantum mechanics was still incomplete.

The abstract of this paper itself is intriguing:

“The EPR Paper”

Einstein debates that the reality is bound with all variables perfectly known. Hence, for a theory to be complete and to perfectly explain the reality there has to be one variable for each behavior. Hence, according to Einstein, as the quantum theory is completely based on wave function thereby becoming probabilistic (because wave function only gives the probability of measuring the information of the electron and does not pinpoint it) it is not giving the certain, definite, sure answers to the questions thrown at it. In simple words, if you ask a quantum physicist to pinpoint the electron around a nucleus, she/he won’t pinpoint the electron, instead they will tell that in this area there are high chances that you will find electron. As if, the quantum physicists have not studied the system completely, there is some unknown behavior that they haven’t identified yet which will complete the whole theory. Knowing this unknown variable will remove the tolerances in the theory, will remove the probabilistic nature of the theory.

Hence, Einstein puts the argument in two pieces:

First one attacks the lack of awareness of the all the variables in the quantum theory

The second one attacks on the reality, reality implying that the condition of having a definite state.

In short, either we don’t know completely about what is happening in quantum world or the quantum world does not have a real state.

Where the determinism and theory of relativity breaks

You have to understand the implications of the ideas put forth by Einstein and his colleagues in this paper. Einstein debated that the entangled particles when getting entangled secretly decide the state they are going to be. Hence, when one measures the information of the entangled particles, they seem to have been decided already. As if they have conspired about their states and our quantum theory is lacking to explain this conspiracy. The idea of fixing this state already established the concept of determinism. That every behavior in nature is already decided, it is only our lack of knowledge about nature which actually surprised us about the outcomes we experienced. If we have complete model of nature’s behavior we will not be surprised by the outcome, rather we will predict the outcome in advance. This was the heart of Einstein’s debate.   

One more reason for Einstein’s debate on incompleteness of quantum mechanics was his own theory of relativity. According to Einstein’s theory of relativity, nothing in the universe can travel faster than the speed of light. The clever trick quantum mechanics holds it that even after being separated at larger distance where the light will take significant time to travel from one particle to its entangled counterpart the information of the first particle being measured is instantaneously transferred to the another entangled one. If this is happening instantaneously, then the information of one particle being measured has to travel faster than light to the another entangled one. This was also one point of concern for Einstein.

The concept of locality becomes important here. According to the principle of locality, only the immediate surrounding can affect the state of an object thereby limiting the speed information lesser than the speed of light. But, in quantum mechanics the information transfer is instantaneous irrespective of the distance, meaning that the state of one object even after not being in immediate surrounding is affecting the state of its entangled counterpart. (Park this idea of “locality” for one interesting concept called Quantum Cryptography). This meant that quantum effects if are true then they are non-local. Which established the concept of “non-locality” – challenging and exposing the limits of Einstein’s theory of Relativity. That is why Einstein always argued about the incompleteness of Quantum Mechanics. There were some practical explanations to believe so.

The understanding of Einstein about the incompleteness of quantum mechanics was not just a random philosophical pursuit or some complicated thinking done in the air which was incomprehensible for comparatively dumb people of the times. His idea of reality was influenced by the famous mathematician of his time called Jon von Neumann who was obsessed with structuredness of the fundamental theories. Rather he was the one who defined the standards of a good fundamental theory.

Einstein was unsettled with the idea of the probabilistic nature of the quantum mechanics.

This is the only reason which got Einstein into formulating “The Theory of Everything”. A theory which will combine the gravity from his theory of relativity to the theory of generation of fundamental forces of nature from quantum mechanics (if proven right in his time). Even in his last moments of his life, Einstein was working on “The Theory of Everything”. Today String theory and Loop Quantum Gravity are two strongest contenders for theory of everything. Humanity’s most brilliant minds are working on these theories. The problem is that these theories are completely abstract, conceptual to date and still in incubation mode to design a measurable experiment to check and validate the predictions.

The Nobel Prize in Physics for year 2022 is actually awarded to the contributions made for the real- life experimentation done to prove the completeness of the Quantum Mechanics and its implementation in real world.       

The Nobel Pursuit- Bell’s Inequality

The EPR paper went in hibernation for years but, this actually became a reality in near future. The paper attracted the attention of one of the physicists at CERN called John Stewart Bell. Bell formulated a mathematical argument to explain the idea of hidden local variable in system. If this mathematical argument is proved to be right then this would also prove that Einstein was right all the time.

The Bell’s Paper where he established the inequality due to hidden variable

The beauty of Bell’s inequality is that that it gathers the intangible ideas and inspirations from EPR paper and probabilistic nature of quantum mechanics, wave function into a one definite, measurable and quantifiable equation. The equation given by Bell was testable in real world so that some concrete conclusions could be drawn about the completeness of quantum mechanics.

Bell developed a mathematical expression which was based on the assumption that the quantum mechanics has to be “Locally Real”. Where, Local means that the phenomena in quantum mechanics are not faster than the speed of light as explained and proven by theory of relativity; Real means that quantum mechanics is actually deterministic meaning that every measurement done in quantum mechanical system will give an exact answer, a definite value, a surety, it is only our lack of understanding of some hidden variables which cause the quantum mechanics to not be real.

Once the hidden variable/s in the quantum mechanics are identified, then theory will become consistent with the Classical Mechanics.

Smart thing about Bell’s equation is that it used the ideas of probability to show that quantum mechanics is not probabilistic.

Here is simplification of the idea explained by Bell:

We will set up an experiment where we will measure the spin of two entangled particles. You have to understand that in quantum mechanics the act of measurement itself changes the state of the quantum particle. So, when you are measuring the spin of a particle in say Z-direction, after measurement it spin value will no longer be the same as the measured value.

Now what we will do is that we will measure Z-direction component of the spin of one particle in Lab 1 and X-directional component of the spin of the another one which is entangled with the previous particle in Lab 2. Please note that the distance can be as large as possible on the condition that both labs receive undisturbed, un-interacted entangled quantum particles. The measurements will be exactly simultaneous.

So, the possible measurements we will get from the experiments where we only measure two variables are as follows:

The set of measurements when there are only two variables will be:

Here, M1, M2, M3, M4 are the measurements taken. Thus, for set of all measurements:

Now, the real game begins. According to EPR paper, if there are additional hidden variable/s in the model of quantum mechanics which we are not considering, the number of possible outcomes from the same experiment will increase. Say, if there is one hidden variable which we had not considered before while devising the Quantum theory called Q1, and now we are measuring this additional variable in the experiment then the number of possible states of entangled particles increase as follows:

When a new hidden variable is present in the system and if we measure that additional measurement as Q the number of possible combinations of measurement will increase. See below:

The set of measurements will be:

So, what will be the probability, the chance of getting Z directional spin positive and X-directional spin positive? i.e., What will be P (Z+, X+)?

Now, if there is one hidden variable and we are measuring that hidden variable then for the person who measures Z and Q the value of P (Z+,Q+) will be:

Similarly, for the person measuring X with hidden variable Q the value of P (X+,Q+) will be:

Now pay attention,

If we combine these three equations to establish the relation between them, the equation will be as follows:

Which is the Bell’s Inequality.

And is true, if we put the exact values,

In simple words, more variables driving the system, more will be the combinations of the measurements and thereby more complex the equation need to be to completely explain the system.

If there is hidden variable in the system, the number of possible combinations of measurements will be more than the system with lesser variables considered in the study. Which in turn will affect the balance of the possibilities of the events.

Now understand where does the quantum mechanics starts playing its tricks.

When we start to put the one-to-one values in this equation, we will realize what probabilistic nature can do. Due to the probabilistic nature of the quantum system, the measurements will not have a discrete value which lies on a straight line, rather it follows a sine wave, and if we substitute the values of the measurements from the sine wave function the inequality actually breaks.

The wave function in quantum mechanics actually tell what value it will have for measurement at certain angle. Which is indicated by the blue line in the graph below. The wave function only tells that what will the possibility that the spin will be +1 or the possibility that the spin will be – 1. The red line indicates that the measurements will be discrete (either up spin (+1) or down spin (-1)).  

Wave function does not give discrete values

For our example, if one makes a measurement of so-called hidden variable between Z- component and X-component i.e., along Q axis lying between 45 degrees from both Z and X axes the outcome will break the equality as follows:

The values for the Bell’s Inequality for quantum mechanical measurements is given by using the sine wave given in the graph above:

Hence, from the Wave Function in Quantum Mechanics:

Hence, for Bell’s Theorem in Quantum Mechanical System the inequality breaks as follows:

Which is not possible, indicating that Bell’s inequality does not hold true for quantum mechanics. Proving mathematically that there is no hidden variable in Quantum Mechanics. Quantum measurements are not discrete and give definite values, rather the measurements can take any value until we are measuring them, we can only give the probability of how the measurement will be.

This was a shock for those who considered reality as a very sophisticated and definite. The wave function of quantum mechanics does not follow the Bell’s Inequality. There was a strong need for devising an experiment to check and confirm what actually is true. But you must appreciate the power of mathematics and the intellectual level of human mind which can give such deep insight about the nature of reality.

John Stewart Bell
You can see that he has written the outcomes by classical way as 2 and by quantum way as 2 multiplied by square root of 2

The CHSH inequality

The first person with Nobel Prize in Physics of 2022 called Jon Clauser devised an actual experiment to check the Bell’s Theorem and to confirm whether there is any hidden variable in quantum mechanics. Jon Clauser, Michael Horne, Abner Shimony, and Richard Holt created the experiment and the CHSH inequality for the experiment from the Bell’s inequality.

The setup for experiment is as follows:

Two experimenter Alice and Bob (two important people in quantum cryptography. We will discuss about them in upcoming part) will receive a quantum particle simultaneously. The particles are entangled. Meaning that if Alice measures the Z-directional spin of her particle the spin will change in that direction so Bob again measuring the Z-directional spin of his particle which is entangled with Alice’s particle will give new and changed spin value in Z-direction thereby making the measurement meaningless.

Bell’s Test

So, what Bob will do is that he will measure the X – directional spin of his particle exactly when Alice measures the Z-directional spin of her particle. As the two particles are entangled with each other, we will know two states of the entangled quantum particles simultaneously (which seems like some type of cheating but is a pure possibility). The CHSH inequality for the system becomes as follows:

For any number of measurements, when spin of Alice’s particle in Z-direction indicates +1 then the Bob’s entangled one will have spin -1 in X-direction and vice versa. So, according the spin measurements, the maximum possible outcome of the equation is 2. When the experiment is repeated multiple times to converge to a fixed value, we get the statistical average of the measurements (remember that the wave function is probabilistic in nature, hence only statistical average of the measurements will yield a definite value for the equation)

Thus, for hidden variable in quantum mechanics,

Where the angular brackets indicate the statistical average of the measurements known as Dirac’s bracket notation.

But, from actual experiments done by John Clauser the CHSH inequality breaks. And the result is:

This proved that quantum mechanics does not follow the local realism as conventional classical mechanics do. Quantum mechanics does not have any hidden variable which are causing its probabilistic nature. Rather the reality is probabilistic instead of deterministic, predefined.

In the experiment done by John Clauser and his colleagues, they measured the polarization of entangled photons in two directions.

There was one loophole in the experiment of John Clauser. The angles of polarizers were preset or fixed before the entangled particles were sent out to observers from the source. This adds additional determinism in the experiment thereby making “Locally Real” to some extent, therefore the observations were to some extent discrete. I simple words, the experiment done by John Clauser and his colleagues proved a special case of for inconsistency of Bell’s inequality in Quantum Mechanics.

What Alain Prospect the second Nobel Laureate for Physics in 2022 did, that he closed this “loophole of locality”. Alain Prospect and his colleagues devised an experiment where it was possible to switch the detector settings after the entangled particles are released from the source. In simple words, Alain Aspect’s experiment increased the randomness of the combinations and the removed deterministic, predefined nature of measurement.     

Quantum Teleportation and Quantum Cryptography

So, now know that the quantum entanglement is real phenomena and not only mathematics but the experiments also follow the principles, it demands the value addition to the society. The third Nobel Laureate for Physics in 2022 – Anton Zeilinger used these principles for transfer of encrypted information.

It is now established that if one particle’s state is measured in a setup at that exact moment the state of the particle entangled with it gets fixed irrespective of the distance. It shows that the information of the first particle being measured is transferred with the speed faster than the speed of the light.

But there is one more catch,   

If we have to check the state of the second entangled particle to understand how the first particle behaved, we need to understand in what orientation of the equipment the first particle was measured. This information of the orientation of the equipment cannot be shared to the other end beyond the speed of light. But there is still use of this information. If only the people at both the ends measuring the entangled particles know the settings, orientation of measuring equipment, then only they can understand what the states of particle are.

If the entangled particles interact with some other particles or are intercepted by some enemy, there states will no longer remain the same. The information of the orientation of the equipment will show that.

Hence, the orientation of the equipment for measuring the state of entangled particles becomes a secret key for two observers- one of them is sender and another one is the receiver.

And this is exactly called as Quantum Cryptography. Quantum Teleportation refers to the transfer of information irrespective of the distances as the entanglement is instantaneous.

This implementation of quantum teleportation was done Anton Zeilinger and his colleagues using photons.

Alice will decide the equipment orientation while measuring the state
Bob will use the information of Alice’s equipment orientation for decryption
The one where someone tried to intercept

The name Alice and Bob- The “Power-couple of Quantum Cryptography” first appeared in a paper. The Alice and Bob characters were invented by Ron Rivest, Adi Shamir, and Leonard Adleman in their 1978 paper “A Method for Obtaining Digital Signatures and Public-key Cryptosystems”.  Instead of using some boring name Machine A and Machine B they used Alice and Bob. (Some say that the secret message is Valentine’s Day Poem). The names became popular in no time and for any experiment in quantum mechanics you need to involve Alice and Bob. (Given that the love they have for each other!)

Philosophical implications of Bell’s inequality

The breaking of Bell’s Inequality shows that the quantum mechanical system has no hidden variables. Please note that the quantum mechanical systems are the most fundamental systems to date for the whole humanity’s understanding of the universe. This implies that even though the fundamental nature our reality is consistently changing, there are ways to completely understand. One can know the complete system without understanding it’s hidden variables.

The breaking of this inequality both theoretically and experimentally proves that the reality is not definite, predefined. This shows that nature is not deterministic. The idea that reality is mere superposition of infinite possibilities and the one of them becomes apparent only when you interact with them measure is really enlightening. The approach of your measuring equipment, the way you approach the things in nature is like the perspective you hold. The things will define their states their nature according to your perspective is such a humbling idea and learning from all these efforts of humanities greatest minds.
