Erwin Schrödinger

Birthdate: 12. August 1887
Date of death: 4. January 1961

Erwin Rudolf Josef Alexander Schrödinger , sometimes written as Erwin Schrodinger or Erwin Schroedinger, was a Nobel Prize-winning Austrian physicist who developed a number of fundamental results in the field of quantum theory, which formed the basis of wave mechanics: he formulated the wave equation and revealed the identity of his development of the formalism and matrix mechanics. Schrödinger proposed an original interpretation of the physical meaning of the wave function.

In addition, he was the author of many works in various fields of physics: statistical mechanics and thermodynamics, physics of dielectrics, colour theory, electrodynamics, general relativity, and cosmology, and he made several attempts to construct a unified field theory. In his book What Is Life? Schrödinger addressed the problems of genetics, looking at the phenomenon of life from the point of view of physics. He paid great attention to the philosophical aspects of science, ancient and oriental philosophical concepts, ethics, and religion. He also wrote on philosophy and theoretical biology. He is also known for his "Schrödinger's cat" thought-experiment.

Erwin Schrödinger

„The world is given to me only once, not one existing and one perceived. Subject and object are only one.“

—  Erwin Schrödinger

Mind and Matter (1958)
Context: The world is given to me only once, not one existing and one perceived. Subject and object are only one. The barrier between them cannot be said to have broken down as a result of recent experience in the physical sciences, for this barrier does not exist. <!-- p. 127

„This life of yours which you are living is not merely a piece of this entire existence, but in a certain sense the whole; only this whole is not so constituted that it can be surveyed in one single glance.“

—  Erwin Schrödinger

My View of the World (1961)
Context: This life of yours which you are living is not merely a piece of this entire existence, but in a certain sense the whole; only this whole is not so constituted that it can be surveyed in one single glance. This, as we know, is what the Brahmins express in that sacred, mystic formula which is yet really so simple and so clear; tat tvam asi, this is you. Or, again, in such words as "I am in the east and the west, I am above and below, I am this entire world."

„Our burning question as to the whence and whither — all we can ourselves observe about it is the present environment.“

—  Erwin Schrödinger

Science and Humanism (1951)
Context: I am born into an environment — I know not whence I came nor whither I go nor who I am. This is my situation as yours, every single one of you. The fact that everyone always was in this same situation, and always will be, tells me nothing. Our burning question as to the whence and whither — all we can ourselves observe about it is the present environment. That is why we are eager to find out about it as much as we can. That is science, learning, knowledge; it is the true source of every spiritual endeavour of man. We try to find out as much as we can about the spatial and temporal surroundings of the place in which we find ourselves put by birth…

„Sensations and thoughts do not belong to the "world of energy."“

—  Erwin Schrödinger

Nature and the Greeks (1954)
Context: The observing mind is not a physical system, it cannot interact with any physical system. And it might be better to reserve the term "subject" for the observing mind. … For the subject, if anything, is the thing that senses and thinks. Sensations and thoughts do not belong to the "world of energy."

„Although I think that life may be the result of an accident, I do not think that of consciousness.“

—  Erwin Schrödinger

As quoted in The Observer (11 January 1931); also in Psychic Research (1931), Vol. 25, p. 91
Context: Although I think that life may be the result of an accident, I do not think that of consciousness. Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.

„The observing mind is not a physical system, it cannot interact with any physical system.“

—  Erwin Schrödinger

Nature and the Greeks (1954)
Context: The observing mind is not a physical system, it cannot interact with any physical system. And it might be better to reserve the term "subject" for the observing mind. … For the subject, if anything, is the thing that senses and thinks. Sensations and thoughts do not belong to the "world of energy."

„I am very astonished that the scientific picture of the real world around me is deficient. It gives a lot of factual information, puts all our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us.“

—  Erwin Schrödinger

Nature and the Greeks (1954)
Context: I am very astonished that the scientific picture of the real world around me is deficient. It gives a lot of factual information, puts all our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity. Science sometimes pretends to answer questions in these domains, but the answers are very often so silly that we are not inclined to take them seriously.

„If I say that there cannot be more than one consciousness in the same mind, this seems a blunt tautology — we are quite unable to imagine the contrary…“

—  Erwin Schrödinger

"The Oneness of Mind", as translated in Quantum Questions: Mystical Writings of the World's Great Physicists (1984) edited by Ken Wilber
Context: Consciousness is never experienced in the plural, only in the singular. Not only has none of us ever experienced more than one consciousness, but there is also no trace of circumstantial evidence of this ever happening anywhere in the world. If I say that there cannot be more than one consciousness in the same mind, this seems a blunt tautology — we are quite unable to imagine the contrary...

„In physics we have dealt hitherto only with periodic crystals.“

—  Erwin Schrödinger, book What Is Life?

To a humble physicist's mind, these are very interesting and complicated objects; they constitute one of the most fascinating and complex material structures by which inanimate nature puzzles his wits. Yet, compared with the aperiodic crystal, they are rather plain and dull. The difference in structure is of the same kind as that between an ordinary wallpaper in which the same pattern is repeated again and again in regular periodicity and a masterpiece of embroidery, say a Raphael tapestry, which shows no dull repetition, but an elaborate, coherent, meaningful design traced by the great master.
What Is Life? (1944)

„Thus you can throw yourself flat on the ground, stretched out upon Mother Earth, with certain conviction that you are one with her and she with you … For eternally and always there is only now, one and the same now; the present is the only thing that has no end.“

—  Erwin Schrödinger

"The Mystic Vision" as translated in Quantum Questions: Mystical Writings of the World's Great Physicists (1984) edited by Ken Wilber
Context: It is not possible that this unity of knowledge, feeling and choice which you call your own should have sprung into being from nothingness at a given moment not so long ago; rather this knowledge, feeling, and choice are essentially eternal and unchangeable and numerically one in all men, nay in all sensitive beings. But not in this sense — that you are a part, a piece, of an eternal, infinite being, an aspect or modification of it... For we should then have the same baffling question: which part, which aspect are you? what, objectively, differentiates it from the others? No, but, inconceiveable as it seems to ordinary reason, you — and all other conscious beings as such — are all in all. Hence, this life of yours... is, in a certain sense, the whole... This, as we know, is what the Brahmins express in that sacred, mystic formula... 'Tat tvam asi' — this is you. Or, again, in such words as 'I am in the east and in the west, I am below and above, I am this whole world.'
Thus you can throw yourself flat on the ground, stretched out upon Mother Earth, with certain conviction that you are one with her and she with you … For eternally and always there is only now, one and the same now; the present is the only thing that has no end.

„Nature does not act by purposes.“

—  Erwin Schrödinger

Mind and Matter (1958)
Context: Nature has no reverence towards life. Nature treats life as though it were the most valueless thing in the world.... Nature does not act by purposes.

„In itself, the insight is not new. The earliest records, to my knowledge, date back some 2500 years or more… the recognition ATMAN = BRAHMAN (the personal self equals the omnipresent, all-comprehending eternal self) was in Indian thought considered, far from being blasphemous, to represent the quintessence of deepest insight into the happenings of the world.“

—  Erwin Schrödinger

"The I That Is God" as translated in Quantum Questions: Mystical Writings of the World's Great Physicists (1984) edited by Ken Wilber
Context: In itself, the insight is not new. The earliest records, to my knowledge, date back some 2500 years or more... the recognition ATMAN = BRAHMAN (the personal self equals the omnipresent, all-comprehending eternal self) was in Indian thought considered, far from being blasphemous, to represent the quintessence of deepest insight into the happenings of the world. The striving of all the scholars of Vedanta was after having learnt to pronounce with their lips, really assimilate in their minds this grandest of all thoughts.
Again, the mystics of many centuries, independently, yet in perfect harmony with each other (somewhat like the particles in an ideal gas) have described, each of them, the unique experience of his or her life in terms that can be condensed in the phrase: DEUS FACTUS SUM (I have become God).
To Western ideology, the thought has remained a stranger... in spite of those true lovers who, as they look into each other's eyes, become aware that their thought and their joy are numerically one, not merely similar or identical...

„The multiplicity is only apparent.“

—  Erwin Schrödinger

As quoted in The Eye of Shiva: Eastern Mysticism and Science (1981) by Amaury de Riencourt <!-- p. 7 -->
Context: The multiplicity is only apparent. This is the doctrine of the Upanishads. And not of the Upanishads only. The mystical experience of the union with God regularly leads to this view, unless strong prejudices stand in the way.

„The difference in structure is of the same kind as that between an ordinary wallpaper in which the same pattern is repeated again and again in regular periodicity and a masterpiece of embroidery, say a Raphael tapestry, which shows no dull repetition, but an elaborate, coherent, meaningful design traced by the great master.“

„What is this Self of yours? What was the necessary condition for making the thing conceived this time into you, just you and not someone else?“

—  Erwin Schrödinger

"Seek for the Road" (1925)
Context: For thousands of years men have striven and suffered and begotten and women have brought forth in pain. A hundred years ago, perhaps, another man sat on this spot; like you he gazed with awe and yearning in his heart at the dying light on the glaciers. Like you he was begotten of man and born of woman. He felt pain and brief joy as you do. Was he someone else? Was it not you yourself? What is this Self of yours? What was the necessary condition for making the thing conceived this time into you, just you and not someone else?

„We cannot, however, manage to make do with such old, familiar, and seemingly indispensable terms as "real" or "only possible"; we are never in a position to say what really is or what really happens, but we can only say what will be observed in any concrete individual case.“

—  Erwin Schrödinger

"The Fundamental Idea of Wave Mechanics", Nobel lecture, (12 December 1933)
Context: Conditions are admittedly such that we can always manage to make do in each concrete individual case without the two different aspects leading to different expectations as to the result of certain experiments. We cannot, however, manage to make do with such old, familiar, and seemingly indispensable terms as "real" or "only possible"; we are never in a position to say what really is or what really happens, but we can only say what will be observed in any concrete individual case. Will we have to be permanently satisfied with this...? On principle, yes. On principle, there is nothing new in the postulate that in the end exact science should aim at nothing more than the description of what can really be observed. The question is only whether from now on we shall have to refrain from tying description to a clear hypothesis about the real nature of the world. There are many who wish to pronounce such abdication even today. But I believe that this means making things a little too easy for oneself.

„Nirvana is a state of pure blissful knowledge… It has nothing to do with the individual. The ego or its separation is an illusion.“

—  Erwin Schrödinger

Writings of July 1918, quoted in A Life of Erwin Schrödinger (1994) by Walter Moore
Context: Nirvana is a state of pure blissful knowledge... It has nothing to do with the individual. The ego or its separation is an illusion. Indeed in a certain sense two "I"'s are identical namely when one disregards all special contents — their Karma. The goal of man is to preserve his Karma and to develop it further... when man dies his Karma lives and creates for itself another carrier.

„We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators.“

—  Erwin Schrödinger

Nature and the Greeks (1954)
Context: We do not belong to this material world that science constructs for us. We are not in it; we are outside. We are only spectators. The reason why we believe that we are in it, that we belong to the picture, is that our bodies are in the picture. Our bodies belong to it. Not only my own body, but those of my friends, also of my dog and cat and horse, and of all the other people and animals. And this is my only means of communicating with them.

„This is not mere allegory, but an eternal memory.“

—  Erwin Schrödinger

Writings of July 1918, quoted in A Life of Erwin Schrödinger (1994) by Walter Moore
Context: No self is of itself alone. It has a long chain of intellectual ancestors. The "I" is chained to ancestry by many factors … This is not mere allegory, but an eternal memory.
