Erwin Rudolf Josef Alexander Schrödinger (12 August 1887 – 4 January 1961), was an 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 (stationary and time-dependent Schrödinger 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 and in subsequent years repeatedly criticized the conventional Copenhagen interpretation of quantum mechanics (using e.g. the paradox of Schrödinger's cat). In addition, he is the author of many works in various fields of physics: statistical mechanics and thermodynamics, physics of dielectrics, color 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.

"In one respect, however, he is not a romantic: he does not idealize the person of the beloved, his highest praise is to consider her his equal. "When you feel your own equal in the body of a beautiful woman, just as ready to forget the world for you as you for her - oh my good Lord - who can describe what happiness then. You can live it, now and again - you cannot speak of it." Of course, he does speak of it, and almost always with religious imagery. Yet at this time he also wrote, "By the way, I never realized that to be nonbelieving, to be an atheist, was a thing to be proud of. It went without saying as it were." And in another place at about this same time: "Our creed is indeed a queer creed. You others, Christians (and similar people), consider our ethics much inferior, indeed abominable. There is that little difference. We adhere to ours in practice, you don't." Whatever problems they may have had in their love affair, the pangs of conscience were not among them. Sheila was as much an unbeliever as Erwin, but in a less complex, more realistic way. She was never entirely convinced by his vedantic theology."

He even lost a marriage proposal to his love, Felicie Krauss, not only due to his social status but his lack of religious affiliation. He was known as a freethinker who did not believe in god. But interestingly Schrodinger had a deep connection to Hinduism, Buddhism, and Eastern philosophy in general. Erwin studied numerous books on Eastern thought as well as the Hindu scriptures. He was enthralled with Vedanta thought and connected ideas of oneness and unity of mind with his research on quantum physics, specifically wave mechanics."

"He rejected traditional religious beliefs (Jewish, Christian, and Islamic) not on the basis of any reasoned argument, nor even with an expression of emotional antipathy, for he loved to use religious expressions and metaphors, but simply by saying that they are naive."
