Erwin Schrodinger (1887-1961) was an Austrian-Irish physicist. He contributed what is now called Schrodinger equations in quantum mechanics and for which he won the Nobel Prize in Physics in 1933. He is also known for his thought experiment called the Schrodinger cat thought experiment.
Like his Friend, Albert Einstein, Schrodinger’s fame rests on four papers he published in quick succession.
In the first paper, in 1926, he showed that there is energy eigenvalues for the hydrogen-like atom, proving a derivation of the wave equation for time independent systems.
The second paper solved the quantum harmonic oscillator problem.
The third paper showed the equivalence of his equations and Heisenberg’s.
The fort and final paper showed how to treat problems in which the system changes with time, as in scattering problems.
Schrodinger was interested in Hinduism especially its philosophical aspect, Vedanta, and wrote a book based on it: What is life? In that book he speculated that individual consciousness may be a manifestation of a unitary consciousness that pervades the universe.
Unfortunately, despite his interest in religion and God, Schrodinger had an interesting life style: he lived with several women at a time, and fathered children all over the place.
In his Schrodinger cat experiment he suggests that a life cat in our world might have a counterpart in parallel worlds.
