Erwin Rudolf Josef Alexander Schrödinger (born on August 12, 1887 in Vienna, Austria) was a physicist who conducted groundbreaking work in quantum mechanics, a field which studies how energy and matter behave at very small length scales. In 1926, Schrödinger developed an equation that predicted where an electron would be located in an atom. In 1933, he received a Nobel Prize for this work, along with physicist Paul Dirac.
Schrödinger may be more popularly known for “Schrödinger's Cat,” a thought experiment he devised in 1935 to illustrate problems with a common interpretation of quantum mechanics.
