Google is paying tribute to Erwin Schrödinger with its homepage doodle today, as it honors the Austrian quantum physicist on what would have been his 126th birthday. The Nobel Prize winner was born on this day in in 1887 in Vienna, where he would also die on January 4th, 1961.

Schrödinger is known for having created the basis of wave mechanics through his work in quantum theory. He formulated what is known as the Schrödinger equation, which shows how the quantum state of a physical system changes with time, among other notable achievements in the field.

He won the Nobel Prize for Physics for the formulation of the equation in 1933.

Schrödinger is also well known for his paradoxical thought experiment, “Schrödinger’s Cat”. The experiment, which was developed in 1935, involves a cat, which could be both alive and dead, depending on something that occurred earlier in time. Here’s a look from IDTIMWYTIM:

Schrödinger wrote numerous works about various fields of physics, including statistical mechanics, thermodynamics, electrodynamics, physics of dielectrics, general relativity, cosmology and color theory. He also wrote about philosophy and theoretical biology.

Several of Google’s recent doodles have been science-oriented, including one earlier this month honoring Maria Mitchell, the first American professional female astronomer and DNA pioneer Rosalind Franklin, so the Schrödinger doodle joins an ever-growing list of science tribute from the technology giant.

Google is showing the Erwin Schrödinger doodle on its homepages around the globe. The Breaking Bad fans out there might be interested to know that according to Google’s Knowledge Graph, people who search for Erwin Schrödinger also search for Werner Heisenberg.
