Google doodle honours scientist Erwin Schrodinger on 126th birthday
Today is Edwin Schrodinger's birthday, and he is being honoured by Google with a doodle representing the dead-and-alive cat experiment, which has become one of his most famous contributions to science
"The cat is both dead and alive."
The statement encapsulates the theory behindErwin Schrdinger thought experiment. Today is the scientist's 126th birthday, and he is being honoured by Google with a doodle representing this experiment, which has become one of his most famous contributions to science.

The doodle shows a living cat emerging from a box, even as a ghostly white cat with crosses for eyes rises out of the other end of the box.It was somewhere around 1935 that Schrodinger, after extensive discussions and correspondence with the Theory of Relativity genius, Albert Einstein, developed his now famous Schrodinger's Cat Theorem. The experiment is explained thusly by Wikipedia:
"a cat, a flask of poison, and aradioactivesource are placed in a sealed box. If... the flask is shattered, releasing the poison that kills the cat. The Copenhagen interpretation of quantum mechanics implies that after a while, the cat issimultaneouslyaliveanddead. Yet, when one looks in the box, one sees the cateitheraliveordead, not both aliveanddead. This poses the question of when exactly quantum superposition ends and reality collapses into one possibility or the other."

Happy Birthday, Schrdinger. Long ago, we did not know Whether or not your cat was dead. Now, I'm pretty sure we do.
