Erwin Schrödinger is a famous physicist best known for this thought experiment, Schrödinger's Cat. He used the "the cat is both alive and dead until observed" experiment to better explain his equation which says that quantum matter is both simultaneously a wave and a particle until observed. Schrodinger probably never imagined the cat would be as adorable as the one featured on this science mug with pink accents. This kawaii kitty makes this coffee mug both cute and nerdy simultaneously. Makes a great science gift for any science lover you know.
