Schrodinger s Pivot, or Why CALCULATE() Should Be Your Favorite Function EVER.

In 1935, physicist Erwin Schrodinger wanted to show Albert Einstein how wrong he was. Einstein had recently published a paper that made an astounding claim about the nature of subatomic particles. If those claims were true, said Schrodinger, even "big" everyday stuff, like cats, could also behave in that same outlandish way. Which made Einstein look kinda silly, in Erwin's mind. He proposed the idea of a cat that was both simultaneously alive AND dead, and basically said "See, Albert? Alive AND dead is clearly impossible, so your theory is junk." See here for details.
