In short it goes like this: "There's a cat in a box... That has, like, a 50/50 chance of living because there's a vial of poison that's also in the box. Regular physics would say that it's one or the other. That the cat is either alive or dead, but quantum physics says that both realities exist simultaneously. It's only when you open the box that they collapse into one single event." This quote is me paraphrasing James Ward Byrkit, writer and director of the movie "Coherence" I've just watched. Although Erwin Schrödinger back in 1935, when he first wrote his famous thought experiment, invented pretty complex radioactive trap for the poor cat inside the box, I think that "vial of poison" and James' full description in the script is one of the best interpretation of the quantum paradox there is. The quantum weirdness is one of the most intriguing areas in science, that is still buzzing our minds for about a century now. I wrote ab...
