Schrödinger’s kitty cat

schrodinger's cat wanted dead or alive

For anyone who is not aware of what this poster means, this is a quantum-mechanical based hypothetical proposal suggested by one of the all time great scientists by name of Erwin Schrödinger. According to, as quoted, “Schrödinger said that if you put a cat in a box with a poison that might kill it, at the end of an hour the cat has a 50% chance of being alive, and a 50% chance of being dead. According to quantum mechanics, since we can’t see in the box to know if the cat is alive or dead, the cat is both alive and dead. Of course, we know that this is not possible, nothing can be alive and dead at the same time. This is just what Schrödinger wanted to show.” There is another website, which probably provides a simpler explanation of what Schrödinger was trying to convey. The above specific cat is actually mine, who posed for me on the desk for this poster 🙂
