Schrodinger's cat

This cute cat may or may not be healthy, we can not know if we close the lid.

A cat in a box can be dead and alive at the same time. You can not know until you look, it can appear both while in box.

The thought experiment is meant to explain the weirdness of quantum mechanics.

The more you know about the cats position the less you know about its speed. Imagine you have a box with a cat inside, but you can't see the cat or what's happening inside the box. Along with the cat, there is a little machine that has a 50-50 chance of releasing a treat or a yucky smell. If the machine releases the treat, the cat will be happy, and if it releases the yucky smell, the cat will be sad.

Now, until you open the box and look inside, you can't be sure whether the cat is happy or sad. So, in a way, it's like the cat is both happy and sad at the same time. Once you open the box and see the cat, you'll know for sure if it's happy or sad.

Schrodinger's cat is a way to explain a strange idea in quantum mechanics called "superposition." It's like how the cat is both happy and sad until you look, but with really tiny things like particles. When we study these tiny particles, we find that they can be in more than one state at the same time until we measure them.

Physics can not tell you if the cat is dead or alive.
