Schrodinger's Cat Paradox


Listen Later

Now let's dive into a thought experiment known as Schrödinger's Cat. This concept comes from the world of quantum mechanics and was proposed by Austrian physicist Erwin Schrödinger in 1935. Although it sounds complicated, I'll do my best to explain it in a simple, understandable way.

Imagine you have a cat inside a completely sealed box. Also in the box, there's a radioactive atom, a Geiger counter (a device that detects radiation), a vial of poison, and a hammer. When the Geiger counter detects the radioactive atom decaying, it will trigger the hammer to smash the vial of poison, which will kill the cat.
Now, according to quantum mechanics, the radioactive atom exists in multiple states at once. In our example, this means the atom is both decayed and not decayed at the same time. However, when we open the box and look inside, we'll see the cat is either dead or alive. This is where the paradox comes in.
As long as the box remains closed, we don't know if the cat is dead or alive. Therefore, some scientists argue that until we observe the cat, it exists in a state of being both dead and alive simultaneously. It's only when we open the box and observe the cat that it becomes either one or the other.
In conclusion, Schrödinger's Cat Paradox is an intriguing concept from the world of quantum mechanics that questions the nature of reality and how observation affects the state of particles. It beautifully demonstrates how complex and fascinating the world of quantum mechanics can be and continues to pose important questions for scientists today.
