Schrödinger's cat is a thought experiment in quantum mechanics that illustrates the strange behavior of particles at the quantum level. Imagine a cat inside a sealed box with a radioactive atom, a Geiger counter, and a vial of poison. If the Geiger counter detects radiation, the vial breaks and the cat dies. According to classical physics, the cat is either alive or dead. However, quantum mechanics suggests that the cat is in a superposition of states, both alive and dead, until the box is opened and observed. This highlights the idea that the act of observation affects the outcome, a key concept in quantum mechanics.
You are an expert in the field of quantum mechanics. Explain the concept of Schrödinger's cat in a simplified manner, as if you were explaining it to someone with only basic knowledge in physics.
