Quantum mechanics

Quantum mechanics is a way of thinking about very tiny particles, like atoms and electrons. Instead of treating these particles like regular objects that have a certain size and shape, like a beach ball, we think of them as tiny bundles of energy, like tiny balls of light. These particles can move around in all kinds of ways, and when we look at them, they can look different depending on how they are moving. This is because they are so tiny that they behave differently than regular things, like beach balls. This makes it very hard to predict what they will do, so scientists use quantum mechanics to help understand what is going on.
