Adiabatic theorem

Adiabatic theorem is a big word that is used to explain what happens when we change something very slowly. It's like when you're playing with a toy and you move it very slowly, nothing much will change. This is similar to what happens when scientists talk about adiabatic changes.

In science, there are things called quantum systems, which are tiny particles that move around and interact with each other. These particles can have different energy levels, which tell us how much energy they have and what they can do.

The adiabatic theorem says that if we change something about these quantum systems very slowly, then the energy levels of the particles will stay the same. It's like moving the toy slowly – if we change things slowly, nothing big will happen to the particles.

This theorem is really important because it helps scientists understand how to work with these quantum systems and manipulate them in useful ways. It's like learning a new trick with your toy because you understand how it works better. All in all, adiabatic theorem is a fancy term that just means we should make changes slowly, so we don't mess things up!
