Bell's inequalities

Bell's inequalities are like a test that scientists use to check if something is weird or not. The scientists are trying to figure out how things work in the world, like how people and objects move, and how they change over time.

So they do an experiment, kind of like a game, where they measure things and look at the results. They use little things called particles that are too small for us to see, but they can measure them using machines.

Bell's inequalities say that if everything is normal, then the particles should behave in a certain way. But sometimes, the particles act weird and don't follow the rules. This means that something strange is happening, and the scientists need to figure out what it is.

Scientists use Bell's inequalities to help them understand how the world works and to discover new things we didn't know before. It's like a puzzle that they are working on, and every time they find a new piece, they get closer to the solution.
