Quantum contextuality

Quantum contextuality refers to the way that particles in the quantum world, like electrons, can behave differently according to the context. Basically, when you have a bunch of particles, they don't all have to behave the same way. Instead, they can act differently depending on how they are arranged and interacted with. To give an example, it's like having three kids together in a room, and one kid might be nice to one kid, mean to another one, and ignore the last one. This is an example of contextuality—the same kid can show different behavior depending on the context. In the same way, particles in the quantum world can change how they behave depending on the context.
