How does a particles symmetry effect the way it behaves? Do particles with similar symmetry interact with each other in a special way than 2 particles with different symmetries?

What do you mean by symmetry? Do you mean symmetric vs. antisymmetric wavefunctions, i.e. bosons vs. fermions?

well actually i read it in a book, the symbols used to represent symmetry were S with a subscript of 2 or 3 (i don't know how to do a subscript on iphone).

Symmetry is a term for the conservation laws that constrain physical equations. Two interacting particles will obey the laws of physics. It is the laws that have symmetries. For example energy conservation can be thought of as invariance under time translation. So time translation is part of a group of transformations.

This is all very technical but that is what you probably stumbled on and it defies description in simple terms.

Its tied up with Noethers beautiful theorem:

Its not simple and will require considerable study, but represents probably the most profound revelation of modern physics. It stunned Einstein. We have professors here that when they tell their students they sit in silent awe because of how how deep and profound its startling revelation is.

Thanks

Thanks, but I'm fully aware of that. Trying to express this in B-language defeated me and my post is ... ugh.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
