I keep seeing these things being mentioned called SU(2) and SU(3) symmetry in particle physics literature. However, I don't know what they mean, and googling around just brings up pages of weird looking mathematics that I don't have the time to sift through and learn right now.(adsbygoogle = window.adsbygoogle || []).push({});

Can anyone give me, or direct me to, a brief explanation of these things, or a summary of what their significance is in particle physics?
