Hello everyone. After some time of using the internet for entertainment purposes, I decided it would be good to actually learn from it. I saw Sagan's Cosmos for the first time, and got very hooked up with Particle Physics. I'm trying to understand but I'm having trouble getting the hang of the whole picture. I hope you can give me a hand. I know that atoms are made up of protons neutrons and electrons. electrons are much more abundant and smaller than neutrons and electrons, etc. also, that protons and neutrons are made up of quarks, while electrons are part of another group called leptons, along with neutrinos. confusion begins when i read about antiquarks, mesons, and how all these things "spin" and "decay" and how nuclear forces act on them. I have a hard time imagining how it all fits together. Would someone explain to me how it all works? Wikipedia answered 10 questions but brought 100 more up. If I need to read through other topics I will do so, I'd just like to be pointed in the right direction. Thanks!
