I was looking through some of my lesson notes and came up with a couple of questions:
1. Why is it impossible to get a quark by itself? (is it just because pair production exists or is it something really obvious that I'm just not getting?)
2. Why can strange particles only be produced in pairs? (the textbook said conservation of strangeness but I don't get how that links)
Thank you so much in advance! Totally struggling with physics right now -_-
