A U.S. soldier recently, not the most recent, was awarded the Medal of Honor because his group was pinned down and he needed to call in help. He had to go out in the open to get a call through and knew he'd get the shit shot out of him. He did it anyway and got killed but I think the rest of his guys received help.
What is it about a particle that makes it have a particular charge? What is charge fundamentally? Are these known things or just stupid questions on my part? It seems to me if two particles can be different (positive or negative) then they must consist of something smaller that makes them that way.
