Good morning.
I have a question that I've been wrestling with since a recent
classroom discussion on mass and energy within the context of special
relativity. I hope I'm able to articulate the questions correctly
enough to get a useful answer.
Classically, an object's mass is apparently related to the number of
atoms that make up that object (e.g. a block of aluminum has a certain
number of aluminum atoms in it). The only way to change the object's
mass is to change the number of atoms in the object . . .
