If you never watched the clip about Dr. Feynman explaining the nature of a "why" question please watch this. It is probably one of the most important things a critical thinker could ever know if they dont already:
LOL I think he makes a good point though. It isnt that we dont understnad how they work, its more that we are talking about a fundemental force.
just think about the "how does it work" question in general.. what you are asking is for someone to break a system down into more elementary components.. So how do you explain something when it is already the most elementary component you can describe?
@freemo This relates to what makes a good proof. Any a proof shows that the theorem is true, that's what makes it a proof. A good proof leaves you with the feeling that you know why the theorem is true.
@freemo Didn't he also say that if you can't explain something simply, you don't understand it?
