Rather than hijack Vert's thread of "many successes of mankind" -which is not surprising rather empty (you all know I'm jaded on humanity -I was rather inspired by his listing of what I believe is wrong, but interesting, article relating to a perpetual motion machine and the laws of thermodynamics. I study and teach physics, so this is a topic a bit dear to my heart, and hey, without physics we wouldn't have much on this planet (including no video games, what a tragedy that would be)! So I'll start this thread on physics. Yeah, not sure this thread will get much attention, but what the hey. First article,
this is one of the biggest mysteries in physics today -unifying gravity and quantum mechanics. It's similar to what Einstein was working on in the remaining years of his life -grand unified theories.
