At Long Last, Physicists Calculate the Proton's Mass

This reminds me of the story set in ~1900, when the gray-beard physicist tells his student not to study physics because all the big questions have been answered, and physics as a science will end in a few years.

They didn't quite do it.

They made a simulation which matches reality pretty well, but they worked backwards: they knew the value they wanted and kept tweaking the simulation till it worked.

That's not quite as exciting as being able to calculate it from first principles.

Heh... Interesting writing style... "Like a troubled teenager, the proton is a mess inside and just about impossible to figure out."

I think I'll go now and learn as much as I can about the strong force. Sounds like something I won't learn about in school much.
