That's in large part thanks to the Tevatron, the machine that first reached the energies needed to discover the last quark in the Standard Model. But the Tevatron has come to the end of its run; at 2pm on Friday, it will be shut down for the last time.
"The fundamental principle of science, the definition almost, is this: the
sole test of the validity of any idea is experiment."
