The Standard Model of particle physics classifies all known particles in nature and the forces through which they interact. ...[O]ur current version came about in the 1970s. This theory is an absolute triumph: it is mathematically elegant and unbelievably precise, yet it fits on the side of a mug.
Over the last century the experiments... have gone from single-room setups led by one person to the largest machines on Earth. The era of "Big Science," which began in the 1950s... now... involve collaborations of over a hundred countries and tens of thousands of scientists. ...[N]o individual country can achieve these feats alone.
The reason we can say today that we know all this stuff, that we think our theoretical models represent reality, is not because we have pretty mathematics but because we have done experiments.
