To date, 57 particles have been found, challenging theoretical physicists to come up with a description of reality that includes them all. American physicist Michael Peskin believes that the LHC will be a great help in finding even more particles. “It might turn out to be like the 1950s, when we were discovering many new particles and had no clue about how they fit into a coherent picture.” He adds, “I hope it will turn out like that. This is what makes science fun.”
