reader, you have no doubt heard about the LHC
. Conceived as the most powerful accelerator in history, the LHC is housed in a 17-mile-long, 12-foot-wide tunnel beneath Switzerland and France.
It needs 96 tons of liquid helium to keep its magnets cool, and, if they ever get it to work right, might be the first accelerator to detect the elusive, mass-imbuing particle known as the Higgs boson.
