Surely this century could pass as the golden age of physics. With each decade, some discovery or invention--the electron, the cyclotron, the atom bomb--appeared, changing our world forever. But in the rush of developments, it's been easy to forget who discovered what. Let's see, was it Bethe who came up with the maser, or Townes? Or neither one? Did Heisenberg invent the cyclotron, or was that Oppenheimer? Test your knowledge of the people behind the physics by matching their names with their achievements.
