And when the physicists aren't using them, the beams are used for biomedical research, including cancer therapy.

He can choose which one to participate in simply by using the same power of observation that the physicist uses with an electron.

Physicists use theory to predict how time is measured.

Physicists use the word symmetry whenever they find that physical laws remain indifferent to some change.
