The cyclotron is invented.

The cyclotron is invented. The American physicists Ernest O. Lawrence & his student M. Stanley Livingston construct an ingenious device to study atomic nuclei by probing them with energetic sub-atomic particles. Their cyclotron accelerates these particles by repeatedly cycling them through an electric field and produces particles with extremely high energy. The design inspires generations of particle accelerators that examine nuclei and elementary particles.
