Particles were coming out of the lithium, hitting the screen, and producing scintillations. They looked like stars suddenly appearing and disappearing.

The discovery that light elements could be disintegrated by artificially accelerated particles gave an additional impetus to development work on the various methods of producing them.

As the size of cyclotrons increases and faster particles are produced, a difficulty arises due to the relativistic increase of mass of the particle.

A linear accelerator has the advantage that no magnet is required and that its cost should not rise much more steeply than with the energy of the particles required.

Buddhas move freely through birth and death, appearing and disappearing at will.

I really like sort of disappearing.
