Researchers at Lawrence Livermore National Laboratory have generated billions of positrons, forming the highest antimatter densities ever created on earth, by using superintense short laser pulses. In ...

Theoretical physicist Paul Dirac believed the universe is built using advanced mathematics. He saw this order as the work of ...

Images from physicist Carl Anderson’s cloud chamber reveal a positively charged particle with a mass equivalent to the electron: a positron. This antimatter partner of the electron had been ...

THE experiments of Stern show that the magnetic momentum of the proton is greater than it should be if the proton were an elementary particle. Therefore the proton may be considered as consisting of a ...
