The positron or antielectron is the particle with an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron. It is the antiparticle ( antimatter counterpart) of the electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the ...

Marsha P. Johnson (August 24, 1945 – July 6, 1992) was an American gay liberation [6] [7] activist and self-identified drag queen. [ 8 ] [ 9 ] Known as an outspoken advocate for gay rights , Johnson was one of the prominent figures in the Stonewall uprising of 1969.
Electron–positron annihilation occurs when an electron (. e−. ) and a positron (. e+. , the electron's antiparticle) collide. At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of energetic photons : e−. +.
Positron emission, beta plus decay, or β+ decay is a subtype of radioactive decay called beta decay, in which a proton inside a radionuclide nucleus is converted into a neutron while releasing a positron and an electron neutrino ( νe ). [ 1] Positron emission is mediated by the weak force.
One-electron universe. The one-electron universe postulate, proposed by theoretical physicist John Wheeler in a telephone call to Richard Feynman in the spring of 1940, is the hypothesis that all electrons and positrons are actually manifestations of a single entity moving backwards and forwards in time. According to Feynman:
