Antimatter
- Dirac predicted that in addition to electrons there must be another particle, called the positron (discovered at Caltech by Anderson), that is necessarily related to the electron.
- All the properties of these two particles obey certain rules of correspondence: the energies are equal; the masses are equal; the charges are reversed; but, more important than anything, the two of them, when they come together, can annihilate each other and liberate their entire mass in the form of energy, say γ-rays.
- The positron is an antiparticle to the electron.

The more one seeks to rise into height and light, the more vigorously do ones roots struggle earthward, downward, into the dark, the deep — into evil.
Richard Phillips Feynman (May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.

A Quantum Transformation
It was the positron, the first predicted particle of antimatter. In 1932, Caltech physicist Carl Anderson discovered the particle, and later physicists spotted the annihilation process Dirac had predicted as well.
When matter and antimatter meet, th...
The Original Discovery
Perepelitsa and his colleagues are dubious that a massless photon could pack a powerful enough punch to melt part of a lead nucleus, which contains 82 protons and 126 neutrons. “It would be like throwing a needle into a bowling ball,” he says.
Instead, he thinks that just b...
Dark Matter Of The Universe
Dark Matter is a bizarre, unknown ingredient of the universe, which scientists cannot observe directly, but takes up 80 percent of the mass of the universe.
It is not seen by the naked eye as it does not emit light or energy. There are entire galaxies (like Dragonfly 44) that are made up e...
