Facts About Antimatter Overview

    • Antimatter

      What’s antimatter? It is part of the plot in Dan Brown’s book Angels and Demons — that is what. The author writes an engaging story – it is fiction, of course. But, antimatter itself is very real.The first particle of antimatter ever to be discovered was the positron. In 1932, Carl Anderson found its tracks while investigating cosmic rays. A positron  has the same mass as an electron, generates the same amount of magnetic field, and has the same amount of charge. But its charge is positive, while the electron’s is negative. The two are exact opposites. If a positron and an electron meet, they can annihilate each other, leaving only energy in the form of light (gamma rays) in their wake… Read more »

    • Symmetry

      The symmetry is a butterfly’s wings or the radial symmetry of a flower contributes to its beauty. But why do such symmetries exist at all? Why are there fascinating symmetries not only among ordinary objects such as butterflies and flowers, but at the deeper level of fundamental physical laws? Many physicists have no answer. Eugene Wigner, nobel laureate in physics, has seen first-hand the fundamental symmetries in laws describing subatomic particles and in the mathematics expressing those laws. He was so struck by the role of mathematics in these laws that he actually wrote an article… Read more »
