Antiproton

In 1955, a new atomic subparticle called a negative proton (antiproton) was discovered at U.C. Berkeley. The hunt for antimatter began in earnest in 1932, with the discovery of the positron, a particle with the mass of an electron and a positive charge. However, creating an antiproton would be far more difficult since it needs nearly 2,000 times the energy. In 1955, the most powerful "atom smasher" in the world, the Bevatron built at Berkeley could provide the required energy. Detection was accomplished with a maze of magnets and electronic counters through which only antiprotons could pass. After several hours of bombarding copper with protons accelerated to 6.2 billion electron volts of energy, the scientists counted a total of 60 antiprotons.[Image: The first annihilation star, Faustina, of an antiproton found in film exposed by the Berkeley scientists, 1955]

The birds and the tee's?

A father spoke to his son, "It's time we had a little talk, my son. Soon, you will have urges and feelings you've never had before. Your heart will pound & your hands will sweat. You'll be preoccupied and won't be able to think of anything else."

He added, "But don't worry, it's perfectly normal... it's called golf."
