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]

Little Emily was complaining to her mother that her stomach hurt. Her mother replied, “That’s because it's empty. Maybe you should try putting something in it." The next day, the pastor was over at Emily's family's house for lunch. He mentioned having his head hurt, to which Emily immediately replied, "That's because it's empty. Maybe you should try putting something in it."
