Breakthrough?

Millions of years ago, there was no such thing as the wheel. The only way to move things was by carrying or dragging. One day, some primitive guys were watching their wives drag a dead mastodon to the food preparation area. It was exhausting work. The guys were getting tired just WATCHING.
Then they noticed some large, smooth, rounded boulders and they had an idea. They could sit on the boulders and watch! This was the first in a series of breakthroughs that ultimately led to television.

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]
