Ironically, Oswald was himself assassinated a few days later by Jack Ruby. Mark David Chapman was a mentally deranged man who shot and killed John Lennon, lead singer of The Beatles.

- 10. The Greek word “deinos” means terrible, powerful, or wonderous. Combine this with the Greek word “sauros,” which means lizard or reptile, and you might get “dinosaur,” which refers to huge creatures that roamed the earth millions of years ago. The term “dinosauria” was coined by English paleontologist Richard Owen in 1842, which was meant to express the idea that dinosaurs were “terrible reptiles” or “fearfully great lizards.” Over the years, “dinosauria” gradually became “dinosaur,” which is the word we use today to describe those giant beasts from the past.
- 11. Most people think of submarines as amazing underwater naval transports, not as a refuge for sexual discrimination in the military; however, most navies prohibited women from serving on submarines, even after they had been permitted to serve on surface warships. The Royal Norwegian Navy became the first navy to allow female crew on its submarines in 1985. The Royal Danish Navy allowed female submariners in 1988. Others followed suit including the Swedish Navy (1989), the Royal Australian Navy (1998), the German Navy (2001) and the Canadian Navy (2002). Women may serve on US submarines this year, but the British Royal Navy still does not permit women to serve on its submarines.

AIDS is one of the most devastating illnesses in human history. It is estimated that there are over two million AIDS related deaths each year in the world. But perhaps the most infamous and devastating outbreak in history was the bubonic plague or Black Death, which is estimated to have killed 75 million people, or one-third of the population of Europe in the 14th century.
