Facts of the Day

Baby Boom
After World War II, many industrialized countries experienced a "baby boom." Four countries in particular - the United States, Canada, Australia, and New Zealand - experienced sustained and substantial rises in fertility from the depressed levels of the prewar period. In the U.S., for example, fertility rose by two-thirds, reaching levels between the 1950s and 1980 not seen since 1910, before World War I. Some even demarcate the Baby Boom period as being January 1, 1946-December 31, 1964 - in which over 77 million births occurred.

Tornado
Tornadoes are violent windstorms that are also called twisters or cyclones. Extremely fast, rotating columns of air descend from cumulonimbus clouds and the winds can either cause explosions within buildings or sweep objects up into its eye. A tornado sounds like a thundering train coming through. Tornadoes occur all over the world except on the two poles and are the most common in the U.S. A tornado over water is called a cyclone. They occur in unstable air, as that caused by a thunderstorm. In the center of a tornado, winds can get to 400 miles per hour (650 km).

Typewriter
In 1867, the American inventor Christopher Latham Sholes read an article in the journal Scientific American describing a new British-invented machine and was inspired to create what became the first practical typewriter. His second model was patented the next year and "wrote" at a speed far faster than a pen. Though the first typewriter was crude and large, it underwent improvements each year and in 1873 Sholes signed a contract with E. Remington and Sons for its manufacture and the machine was soon named a "Remington." It wrote capital letters only; the first shift-key typewriter (Remington 2) appeared on the market in 1878 and could write uppercase and lowercase. There was a serious problem with jamming, so one of Sholes's business associates, James Densmore, suggested splitting up keys for letters commonly used together, thereby creating the slowest keyboard arrangement possible. This arrangement - known as the QWERTY keyboard - is still used in almost all computers today. Mark Twain purchased a Remington and became the first author to submit a typewritten book manuscript.

Custer's Last Stand
The Battle of Little Bighorn, otherwise known as Custer's Last Stand, was fought at the Little Bighorn River in Montana Territory between federal troops led by Lieutenant Colonel George A. Custer and band of combined Indian tribes. Custer and all of his men were killed. The outcome of the battle was so upsetting to Americans that government troops flooded the area, forcing the Indians to surrender.

Korean War
The Korean War started out being between North Korea and South Korea. After World War II, Korea was hurriedly divided for administrative purposes at the 38th parallel. Almost immediately, the Soviets began a short-lived reign of terror in northern Korea that quickly politicized the division by driving thousands of refugees south. An independent South Korea became UN policy in early 1948 and southern communists opposed this, so warfare began in parts of every Korean province below the 38th parallel. The war became international in June 1950 when North Korea, supplied and advised by the Soviets, invaded South Korea. The United Nations, with the United States as the principal participant, joined the war on the side of the South Koreans, and the People's Republic of China came to North Korea's aid. In 1953, Joseph Stalin died, and within weeks the Politburo of the Soviet Communist Party voted that the war in Korea should be ended. After more than a million combat casualties on both sides, the fighting ended in July 1953 with Korea still divided into two hostile states.
