In the Appalachian Mountains of the eastern United States, balds are mountain summits or crests covered primarily by thick vegetation of native grasses or shrubs occurring in areas where heavy forest growth would be expected.

Balds are found primarily in the Southern Appalachians, where, even at the highest elevations, the climate is too warm to support an alpine zone, areas where trees fail to grow due to short or non-existent growing seasons. The difference between an alpine summit, such as Mount Washington in New Hampshire, and a bald, such as Gregory Bald in the Great Smoky Mountains, is that a lack of trees is normal for the colder climate of the former but abnormal for the warmer climate of the latter. One example of southern balds' abnormality can be found at Roan Mountain, where Roan High Knob (el. 6,285 ft/1,915 m) is coated with a dense stand of spruce-fir forest, whereas an adjacent summit, Round Bald (el. 5,826 ft/1,776 m), is almost entirely devoid of trees. Why some summits are bald and some are not is a mystery, though there are several hypotheses.

Starfish Prime was a July 9, 1962, high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency. It was launched from Johnston Atoll and was the largest nuclear test conducted in outer space and one of five conducted by the US in space.

A Thor rocket carrying a W49 thermonuclear warhead (designed by Los Alamos Scientific Laboratory) and a Mk. 2 reentry vehicle was launched from Johnston Atoll in the Pacific Ocean, about 900 miles (1,450 km) west-southwest of Hawaii. The explosion took place at an altitude of 250 miles (400 km), above a point 19 miles (31 km) southwest of Johnston Atoll. It produced a yield equivalent to 1.4 megatonnes of TNT. The explosion was about 10° above the horizon as seen from Hawaii, at 11 PM Hawaii time.

Between 1886 and 1959, the price of a 6.5-oz glass or bottle of Coca-Cola was set at five cents, or one nickel, and remained fixed with very little local fluctuation. The Coca-Cola Company was able to maintain this price for several reasons, including bottling contracts the company signed in 1899, advertising, vending machine technology, and a relatively low rate of inflation. The fact that the price of the drink was able to remain the same for over seventy years is especially significant considering the events that occurred during that period, including the founding of Pepsi, World War I, Prohibition, changing taxes, a caffeine and caramel shortage, World War II, and the company's desire to raise its prices. Much of the research on this subject comes from "The Real Thing": Nominal Price Rigidity of the Nickel Coke, 1886–1959, a 2004 paper by economists Daniel Levy and Andrew Young.

Leonard v. Pepsico, Inc., 88 F. Supp. 2d 116, (S.D.N.Y. 1999), aff'd 210 F.3d 88 (2d Cir. 2000), more widely known as the Pepsi Points case, is an American contract law case regarding offer and acceptance. The case was brought in the United States District Court for the Southern District of New York in 1999; its judgment was written by Kimba Wood.

In 1996, PepsiCo began a promotional loyalty program, in which customers could earn Pepsi Points; these points could, in turn, be traded for physical items. A television commercial for the loyalty program displayed the commercial's protagonist flying a McDonnell Douglas AV-8B Harrier II vertical take off jet aircraft to school, valued at $37.4 million at the time, which could be redeemed for 7,000,000 Pepsi Points. The plaintiff, John Leonard, discovered a loophole in the promotion, allowing him to purchase Pepsi Points at 10¢ per point. Leonard promptly delivered a check for $700,008.50 to PepsiCo, attempting to purchase the jet. PepsiCo initially refuted Leonard's offer, citing the humorous nature of the offer in the advertisement. Leonard then sued PepsiCo, Inc. in an effort to enforce the offer and acceptance perceived by Leonard to be made in the advertisement. In her judgment, Wood sided with PepsiCo, noting the frivolous and improbable nature of landing a fighter jet in a school zone that was portrayed by the protagonist. PepsiCo would re-release the advertisement, valuing the jet at 700,000,000 Pepsi Points.

Emma Rowena (Caldwell) Gatewood, known as Grandma Gatewood, (October 25, 1887 – June 4, 1973), was an American ultra-light hiking pioneer. After a difficult life as a farm wife, mother of eleven children, and survivor of domestic violence, she became famous as the first solo female thru-hiker of the 2,168-mile (3,489 km) Appalachian Trail (A.T.) in 1955 at the age of 67. She subsequently became the first person (male or female) to hike the A.T. three times, after completing a second thru-hike two years later, followed by a section-hike in 1964. In the meantime, she hiked 2,000 miles (3,200 km) of the Oregon Trail in 1959. In her later years, she continued to travel and hike, and worked on a section of what would become the Buckeye Trail. The media coverage surrounding her feats was credited for generating interest in maintaining the A.T. and in hiking generally. Among many other honors, she was posthumously inducted into the Appalachian Trail Hall of Fame in 2012.

Elixir sulfanilamide was an improperly prepared sulfonamide antibiotic that caused mass poisoning in the United States in 1937. It is believed to have killed more than 100 people. The public outcry caused by this incident and other similar disasters led to the passing of the 1938 Federal Food, Drug, and Cosmetic Act, which significantly increased the Food and Drug Administration's powers to regulate drugs.
