Maya Ballgame, which is a branch of the Mesoamerican Ballgame, is a sporting event that was played throughout the Mesoamerican era by the Maya civilization. The Maya civilization was spread out throughout much of Central America. One of the common links of the Mayan culture of Mexico, Guatemala, Honduras, and Belize is the game played with a rubber ball, about which we have learned from several sources. Maya ballgame was played with big stone courts. The ball court itself was a focal point of Maya cities and symbolized the city's wealth and power.

The Long Range Acoustic Device (LRAD) is an acoustic hailing device and sonic weapon developed by LRAD Corporation to send messages and warning tones over longer distances or at higher volume than normal loudspeakers. LRAD systems are used for long-range communications in a variety of applications including as a means of non-lethal, non-kinetic crowd control.

Perry Orson Crawford, Jr. (August 9, 1917 – December 13, 2006) was an American computer pioneer credited as being the first to fully realize and promote the value of digital, as opposed to analog, computers for real-time applications. This was in 1945 while advising Jay Forrester in developing flight simulators and anti-aircraft fire control devices during World War II, before practical digital computers had been produced. His similar foresight on related issues led to his heading twelve years later the design team for IBM's SABRE project, the ticketing system for American Airlines, the first large-scale commercial application of real-time computer systems, which became the model for on-line transaction processing.

The Long Range Acoustic Device (LRAD) is an acoustic hailing device and sonic weapon developed by LRAD Corporation to send messages and warning tones over longer distances or at higher volume than normal loudspeakers. LRAD systems are used for long-range communications in a variety of applications including as a means of non-lethal, non-kinetic crowd control. According to the manufacturer's specifications, the systems weigh from 15 to 320 pounds (6.8 to 145.1 kg) and can emit sound in a 30–60° beam at 2.5 kHz. The manufacturer also produces systems for public address and mass notification use that broadcast 360°. LRAD systems are used by law enforcement, government and defense agencies, as well as maritime and commercial security companies to broadcast audible notifications and warnings over distance. LRAD systems are also used to deter wildlife from airport runways, wind and solar farms, nuclear power facilities, gas and oil platforms, mining and agricultural operations, and industrial plants.

The Heysel Stadium disaster (German pronunciation: [ˈɦɛizəl]; French pronunciation: ​[ɛizɛl]; Dutch pronunciation: [ˈɦɛizəl]; German: Katastrophe von Heysel; Dutch: Heizeldrama; French: Drame du Heysel; Italian: Tragedia dell'Heysel or Strage dell'Heysel) was a human stampede that occurred on 29 May 1985 when mostly Juventus fans escaping from a breach by Liverpool fans were pressed against a collapsing wall in the Heysel Stadium in Brussels, Belgium, before the start of the 1985 European Cup Final between the Italian and English clubs. 39 people—mostly Italians and Juventus fans—were killed and 600 were injured in the confrontation. Approximately an hour before the Juventus–Liverpool final was due to kick off, Liverpool supporters charged at Juventus fans and breached a fence that was separating them from a "neutral area." The cause of the rampage is disputed: Many accounts attribute blame to the Italian fans for sparking the violence, but this claim is contested by other eye-witnesses and has been criticized for being unsubstantiated. Juventus fans ran back on the terraces and away from the threat into a concrete retaining wall. Fans already standing near the wall were crushed; eventually the wall collapsed, allowing others to escape. Many people climbed over to safety, but many others died or were badly injured. The game was played despite the disaster, with Juventus winning 1–0. The tragedy resulted in all English football clubs being placed under an indefinite ban by UEFA from all European competitions (lifted in 1990–91), with Liverpool being excluded for an additional three years, later reduced to one, and 14 Liverpool fans found guilty of manslaughter and each sentenced to three years' imprisonment. The disaster was later described as "the darkest hour in the history of the UEFA competitions".
