In 1968 Shirley Chisholm became the first Black woman elected to the United States Congress. In 1972 she launched a campaign for the Democratic presidential nomination, breaking another political barrier.

A criticality accident is an accidental uncontrolled nuclear fission chain reaction. It is sometimes referred to as a critical excursion, critical power excursion, divergent chain reaction, or simply critical. Any such event involves the unintended accumulation or arrangement of a critical mass of fissile material, for example enriched uranium or plutonium. Criticality accidents can release potentially fatal radiation doses if they occur in an unprotected environment. Under normal circumstances, a critical or supercritical fission reaction (one that is self-sustaining in power or increasing in power) should only occur inside a safely shielded location, such as a reactor core or a suitable test environment. A criticality accident occurs if the same reaction is achieved unintentionally, for example in an unsafe environment or during reactor maintenance. Though dangerous and frequently lethal to humans within the immediate area, the critical mass formed would not be capable of producing a massive nuclear explosion of the type that fission bombs are designed to produce. This is because all the design features needed to make a nuclear warhead cannot arise by chance. In some cases, the heat released by the chain reaction will cause the fissile (and other nearby) materials to expand. In such cases, the chain reaction can either settle into a low power steady state or may even become either temporarily or permanently shut down (subcritical). In the history of atomic power development, at least 60 criticality accidents have occurred, including 22 in process environments, outside nuclear reactor cores or experimental assemblies, and 38 in small experimental reactors and other test assemblies. Although process accidents occurring outside reactors are characterized by large releases of radiation, the releases are localized. Nonetheless, fatal radiation exposures have occurred to persons close to these events, resulting in more than 20 fatalities. In a few reactor and critical experiment assembly accidents, the energy released has caused significant mechanical damage or steam explosions.
Power Stroke, also known as Powerstroke, is a family of diesel engines that were produced by Navistar International from 1994 until 2010, and by Ford Motor Company since 2011. Along with its use in Navistar's medium-duty trucks and in the Ford F-Series (including Ford Super Duty trucks), applications include the Ford E-Series, Ford Excursion, and Ford LCF commercial truck, and South American production of the Ford Ranger. From 1994 until 2010, Power Stroke engines sold by Ford were re-branded versions of Navistar International medium-duty truck engines. Since the 2011 introduction of the 6.7 L Power Stroke V8, Ford has designed and produced its own diesel engines. The Power Stroke engine range has been marketed against large-block V8 (and V10) gasoline engines along with the General Motors Duramax V8 and the Dodge Cummins B-Series inline six.
"2000 Excursion" is a song by American rappers and Cactus Jack Records labelmates Travis Scott, Sheck Wes, and Don Toliver. It was surprise released through Cactus Jack and Epic Records as the second single from JackBoys (the artist name for Cactus Jack) and Scott's collaborative compilation album, JackBoys 2, on July 8, 2025. The three artists wrote the song with producers Vegyn, Cardo, and Johnny Juliano. Containing a sample of the 2010 single "Power" by fellow American rapper and Scott's mentor, Kanye West, its title refers to the heavy-duty full-size SUV Ford Excursion.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
