A data breach, also known as data leakage, is "the unauthorized exposure, disclosure, or loss of personal information".

Attackers have a variety of motives, from financial gain to political activism, political repression, and espionage. There are several technical root causes of data breaches, including accidental or intentional disclosure of information by insiders, loss or theft of unencrypted devices, hacking into a system by exploiting software vulnerabilities, and social engineering attacks such as phishing where insiders are tricked into disclosing information. Although prevention efforts by the company holding the data can reduce the risk of data breach, it cannot bring it to zero. (Full article...)

Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed "The Gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. Concerns about whether the complex Fat Man design would work led to a decision to conduct the first nuclear test. The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, possibly inspired by the poetry of John Donne.

The test, both planned and directed by Kenneth Bainbridge, was conducted in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, on what was the Alamogordo Bombing and Gunnery Range (renamed the White Sands Proving Ground just before the test). The only structures originally in the immediate vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. Fears of a fizzle prompted construction of "Jumbo", a steel containment vessel that could contain the plutonium, allowing it to be recovered; but ultimately Jumbo was not used in the test. On May 7, 1945, a rehearsal was conducted, during which 108 short tons (98 t) of high explosive spiked with radioactive isotopes was detonated. (Full article...)

Group photograph of Project Alberta on Tinian

Project Alberta, also known as Project A, was a section of the Manhattan Project which assisted in delivering the first nuclear weapons in the atomic bombing of Hiroshima and Nagasaki during World War II.

Project Alberta was formed in March 1945, and consisted of 51 United States Army, Navy, and civilian personnel, including one British scientist. Its mission was three-fold. It first had to design a bomb shape for delivery by air, then procure and assemble it. It supported the ballistic testing work at Wendover Army Air Field, Utah, conducted by the 216th Army Air Forces Base Unit (Project W-47), and the modification of B-29s to carry the bombs (Project Silverplate). After completion of its development and training missions, Project Alberta was attached to the 509th Composite Group at North Field, Tinian, where it prepared facilities, assembled and loaded the weapons, and participated in their use.

Di 6 in service with Nord-Ostsee-Bahn of Germany

NSB Di 6, later designated ME 26 and DE 2700, is a class of twelve diesel-electric locomotives built by Siemens for the Norwegian State Railways (NSB). The prime mover provides a power output of 2,650 kilowatts (3,550 hp), a starting traction effort of 400 kilonewtons (90,000 lb_f) and a maximum speed of 160 kilometres per hour (99 mph). They have a Co′Co′ wheel arrangement. The bidirectional locomotives were designed for use with both passenger and freight trains.

The units were ordered by NSB in 1992 as replacements for the aging Di 3, and were particularly intended for use on the Nordland Line and to a lesser extent on the Røros Line. Construction was done by Maschinenbau Kiel (MaK) in Kiel, Germany, which was then part of Siemens Schienenfahrzeugtechnik. The class is largely based on the MaK-built DB Class 240, with each unit costing 32 million Norwegian krone (NOK). The first units were delivered in March 1996, one year after schedule, but were plagued with faults. By 1999, the entire order was terminated and the locomotives returned to Germany. They were taken over by locomotive lessor Dispolok and were used by various Germany railway companies. Ownership was taken over by Vossloh in 2003, after which most of the class were leased to German passenger train operator Nord-Ostsee-Bahn. In 2008, three units returned to Norway and are used by Cargolink for freight trains. (Full article...)

Maryland Route 228 (MD 228) is a state highway in the U.S. state of Maryland. Known as Berry Road, the state highway runs 6.88 miles (11.07 km) from MD 210 in Accokeek east to U.S. Route 301 (US 301) and MD 5 Business in Waldorf. MD 228, which is a four-lane divided highway for its entire length, is a major commuter route between southwestern Prince George's County and northern Charles County. In conjunction with MD 210, the state highway serves as an alternative to US 301 and MD 5 as a route to Washington, D.C. from Southern Maryland. MD 228 also serves as part of the connection, again via MD 210, between Waldorf and Indian Head Naval Surface Warfare Center.

MD 228 did not originally connect Waldorf with Accokeek; instead, the state highway headed west from Waldorf and turned south near the Prince George's – Charles county line, following what is now MD 229 to Pomfret. The state highway was built from Pomfret to Berry in the late 1920s. MD 228 was completed between Berry and Waldorf in the mid-1930s. MD 228 was expanded to a divided highway in Charles County and extended into Prince George's County in the mid-1990s. In 2000, the Prince George's County section of the state highway was reconstructed as a divided highway west to the MD 210 intersection, which was rebuilt as the second continuous-flow intersection in the U.S. (Full article...)

Mississippi Highway 53 (MS 53) is a state highway in Mississippi. The highway starts at U.S. Highway 49 (US 49) in Gulfport and travels northwestward to MS 603 in Hancock County. The road then travels north to Poplarville, meeting Interstate 59 (I-59). MS 53 ends at MS 26 and US 11 in southwestern Poplarville. The road that became MS 53 has existed since 1928, and the highway was designated in 1950. The highway was completely paved by 1957, and an interchange was created at I-59 in 1967. (Full article...)

George Washington Carver
Photograph credit: Unknown; restored by Adam Cuerden
George Washington Carver (1860s–1943) was an American agricultural scientist and inventor. Born into slavery in Diamond, Missouri, he was raised by his master Moses Carver after being emancipated, having been separated from his parents as an infant during a kidnapping incident. After college, Carver became a professor at Tuskegee Institute, where he developed techniques to improve soils depleted by repeated plantings of cotton. He wanted poor farmers to grow alternative crops, such as peanuts and sweet potatoes, as a source of their own food and to improve their quality of life. Carver spent years developing and promoting products made from peanuts, although none became commercially successful. Apart from his work to improve the lives of farmers, he was also a leader in promoting environmentalism. Carver received numerous honors for his work, including the NAACP's Spingarn Medal. In an era of very high racial polarization, his fame reached beyond the black community; he was widely recognized and praised in the white community for his many achievements and talents. In 1941, Time magazine dubbed Carver a "black Leonardo".

This picture of Carver was taken around 1910 and is in the collection of the Tuskegee University archives.

An animation showing how to use a vernier caliper, which is a caliper that uses a vernier scale to interpolate linear measurements. Vernier calipers can measure internal and external dimensions using, respectively, the uppermost and lower jaws, and also depths, using the depth probe (located at the right end). In this example, the first two digits (2.4) are decided by the location of the zero of the vernier scale in the centimeter scale, and the last digit (0.07), by the first line of the vernier scale that exactly matches a line of the centimeter scale above.

Mary Jackson (1921–2005) was an African American mathematician and aerospace engineer at the National Advisory Committee for Aeronautics, which was succeeded by NASA in 1958. For most of her career, she worked at Langley Research Center in Hampton, Virginia; starting as a computer at the segregated West Area Computing division, she later took advanced engineering classes and, in 1958, became NASA's first black female engineer.

After 34 years at NASA, Jackson had earned the most senior engineering title available. Realizing that she could not earn further promotions without becoming a supervisor, she accepted a demotion to become a manager of the Federal Women's Program in the NASA Office of Equal Opportunity Programs, as well as of the Affirmative Action Program. In this role, she worked to influence both the hiring and promotion of women in NASA's science, engineering and mathematics careers. She was portrayed by Janelle Monáe as a lead character in the 2016 film Hidden Figures. This picture, taken in 1980, shows Jackson working at NASA Langley.

Continuous casting
Photo: Alchemist-hp
A disc of copper made by continuous casting, the process whereby molten metal is solidified into a "semifinished" state for subsequent rolling in the finishing mills. Continuous casting replaced the creation of ingots using stationary moulds. The process allows lower-cost production of metal sections with better quality, due to the inherently lower costs of continuous, standardised production of a product, as well as providing increased control over the process through automation. After casting, this disc was then etched to achieve its final state.

George Washington Carver
Photo: Arthur Rothstein; Restoration: Lise Broer
A portrait of George Washington Carver, American scientist, botanist, educator and inventor, from 1942. Much of Carver's fame is based on his research into and promotion of alternative crops to cotton, such as peanuts and sweet potatoes. In addition to his work on agricultural extension education for purposes of advocacy of sustainable agriculture and appreciation of plants and nature, Carver's important accomplishments also included improvement of racial relations, mentoring children, poetry, painting, and religion. One of his most important roles was in undermining, through the fame of his achievements and many talents, the widespread stereotype of the time that the black race was intellectually inferior to the white race.
