Muḥammad ibn Mūsā al-Khwārizmī (Persian: Muḥammad Khwārizmī محمد بن موسی خوارزمی‎; c. 780 – c. 850), Arabized as al-Khwarizmi with al- and formerly Latinized as Algorithmi, was a Persian polymath who produced works in mathematics, astronomy, and geography. Around 820 CE he was appointed as the astronomer and head of the library of the House of Wisdom in Baghdad.

Al-Khwarizmi's popularizing treatise on algebra (The Compendious Book on Calculation by Completion and Balancing, c. 813–833 CE) presented the first systematic solution of linear and quadratic equations. One of his principal achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications. Because he was the first to treat algebra as an independent discipline and introduced the methods of "reduction" and "balancing" (the transposition of subtracted terms to the other side of an equation, that is, the cancellation of like terms on opposite sides of the equation), he has been described as the father or founder of algebra. The term algebra itself comes from the title of his book (specifically the word al-jabr meaning "completion" or "rejoining"). His name gave rise to the terms algorism and algorithm. His name is also the origin of (Spanish) guarismo and of (Portuguese) algarismo, both meaning digit.

In the 12th century, Latin translations of his textbook on arithmetic (Algorithmo de Numero Indorum) which codified the various Indian numerals, introduced the decimal positional number system to the Western world. The Compendious Book on Calculation by Completion and Balancing, translated into Latin by Robert of Chester in 1145, was used until the sixteenth century as the principal mathematical text-book of European universities.

In addition to his best-known works, he revised Ptolemy's Geography, listing the longitudes and latitudes of various cities and localities. He further produced a set of astronomical tables and wrote about calendaric works, as well as the astrolabe and the sundial. He also made important contributions to trigonometry, producing accurate sine and cosine tables, and the first table of tangents.

Richard Allensworth Jewell (born Richard White; December 17, 1962 – August 29, 2007) was an American security guard and law enforcement officer who alerted police during the Centennial Olympic Park bombing at the 1996 Summer Olympics in Atlanta, Georgia. For months afterwards he was suspected of planting the bomb, leading to adverse publicity that "came to symbolize the excesses of law enforcement and the news media."

While working as a security guard at the Olympic Park, Jewell discovered a backpack containing three pipe bombs on the park grounds. He alerted law enforcement and helped evacuate the area before the bomb exploded, probably saving many people from injury or death.

Initially hailed by the media as a hero, Jewell was soon considered a suspect by the FBI and local law enforcement based on scientific profiling. Though never charged, he underwent a "trial by media", which took a toll on his personal and professional life. Jewell was cleared as a suspect after 88 days of public scrutiny. Eric Rudolph eventually confessed and pleaded guilty to that bombing and other attacks. The media circus surrounding the investigation, which was leaked to the press, has been widely cited as an example of law enforcement and media excesses.

In recent years, Jewell's heroic legacy has been the subject of popular culture, including the 2019 film Richard Jewell, and the drama anthology series Manhunt.

Thomas Harriot (Oxford, c. 1560 – London, 2 July 1621), also spelled Harriott, Hariot or Heriot, was an English astronomer, mathematician, ethnographer and translator who made advances within the scientific field. Thomas Harriot was recognized for his contributions in astronomy, mathematics, and navigational techniques. Harriot worked closely with John White to create advanced maps for navigation. While Harriot worked extensively on numerous papers on the subjects of astronomy, mathematics, and navigation the amount of work that was actually published was sparse. So sparse that the only publication that has been produced by Harriot was The Briefe and True Report of the New Found Land of Virginia. The premise of the book includes descriptions of English settlements and financial issues in Virginia at the time. He is sometimes credited with the introduction of the potato to the British Isles. Harriot was the first person to make a drawing of the Moon through a telescope, on 26 July 1609, over four months before Galileo Galilei.

After graduating from St Mary Hall, Oxford, Harriot travelled to the Americas, accompanying the 1585 expedition to Roanoke island funded by Sir Walter Raleigh and led by Sir Ralph Lane. Harriot was a vital member of the venture, having learned and translating the Carolina Algonquian language from two Native Americans: Wanchese and Manteo. On his return to England, he worked for the 9th Earl of Northumberland. At the Earl's house, he became a prolific mathematician and astronomer to whom the theory of refraction is attributed.

🔗 Biography

Gregory F. Packer (born December 18, 1963), is a retired American highway maintenance worker from Huntington, New York, best known for frequently being quoted as a "man on the street" in newspapers, magazines and television broadcasts from 1995 to the present. He has been quoted in hundreds of articles and television broadcasts as a member of the public (that is, a "man on the street" rather than a newsmaker or expert). Although he always gives his real name, he has admitted to making things up to get into the paper.

Packer's status as a frequent interviewee is due to a number of factors, including seeking out members of the press and appearing friendly, although mostly it is due to his hobby of attending public appearances of celebrities and other media events and attempting to be first in line on such occasions. This has led to him being dubbed a professional line sitter. It has also led to Packer's other claim to fame: being the first person in the world to buy an iPhone, on June 29, 2007 at Apple Fifth Avenue in New York City, after having camped out for five days in front of the store. (He tried to similarly be the first to buy an iPad in 2010, but was bumped from the first position in line due to not having a reservation.) His efforts to be first in line have also allowed him to meet people including Mariah Carey, Garth Brooks, Dennis Rodman and Ringo Starr, as well as at least four presidents of the United States: Jimmy Carter, Bill Clinton, George W. Bush and (before he became president) Donald Trump.

Isaac Newton (4 January 1643 – 31 March 1727) was considered an insightful and erudite theologian by his Protestant contemporaries. He wrote many works that would now be classified as occult studies, and he wrote religious tracts that dealt with the literal interpretation of the Bible. He kept his heretical beliefs private.

Newton's conception of the physical world provided a model of the natural world that would reinforce stability and harmony in the civic world. Newton saw a monotheistic God as the masterful creator whose existence could not be denied in the face of the grandeur of all creation. Although born into an Anglican family, and a devout but unorthodox Christian, by his thirties Newton held a Christian faith that, had it been made public, would not have been considered orthodox by mainstream Christians. Scholars now consider him a Nontrinitarian Arian.

He may have been influenced by Socinian christology.

🔗 Biography 🔗 Horticulture and Gardening

Axel Erlandson (December 15, 1884 – April 28, 1964) was a Swedish American farmer who shaped trees as a hobby, and opened a horticultural attraction in 1947 advertised as "See the World's Strangest Trees Here," and named "The Tree Circus."

The trees appeared in the column of Robert Ripley's Believe It or Not! twelve times. Erlandson sold his attraction shortly before his death. The trees were moved to Gilroy Gardens in 1985.

🔗 Biography 🔗 AIDS

Robert Rayford (February 3, 1953 – May 15 or 16, 1969), sometimes identified as Robert R. due to his age, was a teenager from Missouri who has been suggested to represent the earliest case of HIV/AIDS in North America based on evidence published in 1988 in which the authors claimed indicated he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported once at a scientific conference in Australia in 1999; however, the data have never been published in a peer-reviewed medical or scientific journal.
