David Rolfe Graeber (; February 12, 1961 – September 2, 2020) was an American anthropologist, anarchist activist, and author known for his books Debt: The First 5000 Years (2011), The Utopia of Rules (2015) and Bullshit Jobs: A Theory (2018). He was a professor of anthropology at the London School of Economics.

As an assistant professor and associate professor of anthropology at Yale from 1998 to 2007, Graeber specialized in theories of value and social theory. Yale's decision not to rehire him when he would otherwise have become eligible for tenure sparked an academic controversy. He went on to become, from 2007 to 2013, reader in social anthropology at Goldsmiths, University of London.

His activism includes protests against the 3rd Summit of the Americas in Quebec City in 2001, and at the 2002 World Economic Forum in New York City. Graeber was a leading figure in the Occupy Wall Street movement, and is sometimes credited with having coined the slogan "we are the 99%". He accepted credit for the description "the 99%" but said that others had expanded it into the slogan.

Marie-Sophie Germain (French: [maʁi sɔfi ʒɛʁmɛ̃]; 1 April 1776 – 27 June 1831) was a French mathematician, physicist, and philosopher. Despite initial opposition from her parents and difficulties presented by society, she gained education from books in her father's library, including ones by Leonhard Euler, and from correspondence with famous mathematicians such as Lagrange, Legendre, and Gauss (under the pseudonym of «Monsieur LeBlanc»). One of the pioneers of elasticity theory, she won the grand prize from the Paris Academy of Sciences for her essay on the subject. Her work on Fermat's Last Theorem provided a foundation for mathematicians exploring the subject for hundreds of years after. Because of prejudice against her sex, she was unable to make a career out of mathematics, but she worked independently throughout her life. Before her death, Gauss had recommended that she be awarded an honorary degree, but that never occurred. On 27 June 1831, she died from breast cancer. At the centenary of her life, a street and a girls’ school were named after her. The Academy of Sciences established the Sophie Germain Prize in her honor.

Taqi al-Din Muhammad ibn Ma'ruf ash-Shami al-Asadi (Arabic: تقي الدين محمد بن معروف الشامي‎, Ottoman Turkish: تقي الدين محمد بن معروف الشامي السعدي‎, Turkish: Takiyüddin) (1526-1585) was an Ottoman polymath active in Cairo and Istanbul. He was the author of more than ninety books on a wide variety of subjects, including astronomy, clocks, engineering, mathematics, mechanics, optics and natural philosophy.

In 1574 the Ottoman Sultan Murad III invited Taqī ad-Dīn to build the Constantinople observatory. Using his exceptional knowledge in the mechanical arts, Taqī ad-Dīn constructed instruments like huge armillary and mechanical clocks that he used in his observations of the Great Comet of 1577. He also used European celestial and terrestrial globes that were delivered to Istanbul in gift-exchange.

The major work that resulted from his work in the observatory is titled "The tree of ultimate knowledge [in the end of time or the world] in the Kingdom of the Revolving Spheres: The astronomical tables of the King of Kings [Murād III]" (Sidrat al-muntah al-afkar fi malkūt al-falak al-dawār– al-zij al-Shāhinshāhi). The work was prepared according to the results of the observations carried out in Egypt and Istanbul in order to correct and complete Ulugh Beg's Zij as-Sultani. The first 40 pages of the work deal with calculations, followed by discussions of astronomical clocks, heavenly circles, and information about three eclipses which he observed at Cairo and Istanbul. For corroborating data of other observations of eclipses in other locales like Daud ar-Riyyadi (David the Mathematician), David Ben-Shushan of Salonika.

As a polymath, Taqī al-Dīn wrote numerous books on astronomy, mathematics, mechanics, and theology. His method of finding coordinates of stars were reportedly so precise that he got better measurements than his contemporaries, Tycho Brahe and Nicolas Copernicus. Brahe is also thought to have been aware of al-Dīn's work.

Taqī Ad-Dīn also described a steam turbine with the practical application of rotating a spit in 1551. He worked on and created astronomical clocks for his observatory. Taqī Ad-Dīn also wrote a book on optics, in which he determined the light emitted from objects, proved the Law of Reflection observationally, and worked on refraction.

Yasuke (variously rendered as 弥助 or 弥介, 彌助 or 彌介 in different sources) was a man of African origin who served as a retainer under the Japanese daimyō Oda Nobunaga. In 1579, Yasuke arrived in Japan in the service of Italian Jesuit missionary Alessandro Valignano, Visitor of Missions in the Indies, in India.

Yasuke is thought by some to have been the first African that Nobunaga had ever seen and he was one of the many Africans to have come with the Portuguese to Japan during the Nanban trade. He was also present during the Honnō-ji Incident, the forced suicide of Nobunaga at the hands of his samurai general Akechi Mitsuhide on 21 June 1582.

Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom from 6 February 1952 until her death in 2022. Her reign of 70 years and 214 days was the longest of any British monarch and the second-longest recorded of any monarch of a sovereign country. At the time of her death, Elizabeth was queen of 14 other Commonwealth realms in addition to the UK.

Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth). Her father acceded to the throne in 1936 upon the abdication of his brother, King Edward VIII, making Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince of Greece and Denmark, and their marriage lasted 73 years until his death in April 2021. They had four children together: Charles III; Anne, Princess Royal; Prince Andrew, Duke of York; and Prince Edward, Earl of Wessex.

When her father died in February 1952, Elizabeth—then 25 years old—became queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon (known today as Sri Lanka), as well as Head of the Commonwealth. Elizabeth reigned as a constitutional monarch through major political changes such as the Troubles in Northern Ireland, devolution in the United Kingdom, the decolonisation of Africa, and the United Kingdom's accession to the European Communities and withdrawal from the European Union. The number of her realms varied over time as territories have gained independence and some realms have become republics. Her many historic visits and meetings include state visits to China in 1986, Russia in 1994, the Republic of Ireland in 2011, and visits with five Popes.

Significant events include Elizabeth's coronation in 1953 and the celebrations of her Silver, Golden, Diamond, and Platinum Jubilees in 1977, 2002, 2012, and 2022, respectively. Elizabeth was the longest-lived and longest-reigning British monarch, and the second-longest verifiable reigning sovereign monarch in world history, only behind Louis XIV of France. She faced occasional republican sentiment and media criticism of her family, particularly after the breakdowns of her children's marriages, her annus horribilis in 1992, and the death of her former daughter-in-law Diana, Princess of Wales, in 1997. However, support for the monarchy in the United Kingdom remained consistently high, as did her personal popularity. Elizabeth died on 8 September 2022 at Balmoral Castle, Aberdeenshire. She was succeeded by her eldest son, Charles III.

Jerry Eugene Pournelle (; August 7, 1933 – September 8, 2017) was an American polymath: scientist in the area of operations research and human factors research, science fiction writer, essayist, journalist, and one of the first bloggers. In the 1960s and early 1970s, he worked in the aerospace industry, but eventually focused on his writing career. In an obituary in gizmodo, he is described as "a tireless ambassador for the future."

Pournelle is particularly known for writing hard science fiction, and received multiple awards for his writing. In addition to his solo writing, he wrote several novels with collaborators, most notably Larry Niven. Pournelle served a term as President of the Science Fiction and Fantasy Writers of America.

Pournelle's journalism focused primarily on the computer industry, astronomy, and space exploration. From the 1970s until the early 1990s, he contributed to the computer magazine Byte, writing from the viewpoint of an intelligent user, with the oft-cited credo, “We do this stuff so you won’t have to.” He created one of the first blogs, entitled "Chaos Manor", which included commentary about politics, computer technology, space technology, and science fiction.

Pournelle was also known for his paleoconservative political views, which were sometimes expressed in his fiction. He was one of the founders of the Citizens' Advisory Council on National Space Policy, which developed some of the Reagan Administration's space initiatives, including the earliest versions of what would become the Strategic Defense Initiative.
