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.

Cecilia Helena Payne-Gaposchkin (née Payne; (1900-05-10)May 10, 1900 – (1979-12-07)December 7, 1979) was a British-born American astronomer and astrophysicist who proposed in her 1925 doctoral thesis that stars were composed primarily of hydrogen and helium. Her groundbreaking conclusion was initially rejected because it contradicted the scientific wisdom of the time, which held that there were no significant elemental differences between the Sun and Earth. Independent observations eventually proved she was actually correct

She developed one of the world's first high-level languages with indirect address in programming, called the Address programming language. Over the period of her academic career, Yushchenko supervised 45 Ph.D students. Further professional achievements include Yushchenko being awarded two USSR State Prizes, The USSR Council of Ministers Prize, The Academician Glushkov Prize, and The Order of Princess Olga. Yushchenko was the first woman in the USSR to become a Doctor of Physical and Mathematical Sciences in programming.

Joseph P. Nacchio (born June 22, 1949 in Brooklyn, New York) is an American executive who was chairman of the board and chief executive officer of Qwest Communications International from 1997 to 2002. Nacchio was convicted of insider trading during his time heading Qwest. He claimed in court, with documentation, that his was the only company to demand legal authority for surreptitious mass surveillance demanded by the NSA which began prior to the 11 September 2001 attacks.

He was convicted of 19 counts of insider trading in Qwest stock on April 19, 2007 – charges his defense team claimed were U.S. government retaliation for his refusal to give customer data to the National Security Agency in February, 2001. This defense was not admissible in court because the U.S. Department of Justice filed an in limine motion, which is often used in national security cases, to exclude information which may reveal state secrets. Information from the Classified Information Procedures Act hearings in Nacchio's case was likewise ruled inadmissible.

On July 27, 2007, he was sentenced to six years in federal prison, and after appeals failed he reported to Federal Correctional Institution, Schuylkill in Schuylkill County, Pennsylvania on April 14, 2009 to serve his sentence. Nacchio finished serving his sentence on September 20, 2013.

Maryam Mirzakhani (Persian: مریم میرزاخانی‎, pronounced [mæɾˈjæm miːɾzɑːxɑːˈniː]; 12 May 1977 – 14 July 2017) was an Iranian mathematician and a professor of mathematics at Stanford University. Her research topics included Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. In 2005, as a result of her research, she was honored in Popular Science's fourth annual "Brilliant 10" in which she was acknowledged as one of the top 10 young minds who have pushed their fields in innovative directions.

On 13 August 2014, Mirzakhani was honored with the Fields Medal, the most prestigious award in mathematics. Thus, she became both the first, and to date, the only woman and the first Iranian to be honored with the award. The award committee cited her work in "the dynamics and geometry of Riemann surfaces and their moduli spaces".

On 14 July 2017, Mirzakhani died of breast cancer at the age of 40.
