Di Maio. *Metropolis–Hastings algorithm. The algorithm was named after Nicholas Metropolis, who was the director of the Theoretical Division of Los Alamos National Laboratory at the time of writing the paper ''Equation of State Calculations by Fast Computing Machines''. However, Metropolis did not contribute to that study in any way, as confirmed by various Metropolis–Hastings algorithm#History, sources. The research problem was proposed by Augusta H. Teller and solved by Marshall N. Rosenbluth and Arianna W. Rosenbluth. Furthermore, according to Roy Glauber and Emilio Segrè, the original algorithm was invented by Enrico Fermi and reinvented by Stan Ulam. *Moore's Law

*Newton's laws of motion, Newton's first and second laws of mechanics were known and proposed in separate ways by Galileo, Robert Hooke, Hooke and Christiaan Huygens, Huygens before Isaac Newton, Newton did in his ''Philosophiæ Naturalis Principia Mathematica''. Newton owns the discovery of only the third one. *Norman's law, proposed by Donald Norman, is a general restatement of Stigler's Law, "No saying or pronouncement is named after its originator." This law was named for Norman as an example of Stigler's Law – which was, itself, not named after its originator. *Norton's theorem was published in November 1926 by Hans Ferdinand Mayer and independently discovered by Edward Lawry Norton who presented it in an internal Bell Labs technical report, dated November 1926. *Nyquist–Shannon sampling theorem. The name Nyquist–Shannon sampling theorem honours Harry Nyquist and Claude Shannon, but the theorem was also previously discovered by E. T. Whittaker (published in 1915) and Shannon cited Whittaker's paper in his work. (from Wikipedia)

Maraldi a century earlier. *Prim's algorithm, developed in 1930 by the Czech mathematician Vojtěch Jarník and independently rediscovered by Prim in 1957. *Prinzmetal angina, also known as variant angina, referring to angina (chest pain) caused by vasospasm of the coronary arteries.

*Zipf's law states that given some text corpus, corpus of natural language utterances, the frequency of any word is inversely proportional to its rank in the frequency table. The law is named after George Kingsley Zipf, an early twentieth century American linguist. Zipf popularized Zipf's law and sought to explain it, though he did not claim to have originated it. Jean-Baptiste Estoup was the first person to note this regularity in word frequencies.
