Niklaus Emil Wirth is a Swiss computer scientist. He has designed several programming languages, including Pascal, and pioneered several classic topics in software engineering. In 1984, he won the Turing Award, generally recognized as the highest distinction in computer science, for developing a sequence of innovative computer languages.
1970 (MCMLXX) was a common year starting on Thursday of the Gregorian calendar, the 1970th year of the Common Era (CE) and Anno Domini (AD) designations, the 970th year of the 2nd millennium, the 70th year of the 20th century, and the 1st year of the 1970s decade.
The charm quark, charmed quark or c quark is the third-most massive of all quarks, a type of elementary particle. Charm quarks are found in hadrons, which are subatomic particles made of quarks. The mass of the particle m=1.27 GeV is very doubtful. Examples of hadrons containing charm quarks include the J/ψ meson, D mesons, charmed Sigma baryons, and other charmed particles.

The Weizmann Institute of Science is a public research university in Rehovot, Israel, established in 1934, 14 years before the State of Israel. It differs from other Israeli universities in that it offers postgraduate-only degrees in the natural and exact sciences.
Martinus Justinus Godefriedus "Tini" Veltman was a Dutch theoretical physicist. He shared the 1999 Nobel Prize in physics with his former PhD student Gerardus 't Hooft for their work on particle theory.
The Marcel Benoist Prize, offered by the Marcel Benoist Foundation, is a monetary prize that has been offered annually since 1920 to a scientist of Swiss nationality or residency who has made the most useful scientific discovery. Emphasis is placed on those discoveries affecting human life. Since 1997, candidates in the humanities have also been eligible for the prize.

The
J/ψ
(J/psi) meson is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark. Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as "charmonium" or psions. The
J/ψ
is the most common form of charmonium, due to its spin of 1 and its low rest mass. The
J/ψ
has a rest mass of 3.0969 GeV/c2, just above that of the
η
c, and a mean lifetime of 7.2×10−21 s. This lifetime was about a thousand times longer than expected.
The year 1931 in science and technology involved some significant events, listed below.
Luciano Maiani is a Sammarinese physicist best known for his prediction of the charm quark with Sheldon Glashow and John Iliopoulos.
John (Jean) Iliopoulos is a Greek physicist. He is the first person to present the Standard Model of particle physics in a single report. He is best known for his prediction of the charm quark with Sheldon Glashow and Luciano Maiani. Iliopoulos is also known for demonstrating the cancellation of anomalies in the Standard model. He is further known for the Fayet-Iliopoulos D-term formula, which was introduced in 1974. He is currently an honorary member of Laboratory of theoretical physics of École Normale Supérieure, Paris.
Daniel Alan Spielman has been a professor of applied mathematics and computer science at Yale University since 2006. As of 2018, he is the Sterling Professor of Computer Science at Yale. He is also the Co-Director of the Yale Institute for Network Science, since its founding, and chair of the newly established Department of Statistics and Data Science.
In particle physics, the GIM mechanism is the mechanism through which flavour-changing neutral currents (FCNCs) are suppressed in loop diagrams. It also explains why weak interactions that change strangeness by 2 are suppressed, while those that change strangeness by 1 are allowed, but only in charged current interactions.
