Reference excerpt

William Joseph Marciano (born October 11, 1947) is an American theoretical physicist, specializing in elementary particle physics.

Education and career Marciano graduated with a B.S. and an M.S. in physics at New York University. There he received in 1974 his doctorate with Alberto Sirlin as doctoral advisor. Marciano worked from 1974 to 1980 at Rockefeller University, where he started as a research associate and was then promoted to assistant professor. From 1980 to 1981 he was an associate professor at Northwestern University. At Brookhaven National Laboratory (BNL) he was in 1978 a research collaborator in 1978 and in 1981 joined the physics department and was granted tenure. At BNL he was promoted on 1986 to senior physicist and from 1987 to 1998 was the leader of the physics department's High-Energy Theory Group. He is currently at BNL a senior physicist and since 1990 has also been an adjunct professor at Yale University. He has served as an associate editor for Physical Review Letters, Physical Review D, Reviews of Modern Physics, and the Journal of High Energy Physics.

His research interests span many aspects of elementary particle physics including: Precision Electroweak Calculations, Grand Unified Theories, Neutrino Physics, Rare Decays and CP Violation. With Heinz Pagels he wrote a highly-cited review article on quantum chromodynamics, published in Physics Reports in 1978. The research of Marciano and Sirlin was important for experiments at BNL for the precise determination of the anomalous magnetic moment of the muon and the precise calculation of the masses of the W and Z bosons involved in electroweak interactions; such calculations are important for estimating the mass of the Higgs boson. In neutrino physics, Marciano and his collaborators proposed novel neutrino experiments with very long transmission distances around 2500 km from the neutrino generation in accelerators to neutrino detectors in mines. Marciano became in 1986 a fellow of the American Physical Society and received in 2001 an Alexander von Humboldt Award. In 2002 he received, jointly with Alberto Sirlin, the Sakurai Prize for "their pioneering work on radiative corrections, which made precision electroweak studies a powerful method of probing the Standard Model and searching for new physics."

Worked examples

Example 1 — a first encounter with William Marciano

Start with the simplest possible case. Write down what William Marciano claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to William Marciano before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about William Marciano ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of William Marciano

In research: William Marciano appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses William Marciano in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: William Marciano is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, 20th-century American physicists, 21st-century American physicists, so understanding it makes those chapters shorter.
In everyday life: Look for William Marciano outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
