Reference excerpt

Mael Avrami Melvin (1913 – October 1, 2014) was an American physicist. His initial research was in metallurgy and materials science. In this area he is best known for the Avrami equation and for the Melvin metric. After his defense work in World War II he dropped out of science for a while and changed his name. His later work was in many fields of physics and he was elected a Fellow of the American Physical Society.

Early life and education Avrami was born in Palestine in 1913 to American parents who were visiting the country. He was originally named Moshe Yoel Avrami, but his parents changed his name to Melvin when they returned to the United States. He studied theoretical physics at the University of Chicago where he received a B.S. in 1933, a M.S. in 1935 and a Ph.D. in 1938. While completing his doctoral education he worked at U. S. Steel's Gary Works as a metallurgist.

Career Melvin left the steel industry in 1938 when he took up a faculty position at Columbia University and worked in the physics and metallurgy departments. After a sabbatical from 1948 to 1952, in which he worked on the application of a theory of generalized symmetry to quantum theory and electrodynamics, he joined the Florida State University as a professor of physics.

In 1947 he changed his name to Mael Avrami Melvin. From 1966 until his retirement he was professor at Temple University.

He died on October 1, 2014, in Santa Barbara, California.

Worked examples

Example 1 — a first encounter with Mael Avrami Melvin

Start with the simplest possible case. Write down what Mael Avrami Melvin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Mael Avrami Melvin 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 Mael Avrami Melvin 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 Mael Avrami Melvin

In research: Mael Avrami Melvin appears in astronomy 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 Mael Avrami Melvin 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: Mael Avrami Melvin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 2014 deaths, 20th-century American physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Mael Avrami Melvin 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.
