Jack Hollander

Jack Hollander is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Jack Hollander rather than just read about it. In short: Jack Marvin Hollander (April 13, 1927 – November 10, 2019) was an American nuclear physicist. He held various positions in nuclear physics, energy, environmental research, and academic administration throughout his career.

Key takeaways

  • Jack Hollander belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Jack Hollander to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Jack Hollander from memory before moving on to harder problems.

Reference excerpt

Jack Marvin Hollander (April 13, 1927 – November 10, 2019) was an American nuclear physicist. He held various positions in nuclear physics, energy, environmental research, and academic administration throughout his career. He was also the founding editor of the academic journal the Annual Review of Energy (now the Annual Review of Environment and Resources).

Early life and education Jack M. Hollander was born into a family of Eastern European Jewish immigrants on April 13, 1927, in Youngstown, Ohio. He was born to parents Adele née Feuer and Isadore Hollander, and had two older siblings, Maurice (born 1922) and Louise (born 1924). Isadore Hollander had immigrated from Hungary as a young child, and Adele Feuer had immigrated from Romania as a teenager; they met at a social at a Jewish center. Isadore was an accountant, and Adele was a volunteer nurse during World War I. Jack Hollander attended Ohio State University, graduating with a bachelor's degree in chemistry in 1948. He then attended the University of California, Berkeley, graduating with a PhD in nuclear chemistry in 1951.

Career In 1968, Hollander was one of the cofounders of the environmental research program at Lawrence Berkeley Laboratory. From 1973 to 1976, he was the first director of the lab's Energy and Environment Division. In 1980, he was a cofounder of the American Council for an Energy-Efficient Economy. From 1979 to 1983, he was the first director of the University of California Energy Institute. He was the chairperson of the Beijer Institute of Energy and Human Ecology from 1976 to 1988. He worked at Ohio State University as vice president for research and graduate studies from 1983 to 1989. He was the founding editor of the peer-reviewed journal the Annual Review of Energy, which was first published in 1976. He remained the editor until 1992.

Awards and honors Hollander received two Guggenheim Fellowships, both in the natural sciences category and the field of physics. The first was in 1958 and the second was in 1965. He was elected a fellow of American Association for the Advancement of Science in 1980 and the American Physical Society in 1987 "for founding and directing research programs on energy and the environment and for taking a leading role in the study of global energy resources and requirements".

Personal life and death Hollander's first wife was Margie Schnarr Hollander, with whom he had three children. He later married pianist Sharon Mann, the mother of his two stepchildren, on December 31, 1985. He died on November 10, 2019, in Berkeley, California, at the age of 92.

Worked examples

Example 1 — a first encounter with Jack Hollander

Start with the simplest possible case. Write down what Jack Hollander 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 Jack Hollander 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 Jack Hollander 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 Jack Hollander

In research
Jack Hollander 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 Jack Hollander 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
Jack Hollander is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1927 births, 2019 deaths, American people of Hungarian-Jewish descent, so understanding it makes those chapters shorter.
In everyday life
Look for Jack Hollander 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.
