Michael H. Hart

Michael H. Hart is a physics 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 Michael H. Hart rather than just read about it. In short: Michael H. Hart (born April 27, 1932) is an American author, astrophysicist and white nationalist.

Key takeaways

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

Reference excerpt

Michael H. Hart (born April 27, 1932) is an American author, astrophysicist and white nationalist. Since 1978, he has published five books, most notably the best-selling work, The 100: A Ranking of the Most Influential Persons in History.

Fermi paradox Hart published in 1975 a detailed examination of the Fermi paradox: the contrast between the extreme likelihood of extraterrestrial life somewhere in the universe and the total absence of any evidence for this. Hart's work has prompted several papers as answers. Geoffrey A. Landis writes: "A more proper name for [the paradox] would be the Fermi-Hart paradox, since while Fermi is credited with first asking the question, Hart was the first to do a rigorous analysis showing that the problem is not trivial, and also the first to publish his results". Robert H. Gray views Hart as the proper originator of this argument, in Hart's 1975 paper. Gray argues that the term Fermi paradox is a misnomer; that it is not the work of Fermi, nor is it an actual paradox (rather an argument). He therefore proposes that, instead of the (standard, but in his view incorrect) name Fermi paradox, it should be known as the Hart-Tipler argument – acknowledging Hart's priority as the argument's originator, but also acknowledging Frank J. Tipler's substantial extension of Hart's arguments in his 1980 paper "Extraterrestrial intelligent beings do not exist".

Hart is an advocate of the Rare Earth hypothesis; he proposed a very narrow habitable zone based on climate studies. He advocated for this hypothesis in the book which he co-edited, "Extraterrestrials: Where are They", in particular in the chapter he contributed to it "Atmospheric Evolution, the Drake Equation and DNA: Sparse Life in an Infinite Universe".

The 100: A Ranking of the Most Influential Persons in History

Hart's first book was The 100: A Ranking of the Most Influential Persons in History (1978), which has sold more than 500,000 copies and been translated into many languages. The first person on Hart's list was Muhammad, chosen over Jesus or Moses. Hart attributes this to the fact that Muhammad was "supremely successful" in both the religious and secular realms. He also accredits Muhammad for his role in the development of Islam, far more influential than Jesus' contribution to the development of Christianity. Hart claims that Paul the Apostle was more pivotal than Jesus to the growth of Christianity.

White nationalism Hart has described himself as a white separatist and is active in white separatist causes. In 1996, he addressed a conference organized by Jared Taylor's white separatist organization, New Century Foundation, publisher of American Renaissance. He proposed partitioning the United States into four states: a white state, a black state, a Hispanic state, and an integrated mixed-race state. At the 2006 American Renaissance conference, Hart, who is Jewish, had a public confrontation with David Duke, the former Grand Wizard of the Ku Klux Klan and former Louisiana state representative, over Duke's antisemitic remarks. Hart then stood up, called Duke a Nazi and stormed out. Some participants jeered at Hart. After this incident, Hart left American Renaissance. In 2009, Hart organized a racist conference in Baltimore with the title Preserving Western Civilization. It was billed as addressing the need to defend "America's Judeo-Christian heritage and European identity." Invited speakers included: Lawrence Auster, Peter Brimelow, Steven Farron, Julia Gorin, Lino A. Graglia, Henry C. Harpending, Roger D. McGrath, Pat Richardson, J. Philippe Rushton, Srdja Trifković, and Brenda Walker. In this conference, Hart compared the Qur'an to Mein Kampf and Islam to Nazism.

Worked examples

Example 1 — a first encounter with Michael H. Hart

Start with the simplest possible case. Write down what Michael H. Hart 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 Michael H. Hart 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 Michael H. Hart 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 Michael H. Hart

In research
Michael H. Hart 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 Michael H. Hart 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
Michael H. Hart is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 20th-century American science writers, Adelphi University alumni, so understanding it makes those chapters shorter.
In everyday life
Look for Michael H. Hart 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.
