John Hopps (physicist)

John Hopps (physicist) 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 John Hopps (physicist) rather than just read about it. In short: John H. Hopps (1939 – May 14, 2004) was an American physicist and politician.

Key takeaways

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

Reference excerpt

John H. Hopps (1939 – May 14, 2004) was an American physicist and politician. A native of Dallas, Texas, Hopps was a Ford Scholar to Morehouse College, also receiving degrees from the Massachusetts Institute of Technology (where he was a member of Omega Psi Phi fraternity) and Brandeis University. After his graduation in 1971, Hopps joined the faculty at Ohio State University, and later accepted a research position in nuclear engineering at MIT, and was a member of leadership at the Charles Stark Draper Laboratory. In 1992, Hopps joined the National Science Foundation, where he was director of the division of materials sciences, and in 1995 returned to Morehouse, where he became provost and senior vice-president. Hopps was appointed by President George W. Bush as deputy Undersecretary of Defense, in 2001, where he oversaw research for defense and engineering, a position he held until his death on 14 May 2004 in Potomac, Maryland.

Worked examples

Example 1 — a first encounter with John Hopps (physicist)

Start with the simplest possible case. Write down what John Hopps (physicist) 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 John Hopps (physicist) 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 John Hopps (physicist) 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 John Hopps (physicist)

In research: John Hopps (physicist) 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 John Hopps (physicist) 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: John Hopps (physicist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, 2004 deaths, 20th-century African-American scientists, so understanding it makes those chapters shorter.
In everyday life: Look for John Hopps (physicist) 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.
