John Enderby

John Enderby 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 Enderby rather than just read about it. In short: Sir John Edwin Enderby (16 January 1931 – 3 August 2021) was a British physicist, and was Professor of Physics at University of Bristol from 1976 to 1996. He developed innovative ways of using neutrons to study matter at the microscopic level.

Key takeaways

John Enderby 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 Enderby to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of John Enderby from memory before moving on to harder problems.

Reference excerpt

Sir John Edwin Enderby (16 January 1931 – 3 August 2021) was a British physicist, and was Professor of Physics at University of Bristol from 1976 to 1996. He developed innovative ways of using neutrons to study matter at the microscopic level. His research has particularly advanced our understanding of the structure of multicomponent liquids— those made up of two or more types of atoms – including commonly used liquid alloys and glasses.

Education Enderby was educated at Chester Grammar School and the University of London where he was awarded Bachelor of Science and Doctor of Philosophy degrees.

Career and research Enderby’s techniques mean that the relative positions of the various types of atomic nuclei can be deduced from diffraction patterns arising from the quantum wavelike scattering of the neutrons. His work includes the surprise discovery that aqueous solutions — important in biology as the environment for an organism’s chemical reactions — have a quasi-lattice structure. He was the H.O. Wills Professor of Physics and Head of Department, from 1981 to 1994 and Deputy Director (Directeur-adjoint) of the Institut Laue–Langevin from 1985 to 1988.

Personal life Enderby died on 3 August 2021, at the age of 90.

Awards and honours Enderby was awarded the Guthrie Medal of the Institute of Physics, an institution he later served as President. Enderby was elected a Fellow of the Royal Society (FRS) in 1985 and was Physical Secretary and Vice-President of the society from 1999 to 2004 and was Chair of the Royal Society's Publishing Board ex officio. He was President of the Institute of Physics from 2004 to 2006. Enderby's contributions have been recognised by the award of a CBE in 1997 and a Knighthood for services to Science and Technology in 2004.

Worked examples

Example 1 — a first encounter with John Enderby

Start with the simplest possible case. Write down what John Enderby 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 Enderby 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 Enderby 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 Enderby

In research: John Enderby 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 Enderby 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 Enderby is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 2021 deaths, Alumni of the University of London, so understanding it makes those chapters shorter.
In everyday life: Look for John Enderby 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.
