John Frederick Clarke is a science 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 Frederick Clarke rather than just read about it. In short: John Frederick Clarke FRS (1 May 1927 – 11 June 2013) was a professor, an aeronautical engineer, and a pilot. Training and education He was trained in the Fleet Air Arm as a Navy Pilot and then in the Royal Air force at Lossiemouth.

Key takeaways

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

Reference excerpt

John Frederick Clarke FRS (1 May 1927 – 11 June 2013) was a professor, an aeronautical engineer, and a pilot.

Training and education He was trained in the Fleet Air Arm as a Navy Pilot and then in the Royal Air force at Lossiemouth. He left the Navy and worked for a few months at Armstrong Siddeley, then studied aeronautical engineering at Queen Mary University of London in 1949. His thesis advisor Norman A.V. Piercy died in 1953, and he was temporarily advised by Leslie G. Whitehead and then by Alec David Young. He received his PhD in 1957.

Career Clarke worked for English Electric company from 1955 to 1957. In 1958 he joined Cranfield University as a lecturer and stayed there till 1991. After his retirement he continued to do research for a decade. His research interests included Shock waves, detonations, gas dynamics and flame theory.

Awards and honours Clarke was elected a Fellow of the Royal Society in 1982. His nomination reads: Professor Clarke is distinguished particularly for his analytical work on the gas dynamics of reacting flows. He has shown how, in the presence of solid boundaries, flows are affected by dissociation, heat conduction and by relaxation of the internal molecular modes. On flame structure he has used perturbation techniques to obtain realistic models in various geometries and has been able to show good agreement with experimental results; he has also studied explosive atmospheres under the influence of various disturbances. His work on supersonic flow has included analyses of shock structure in reacting gases as well as shockless flow with attached flame sheets. Apart from reacting gases he has worked on unsteady aerodynamics both of wing-bodies and of pipe flows.

Personal life Clarke married Jean Gentle in 1953.

Worked examples

Example 1 — a first encounter with John Frederick Clarke

Start with the simplest possible case. Write down what John Frederick Clarke claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Frederick Clarke 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 Frederick Clarke 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 Frederick Clarke

In research: John Frederick Clarke appears in science 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 Frederick Clarke 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 Frederick Clarke is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1927 births, 2013 deaths, British scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for John Frederick Clarke 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.
