John Comrie

John Comrie 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 Comrie rather than just read about it. In short: John Dixon Comrie (28 February 1875 – 2 October 1939) was a Scottish physician, historian of medicine, and the editor of the first edition of Black's Medical Dictionary. Biography Comrie studied at George Watson's College and the University of Edinburgh, graduating with M.B. degree and first-class honours in 1899.

Key takeaways

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

Reference excerpt

John Dixon Comrie (28 February 1875 – 2 October 1939) was a Scottish physician, historian of medicine, and the editor of the first edition of Black's Medical Dictionary.

Biography Comrie studied at George Watson's College and the University of Edinburgh, graduating with M.B. degree and first-class honours in 1899. He became a Fellow of the Royal College of Physicians in 1906 and took a M.D. degree from Edinburgh in 1911, before positions in the Edinburgh and Glasgow Infirmaries. After that he did post-graduate studies in Berlin and Vienna, worked as clinical assistant at the National Hospital in London, and finally settled at Edinburgh, where he became known as pathologist, physician to the Royal Infirmary, and consulting physician to the Deaconess Hospital and the Princess Margaret Rose Hospital for Crippled Children. During World War I he acted as consulting physician to the North Russian Expeditionary Force, reaching the rank of Lieutenant-Colonel. His father was also John Dixon Comrie (died before October 1939). In 1929 he was elected a member of the Harveian Society of Edinburgh and in 1932 he was elected a member of the Aesculapian club. In 1933, Comrie authored Diet in Health and Sickness which was positively reviewed in the British Medical Journal as a reliable guide to dietetics for practitioners.

Worked examples

Example 1 — a first encounter with John Comrie

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

In research: John Comrie 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 Comrie 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 Comrie is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1875 births, 1939 deaths, 20th-century Scottish medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for John Comrie 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.
