John Meadows Jackson is a astronomy 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 Meadows Jackson rather than just read about it. In short: Dr John Meadows Jackson FRSE FIMA FRAS (1907–1998) was a British mathematician. Life He was born in Chorlton-cum-Hardy on the edge of Manchester on 8 February 1907.

Key takeaways

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

Reference excerpt

Dr John Meadows Jackson FRSE FIMA FRAS (1907–1998) was a British mathematician.

Life He was born in Chorlton-cum-Hardy on the edge of Manchester on 8 February 1907. His mother died during his birth and he was raised by his grandparents. He was educated at Manchester Grammar School having won a scholarship on the basis of his intellect. He obtained two BSc degrees at the University of London: Physics in 1927 and Mathematics in 1928. He won a further scholarship, enabling him to undertake postgraduate studies at Trinity College, Cambridge, under Sir Nevill Mott where he obtained a PhD in Physics in 1933. He then took a job as Assistant Lecturer at Manchester University. He began lecturing in Mathematics at Westfield College in London in 1937. At that time the college was exclusively for women. His career was interrupted by the Second World War. Westfield College was relocated to Oxfordshire in 1939 to avoid bombing. In 1941 he was seconded to the Mine Design Department of the Admiralty based in Helensburgh. The department later relocated to Fettes College in Edinburgh where he worked on the design of mine-sweeping equipment. At the end of the war the family decided not to return to London but to stay in Scotland. In January 1946 he began lecturing in Mathematics at University College, Dundee, initially living with his family in Wormit in Fife on the opposite side of the Tay estuary. He was elected a Fellow of the Royal Society of Edinburgh in 1947. His proposers were Edward Copson, George Dawson Preston, Robert Campbell Garry, and Robert Percival Cook. He retired in 1974 and died at his home, the Cedars on Perth Road in Dundee, on 23 March 1998.

Family In 1940 he was married to Pat Harris, a lecturer in Chemistry whom he had met at a conference in 1938. They had three daughters: Kathleen, Esther and Margaret.

Worked examples

Example 1 — a first encounter with John Meadows Jackson

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

In research: John Meadows Jackson appears in astronomy 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 Meadows Jackson 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 Meadows Jackson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1907 births, 1998 deaths, 20th-century British physicists, so understanding it makes those chapters shorter.
In everyday life: Look for John Meadows Jackson 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.
