Jonathan Partington

Jonathan Partington is a mathematics 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 Jonathan Partington rather than just read about it. In short: Jonathan Richard Partington (born 4 February 1955) is an English mathematician who is Emeritus Professor of pure mathematics at the University of Leeds. Education Professor Partington was educated at Gresham's School, Holt, and Trinity College, Cambridge, where he completed his PhD thesis entitled "Numerical ranges and the Geometry of Banach Spaces" under the supervision of Béla Bollobás.

Key takeaways

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

Reference excerpt

Jonathan Richard Partington (born 4 February 1955) is an English mathematician who is Emeritus Professor of pure mathematics at the University of Leeds.

Education Professor Partington was educated at Gresham's School, Holt, and Trinity College, Cambridge, where he completed his PhD thesis entitled "Numerical ranges and the Geometry of Banach Spaces" under the supervision of Béla Bollobás.

Career Partington works in the area of operator theory and complex analysis, sometimes applied to control theory, and is the author of several books in this area. He was formerly editor-in-chief of the Journal of the London Mathematical Society, a position he held jointly with his Leeds colleague John Truss. Partington's extra-mathematical activities include the invention of the March March march, an annual walk starting at March, Cambridgeshire. He is also known as a writer or co-writer of some of the earliest British text-based computer games, including Acheton, Hamil, Murdac, Avon, Fyleet, Crobe, Sangraal, and SpySnatcher, which started life on the Phoenix computer system at the University of Cambridge Computer Laboratory. These are still available on the IF Archive.

Worked examples

Example 1 — a first encounter with Jonathan Partington

Start with the simplest possible case. Write down what Jonathan Partington claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Jonathan Partington 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 Jonathan Partington 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 Jonathan Partington

In research
Jonathan Partington appears in mathematics 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 Jonathan Partington 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
Jonathan Partington is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 20th-century English mathematicians, 21st-century English mathematicians, so understanding it makes those chapters shorter.
In everyday life
Look for Jonathan Partington 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.
