Key takeaways

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

Reference excerpt

John Charles Fields, FRS, FRSC (May 14, 1863 – August 9, 1932) was a Canadian mathematician and the founder of the Fields Medal for outstanding achievement in mathematics.

Career Born in Hamilton, Canada West, to a leather shop owner, Fields graduated from Hamilton Collegiate Institute in 1880 and University College, University of Toronto in 1884 before leaving for the United States to study at Johns Hopkins University in Baltimore, Maryland. Fields received his Ph.D. in 1887. His thesis, entitled Symbolic Finite Solutions and Solutions by Definite Integrals of the Equation dny/dxn = xmy, was published in the American Journal of Mathematics in 1886. Fields taught for two years at Johns Hopkins before joining the faculty of Allegheny College in Meadville, Pennsylvania. Disillusioned with the state of mathematical research in North America at the time, he left for Europe in 1891, locating primarily in Berlin, Göttingen and Paris, where he associated with some of the greatest mathematical minds of the time, including Karl Weierstrass, Felix Klein, Ferdinand Georg Frobenius and Max Planck. Fields also began a lifelong friendship with Gösta Mittag-Leffler. He began publishing papers on a new topic, algebraic functions, which would prove to be the most fruitful research field of his career. Fields returned to Canada in 1902 to lecture at the University of Toronto. Back in the country of his birth, he worked tirelessly to raise the status of mathematics within academic and public circles. He successfully lobbied the Ontario Legislature for an annual research grant of $75,000 for the university and helped establish the National Research Council of Canada, and the Ontario Research Foundation. Fields served as president of the Royal Canadian Institute from 1919 until 1925, during which time he aspired to mold the institute into a leading centre of scientific research, although with mixed success. His efforts, however, were pivotal in making Toronto the location of the 1924 International Congress of Mathematicians (ICM). He was an Invited Speaker of the ICM in 1912 at Cambridge, in 1924 at Toronto, and in 1928 at Bologna. Fields is best known for his development of the Fields Medal, which is considered by some to be the Nobel Prize of mathematics, although there are differences between the awards. First awarded in 1936, the medal was reintroduced in 1950 and has been awarded every four years since. It is awarded to two, three or four mathematicians under the age of 40 who have made important contributions to the field. Fields began planning the award in the late 1920s but, due to deteriorating health, never saw the implementation of the medal in his lifetime. He died on August 9, 1932, after a three-month illness; in his will, he left $47,000 for the Fields Medal fund. His plan for the Fields medal was completed by J. L. Synge.

Honours Fields was elected a fellow of the Royal Society of Canada in 1907 and of the Royal Society of London in 1913. The Fields Institute at the University of Toronto was named in his honour.

Worked examples

Example 1 — a first encounter with John Charles Fields

Start with the simplest possible case. Write down what John Charles Fields 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 Charles Fields 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 Charles Fields 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 Charles Fields

In research
John Charles Fields 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 Charles Fields 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 Charles Fields is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1863 births, 1932 deaths, Academic staff of the University of Toronto Faculty of Arts and Science, so understanding it makes those chapters shorter.
In everyday life
Look for John Charles Fields 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.
