Thomas Easterfield

Thomas Easterfield 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 Thomas Easterfield rather than just read about it. In short: Sir Thomas Hill Easterfield (4 March 1866 – 1 March 1949) was a New Zealand chemist. Born in Doncaster, England, he was the youngest of four children of Edward Easterfield, savings bank secretary, and Susan (née Hill).

Key takeaways

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

Reference excerpt

Sir Thomas Hill Easterfield (4 March 1866 – 1 March 1949) was a New Zealand chemist. Born in Doncaster, England, he was the youngest of four children of Edward Easterfield, savings bank secretary, and Susan (née Hill). He attended Doncaster Grammar School, and later entered the Yorkshire College of Science, now the University of Leeds. He was then appointed a Senior Foundation Scholar of Clare College, Cambridge, from where he gained First Class honours in the Natural Sciences Tripos in 1886. After graduation Easterfield worked in the Technische Hochschule Zürich, the University of Zürich, and later in the University of Würzburg under Emil Fischer, from where he was awarded a PhD in 1894 for his work on citrazinic acid. In 1888, Easterfield returned to Cambridge as a junior demonstrator in the chemistry department. He was appointed a lecturer in the University Extension programme in 1891 and in 1894 lecturer on pharmaceutical chemistry and chemistry of sanitary science; he was also a master at The Perse School. In 1899, Easterfield was appointed one of the four foundation professors of the Victoria University of Wellington, New Zealand; he and their two daughters set sail for the 90 day voyage on the Kaikoura from Plymouth on 11 February. In 1919 he became the first director of the Cawthron Institute, Nelson; he retired from there in 1933. Easterfield isolated the chemical compounds Totarol, Cannabinol and Tutin.[1] In 1935, he was awarded the King George V Silver Jubilee Medal. He was appointed a Knight Commander of the Order of the British Empire in the 1938 King's Birthday Honours.

Worked examples

Example 1 — a first encounter with Thomas Easterfield

Start with the simplest possible case. Write down what Thomas Easterfield 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 Thomas Easterfield 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 Thomas Easterfield 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 Thomas Easterfield

In research
Thomas Easterfield 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 Thomas Easterfield 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
Thomas Easterfield is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1866 births, 1949 deaths, 20th-century New Zealand scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Thomas Easterfield 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.
