Reference excerpt

Thomas Johnson (27 February 1863 – 9 September 1954) was an English botanist and academic renowned as an expert and cataloguer of the world's algae, fungi, and fossil plants.

Biography Johnson was born in Barton-upon-Humber, Lincolnshire, in 1863. He attended Elmfield College in Heworth, York and, after additional study, received an appointment in 1890 as Professor of Botany at Ireland's largest institution of higher learning, Catholic University of Ireland which, in 1909, became University College Dublin. In his 36-year tenure in the post he instructed generations of future botanists and other scientists, oversaw the expansion of the National Herbarium and was instrumental in the founding of the first seed testing station for Britain and Ireland. He also supervised and conducted research on economic botany, served on committees charged with advancing scientific learning in Ireland and was a pioneer in the study of phytopathology, the scientific study of plant diseases. He served as vice president of the Royal Irish Academy. He was made a Fellow of the Linnean Society of London in 1890. In 1902, Matilda Cullen Knowles was appointed a temporary assistant in the then Botanical Section of the National Science and Art Museum. She worked closely with Johnson to continue the development of the Herbarium collection. She also co-authored with him the Hand List of Irish Flowering Plants and Ferns (1910). Johnson retired in 1923, allowing Knowles to take over curatorship, despite 'Assistant Keeper' being her job title.

Personal life Johnson married Bessie Stratton Rowe, daughter of Rev. W. Rowe of Toronto. They had two sons, Lt. Col. Reginald Johnson RAMC (1888–1941) and Capt. Thomas William Gerald Johnson (1893–1976), and a daughter, Thirza Mary Patricia Johnson (1894–1955). His eldest son was a physician with the Royal Army Medical Corps and was killed in action in the Second World War, while his younger son was awarded the Military Cross during the First World War for bravery during the Gallipoli Campaign while serving with the 5th (Service) battalion of the Connaught Rangers. Thomas Johnson died in 1954 in Dublin, and was interred at Deans Grange Cemetery.

Worked examples

Example 1 — a first encounter with Thomas Johnson (botany teacher)

Start with the simplest possible case. Write down what Thomas Johnson (botany teacher) 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 Johnson (botany teacher) 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 Johnson (botany teacher) 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 Johnson (botany teacher)

In research: Thomas Johnson (botany teacher) 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 Johnson (botany teacher) 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 Johnson (botany teacher) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1863 births, 1954 deaths, Academics of University College Dublin, so understanding it makes those chapters shorter.
In everyday life: Look for Thomas Johnson (botany teacher) 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.
