Harold Henry Plough

Harold Henry Plough is a biology 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 Harold Henry Plough rather than just read about it. In short: Harold Henry Plough (April 5, 1892 – November 12, 1985) was an American biologist and a professor at Amherst College. He worked on a range of topics including genetics, examining mutations and marine organisms.

Key takeaways

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

Reference excerpt

Harold Henry Plough (April 5, 1892 – November 12, 1985) was an American biologist and a professor at Amherst College. He worked on a range of topics including genetics, examining mutations and marine organisms. He was a student of T. H. Morgan. Plough was born in New York city and went to Amherst College and on graduating he went to Columbia University in 1913. He received an MA in 1915 and a PhD two years later with a thesis on The effect of temperature on crossing-over in Drosophila. He joined the biology department of Amherst College, rose to the position of professor and worked there until his retirement. He was involved in recruiting H. J. Muller to Amherst College in 1940. Muller was considered as an "undesirable communist sympathizer" and he left Amherst College in 1945, a year before he received a Nobel Prize. Plough worked on the genetics of Drosophila at T. H. Morgan's laboratory in the Marine Biological Laboratory, Woods Hole. He studied radiation and heat induced mutations and was a member of the United States Atomic Energy Commission (1951-53). He had an interest in the Ascidians and after retirement, he published a book on the Sea Squirts of the Atlantic Continental Shelf in 1976.

Worked examples

Example 1 — a first encounter with Harold Henry Plough

Start with the simplest possible case. Write down what Harold Henry Plough claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Harold Henry Plough 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 Harold Henry Plough 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 Harold Henry Plough

In research
Harold Henry Plough appears in biology 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 Harold Henry Plough 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
Harold Henry Plough is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1892 births, 1985 deaths, 20th-century American people, so understanding it makes those chapters shorter.
In everyday life
Look for Harold Henry Plough 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.
