Richard Bradfield

Richard Bradfield 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 Richard Bradfield rather than just read about it. In short: Richard Bradfield (April 29, 1896 – May 1, 1981) was an American agronomist instrumental in the early formation of the Green Revolution. Bradfield was one of three scientists, along with Elvin Stakman and Paul Mangelsdorf, commissioned by the Rockefeller Foundation in 1941 to make recommendations on increasing agricultural yields in Mexico.

Key takeaways

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

Reference excerpt

Richard Bradfield (April 29, 1896 – May 1, 1981) was an American agronomist instrumental in the early formation of the Green Revolution. Bradfield was one of three scientists, along with Elvin Stakman and Paul Mangelsdorf, commissioned by the Rockefeller Foundation in 1941 to make recommendations on increasing agricultural yields in Mexico. Their initial work developed into the Mexican Agriculture Program, out of which the Green Revolution emerged.

A native of West Jefferson, Ohio, Bradfield studied at Otterbein and Ohio State University before joining the faculty at University of Missouri. Bradfield served as a professor at Cornell University in soil technology from 1937 to 1961. Bradfield Hall, an fifteen-story Brutalist tower designed by Ulrich Franzen, is named in his honor.

Worked examples

Example 1 — a first encounter with Richard Bradfield

Start with the simplest possible case. Write down what Richard Bradfield 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 Richard Bradfield 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 Richard Bradfield 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 Richard Bradfield

In research: Richard Bradfield 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 Richard Bradfield 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: Richard Bradfield is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1981 deaths, 20th-century American agronomists, Cornell University faculty, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Bradfield 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.
