Mayo D. Hersey

Mayo D. Hersey 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 Mayo D. Hersey rather than just read about it. In short: Mayo Dyer Hersey (August 30, 1886 – September 5, 1978) was an American engineer, physicist at the National Bureau of Standards and other government agencies, and Professor of Engineering at Brown University. He received the 1957 ASME Medal, and the first Mayo D.

Key takeaways

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

Reference excerpt

Mayo Dyer Hersey (August 30, 1886 – September 5, 1978) was an American engineer, physicist at the National Bureau of Standards and other government agencies, and Professor of Engineering at Brown University. He received the 1957 ASME Medal, and the first Mayo D. Hersey award in 1965.

Biography

Youth, education and early career Hersey was born in Pawtuxet Neck in Providence County, Rhode Island, in 1886, son of George Milbank Hersey and Alice Stafford (Budlong) Hersey. He obtained his Bsc from Colorado College in 1907, and in 1910 both his BSc in mechanical engineering from Massachusetts Institute of Technology, and his MSc in physics and mathematics from Olivet College. After his graduation in 1910 Hersey started his career as physicist at the National Bureau of Standards, now National Institute of Standards and Technology. He also started teaching at the Massachusetts Institute of Technology from 1910 to 1922. In World War I he did research on aeronautical instruments for the National Bureau of Standards.

Further career and acknowledgement After leaving the National Bureau of Standards in 1920, Hersey was appointed at the U.S. Bureau of Mines in Pittsburgh as chief of the physical laboratory from 1922 to 1926. From 1936 to 1951 Hersey was back at the National Bureau of Standards. In World War II he served as a consultant to the Manhattan Project at Columbia. From 1947 to 1957 he also worked as scholar for the Naval Engineering Experiment Station at Annapolis, and then retired from government service. From 1934 to 1936 Hersey had lectured at Brown University, and from 1943 to 1945 he had been a scholar at Columbia University. From 1957 until his death in 1978 he had been visiting professor in engineering at Brown University. He received the Society of Tribologists and Lubrication Engineers International Award in 1951. In 1965 the ASME initiated the annual Mayo D. Hersey award for "distinguished and continued contributions over a substantial period of time to the advancement of the science and engineering of tribology," and Hersey was named its first recipient. In 1967 the ASME also awarded him the ASME Medal. In 1974, the Institution of Mechanical Engineers awarded him the Tribology Gold Medal.

Worked examples

Example 1 — a first encounter with Mayo D. Hersey

Start with the simplest possible case. Write down what Mayo D. Hersey 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 Mayo D. Hersey 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 Mayo D. Hersey 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 Mayo D. Hersey

In research: Mayo D. Hersey 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 Mayo D. Hersey 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: Mayo D. Hersey is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1886 births, 1978 deaths, 20th-century American engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Mayo D. Hersey 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.
