Key takeaways

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

Reference excerpt

John Merton Aldrich (January 28, 1866 – May 27, 1934) was an American entomologist. Aldrich was the Associate Curator of Insects at the United States National Museum. He is considered one of the most prolific entomologists in the study of flies.

Biography John Merton Aldrich was born in Rochester, Minnesota on January 28, 1866. When he was fifteen, he moved with his family to a farm in South Dakota. He enrolled at South Dakota State University and graduated in 1888, one year early because the university president wanted to have a graduating class that year. He studied entomology briefly under Otto Lugger at the University of Minnesota and then started working at the South Dakota State Agricultural Experiment Station with the understanding that he would continue to study entomology in the winter. In 1889 he enrolled at Michigan State University and studied with entomologist Albert J. Cook. Cook suggested that he focus his studies on a single order of insects; Aldrich followed his advice and focused his career on Diptera (flies). In 1891, Aldrich was awarded an M.S. from South Dakota State University. In 1892, Aldrich traveled to the University of Kansas where he was befriended by Samuel W. Williston who lent him money and encouraged him to stay at his house. The University awarded Aldrich a second M.S. and in 1893 he left Kansas to become the first zoology professor at the University of Idaho. In Idaho he worked on economic entomology while maintaining a focus on flies. He began to assemble his most important work, Catalogue of the North American Diptera, published by the Smithsonian in 1905. His catalog described 8.300 flies and was considered a landmark study of Diptera in America. In 1893, he married Ellen J. Roe from Brookings, South Dakota, but after only four years of marriage, his wife and their infant son died. In 1905 he remarried to Dell Smith of Moscow, Idaho. In 1906, Aldrich took a sabbatical to attend Stanford University where he submitted his Catalogue as a doctoral thesis and was awarded a Ph.D. in 1907. When he returned to Idaho he found that a fire had destroyed the university. Fortunately for Aldrich, he had stored his personal library and insect collections off-campus. Aldrich continued to work at the University of Idaho for another six years. In 1913 he became embroiled in the politics of academia and was terminated along with four other professors for accusing the university president of incompetence. One biographer later called the dismissal "an outrageous and unwarranted interference." Aldrich had a national reputation as a talented entomologist and he was quickly hired into the USDA Bureau of Entomology and stationed in Lafayette, Indiana. There he spent the next five years studying the agricultural pests of cultivated grains. He also wrote an important monograph on the Sarcophaga and Allies in North America (1916). After the death of Frederick Knab in 1918, Aldrich became the Associate Curator of Insects and the Custodian of Diptera at the United States National Museum in Washington, D.C., a position he held until his death Throughout his career, Aldrich was a prolific collector of insects and was known for his ability to find rare species. He collected widely in the western United States, Alaska, Canada, Europe and Guatemala. Many his specimens were new to science. His expertise made the National Museum a center for studies on New World Diptera. In 1928, Aldrich presented his collection of more than 45,000 specimens and more than 4,000 named species to the museum. He also donated to the museum a card catalog file of North American literature on these specimens. His collection is one of the most important general Diptera collections in the National Museum.

Later life Aldrich was active in the All Souls Unitarian-Universalist Church in Washington, D.C., where he taught religion classes. He co-founded the Thomas Say Foundation. He served as curator and custodian at the United States National Museum until his death in 1934. His archival collections are held in the Smithsonian Institution Archives. He died suddenly on May 27, 1934. He was buried in Moscow, Idaho.

Worked examples

Example 1 — a first encounter with John Merton Aldrich

Start with the simplest possible case. Write down what John Merton Aldrich 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 John Merton Aldrich 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 John Merton Aldrich 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 John Merton Aldrich

In research
John Merton Aldrich 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 John Merton Aldrich 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
John Merton Aldrich is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1866 births, 1934 deaths, American entomologists, so understanding it makes those chapters shorter.
In everyday life
Look for John Merton Aldrich 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.
