Reference excerpt

George Jarvis Brush (December 15, 1831 – February 5, 1912) was an American mineralogist and academic administrator who spent most of his career at Yale University in the Sheffield Scientific School.

Career Brush was born in Brooklyn, New York on December 15, 1831. He studied at Cream Hill Agricultural School and commenced his studies at Yale in 1848 with courses from Benjamin Silliman, Jr. and John Pitkin Norton on practical chemistry and agriculture. He also studied chemistry, metallurgy and mineralogy. He left in 1850 to work with Benjamin Silliman, Jr. but received his Ph.D. from Yale in 1852 by special examination. From 1852 to 1855, Brush worked and studied at the University of Virginia and in Munich and Freiberg. He returned to Sheffield in 1855 to join the faculty as professor of Metallurgy and later of Mineralogy. Brush had begun acquiring an extensive research collection of minerals. He was appointed the first curator of the Peabody Museum of Natural History's mineral collection. He was a member of the Connecticut Academy of Arts and Sciences. In 1872, he became the first director of Sheffield, where he also supervised mineralogy. He served as the president of the American Association for the Advancement of Science in 1881. He published extensively in the American Journal of Science and other journals. He also published a Manual of Determinative Mineralogy (1875; fifteenth edition, 1899). In 1898, Brush retired from teaching and administration at Sheffield. He continued serving at the school, however, as secretary, treasurer and president of the board, until 1911. In 1904, Brush donated his collection of minerals, along with funds for their maintenance, to Sheffield. Originally housed in Hammond Hall at Yale, the Brush Collection is now administered by the Division of Mineralogy at the Yale Peabody Museum. Brush died in New Haven on February 5, 1912. The mineral brushite was named in his honor by G. E. Moore.

Worked examples

Example 1 — a first encounter with George Jarvis Brush

Start with the simplest possible case. Write down what George Jarvis Brush 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 George Jarvis Brush 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 George Jarvis Brush 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 George Jarvis Brush

In research: George Jarvis Brush 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 George Jarvis Brush 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: George Jarvis Brush is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1831 births, 1912 deaths, 19th-century American science writers, so understanding it makes those chapters shorter.
In everyday life: Look for George Jarvis Brush 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.
