Reference excerpt

Thomas Lincoln Casey Jr. (February 19, 1857 – February 3, 1925) was an American army engineer and entomologist who was noted for his work on Coleoptera. He was the eldest son of Brigadier General Thomas Lincoln Casey (1831–1896), who served as Chief of Engineers for the United States Army Corps of Engineers and oversaw the completion of the Washington Monument.

Military career Casey was born in West Point, New York. He followed in his father's footsteps and attended the United States Military Academy at West Point. He entered the academy in 1875 and graduated second in his class in 1879, when he was commissioned a 2nd lieutenant in the Corps of Engineers. He was promoted to 1st lieutenant in June 1881 and to captain in July 1888. From 1895 he was assigned to construction of fortifications at Fort Monroe and the Hampton Roads area in Virginia. In July 1898, he was promoted to major and supervised the installation of underwater mines to defend Hampton Roads during the Spanish–American War. He then served at Vicksburg, Mississippi from 1899 to 1901 and was in charge of Mississippi river improvements at St. Louis, Missouri from 1901 to 1906. In 1906, he was promoted to lieutenant colonel. In 1909, he was promoted to colonel and assigned as engineer secretary to the Lighthouse Board until 1910. Casey retired from the army on November 1, 1912.

Scientific work He published numerous scientific papers on the subject of Coleoptera and a monograph, Memoirs on the Coleoptera (1910–1924). He was also known for contributions to astronomy.

Later life Casey died on February 3, 1925 in Washington, D.C. He was interred at Arlington National Cemetery three days later.

Worked examples

Example 1 — a first encounter with Thomas Lincoln Casey Jr.

Start with the simplest possible case. Write down what Thomas Lincoln Casey Jr. 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 Thomas Lincoln Casey Jr. 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 Thomas Lincoln Casey Jr. 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 Thomas Lincoln Casey Jr.

In research: Thomas Lincoln Casey Jr. 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 Thomas Lincoln Casey Jr. 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: Thomas Lincoln Casey Jr. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1857 births, 1925 deaths, American astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Thomas Lincoln Casey Jr. 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.
