Reference excerpt

Otto Hilgard Tittmann (August 20, 1850 – August 21, 1938) was an American geodesist, geographer, and astronomer of German descent.

He attended school in St. Louis, and in 1867 joined the United States Coast Survey. In 1874 he was assistant astronomer in Japan to view the Transit of Venus and from 1889 until 1893 he was in charge of weights and measures. In 1888 he co-founded the National Geographic Society. In 1899, Tittmann served as president of the Philosophical Society of Washington. And, from 1895 until 1900 he was assistant in charge of the United States Coast and Geodetic Survey. He was elected to the American Philosophical Society in 1906. From 1900 until 1915 he was Superintendent of the Survey, and from 1915 until 1919 he was president of the National Geographic Society.

Worked examples

Example 1 — a first encounter with Otto Hilgard Tittmann

Start with the simplest possible case. Write down what Otto Hilgard Tittmann 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 Otto Hilgard Tittmann 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 Otto Hilgard Tittmann 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 Otto Hilgard Tittmann

In research: Otto Hilgard Tittmann 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 Otto Hilgard Tittmann 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: Otto Hilgard Tittmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1850 births, 1938 deaths, American astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Otto Hilgard Tittmann 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.
