Wolfgang Sternberg

Wolfgang Sternberg 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 Wolfgang Sternberg rather than just read about it. In short: Wolfgang Sternberg (1887–1953) was a German-American mathematician. He completed his doctoral dissertation in 1912 at the University of Breslau and his habilitation in 1920 at Heidelberg University.

Key takeaways

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

Reference excerpt

Wolfgang Sternberg (1887–1953) was a German-American mathematician. He completed his doctoral dissertation in 1912 at the University of Breslau and his habilitation in 1920 at Heidelberg University. He was a professor at Heidelberg from 1920 to 1927 and in Breslau from 1927 to 1933. In 1935 Sternberg was dismissed by the non-Aryan laws from his post at Breslau He briefly went to Palestine. However, in Palestine he was unhappy, due to various factors, such as "Jewish nationalism", lack of knowledge of Hebrew, and bad climate. He worked at the Hebrew University without remuneration, and actively sought possibilities to emigrate to other places, including the United States and the Soviet Union. He wrote to Richard Courant in 1936:

The value of [Palestinian] citizenship is, however, dubious. It is also dependent on whether the rather unpredictable English policies remain friendly to the Jews or not. I admit that an American citizenship would be much preferable to me.

Eventually, Sternberg left Palestine for Prague. From 1935 to 1939, he was a member of the faculty of the Prague German University. In 1939 he managed to reach the United States where he had great difficulty finding employment despite help from Courant. He was living in New York City in 1942. Eventually, he went through a number of temporary jobs at the Cornell University and other places, until his early retirement in 1948. Sternberg made contributions to potential theory, integral equations, and probability theory. Sternberg's two volume book Potentialtheorie I and Potentialtheorie II was published by Walter de Gruyter. Later he published The Theory of Potential and Spherical Harmonics with Turner Smith. Jaroslav Lukeš, Ivan Netuka, and Jiří Veselý describe his "well-known work on the Perron method for the heat equation, "Über die Gleichung der Wärmeleitung" as "often quoted in treatises on modern potential theory."

Worked examples

Example 1 — a first encounter with Wolfgang Sternberg

Start with the simplest possible case. Write down what Wolfgang Sternberg 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 Wolfgang Sternberg 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 Wolfgang Sternberg 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 Wolfgang Sternberg

In research: Wolfgang Sternberg 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 Wolfgang Sternberg 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: Wolfgang Sternberg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1887 births, 1953 deaths, Academic staff of Charles University, so understanding it makes those chapters shorter.
In everyday life: Look for Wolfgang Sternberg 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.
