Gotthilf Hempel

Gotthilf Hempel 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 Gotthilf Hempel rather than just read about it. In short: Gotthilf Hempel (born March 8, 1929) is a German marine biologist and oceanographer. He helped to initiated 1981 the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven and in 1992 of the Leibnitz Center for Tropical Marine Research.

Key takeaways

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

Reference excerpt

Gotthilf Hempel (born March 8, 1929) is a German marine biologist and oceanographer. He helped to initiated 1981 the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven and in 1992 of the Leibnitz Center for Tropical Marine Research.

Live Hempel studied biology and geology at the universities of Mainz and Heidelberg.[1] In 1952 he gained his Ph.D. with a study on the energetics of grasshopper jumps[2] from Heidelberg University. He then went on to work as a scientific assistant at various research institutes in Wilhelmshaven, Heligoland, and Hamburg, where he habilitated with a thesis on the ecology of fry in 1963.[3] In 1967 he became a professor at the University of Kiel at the Institute of Marine Sciences (Institut für Meereskunde Kiel), where he remained director of the Department of Fisheries Biology for the next 14 years and served as Acting Director of the institute from 1972 to 1976. In 1981, he helped found the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven whereupon he became the institution's first director. In the same year, he also became director of the Institute for Polar Ecology at the University of Kiel. In Bremerhaven, he initiated the construction of the polar research vessel PFS Polarstern. In 1992, he became the first director of the then newly founded Center for Marine Tropical Ecology at this time part of University of Bremen. Hempel retired in 1994. He has been interested and active in research politics throughout his career. From 1963 to 1967 he worked for UNESCO and the FAO and from 1990 to 1996 he was a member of the Wissenschaftsrat, the scientific advisory committee of Germany. He has been and is an active proponent of scientific collaboration and education initiatives in underdeveloped countries, and has advocated a more sustainable exploitation of natural resources. Hempel is the editor of the journal Polar Biology, and he has also published several books. He has had more than 70 doctoral candidates, notably Daniel Pauly. From his time spent researching oceanological topics he has managed to spend over 1000 days aboard research vessels. He became a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1989. He was awarded the German Order of Merit (Grosses Verdienstkreuz) in 1993.

Worked examples

Example 1 — a first encounter with Gotthilf Hempel

Start with the simplest possible case. Write down what Gotthilf Hempel 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 Gotthilf Hempel 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 Gotthilf Hempel 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 Gotthilf Hempel

In research: Gotthilf Hempel 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 Gotthilf Hempel 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: Gotthilf Hempel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 20th-century German zoologists, Academic staff of the University of Bremen, so understanding it makes those chapters shorter.
In everyday life: Look for Gotthilf Hempel 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.
