Marlies Teichmüller

Marlies Teichmüller is a earth science 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 Marlies Teichmüller rather than just read about it. In short: Marlies Teichmüller (born Marie-Luise Barbara Köster; 1914 – 12 September 2000) was a German geologist and coal petrologist. She specialised in the study of coal formation through petrologic analysis.

Key takeaways

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

Reference excerpt

Marlies Teichmüller (born Marie-Luise Barbara Köster; 1914 – 12 September 2000) was a German geologist and coal petrologist. She specialised in the study of coal formation through petrologic analysis. In 1953, she became a founding member of the International Committee for Coal Petrology (ICCP), an organization responsible for the standardization of coal nomenclature and analytical techniques. Teichmüller was born in Herne, Westphalia, and she studied natural sciences. She went to Humboldt University in Berlin, majoring in geology in 1937, after which she went to the United States and worked with Reinhardt Thiessen at the U.S. Bureau of Mines in Pittsburgh. In 1937, she met geologist Rolf Teichmüller and married him. Thiessen died from a heart attack and she continued to examine the main question on the nature of coal under Thiessen's successor George C. Sprunk. Her doctoral thesis of 1941 under Eric Stach at Berlin was on using transmitted and reflected light for microscope studies of coal. She also studied with Walther Gothan (1879–1954). Marlies visited the US in 1963 and 1967, visiting the Everglades and other coal-forming environments that were being studied by Professor William Spackman. She concluded that it was similar to the Köln Miocene brown-coal deposits. She pioneered fluorescence microscopy in coal studies and discovered the minerals fluorinite and exudatinite. Along with her husband she examined the application of reflectance to study the extent of coal formation.

Worked examples

Example 1 — a first encounter with Marlies Teichmüller

Start with the simplest possible case. Write down what Marlies Teichmüller claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Marlies Teichmüller 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 Marlies Teichmüller 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 Marlies Teichmüller

In research: Marlies Teichmüller appears in earth science 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 Marlies Teichmüller 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: Marlies Teichmüller is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 2000 deaths, 20th-century German geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Marlies Teichmüller 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.
