Richard Kräusel

Richard Kräusel 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 Richard Kräusel rather than just read about it. In short: Richard Oswald Karl Kräusel (29 August 1890 in Breslau – 25 November 1966 in Frankfurt am Main) was a German paleobotanist. He studied botany at the University of Breslau as a pupil of Ferdinand Albin Pax, and in 1913 received his doctorate with the thesis Beiträge zur kenntnis der Holzer aus der schlesischen Braunkohle ("On wood from Silesian lignite").

Key takeaways

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

Reference excerpt

Richard Oswald Karl Kräusel (29 August 1890 in Breslau – 25 November 1966 in Frankfurt am Main) was a German paleobotanist. He studied botany at the University of Breslau as a pupil of Ferdinand Albin Pax, and in 1913 received his doctorate with the thesis Beiträge zur kenntnis der Holzer aus der schlesischen Braunkohle ("On wood from Silesian lignite"). From 1920 to 1952 he worked as a lecturer and professor at the University of Frankfurt. He was also associated with the Senckenberg Natural History Museum in Frankfurt, where he served as head of the department of paleobotany. During World War II his collections of fossil plants were stored in a nearby castle for safekeeping; unfortunately these collections were destroyed during bombing raids on Frankfurt. During his career, he traveled worldwide in his investigations of fossil plants — Southeast Asia (1921, 1926), South America (1924, 1947, 1956/57), United States and Canada (1928, 1959), South-West Africa (1928, 1953–54) and India (1960/61, 1964). On his later journeys, he conducted research on flora of Gondwanaland and collected fossil specimens to replace those that were previously destroyed. In Europe, he carried out studies of Mesozoic flora of southern Germany, Austria and Switzerland. With Hermann Weyland, he carried out important research on land plants of the Devonian. He is also remembered for his analysis of Tertiary angiosperm leaf cuticles.

Worked examples

Example 1 — a first encounter with Richard Kräusel

Start with the simplest possible case. Write down what Richard Kräusel 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 Richard Kräusel 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 Richard Kräusel 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 Richard Kräusel

In research: Richard Kräusel 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 Richard Kräusel 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: Richard Kräusel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890 births, 1966 deaths, 20th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Kräusel 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.
