Georg Wilhelm Freyreiss

Georg Wilhelm Freyreiss 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 Georg Wilhelm Freyreiss rather than just read about it. In short: Georg Wilhelm Freyreiss (12 July 1789, in Frankfurt am Main – 1 April 1825, in Nova Viçosa) was a German naturalist. As an assistant naturalist, he traveled to Rio de Janeiro in 1813 with Grigory Langsdorff, the newly appointed Russian consul to Brazil.

Reference excerpt

Georg Wilhelm Freyreiss (12 July 1789, in Frankfurt am Main – 1 April 1825, in Nova Viçosa) was a German naturalist. As an assistant naturalist, he traveled to Rio de Janeiro in 1813 with Grigory Langsdorff, the newly appointed Russian consul to Brazil. Here, he met with Lorentz Westin (1787–1846), the Swedish-Norwegian general consul, who provided the necessary means for Freyreiss to travel and explore the country's interior. With geologist Wilhelm Ludwig von Eschwege, he visited various locations in Minas Gerais, during which, he collected numerous ornithological, entomological and botanical specimens. From August 1815, along with Friedrich Sellow and Prince Maximilian of Wied-Neuwied, he collected natural history specimens in the province of Bahia for several European institutions. In 1818 he was named a professor of zoology at the University of Rio de Janeiro. In 1824 he published Beiträge zur näheren Kenntniss des Kaiserthums Brasilien ("Contributions to the knowledge of the empire of Brazil"). Another work attributed to Freyreiss is Reisen in Brasilien (1968), a book on Brazil that was published many years after his death. Taxa with the specific epithet of freyreissii honor his name, examples being the botanical species Ophryosporus freyreissii and Paepalanthus freyreissii.

Worked examples

Example 1 — a first encounter with Georg Wilhelm Freyreiss

Start with the simplest possible case. Write down what Georg Wilhelm Freyreiss 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 Georg Wilhelm Freyreiss 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 Georg Wilhelm Freyreiss 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 Georg Wilhelm Freyreiss

In research: Georg Wilhelm Freyreiss 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 Georg Wilhelm Freyreiss 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: Georg Wilhelm Freyreiss is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1789 births, 1825 deaths, 19th-century German naturalists, so understanding it makes those chapters shorter.
In everyday life: Look for Georg Wilhelm Freyreiss 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.
