Georg Frederik Ursin

Georg Frederik Ursin is a mathematics 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 Frederik Ursin rather than just read about it. In short: Georg Frederik Krüger Ursin (22 June 1797 – 4 December 1849) was a Danish mathematician and astronomer. Early life His father, Georg Jacob Krüger, was a first lieutenant in the Royal Danish Navy, however, in 1798, his was stripped of his functions where was taken to Munkholmen, an islet north of Trondheim, Norway.

Key takeaways

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

Reference excerpt

Georg Frederik Krüger Ursin (22 June 1797 – 4 December 1849) was a Danish mathematician and astronomer.

Early life His father, Georg Jacob Krüger, was a first lieutenant in the Royal Danish Navy, however, in 1798, his was stripped of his functions where was taken to Munkholmen, an islet north of Trondheim, Norway. In the same year, Ursin was given royal license to carry the maternal family name from his mother, Jacobine Ursin (1772–1819), daughter of rear admiral Ursin, married to a wealthy shipbuilder and shipyard owner Lars Larsen.

Education In 1814, Ursin passed an exam in land surveying before graduating cum laude from Metropolitanskolen in 1815. Having won a prize assignment involving regular polyhedron, he passed a second exam cum laude.

Death and legacy Ursin died on December 4, 1849, in Copenhagen. A DSB Class EA locomotive no. 3020 is named after Ursin.

Worked examples

Example 1 — a first encounter with Georg Frederik Ursin

Start with the simplest possible case. Write down what Georg Frederik Ursin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Frederik Ursin 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 Frederik Ursin 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 Frederik Ursin

In research: Georg Frederik Ursin appears in mathematics 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 Frederik Ursin 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 Frederik Ursin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1797 births, 1849 deaths, Danish mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Georg Frederik Ursin 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.
