Per Eugen Kristiansen

Per Eugen Kristiansen 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 Per Eugen Kristiansen rather than just read about it. In short: Per Eugen Kristiansen (born 8 April 1969) is a Norwegian sailor from Bekkestua who won a bronze medal at the 2012 Summer Paralympics in the Sonar class, together with Marie Solberg and Aleksander Wang-Hansen. He has sailed since he was 7.

Key takeaways

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

Reference excerpt

Per Eugen Kristiansen (born 8 April 1969) is a Norwegian sailor from Bekkestua who won a bronze medal at the 2012 Summer Paralympics in the Sonar class, together with Marie Solberg and Aleksander Wang-Hansen. He has sailed since he was 7. In 1994, he was involved in a climbing accident, and since then has been reliant on a wheelchair. Nine months later, he was an active sailor again. In 1998, he competed for the first time after a disabled sailor invited him to an event, and from then on, he has been an active regatta sailor. In January 2012, he won the World Sailing Championship in Florida. In 1993, Kristiansen got his cand.scient. in organic chemistry from the University of Oslo. On 22 October 1999, he received his doctorate, and from 2000 to 2002, he undertook postdoctorate studies at Washington State University. From 2002 to 2005, he worked at the University of Oslo, where he is now a senior engineer in the department for biochemistry and molecular biology.

Worked examples

Example 1 — a first encounter with Per Eugen Kristiansen

Start with the simplest possible case. Write down what Per Eugen Kristiansen 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 Per Eugen Kristiansen 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 Per Eugen Kristiansen 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 Per Eugen Kristiansen

In research: Per Eugen Kristiansen 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 Per Eugen Kristiansen 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: Per Eugen Kristiansen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 births, 2012 Summer Paralympics stubs, 20th-century Norwegian sportsmen, so understanding it makes those chapters shorter.
In everyday life: Look for Per Eugen Kristiansen 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.
