Per Maltby

Per Maltby 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 Maltby rather than just read about it. In short: Per Maltby (3 November 1933 – 24 May 2006) was a Norwegian astronomer. He took his cand.real. degree at the University of Oslo in 1957, and was a research assistant there before becoming lecuter at the University of Bergen in 1960.

Key takeaways

Per Maltby 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 Maltby to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Per Maltby from memory before moving on to harder problems.

Reference excerpt

Per Maltby (3 November 1933 – 24 May 2006) was a Norwegian astronomer. He took his cand.real. degree at the University of Oslo in 1957, and was a research assistant there before becoming lecuter at the University of Bergen in 1960. His specialties were solar physics and radioastronomy. He took the dr.philos. degree in 1964, was appointed as a lecturer of astrophysics at the University of Oslo in 1967, and was a professor from 1983. He published several books, including textbooks. At his death he was called "the most important pillar of Norwegian astrophysics and space research over the last 40 years".

Worked examples

Example 1 — a first encounter with Per Maltby

Start with the simplest possible case. Write down what Per Maltby 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 Maltby 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 Maltby 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 Maltby

In research: Per Maltby 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 Maltby 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 Maltby is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 births, 2006 deaths, Academic staff of the University of Bergen, so understanding it makes those chapters shorter.
In everyday life: Look for Per Maltby 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.
