Mauri Valtonen

Mauri Valtonen 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 Mauri Valtonen rather than just read about it. In short: Mauri Valtonen (born 1945) is a Finnish astronomer and professor at the University of Turku. His fields of scientific interest include active galaxies, cosmology, and the three-body problem.

Key takeaways

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

Reference excerpt

Mauri Valtonen (born 1945) is a Finnish astronomer and professor at the University of Turku. His fields of scientific interest include active galaxies, cosmology, and the three-body problem. Valtonen completed a Ph.D. from Cambridge University in 1975. He served as Director of Tuorla Observatory from 1980 to 2002 and returned to this position again in 2007.

In 2008, Valtonen led a research team which argued that delay in the periodic outbursts from the nucleus of the active galaxy OJ 287 confirmed Albert Einstein's general theory of relativity.

Worked examples

Example 1 — a first encounter with Mauri Valtonen

Start with the simplest possible case. Write down what Mauri Valtonen 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 Mauri Valtonen 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 Mauri Valtonen 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 Mauri Valtonen

In research: Mauri Valtonen 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 Mauri Valtonen 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: Mauri Valtonen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, 21st-century astronomers, Finnish astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Mauri Valtonen 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.
