Key takeaways

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

Reference excerpt

Marjo-Riitta Järvelin (born 21 March 1954 in Sysmä, Finland) is a Finnish epidemiologist. Since 2002 she has been professor of lifecourse epidemiology at Imperial College London. She is also part-time professor of public health at the University of Oulu, Finland, and visiting faculty at London's Brunel University. Järvelin studied at the University of Oulu, receiving her medical degree in 1980 and a Ph.D. in epidemiology in 1989. She qualified as a pediatric specialist in 1987. She has a master's degree from the University of London Environmental Epidemiology and Policy (1994) and became a licensed physician in the UK in 1998. For more than 25 years Järvelin has conducted public health research based on large populations from northern Finland. Two major resources are the NFBC1966 and NFBC1986 birth cohorts from Northern Finland, which were collected during the years 1965 and 1985 from women attending prenatal examinations. Järvelin has been the scientific director of these birth cohorts for several years. A long follow-up period has enabled a fully-fledged epidemiological programme throughout the life span. Järvelin has studied, among other things, the effects of genetic and early environmental factors on the emergence of multifactorial diseases. She also coordinated the international DynaHEALTH research project (a Horizon 2020 project) focusing on supporting healthier and more active aging and reducing type II diabetes and obesity. Among the international acknowledgments that she has received for her scientific work, Professor Järvelin was named Finland's Epidemiologist of the Year in 2012. She has been a member of the Finnish Academy of Sciences since 2013.

Worked examples

Example 1 — a first encounter with Marjo-Riitta Järvelin

Start with the simplest possible case. Write down what Marjo-Riitta Järvelin 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 Marjo-Riitta Järvelin 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 Marjo-Riitta Järvelin 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 Marjo-Riitta Järvelin

In research
Marjo-Riitta Järvelin 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 Marjo-Riitta Järvelin 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
Marjo-Riitta Järvelin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 births, 20th-century Finnish scientists, 20th-century women scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Marjo-Riitta Järvelin 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.
