This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Per Nilsen rather than just read about it. In short: Per Nilsen (born April 8, 1960) is a Swedish professor and author. He grew up in Täby, north of Stockholm.

Key takeaways

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

Reference excerpt

Per Nilsen (born April 8, 1960) is a Swedish professor and author. He grew up in Täby, north of Stockholm. Nilsen graduated in economics at the Stockholm School of Economics in 1985. He has written substantially within the field of Implementation science as an academic and has written several music biographies, including several books focusing on David Bowie, Prince and Iggy Pop and The Stooges. In 1991, Nilsen together with Lars Einarsson created Uptown, a professionally designed international journal devoted to exploring Prince's music. They published Uptown for 12 years. The journal was praised for its insightful analysis and independence. However, in 1999 Prince and his management filed a suit against the journal, seeking to halt its publication since they could not control the content. Enlisting the help of a lawyer (longtime Uptown reader Alex Hahn), the journal successfully defended the case and the lawsuit was subsequently dropped. Nilsen studied systems development at Linköping University in 2001–2002, which led to a career as a researcher. He became a doctoral student in 2003 at the medical faculty at Linköping University and in 2006 he defended his PhD thesis on injury prevention work, whereupon he received the title of Doctor of Medicine. He became associate professor in 2008 and professor in 2014 in social medicine and public health sciences. Since 2022 he is also a professor in implementation science at Halmstad University. The scope of Nilsen's research is broad, but since 2010 has had a focus on implementation science, with issues concerning the uptake and use of research and evidence in healthcare and in society at large. In 2015, Nilsen conducted a systematic review of the theories and methods underlying the practice of implementation science; his methods were later adopted by OECD researchers seeking to apply implementation science to the field of education. He is a prolific researcher with over 200 peer-reviewed articles and several books in Swedish and English in this field. He also teaches doctoral students a course in scientific writing. Nilsen has many national and international collaborations and often speaks at conferences and courses. He has assignments for the Swedish Research Council (Vetenskapsrådet), Sweden's largest government research financier, and is a board member of the Swedish Research Council for Health, Working Life and Welfare (Forte)

Worked examples

Example 1 — a first encounter with Per Nilsen

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

In research: Per Nilsen 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 Nilsen 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 Nilsen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, Academic staff of Linköping University, Implementation scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Per Nilsen 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.
