Per Olof Hulth

Per Olof Hulth is a physics 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 Olof Hulth rather than just read about it. In short: Per Olof Hulth (2 June 1943 – 26 February 2015) was a Swedish astroparticle physicist. Hulth grew up in Stockholm.

Key takeaways

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

Reference excerpt

Per Olof Hulth (2 June 1943 – 26 February 2015) was a Swedish astroparticle physicist. Hulth grew up in Stockholm. He graduated with a PhD degree in particle physics in 1976 from Stockholm University, the same university where he later for many years was Professor of Experimental Astroparticle Physics and in the late 1990s headed the Department of Physics. Hulth also worked at CERN in Geneva and was one of the key European participants in the AMANDA project at the South Pole, as well as its successor experiment IceCube, designed to study neutrinos from space in the polar cap ice. He was spokesperson of the IceCube collaboration from 2001 to 2005. Hulth became a member of the Class for Physics of the Royal Swedish Academy of Sciences in 2004. He was chairman of the Education Committee of the Royal Academy and a prominent critic of for-profit independent primary and secondary schools, calling for a national ban on for-profit schools in Sweden in 2013. He was an active member of Föreningen Vetenskap och Folkbildning, The Swedish Skeptics' Association, and served as its chairman from 1988 to 1998. Per Olof Hulth was older brother to Mats Hulth, social democratic politician and former Commissioner of Finance of Stockholm Municipality.

Worked examples

Example 1 — a first encounter with Per Olof Hulth

Start with the simplest possible case. Write down what Per Olof Hulth claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Olof Hulth 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 Olof Hulth 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 Olof Hulth

In research: Per Olof Hulth appears in physics 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 Olof Hulth 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 Olof Hulth is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 2015 deaths, Academic staff of Stockholm University, so understanding it makes those chapters shorter.
In everyday life: Look for Per Olof Hulth 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.
