Reference excerpt

Juerg Leuthold is a full professor at ETH Zurich, Switzerland.

Biography Leuthold was born in 1966 in Switzerland. He received a Ph.D. degree in physics from ETH Zurich for work in the field of integrated optics and all-optical communications. From 1999 to 2004 Leuthold was affiliated with Bell Labs, Lucent Technologies in Holmdel, USA, where he performed device and system research with III/V semiconductor and silicon optical bench materials for applications in high-speed telecommunications. From 2004 to 2013 Leuthold was a full professor at Karlsruhe Institute of Technology, where he headed the Institute of Photonics and Quantum Electronics and the Helmholtz Institute of Microtechnology. Since March 2013 he has been a full professor at ETH Zurich, where he heads the Institute of Electromagnetic Fields.

Affiliations Leuthold is a fellow of the Optical Society of America and of the Institute of Electrical and Electronics Engineers. When he was a professor at Karlsruhe, he was a member of the Helmholtz Association Think Tank and a member of the Heidelberg Academy of Science. He served on the board of directors of the Optical Society of America. Leuthold has been and is serving the community as general chair and in many technical program committees.

Worked examples

Example 1 — a first encounter with Juerg Leuthold

Start with the simplest possible case. Write down what Juerg Leuthold 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 Juerg Leuthold 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 Juerg Leuthold 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 Juerg Leuthold

In research: Juerg Leuthold 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 Juerg Leuthold 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: Juerg Leuthold is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, 20th-century Swiss physicists, 21st-century Swiss physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Juerg Leuthold 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.
