Jacques Lewiner

Jacques Lewiner 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 Jacques Lewiner rather than just read about it. In short: Jacques Lewiner (born in 1943) is a French physicist and inventor. He is professor and Honorary Scientific Director of École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI Paris), and (since 2012) dean of innovation and entrepreneurship at PSL Research University.

Key takeaways

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

Reference excerpt

Jacques Lewiner (born in 1943) is a French physicist and inventor. He is professor and Honorary Scientific Director of École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI Paris), and (since 2012) dean of innovation and entrepreneurship at PSL Research University. Jacques Lewiner has carried out basic and applied research in various domains of physics. Following his PhD, he taught at Catholic University of America and specialized in the study of the electrical properties of solid matter. Back in France he was nominated Professor in charge of the Electromagnetism Chair at ESPCI Paris where Georges Charpak arrived in 1980. From 1987 to 2001 he was directeur d'études at ESPCI Paris under the direction of Pierre-Gilles de Gennes. Lewiner's works have been devoted to electrical insulators and particularly electrets, instrumentation and sensors, for instance in medical imaging, or on the improvement of telecommunication networks. Jacques Lewiner has filed a large number of patent applications leading to industrial development, either through licenses granted to industrial companies or through start-up companies often created with former students or researchers. He has participated in the creation of various technology oriented start up companies, for instance Inventel, specializing in Telecommunications, Finsécur which develops and markets fire detection systems, Sculpteo which is an online 3D printing platform, Roowin in the field of chemical synthesis and Cynove in embedded electronics devices. Most of these companies have experienced a strong growth. For instance Inventel, which was the French leader for multimedia gateways was bought by Thomson SA in 2005. With Jean-Louis Viovy he created Fluigent which develops fluid motion systems for micro-fluidic applications. Jacques Lewiner is laureate of the French Academy of Sciences in 1990, Knight in the National Order of the Legion of Honor, member of the French Academy of Technologies since 2005, Honorary Fellow of the Technion, Doctor Honoris Causa from Ben Gurion University of the Negev, Doctor Honoris Causa from Technion. In 2017 he has received the Marius Lavet Special Prize. In 1968 he married Colette de Botton (who received her doctorate in physics in 1973 and has won several awards). They have three children. In 2005 Jacques and Colette Lewiner gave a large endowment to the Technion's Institute for Theoretical Physics, and in June 2006 a naming ceremony established the Lewiner Institute for Theoretical Physics.

Worked examples

Example 1 — a first encounter with Jacques Lewiner

Start with the simplest possible case. Write down what Jacques Lewiner 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 Jacques Lewiner 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 Jacques Lewiner 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 Jacques Lewiner

In research: Jacques Lewiner 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 Jacques Lewiner 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: Jacques Lewiner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, Academic staff of ESPCI Paris, Catholic University of America faculty, so understanding it makes those chapters shorter.
In everyday life: Look for Jacques Lewiner 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.
