Reproduce the core statement of Rainer Waser from memory before moving on to harder problems.

Reference excerpt

Rainer Waser (born 16 September 1955, in Frankfurt) is a German professor of Electrical Engineering at RWTH Aachen University. He is also director of the section Electronic Materials at the Peter Grünberg Institute which is located on the campus of Jülich Research Center (Forschungszentrum Jülich). His research and teaching is on solid-state chemistry and defect chemistry to electronic properties and modelling, the technology of new materials and the physical properties of construction components. Important findings include insights in the functioning of the so-called memristors. Waser grew up in Heusenstamm near Frankfurt. He studied Physical Chemistry at Darmstadt University of Technology where he received a diploma degree in 1979. Then he went to the University of Southampton to conduct research at the Institute of Electrochemistry. After that he turned to Darmstadt and worked as scientific assistant until he completed his PhD.

Career Waser joined the Philips research laboratories (research group Electronic Ceramics) at Aachen. In 1992, Waser accepted a Chair for Electronic Materials in the Faculty of Electrical Science and Information Technology at RWTH Aachen University. In 2012, Waser was elected to the post of Speaker of the Department of Electrical Engineering and Information Technology at Aachen university. Waser was awarded the renowned Gottfried Wilhelm Leibniz Prize in 2014.

Worked examples

Example 1 — a first encounter with Rainer Waser

Start with the simplest possible case. Write down what Rainer Waser claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Rainer Waser 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 Rainer Waser 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 Rainer Waser

In research: Rainer Waser appears in chemistry 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 Rainer Waser 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: Rainer Waser is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, Academic staff of RWTH Aachen University, Engineers from Frankfurt, so understanding it makes those chapters shorter.
In everyday life: Look for Rainer Waser 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.
