Learn the definition first, then one example that makes the definition concrete.
Connect Volker Quaschning to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Volker Quaschning from memory before moving on to harder problems.

Reference excerpt

Volker Quaschning (born 1969) is a German engineer and professor of renewable energy systems at the Hochschule für Technik und Wirtschaft Berlin, Germany.

Life Quaschning studied electrical engineering at Karlsruhe Institute of Technology, then wrote his PhD on photovoltaics at the Technische Universität Berlin. After obtaining his habilitation on low-carbon power system scenarios for Germany, he worked for the German Aerospace Center in Almeria, Spain and lead research into concentrated solar power. In 2004, Quaschning was appointed professor of renewable energy systems at the Hochschule für Technik und Wirtschaft Berlin. Quaschning is the author of several books, including the scientific textbook Regenerative Energiesysteme (Renewable energy systems), first published in 1998. In 2015, the ninth edition of this book was released. The book has been translated in English, Arabic, and Russian and a translation to the Kazakh language is in progress. In 2016, an updated second edition in English was published.

Critisim For his political statement about the nuclear energy he was award of the prize "silbernen-Sumpfpumpe" (silver swamp pump)[1]

Worked examples

Example 1 — a first encounter with Volker Quaschning

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

In research: Volker Quaschning appears in engineering 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 Volker Quaschning 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: Volker Quaschning is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 births, 20th-century German engineers, 21st-century German engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Volker Quaschning 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.
