Georg Wiegner

Georg Wiegner is a chemistry 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 Georg Wiegner rather than just read about it. In short: Georg Wiegner (April 20, 1883 – April 14, 1936) was a colloid chemist. He was born in Leipzig and died in Zurich.

Key takeaways

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

Reference excerpt

Georg Wiegner (April 20, 1883 – April 14, 1936) was a colloid chemist. He was born in Leipzig and died in Zurich. Georg Wiegner studied natural sciences at the University of Leipzig, and received a doctorate in 1906. He was an assistant to Wilhelm Fleischmann at the University of Göttingen from 1907. He was appointed professor of agricultural chemistry at the ETH Zurich in 1913, where he remained until the year of his death, in 1933. He was responsible for seminal discoveries in coagulation and ion exchange. His group at the ETH strongly influenced ecological pedology in Switzerland. The group who worked with him included Hermann Gessner (1897–1981), Hans Jenny (1899–1992) and Hans Pallmann (1903–1965). His group also influenced the work of Max Düggeli, who had a major influence on soil biology in Switzerland.

Worked examples

Example 1 — a first encounter with Georg Wiegner

Start with the simplest possible case. Write down what Georg Wiegner 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 Georg Wiegner 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 Georg Wiegner 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 Georg Wiegner

In research: Georg Wiegner 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 Georg Wiegner 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: Georg Wiegner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1883 births, 1936 deaths, 20th-century German chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Georg Wiegner 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.

Frequently asked questions

What is Georg Wiegner in simple terms?

Georg Wiegner (April 20, 1883 – April 14, 1936) was a colloid chemist. He was born in Leipzig and died in Zurich.

Why does Georg Wiegner matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Georg Wiegner?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
