Key takeaways

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

Reference excerpt

Gerold Rahmann (born 29 April 1962 in Wittmund, Germany) is a German agricultural economist.

Rahmann was born on a small dairy farm in East Frisia, Germany. After highschool and civil service he studied agricultural economy at the University of Göttingen, Germany. From 1990 to 1993 he was scientist in the interdisciplinary project "Animal Husbandry in the Sahel - Recent situation and development. In 1993, he made his PhD in socioeconomics at the same university in the Institute of Rural Development. 1993 he moved to a post-doc position to the University of Kassel, the faculty of Organic Agricultural Research, and focused his work in the "Biotope management with Livestock in Europe. In 1999 he did his habilitation in this area at the University of Kassel, Germany. Since 2006 he is professor at the same faculty. In 2000, Rahmann became founding director of the Federal Institute of Organic Farming at the German Federal Agricultural Research Centre (FAL). In 2007, the German federal agricultural research was reorganized and the FAL terminated. The Institute of Organic Farming was launched to the Research Centre of Rural Areas, Forestry and Fishery - the Thuenen-Institute - under the umbrella of the German Ministry of Nutrition and Agriculture (BMEL). From 2015 to 2017, Rahmann took a long term leave to establish the Green Innovation Centre in Ethiopia, as part of the Special Initiative One World no Hunger, as global programme of the German Ministry of Economic Cooperation and Development (BMZ). Besides the main job duties, Rahmann was voluntarily active in national and international organizations, mainly in the area of organic farming. 2014-2017 he was president of the International Society of Organic Farming Research (ISOFAR) and World Board of the International Federation of Organic Agricultural Movements (IFOAM). Since 2014, Rahmann is editor-in-chief of the scientific Journal of Organic Agriculture. He is associated editor of the scientific Journal of Applied Agriculture and Forestry Research. In 1986, Rahmann became member of the German Green party and active in the counties of Göttingen (1989–2000) and Stormarn (2003–2018).

Worked examples

Example 1 — a first encounter with Gerold Rahmann

Start with the simplest possible case. Write down what Gerold Rahmann 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 Gerold Rahmann 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 Gerold Rahmann 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 Gerold Rahmann

In research: Gerold Rahmann 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 Gerold Rahmann 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: Gerold Rahmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, Agricultural economists, German economists, so understanding it makes those chapters shorter.
In everyday life: Look for Gerold Rahmann 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.
