Reference excerpt

Otto Linné Erdmann (11 April 1804 – 9 October 1869) was a German chemist. He was the son of Karl Gottfried Erdmann, the medical doctor who introduced vaccination into Saxony. Erdmann was born in Dresden on 11 April 1804. In 1820, he began to attend the medico-chirurgical academy of his native place. In 1822, he entered the University of Leipzig, where in 1827 he became an associate professor, and in 1830 a full professor of chemistry. This office he held until his death, which happened at Leipzig on 9 October 1869. He was particularly successful as a teacher, and the laboratory established at Leipzig under his direction in 1843 was long regarded as a model institution. As an investigator he is best known for his work on nickel and indigo and other dye-stuffs. With R. F. Marchand (1813–1850) he also carried out a number of determinations of atomic weights. In 1828, he founded the Journal für technische und ökonomische Chemie, which became in 1834 the Journal für praktische Chemie. From 1853 A. F. G. Werther (1815–1869) was an editor of the journal. Erdmann was also the author of Über das Nickel (1827), Lehrbuch der Chemie (1828), Grundriss der Waarenkunde (1833), and Über das Studium der Chemie (1861).

Worked examples

Example 1 — a first encounter with Otto Linné Erdmann

Start with the simplest possible case. Write down what Otto Linné Erdmann 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 Otto Linné Erdmann 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 Otto Linné Erdmann 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 Otto Linné Erdmann

In research: Otto Linné Erdmann 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 Otto Linné Erdmann 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: Otto Linné Erdmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1804 births, 1869 deaths, 19th-century German chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Otto Linné Erdmann 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.
