This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Paul Wilhelm Magnus rather than just read about it. In short: Paul Wilhelm Magnus (29 February 1844 – 13 March 1914) was a German botanist and mycologist. Magnus was born in Berlin.

Key takeaways

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

Reference excerpt

Paul Wilhelm Magnus (29 February 1844 – 13 March 1914) was a German botanist and mycologist. Magnus was born in Berlin. He studied natural sciences at the Universities of Berlin and Freiburg. As a student of Alexander Braun at Berlin, he obtained his PhD in 1870 with a thesis on the aquatic plant genus Najas. In 1875, he became privat-docent at Berlin, where beginning in 1880, he served as an assistant professor of botany. From 1871 to 1874, as a botanist aboard the vessel Pomerania, he conducted investigations of algae found in the North and Baltic Seas as well as in the Schlei estuary. In 1893 he was instrumental in the founding of the Biologische und Fischereistation Müggelsee (presently serving as a measuring station for the Leibniz-Institut für Gewässerökologie und Binnenfischerei). During his career, he analyzed material collected by other botanists, including specimens collected by Joseph Friedrich Nicolaus Bornmüller (Turkey and Syria), Georg Schweinfurth (Eritrea) and Rudolf Marloth (South Africa). He died in Berlin, aged 70. Nearly half of his more than 600 works concerned mycological topics, and he is remembered for his investigations of the parasitic fungi families Ustilaginaceae and Uredinaceae. He was responsible for "Die Pilze (Fungi) von Tirol, Vorarlberg und Liechtenstein", an 810-page monograph on fungi that was Volume 3 of Dalla Torre and Sarnthein's series on the flora of Tyrol, Vorarlberg and Liechtenstein.

Selected writings Erstes Verzeichniss der ihm aus dem Kanton Graubünden bekannt gewordenen Pilze, 1890. Unsere Kenntnis unterirdisch lebender streng parasitischer Pilze und die biologische Bedeutung eines solchen unterirdischen Parasitismus, 1892. Vierter Beitrag zur Pilzflora von Franken, 1906.

Worked examples

Example 1 — a first encounter with Paul Wilhelm Magnus

Start with the simplest possible case. Write down what Paul Wilhelm Magnus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Paul Wilhelm Magnus 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 Paul Wilhelm Magnus 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 Paul Wilhelm Magnus

In research: Paul Wilhelm Magnus appears in biology 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 Paul Wilhelm Magnus 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: Paul Wilhelm Magnus is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1844 births, 1914 deaths, 19th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Paul Wilhelm Magnus 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.
