Otto Schneider-Orelli is a astronomy 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 Otto Schneider-Orelli rather than just read about it. In short: Otto Schneider-Orelli (10 August 1880 in Münchenbuchsee – 31 October 1965 in Zürich) was a Swiss entomologist. He studied natural sciences at the universities of Neuchâtel (1899) and Bern (1900–05).

Key takeaways

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

Reference excerpt

Otto Schneider-Orelli (10 August 1880 in Münchenbuchsee – 31 October 1965 in Zürich) was a Swiss entomologist. He studied natural sciences at the universities of Neuchâtel (1899) and Bern (1900–05). Following graduation, he worked as an assistant under Hermann Müller-Thurgau at the research institute for arboriculture, horticulture and viticulture in Wädenswil, where from 1913, he worked as an entomologist. From 1928 to 1950 he served as an associate professor of entomology at ETH Zurich and as director of the Institute of Entomology. From 1917 onward, he was curator of collections at the entomology museum of ETH Zurich. He specialized in the fields of agricultural and forest entomology. He was the author of many treatises on phylloxera.

Selected works Reblausversuche im Kanton Zürich, 1921 – Essay on phylloxera concerning the canton of Zürich. Die Reblaus und unser Weinbau, 1923 – Phylloxera and viticulture. Vergleichende Untersuchungen zur Reblausfrage (with Hans Leuzinger), 1924 – Comparative studies on phylloxera. Schädlingsbüchlein für Landwirtschaft, Garten, Haus und Hof, 1938 – "Pest booklet" for farming, gardening, home and yard. Entomologisches Praktikum; Einführung in die land- und forstwirtschaftliche Insektenkunde, 1947 – Entomological internship; introduction to agricultural and forest entomology.

Worked examples

Example 1 — a first encounter with Otto Schneider-Orelli

Start with the simplest possible case. Write down what Otto Schneider-Orelli claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Schneider-Orelli 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 Schneider-Orelli 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 Schneider-Orelli

In research: Otto Schneider-Orelli appears in astronomy 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 Schneider-Orelli 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 Schneider-Orelli is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1880 births, 1965 deaths, 20th-century Swiss zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Otto Schneider-Orelli 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.
