Otto Maass

Otto Maass 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 Maass rather than just read about it. In short: Otto Maass, (8 July 1890 – 3 July 1961) was a Canadian academic and scientist. Education Born in New York City, New York, Maass started teaching at McGill University in 1923 retiring in 1955.

Key takeaways

Otto Maass 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 Maass to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Otto Maass from memory before moving on to harder problems.

Reference excerpt

Otto Maass, (8 July 1890 – 3 July 1961) was a Canadian academic and scientist.

Education Born in New York City, New York, Maass started teaching at McGill University in 1923 retiring in 1955. He was the Macdonald Professor of Chemistry and was chairman of the department of chemistry from 1937 to 1955.

Career His scientific research in physical chemistry included contributions in calorimetry, critical-state phenomena, preparation and properties of pure hydrogen peroxide, properties of cellulose, and the chemical pulping of wood. In 1940, he was made a Fellow of the Royal Society. In 1946, he was made a Commander of the Order of the British Empire. In 1947, he was named the director of the newly created DRB biological and chemical warfare research division. A Fellow of the Royal Society of Canada, he was awarded the Society's Henry Marshall Tory Medal in 1945. McGill University's Otto Maass Chemistry Building, built between 1964 and 1966, is named in his honour. To this day there remains a plaque on the building dedicating it to Maass's excellent contributions to "science in defense of his country", widely interpreted as a euphemistic nod to his work on Fuel Air Explosives.

Worked examples

Example 1 — a first encounter with Otto Maass

Start with the simplest possible case. Write down what Otto Maass 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 Maass 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 Maass 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 Maass

In research: Otto Maass 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 Maass 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 Maass is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890 births, 1961 deaths, Academic staff of McGill University, so understanding it makes those chapters shorter.
In everyday life: Look for Otto Maass 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.
