Marie Lemoine

Marie Lemoine is a science 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 Marie Lemoine rather than just read about it. In short: Marie Dujardin Beaumetz Lemoine (French pronunciation: [maʁi dyʒaʁdɛ̃ bome ləmwan]; 1887–1984) was a French botanist and phycologist noted for her study of the algae Corallinales and her work at the National Museum of Natural History (France). She married French geologist Paul Lemoine.

Key takeaways

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

Reference excerpt

Marie Dujardin Beaumetz Lemoine (French pronunciation: [maʁi dyʒaʁdɛ̃ bome ləmwan]; 1887–1984) was a French botanist and phycologist noted for her study of the algae Corallinales and her work at the National Museum of Natural History (France). She married French geologist Paul Lemoine. The standard author abbreviation Me.Lemoine is used to indicate this person as the author when citing a botanical name.

Worked examples

Example 1 — a first encounter with Marie Lemoine

Start with the simplest possible case. Write down what Marie Lemoine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Marie Lemoine 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 Marie Lemoine 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 Marie Lemoine

In research: Marie Lemoine appears in science 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 Marie Lemoine 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: Marie Lemoine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1887 births, 1984 deaths, 20th-century French botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Marie Lemoine 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.
