Reference excerpt

Louis Charles Émile Lortet (22 August 1836 – 26 December 1909) was a French physician, botanist, zoologist and Egyptologist who was a native of Oullins. He earned his medical doctorate in 1861, and his degree in natural sciences in 1867. He served as premier doyen at the Faculty of Medicine of Lyon from 1877 until 1906. Also, from 1868 to 1909, he was director of the natural history museum in Lyon. Lortet is remembered for his scientific and zoological expeditions to the Middle East (Syria, Lebanon and Egypt). He performed studies of mummified animals from the New Kingdom of ancient Egypt, and in 1880 took part in an excavation of a Phoenician necropolis. Lortet was a member of numerous scientific societies, such as the Société de géographie de Lyon, being a founding member in 1858. Species with the epithet of lorteti are named in his honor; an example being the pufferfish species Carinotetraodon lorteti.

Worked examples

Example 1 — a first encounter with Louis Charles Émile Lortet

Start with the simplest possible case. Write down what Louis Charles Émile Lortet 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 Louis Charles Émile Lortet 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 Louis Charles Émile Lortet 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 Louis Charles Émile Lortet

In research: Louis Charles Émile Lortet 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 Louis Charles Émile Lortet 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: Louis Charles Émile Lortet is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1836 births, 1909 deaths, Academic staff of the University of Lyon, so understanding it makes those chapters shorter.
In everyday life: Look for Louis Charles Émile Lortet 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.
