Professor Challenger

Professor Challenger 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 Professor Challenger rather than just read about it. In short: George Edward Challenger is a fictional character in a series of fantasy and science fiction stories by Sir Arthur Conan Doyle. Unlike Doyle's self-controlled, analytical character, Sherlock Holmes, Professor Challenger is an aggressive but virtuous figure.

Key takeaways

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

Reference excerpt

George Edward Challenger is a fictional character in a series of fantasy and science fiction stories by Sir Arthur Conan Doyle. Unlike Doyle's self-controlled, analytical character, Sherlock Holmes, Professor Challenger is an aggressive but virtuous figure. Like Sherlock Holmes, Professor Challenger was based on a real person—in this case, two people: an explorer, Percy Fawcett, who was Doyle's friend; and a professor of physiology named William Rutherford, who had lectured at the University of Edinburgh while Conan Doyle studied medicine there. Professor Challenger first appeared in the novel The Lost World (1912) by Arthur Conan Doyle.

Fictional character biography George Edward Challenger, FRS, MD, DSc, is born in Largs, Ayrshire in 1863 and educated at Largs Academy before studying at the University of Edinburgh. Dr Challenger is appointed to an assistant position at the British Museum in 1892 and is promoted within a year to assistant keeper in the Comparative Anthropology Department. He holds a professorship in Zoology and is elected President of the Zoological Institute in London. Several of his inventions are successfully applied in industry and bring him additional income. Edward Malone, the narrator of The Lost World, the 1912 novel in which Challenger first appears, describes his first meeting with the character:

Worked examples

Example 1 — a first encounter with Professor Challenger

Start with the simplest possible case. Write down what Professor Challenger 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 Professor Challenger 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 Professor Challenger 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 Professor Challenger

In research: Professor Challenger 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 Professor Challenger 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: Professor Challenger is common in secondary-school and first-year university syllabi. It links to neighbouring topics Book series, Characters in written science fiction, Fantasy book series, so understanding it makes those chapters shorter.
In everyday life: Look for Professor Challenger 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.
