Harold Cogger

Harold Cogger is a biology 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 Harold Cogger rather than just read about it. In short: Harold George "Hal" Cogger (born 4 May 1935) is an Australian herpetologist. He was curator of reptiles and amphibians at the Australian Museum from 1960 to 1975, and Deputy Director of the museum from 1976 to 1995.

Key takeaways

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

Reference excerpt

Harold George "Hal" Cogger (born 4 May 1935) is an Australian herpetologist. He was curator of reptiles and amphibians at the Australian Museum from 1960 to 1975, and Deputy Director of the museum from 1976 to 1995. He has written extensively on Australian herpetology, and was the first author to create a field guide for all Australian frogs and reptiles. Cogger was made an honorary Doctor of Science in 1997. At least eight reptile taxa have been named after Cogger, including one genus, six species, and one subspecies: Coggeria, Ctenotus coggeri, Emoia coggeri, Geomyersia coggeri, Hydrophis coggeri, Lampropholis coggeri, Oedura coggeri, and Diporiphora nobbi coggeri.

Worked examples

Example 1 — a first encounter with Harold Cogger

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

In research: Harold Cogger appears in biology 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 Harold Cogger 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: Harold Cogger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1935 births, Australian biologist stubs, Australian herpetologists, so understanding it makes those chapters shorter.
In everyday life: Look for Harold Cogger 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.
