Reference excerpt

This list of isthmuses is an appendix to the article isthmus. The list is sorted by the region of the world in which the isthmus is located. An isthmus ( or ; plural: isthmuses, or occasionally isthmi; from Ancient Greek: ἰσθμός, romanized: isthmos, lit. 'neck') is a narrow piece of land connecting two larger areas across an expanse of water that otherwise separates them. A tombolo is an isthmus that consists of a spit or bar.

Worked examples

Example 1 — a first encounter with List of isthmuses

Start with the simplest possible case. Write down what List of isthmuses 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 List of isthmuses 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 List of isthmuses 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 List of isthmuses

In research: List of isthmuses 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 List of isthmuses 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: List of isthmuses is common in secondary-school and first-year university syllabi. It links to neighbouring topics Isthmuses, Lists of landforms, so understanding it makes those chapters shorter.
In everyday life: Look for List of isthmuses 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.
