Reference excerpt

The International Convention on the Control of Harmful Anti-fouling Systems in Ships (AFS Convention) is a 2001 International Maritime Organization (IMO) treaty whereby states agree to prohibit the use of harmful anti-fouling paints and other anti-fouling systems that contain harmful substances. In particular, the use of the organotin tributyltin is prohibited, since leaching of that chemical from the hulls of ships has been shown to cause deformations in oysters and sex changes in whelks. The convention was concluded in London on 5 October 2001 and entered into force on 17 September 2008. As of November 2018, it has been ratified by 81 states, which includes 79 United Nations member states plus the Cook Islands and Niue. A ratifying state agrees to enforce the prohibitions of the convention on all ships flying its flag and on any ship that enters a port, shipyard, or offshore terminal of the state. The 81 ratifying states represent approximately 94 per cent of the gross tonnage of the world's merchant fleets.

Worked examples

Example 1 — a first encounter with International Convention on the Control of Harmful Anti-fouling Systems on Ships

Start with the simplest possible case. Write down what International Convention on the Control of Harmful Anti-fouling Systems on Ships claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 International Convention on the Control of Harmful Anti-fouling Systems on Ships 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 International Convention on the Control of Harmful Anti-fouling Systems on Ships 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 International Convention on the Control of Harmful Anti-fouling Systems on Ships

In research: International Convention on the Control of Harmful Anti-fouling Systems on Ships appears in physics 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 International Convention on the Control of Harmful Anti-fouling Systems on Ships 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: International Convention on the Control of Harmful Anti-fouling Systems on Ships is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2001 in London, 2001 in the environment, Environmental treaties, so understanding it makes those chapters shorter.
In everyday life: Look for International Convention on the Control of Harmful Anti-fouling Systems on Ships 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.
