Reference excerpt

London Calling (later renamed BBC Worldwide, then BBC On Air) is a former monthly magazine that contained programme listings for the BBC World Service shortwave radio broadcasting service. Originally called the Empire Programme Pamphlet (for what was then known as the BBC Empire Service) and then BBC Empire Broadcasting, the title was changed to London Calling in mid-1939 when the magazine expanded from 12 pages to 16. The title alludes to the BBC World Service's station identification: "This is London calling ...", which was used during World War II, often in broadcasts to occupied countries.

Background In November 1993, the magazine was replaced with a 100-page colour magazine (up until then, the magazine was printed in two colours except for the front and back covers) and started including more and deeper stories, and renamed BBC Worldwide (from April to November 1995, there was a North American edition, subtitled BBC Worldwide North America, presumably so the magazine could be sent to North American subscribers and appear on shelves in North American stores without the cost of having to send the issues air mail from the UK each month). However, rising costs, which forced the BBC to reduce the size of the paper it used at one point, caused the magazine to change back to a mainly-listings format, and the title was changed to BBC On Air (later stylised BBC on|air), although the longer stories would make their way back into the magazine over the years. The last edition of BBC On Air was that of December 2004. In a letter sent to subscribers the managing director of the magazine cited as reason for the discontinuation "that many of our listeners are getting programme information on line and that it is no longer cost-effective to produce the printed edition of the magazine."

Worked examples

Example 1 — a first encounter with London Calling (magazine)

Start with the simplest possible case. Write down what London Calling (magazine) 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 London Calling (magazine) 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 London Calling (magazine) 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 London Calling (magazine)

In research: London Calling (magazine) 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 London Calling (magazine) 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: London Calling (magazine) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 establishments in England, 2004 disestablishments in England, BBC World Service, so understanding it makes those chapters shorter.
In everyday life: Look for London Calling (magazine) 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.
