Reference excerpt

Murphy Radio was a British manufacturer of radios and televisions based in Welwyn Garden City, England.

History

1929: inception Murphy Radio was founded in 1929 by Frank Murphy and E.J. Power as a volume manufacturer of home radio sets. Its factories were in the Hertfordshire town of Welwyn Garden City, England, starting with fewer than 100 employees. Murphy also had a manufacturing facility in Islandbridge, Dublin, Ireland.

1939+: expansion

The company played an important role during World War II, designing and manufacturing radio sets for British Armed Forces use, chiefly the Wireless Set No. 38. After the war, Murphy used its military experience to design and build sets for Naval use, principally the 'B40' series for the British Commonwealth Navies. The company also produced the Larkspur era A41 VHF manpack transceiver for the British Army during the 1950s. Murphy himself left the company during 1937 and went on to found another company called, perhaps unwisely, 'FM Radio'. He died aged 65, in 1955.

1959 onward The company became well known for the manufacture of television sets and was successful up until 1959 when it encountered trading difficulties, similar to others in the industry. In 1962, The Rank Organisation thought there might be advantages if they merged Murphy with their Bush Radio business. As part of the acquisition and reorganisation by Rank, Murphy acquired the undertaking and assets of Bush as well as Rank Cintel, Rank's electronic division.

Current status The brand 'Murphy' has survived, but as a licensee for Far Eastern electronics.

In popular media In 2012, the brand gained attention in India due to the movie Barfi!. A vintage Murphy radio also appears in the opening of the 2012 film Life of Pi.

Worked examples

Example 1 — a first encounter with Murphy Radio

Start with the simplest possible case. Write down what Murphy Radio 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 Murphy Radio 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 Murphy Radio 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 Murphy Radio

In research: Murphy Radio 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 Murphy Radio 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: Murphy Radio is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 establishments in England, 1962 disestablishments in England, Companies based in Welwyn Hatfield, so understanding it makes those chapters shorter.
In everyday life: Look for Murphy Radio 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.
