Reference excerpt

Harry Arthur Crowhurst (14 March 1868 – 8 December 1943) was a photographer, optician and partner in a lantern and optical supply business.

Life and Times In 1868, Crowhurst was born at St George the Martyr, London. He was the son of William Henry and Julia Ann Crowhurst. He had one brother, Walter William, and 2 sisters, Ellen Mable and Julia May. In 1943, he died at Southampton, Hampshire, England. In 1891, the Census of England and Wales noted that Crowhurst, age 23, had the occupation as optician. In 1900, he teamed with Harold Armytage Sanders to form the firm of Sanders and Crowhurst. In 1901, the Census of England and Wales noted that Crowhurst, age 33, listed occupation as optician. In May 1905, Crowhurst married the daughter of James Williamson, noted film pioneer, and took over the Williamson business.

W. Watson and Son W. Watson and Son was an optical instrument maker. In 1837, the William Watson business was established in London for the manufacture of optical instruments. By the 1840s, the company moved into lanterns, slides and associated equipment. In 1868, the name was changed to W. Watson & Son and by this time were located at 313 High Holborn, London. In the 1870s, the company added photographic equipment and became known as a leading manufacturer of the Highest Class Photographic Instruments and Apparatus in England. Into the 1940s, the company remained at 313 High Holborn, London, England.

Sanders & Crowhurst

Established in 1900, Crowhurst teamed with Harold Armytage Sanders to form the firm of Sanders and Crowhurst that became an agent for W. Watson and Son. The going interest was to serve as lantern and slide dealers and also offer service as opticians. The partnership dissolved on 21 October 1908. When the partnership dissolved in 1908, Sanders continued in business as Sanders and Company at the Shaftesbury Avenue address, and Crowhurst continued in business at the Hove branch location.

Worked examples

Example 1 — a first encounter with Harry Arthur Crowhurst

Start with the simplest possible case. Write down what Harry Arthur Crowhurst 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 Harry Arthur Crowhurst 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 Harry Arthur Crowhurst 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 Harry Arthur Crowhurst

In research: Harry Arthur Crowhurst 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 Harry Arthur Crowhurst 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: Harry Arthur Crowhurst is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1868 births, 1943 deaths, British opticians, so understanding it makes those chapters shorter.
In everyday life: Look for Harry Arthur Crowhurst 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.
