Reference excerpt

John Karl Hillers (1843, Hanover, Germany – 1925) was an American government photographer. Hillers came to the United States in 1852. He was a policeman and then a soldier in the American Civil War, first with the New York Naval Brigade, then in the army, he re-enlisted after the war and served with the Western garrisons until 1870. He worked as a teamster in Salt Lake City, when he met John Wesley Powell. Originally hired as a boatman for the second Powell expedition down the Colorado River in 1871, Hillers began to replace Walter Clement Powell, John W. Powell's cousin and assistant to the expedition's photographers, first to E.O. Beaman and then to James Fennemore. Hillers was Powell's chief expedition photographer on the trip down the Grand Canyon the next year. He went on to spend twenty years exploring and photographing the American West, and is known particularly for his portraits of Native Americans. He was the first staff photographer of Powell's Bureau of Ethnology (from 1879) and after returning to Powell's US Geological Survey in 1881 continued Bureau of American Ethnology work until he resigned in 1900. Although he officially retired in 1900, he continued to take photographs for the United States Geological Survey until 1919. He was the photographer of the first James Stevenson expedition to the Southwest, which brought Frank H. Cushing to Zuni. 3,000 negatives from the Powell Surveys and 20,000 negatives from his association with the Bureau of Ethnology have been credited to John K. Hillers. John Karl Hillers is the namesake of Mount Hillers, in Utah.

Worked examples

Example 1 — a first encounter with John Karl Hillers

Start with the simplest possible case. Write down what John Karl Hillers claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 John Karl Hillers 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 John Karl Hillers 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 John Karl Hillers

In research: John Karl Hillers appears in earth 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 John Karl Hillers 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: John Karl Hillers is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1843 births, 1925 deaths, American male photographers, so understanding it makes those chapters shorter.
In everyday life: Look for John Karl Hillers 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.
