George Louderback

George Louderback is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand George Louderback rather than just read about it. In short: George Davis Louderback (April 6, 1874 – January 27, 1957) was an American geologist, known for identifying and describing benitoite and joaquinite. Biography Louderback was born in San Francisco, and received an A.B. from the University of California, Berkeley in 1896, followed by a Ph.D. in 1899.

Key takeaways

George Louderback belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect George Louderback to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of George Louderback from memory before moving on to harder problems.

Reference excerpt

George Davis Louderback (April 6, 1874 – January 27, 1957) was an American geologist, known for identifying and describing benitoite and joaquinite.

Biography Louderback was born in San Francisco, and received an A.B. from the University of California, Berkeley in 1896, followed by a Ph.D. in 1899. He married Clara Augusta Henry on October 3, 1899. He was a teaching assistant in mineralogy at UC Berkeley in 1897–1900 and then taught at the University of Nevada in 1900–1906. At UC Berkeley's department of geology, Louderback became an assistant professor in 1906, an associate professor in 1907, and a full professor in 1917. In Nevada, Louderback studied the geological structure of the Great Basin, especially of the Basin ranges, and Nevada's gypsum deposits. He did research on the Mesozoic formations of southern Oregon, the relation of radioactivity to vulcanism, the glaucophane of the Pacific Coast Ranges, and the stratigraphy of Mount Diablo. He also studied the effects of the 1906 San Francisco earthquake and sedimentation in San Francisco Bay. In 1914–1916 Louderback led an expedition searching for petroleum reservoirs in the interior of China; after the expedition, in 1916 he also searched for petroleum in the Philippine Islands. He was a member of the Seismological Society of America and its president in 1914 and again in 1929–1935. He died in Berkeley, California on January 27, 1957, aged 82. In 1972, the Louderback Mountains in central Nevada were named for Louderback.

Worked examples

Example 1 — a first encounter with George Louderback

Start with the simplest possible case. Write down what George Louderback claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 George Louderback 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 George Louderback 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 George Louderback

In research: George Louderback appears in astronomy 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 George Louderback 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: George Louderback is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1874 births, 1957 deaths, American geologists, so understanding it makes those chapters shorter.
In everyday life: Look for George Louderback 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.
