Thomas Brennan Nolan is a earth science 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 Thomas Brennan Nolan rather than just read about it. In short: Thomas Brennan Nolan (May 21, 1901 – August 2, 1992) was an American geologist who was the seventh director of the United States Geological Survey (USGS) from 1956 to 1965. The mineral nolanite is named in his honor and he was an elected member of the American Academy of Arts and Sciences, the United States National Academy of Sciences, and the American Philosophical Society.

Key takeaways

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

Reference excerpt

Thomas Brennan Nolan (May 21, 1901 – August 2, 1992) was an American geologist who was the seventh director of the United States Geological Survey (USGS) from 1956 to 1965. The mineral nolanite is named in his honor and he was an elected member of the American Academy of Arts and Sciences, the United States National Academy of Sciences, and the American Philosophical Society. He was generally known as Tom Nolan.

Early life Nolan was born in Greenfield, Massachusetts in 1901. He was educated at New Haven, Connecticut, then studied Metallurgy at Yale University, graduating with a BS in 1921. He continued studying at Yale and received a PhD in Geology in 1924. After training for the Civil Service he joined the US Geological Survey,

USGS career After Director William Embry Wrather retired because of illness and age in 1955, Assistant Director Thomas B. Nolan became the 's (USGS) seventh director in January 1956. During his 11 years as an Assistant Director, Nolan had many times and for extended periods served as an Acting Director so no transition period was needed. Nolan believed that geologists, because of the unique requirements imposed on them by their science, should expand their fields of interest from individual problems and "participate actively and authoritatively in the matters affecting the whole country." Until September 1965, when he resumed his research in Great Basin geology, Nolan pushed, prodded, and led the Survey to a broadened and intensified commitment to basic research, to the advancement of geology in the public service, and to the prompt publication of Survey results. As Assistant Director, he had also served as the Interior Department representative on the Interdepartmental Committee on Scientific Research and Development, on the Scientific Advisory Committee on Specialized Personnel to the Selective Service Committee, and on the Advisory Board on Education of the National Academy of Sciences, and had been president of the Society of Economic Geologists and the Geological Society of America (1961). As Director, his professional responsibilities outside the Survey were still further extended to service as vice president and president of the Geological Society of America, as vice president of the International Union of Geological Sciences, and on committees advisory to university geology departments. In 1956, the Geological Survey began an evaluation of the effects of underground nuclear explosions at the Atomic Energy Commission's Nevada Test Site; that program was expanded to study the geologic and hydrologic conditions affecting the peaceful uses of atomic energy and the disposal of radioactive wastes. In December 1958, Director Nolan, speaking at the meeting of the American Association for the Advancement of Science, remarked that the early work of the Geological Survey had been characterized by a transition from exploration of a geographical to an intellectual frontier, but demands by younger scientists for studies of the geography of outer space might soon inaugurate a new cycle in the history of the US Geological Survey. In 1959, the Survey compiled a photogeologic map of the Earth's satellite, the Moon, and began studies of tektites and impact craters. On May 25, 1961, President John F. Kennedy proposed as a goal "landing a man on the moon and returning him safely to earth" before the end of the decade, and in 1963, the US Geological Survey, in cooperation with the National Aeronautics and Space Administration, began to train astronauts in geology and to investigate and evaluate methods and equipment for geological and geophysical exploration of the Moon. He died in Washington, D.C., on August 2, 1992.

Family He was married to Mabel ("Pete") Orleman (d.1983). They had one son.

Worked examples

Example 1 — a first encounter with Thomas Brennan Nolan

Start with the simplest possible case. Write down what Thomas Brennan Nolan 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 Thomas Brennan Nolan 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 Thomas Brennan Nolan 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 Thomas Brennan Nolan

In research
Thomas Brennan Nolan 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 Thomas Brennan Nolan 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
Thomas Brennan Nolan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1901 births, 1992 deaths, 20th-century American geologists, so understanding it makes those chapters shorter.
In everyday life
Look for Thomas Brennan Nolan 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.
