Loren Acton

Loren Acton 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 Loren Acton rather than just read about it. In short: Loren Wilber Acton (born March 7, 1936) is an American physicist who flew on Space Shuttle mission STS-51-F as a Payload Specialist for the Lockheed Palo Alto Research Laboratory. He is also the father of Cheryll Glotfelty, a leading ecocritic.

Key takeaways

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

Reference excerpt

Loren Wilber Acton (born March 7, 1936) is an American physicist who flew on Space Shuttle mission STS-51-F as a Payload Specialist for the Lockheed Palo Alto Research Laboratory. He is also the father of Cheryll Glotfelty, a leading ecocritic.

Early life and education Acton was born in Lewistown, Montana. He received a bachelor of science degree in Engineering Physics from Montana State University in 1959, and a Doctor of Philosophy in astrophysics from the University of Colorado at Boulder in 1965.

Career Acton was a senior staff scientist with the Space Sciences Laboratory, Lockheed Palo Alto Research Laboratory, California. As a research scientist, his principal duties included conducting scientific studies of the Sun and other celestial objects using advanced space instruments and serving as a co-investigator on one of the Spacelab 2 solar experiments, the Solar Optical Universal Polarimeter. He was selected as one of four payload specialists for Spacelab 2 on August 9, 1978, and after seven years of training he flew on STS-51-F/ Spacelab-2 in 1985. At the conclusion of the mission, Acton had travelled over 2.8 million miles in 126 Earth orbits, logging over 190 hours in space. Acton is married and has two children. In 2006 he ran in an election to be the state representative of Montana's District 69, as a Democratic candidate. In the event, he lost to the Republican incumbent, Jack M. Wells of Belgrade. Acton is currently retired from his role as a Research Professor of Physics at Montana State University, where he was responsible for the formation of the Solar Physics group and the Space Science and Engineering Laboratory. The MSU solar group carries on an active research program under NASA and NSF support and is actively involved in day-to-day operation and scientific utilization of satellite missions for studies of the Sun. Acton was a principal investigator for Soft X-ray Telescope (SXT) experiment on the Japan/US/UK Yohkoh mission "Yohkoh Legacy Archive". The Yohkoh mission focused on the study of high-energy solar processes, such as solar flares, eruptions and the heating of the corona. The primary emission of the extremely hot outer atmosphere of the Sun, the solar corona, is at X-ray wavelengths. The extended duration, high resolution, X-ray imagery from Yohkoh contribute to the study of why the Sun has a corona at all and why it varies in intensity so strongly in response to the 11-year sunspot cycle.

Worked examples

Example 1 — a first encounter with Loren Acton

Start with the simplest possible case. Write down what Loren Acton 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 Loren Acton 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 Loren Acton 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 Loren Acton

In research: Loren Acton 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 Loren Acton 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: Loren Acton is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 21st-century American physicists, American astronaut-politicians, so understanding it makes those chapters shorter.
In everyday life: Look for Loren Acton 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.
