Key takeaways

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

Reference excerpt

Tyler Eugene Nordgren (November 18, 1969) is an astronomer and professor of physics at the University of Redlands.

Education Nordgren earned a B.A. in physics from Reed College and an M.S. and Ph.D. in astronomy from Cornell University.

Research Before joining the University of Redlands in 2001, Nordgren was an astronomer at the United States Naval Observatory Flagstaff Station and Lowell Observatory. In 2004, with six other astronomers and artists, Nordgren helped develop MarsDials, functioning sundials that NASA's Spirit, Opportunity, and Curiosity rovers carried with them to Mars. Nordgren also designed the giant sundial that resides on the wall of Appleton Hall at the University of Redlands and is accurate within 10 minutes. For the past five years, Nordgren has been traveling around the U.S. to educate the public about what eclipses are and how the opportunity to see the total solar eclipse on August 21, 2017 should not be missed. More of Nordgren's research on eclipses can be found in his most recent book Sun Moon Earth: The History of Solar Eclipses from Omens of Doom to Einstein and Exoplanets (Basic Books, 2016).

Collaboration with U.S. National Park Service Nordgren has been a member of the National Park Service Night Sky Team since 2007, working with the U.S. National Park Service to protect the night skies and promote astronomy education in U.S. national parks. Nordgren has helped document the parks' night skies with photography that has been on display in galleries from New York City to Flagstaff, Arizona, and is on display in a number of national parks. The Acadia Night Sky Festival has featured many of his photographs. Nordgren has also developed a poster campaign in conjunction with the National Park Service to “See the Milky Way” in America’s parks where “Half the Park is After Dark.” His 2010 book Stars Above, Earth Below: A Guide to Astronomy in the National Parks (Praxis, 2010) was published as a way to spread the message of the importance of protecting the night sky.

Professional affiliations Nordgren was elected to the board of directors of the International Dark-Sky Association (IDA) in 2011. He is also a member of the American Astronomical Society.

Worked examples

Example 1 — a first encounter with Tyler Nordgren

Start with the simplest possible case. Write down what Tyler Nordgren 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 Tyler Nordgren 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 Tyler Nordgren 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 Tyler Nordgren

In research: Tyler Nordgren 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 Tyler Nordgren 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: Tyler Nordgren is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 births, American astronomers, Cornell University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Tyler Nordgren 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.
