Key takeaways

Philip A. Cochran belongs to astronomy; place it in that map before memorising details.

Reference excerpt

Philip A. Cochran (1955 – 2015) was an American biologist who worked as a professor at St. Norbert College in De Pere, Wisconsin (1984 – 2000), and St. Mary’s University of Minnesota (2000 – 2015). Cochran earned a B.A. in Biology and Environmental Science at St. Mary’s University of Minnesota in 1977 (with high honors), an M.S. in Fisheries Science from the University of Minnesota in 1980, and a PhD in Zoology from University of Wisconsin in 1984, where at the Center for Limnology he first studied lampreys, the group of animals that would become his specialty. While best known as a leading Lamprey specialist, Cochran published hundreds of articles in refereed and non-refereed publications, as well as numerous book chapters, book reviews, and notes. He conducted much of his fieldwork in Wisconsin and Minnesota, and his research focused on a wide variety of fishes, amphibians, and reptiles of the upper Midwest. With John Lyons and Don Fago, Cochran coauthored the book Wisconsin Fishes 2000: Status and Distribution, which provided an updated overview of the status and abundance of fishes in Wisconsin. In 1991, during a sabbatical, he journeyed to central Mexico to help carry out the first comprehensive studies of the distribution, status, morphology, and ecology of the threatened non-parasitic Jacona lamprey and the endangered parasitic Chapala lamprey. In addition to his lamprey research, Cochran also collaborated with UW-Madison, St. Norbert, and Notre Dame researchers on the “Cascade” food-web project at the University of Notre Dame Ecological Research Center in the Michigan Upper Peninsula. Later in his career, Cochran extended his research interests into the historical, dealing with such subjects as captive timber rattlesnakes in Minnesota’s early history, rattlesnake bounties in Minnesota, the historical use of willow cats as bait in the Upper Mississippi River, and using newspapers as sources of historical information about lake sturgeon.

Worked examples

Example 1 — a first encounter with Philip A. Cochran

Start with the simplest possible case. Write down what Philip A. Cochran 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 Philip A. Cochran 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 Philip A. Cochran 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 Philip A. Cochran

In research: Philip A. Cochran 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 Philip A. Cochran 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: Philip A. Cochran is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 2015 deaths, American biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Philip A. Cochran 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.
