Lee R. Dice

Lee R. Dice 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 Lee R. Dice rather than just read about it. In short: Lee Raymond Dice (July 15, 1887 – January 31, 1977) was an American ecologist and geneticist who taught at the University of Michigan for almost his entire career. He is known for independently developing the Sørensen–Dice coefficient.

Key takeaways

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

Reference excerpt

Lee Raymond Dice (July 15, 1887 – January 31, 1977) was an American ecologist and geneticist who taught at the University of Michigan for almost his entire career. He is known for independently developing the Sørensen–Dice coefficient.

Education and career Dice was born in Savannah, Georgia and studied briefly at Washington State College and University of Chicago before moving to Stanford University. He earned his A.B. from Stanford University in 1911, followed by an M.S. and Ph.D. from the University of California, Berkeley in 1914 and 1915, respectively. For his M.S. project, Dice worked on the movements of water fleas under Samuel Jackson Holmes. During his Ph.D., he worked under Joseph Grinnell on vertebrates in the Washington state. After graduation, Dice took on the role of an instructor in zoology at Kansas State Agricultural College (now Kansas State University) from 1916 to 1917 and later served as an assistant professor of zoology at the University of Montana from 1917 to 1918. Between 1918 and 1919, Dice worked at the U.S. Biological Survey and the Michigan Biological and Geological Survey as a field assistant. He began teaching at the University of Michigan in 1919 as an assistant professor and became a professor in 1942. He taught at the University of Michigan until 1957, during which time he founded the University's heredity clinic and served as director of its Institute of Human Biology.

Honors and awards Dice served as vice-president of the American Society of Mammalogists from 1947 to 1951 and the vice-president of the Society for the Study of Evolution between 1947 and 1948 and between 1953 and 1954. In 1948, Dice became the president of the Ecologists Union, later known as the Nature Conservancy. He served as president of the Ecological Society of America from 1952 to 1953 and received its Eminent Ecologist Award in 1964. In 1957, the University of Michigan honored him by creating the Lee R. Dice Distinguished Professorship.

Worked examples

Example 1 — a first encounter with Lee R. Dice

Start with the simplest possible case. Write down what Lee R. Dice 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 Lee R. Dice 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 Lee R. Dice 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 Lee R. Dice

In research: Lee R. Dice 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 Lee R. Dice 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: Lee R. Dice is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1887 births, 1977 deaths, 20th-century American people, so understanding it makes those chapters shorter.
In everyday life: Look for Lee R. Dice 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.
