This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Leslie R. Landrum rather than just read about it. In short: Leslie Roger Landrum (born 1946) is an American botanist serving as senior research scientist at Arizona State University School of Life Sciences, and curator of the ASU Vascular Plant Herbarium. He attained M.S. and Ph.D. degrees from the University of Michigan, and has been at Arizona State University since 1986.

Key takeaways

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

Reference excerpt

Leslie Roger Landrum (born 1946) is an American botanist serving as senior research scientist at Arizona State University School of Life Sciences, and curator of the ASU Vascular Plant Herbarium. He attained M.S. and Ph.D. degrees from the University of Michigan, and has been at Arizona State University since 1986. From 1969 to 1973, he worked with the Peace Corps at the Forestry School of the University of Chile, where he gained an interest in the flora of South America, particularly the myrtle family (Myrtaceae). Since then, he has published descriptions of new genera and species within the South American Myrtaceae, devoting particular study to the genus Psidium (which includes the commercially important guava). Other concentrations include the Chilean species of the widespread genus Berberis, the usage of computer models in evaluating methods of phylogenetic analysis, and serving on a committee of botanists (including D.J. Pinkava) working on a new manual of the vascular plants of Arizona to replace the aging Arizona Flora by Kearney and Peebles (last updated in 1960). He is on the editorial board of the Journal of The Arizona–Nevada Academy of Science, and since 2005, he has been the editor of Canotia: A New Journal of Arizona Botany. Landum is one of the original scientists to participate in the Ask A Biologist program and the subject of the "Smashing Success" article detailing his work with ASU Vascular Plant Herbarium.

Worked examples

Example 1 — a first encounter with Leslie R. Landrum

Start with the simplest possible case. Write down what Leslie R. Landrum 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 Leslie R. Landrum 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 Leslie R. Landrum 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 Leslie R. Landrum

In research: Leslie R. Landrum 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 Leslie R. Landrum 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: Leslie R. Landrum is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, 21st-century American botanists, Arizona State University faculty, so understanding it makes those chapters shorter.
In everyday life: Look for Leslie R. Landrum 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.
