Reference excerpt

Lawrence Ray Heckard (1923–1991) was an American botanist and curator of the Jepson Herbarium. He was an authority on the flora of California with a focus on the genus Phacelia.

Biography Heckard was born in Long Beach, Washington on April 9, 1923. After serving in World War II, he earned his bachelor's degree in horticulture at Oregon State College in 1948. He finished his doctorate from the University of California, Berkeley in 1955. While at UC Berkeley, Heckard met his life partner Paul Silva. In 1960, Heckard was named assistant curator at the Jepson Herbarium. Here, he worked to revise The Jepson Manual. He also served as chairman to the American Society of Plant Taxonomists from 1961-1966, president of the California Botanical Society in 1971, and director of the California Native Plant Society. Heckard died of AIDS-related causes on November 26, 1991. The 1993 revision of The Jepson Manual was dedicated to him.

Worked examples

Example 1 — a first encounter with Lawrence Ray Heckard

Start with the simplest possible case. Write down what Lawrence Ray Heckard 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 Lawrence Ray Heckard 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 Lawrence Ray Heckard 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 Lawrence Ray Heckard

In research: Lawrence Ray Heckard 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 Lawrence Ray Heckard 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: Lawrence Ray Heckard is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1923 births, 1991 deaths, 20th-century American LGBTQ people, so understanding it makes those chapters shorter.
In everyday life: Look for Lawrence Ray Heckard 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.
