Richard Lawrence Edwards

Richard Lawrence Edwards is a chemistry 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 Richard Lawrence Edwards rather than just read about it. In short: Richard Lawrence "Larry" Edwards is an American geochemist and Distinguished McKnight University Professor and Regents Professor at the University of Minnesota. He is one of the most cited and respected geochemists in the world, and is well-known for his contributions to modernizing the uranium-thorium (Th-230) radiometric dating technique.

Key takeaways

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

Reference excerpt

Richard Lawrence "Larry" Edwards is an American geochemist and Distinguished McKnight University Professor and Regents Professor at the University of Minnesota. He is one of the most cited and respected geochemists in the world, and is well-known for his contributions to modernizing the uranium-thorium (Th-230) radiometric dating technique. Edwards earned his Ph.D from the California Institute of Technology in 1988 after studying under Gerald J. Wasserburg. His thesis, entitled High Precision Thorium-230 Ages of Corals and the Timing of Sea Level Fluctuations in the Late Quaternary, discusses the usage of Th-230 dating in the examination of corals at Santo and Malekula Islands, Vanuatu. Edwards has made notable contributions to anthropology through dating a jawbone at 100000 years old, suggesting that modern humans had inhabited the area of China where the bone was found earlier than previously thought. His collaborations with geochemist Hai Cheng have led to the largest number of environmental science papers published in Nature Index journals by a pair of geochemists. On January 3rd, 2025, Dr. Edwards received the National Medal of Science.

Worked examples

Example 1 — a first encounter with Richard Lawrence Edwards

Start with the simplest possible case. Write down what Richard Lawrence Edwards claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Richard Lawrence Edwards 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 Richard Lawrence Edwards 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 Richard Lawrence Edwards

In research: Richard Lawrence Edwards appears in chemistry 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 Richard Lawrence Edwards 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: Richard Lawrence Edwards is common in secondary-school and first-year university syllabi. It links to neighbouring topics American geochemists, California Institute of Technology alumni, Earth scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Lawrence Edwards 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.
