Ralph A. Lewin

Ralph A. Lewin is a biology 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 Ralph A. Lewin rather than just read about it. In short: Ralph Arnold Lewin (30 April 1921 – 30 November 2008) was an Anglo-American biologist, known as "the father of green algae genetics". He was born in London and later moved to America.

Key takeaways

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

Reference excerpt

Ralph Arnold Lewin (30 April 1921 – 30 November 2008) was an Anglo-American biologist, known as "the father of green algae genetics". He was born in London and later moved to America. He also was known as a poetry author.

Education He studied at University of Cambridge from 1939 to 1947, graduating with a B.A. in 1942 and MA in 1946, whilst at Cambridge he focussed on Botany. He then studied at Yale University from 1947 to 1951, graduating with an M.S. in 1949 and a PhD in Botany in 1950. In 1971 (or 1972), he was made a Doctor of Science (Sc.D.) of the University of Cambridge.

Biography Lewin spent nearly 48 years at the Scripps Institution of Oceanography at the University of California at San Diego and was considered a leading authority in multiple areas of marine biology. Lewin joined the Scripps Institution as an associate professor of marine biology in 1960 and retired from that position as a full professor in 1991, remaining extremely active in laboratory and field research and lecturing nationally and internationally. He helped organize and teach courses on marine microbiology and algae for the United Nations Educational, Scientific and Cultural Organization in Finland, Singapore, and China. He published more than 250 scientific papers, among which his 2001 review paper entitled More on Merde was an entertaining review on the worth of feces in biomedicine. He addressed this issue frankly by stating, "Whereas food has always received much attention in conversation, commerce, and the literature, the subject of feces has been comparatively neglected. To fill this lacuna, a small book on comparative coprology was recently published (Lewin 1999). The present article aims to supplement this book with a review of overlooked or new items relating to biological and medical aspects of coprology, notably chemical and microbial components of human and animal feces, their uses as fertilizers, and a few other sociological impacts." Ralph Lewin was an Esperantist, and was Ordinary Professor (orda profesoro) at Akademio Internacia de la Sciencoj San Marino, the only university in the world where all courses are studied in Esperanto. He translated Winnie-the-Pooh into Esperanto with Ivy Kellerman Reed, and was the author of Merde: excursions in scientific, cultural and socio-historical coprology.

Worked examples

Example 1 — a first encounter with Ralph A. Lewin

Start with the simplest possible case. Write down what Ralph A. Lewin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Ralph A. Lewin 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 Ralph A. Lewin 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 Ralph A. Lewin

In research
Ralph A. Lewin appears in biology 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 Ralph A. Lewin 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
Ralph A. Lewin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1921 births, 2008 deaths, 20th-century American biologists, so understanding it makes those chapters shorter.
In everyday life
Look for Ralph A. Lewin 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.
