Reference excerpt

Raphael David Levine (Hebrew: רפאל לוין; born March 29, 1938) is an Israeli chemist who is a professor at the Hebrew University of Jerusalem, and the Department of Chemistry and Biochemistry, University of California, Los Angeles and the Crump Institute for Molecular Imaging of the David Geffen School of Medicine at UCLA.

Biography Raphael David Levine was born on March 29, 1938, in Alexandria, Egypt.

Academic career He is the Max Born professor of Natural Philosophy at the Hebrew University of Jerusalem and a distinguished professor at the University of California, Los Angeles. He is known for his contributions in the modern theory of chemically reactive collisions and unimolecular reactions. He has played a major role in the application of the principles of quantum mechanics to the description of physical change in a reaction from a microscopic point of view, introducing many new concepts and terms which became standard to this area. His major works include the quantum theory of absolute rates, the first quantal treatment of molecular photodissociation, elucidation of the role of resonances in reactive molecular collisions, the theory of collision- induced dissociation, and the foundations of dynamical stereochemistry. He is a member of Israel Academy of Sciences and Humanities, the Max Planck Society, Academia Europaea, American Academy of Arts & Sciences, American Philosophical Society, Royal Danish Academy of Sciences and Letters, and National Academy of Sciences of the United States. He has honorary doctorates from Liege University, 1991 and the Technical University of Munich 1996. His 2005 book, "Molecular Reaction Dynamics", Cambridge University Press, was selected by Choice as 'Outstanding Academic Title 2006'.

Awards and recognition 1968: Annual Prize of the Academy. 1974: Israel Prize, in exact science. 1979: Weizmann Prize. 1988: he was awarded the Wolf Prize in Chemistry along with Joshua Jortner of Tel Aviv University "for their incisive theoretical studies elucidating energy acquisition and disposal in molecular systems and mechanisms for dynamical selectivity and specificity". 1992: Rothschild Prize. 1996: Max Planck Prize for International Cooperation 2001: EMET Prize

Worked examples

Example 1 — a first encounter with Raphael David Levine

Start with the simplest possible case. Write down what Raphael David Levine 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 Raphael David Levine 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 Raphael David Levine 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 Raphael David Levine

In research: Raphael David Levine 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 Raphael David Levine 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: Raphael David Levine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, 21st-century Egyptian Jews, Academic staff of the Hebrew University of Jerusalem, so understanding it makes those chapters shorter.
In everyday life: Look for Raphael David Levine 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.
