Robert Shapiro (chemist)
Robert Shapiro (28 November 1935 – 15 June 2011) was professor emeritus of chemistry at New York University. He is best known for his work on the origin of life, having written two books on the topic: ''Origins, a Skeptic’s Guide to the Creation of Life on Earth'' (1986) and ''Planetary Dreams'' (1999). He opposed the RNA world hypothesis, and held that the spontaneous emergence of a molecule as complicated as RNA is highly unlikely. Instead, he proposed that life arose from some self-sustaining and compartmentalized reaction of simple molecules: "metabolism first" instead of "RNA first". This reaction would have to be able to reproduce and evolve, eventually leading to RNA. He claimed that in this view life is a normal consequence of the laws of nature and potentially quite common in the universe.Alvin PowellNYU chemist Robert Shapiro decries RNA-first possibility ''Harvard University Gazette'', 23 October 2008 Works *''Life Beyond Earth: The Intelligent Earthling's Guide to ...

Robert H
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Gerald Feinberg
Gerald Feinberg (27 May 1933 – 21 April 1992) was a Columbia University physicist, futurist and populist author. He spent a year as a Member of the Institute for Advanced Study, and two years at the Brookhaven Laboratories. Feinberg went to Bronx High School of Science with Steven Weinberg and Sheldon Glashow and obtained his bachelor's and graduate degrees from Columbia University. His father was Yiddish poet and journalist Leon Feinberg. Among his students were Scott Dodelson, physicist at Carnegie Mellon University. Research He coined the term tachyon for hypothetical faster-than-light particles and analysed their quantum field properties, predicted the existence of the muon neutrino and advocated cryonics as a public service. He was a member of the Foresight Institute's advisory panel. Parapsychology Feinberg wrote a foreword to Edgar Mitchell's book ''Psychic Explorations'' (1974) in which he endorsed psychic phenomena.

RNA World Hypothesis
The RNA world is a hypothetical stage in the evolutionary history of life on Earth, in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. The term also refers to the hypothesis that posits the existence of this stage. Alexander Rich first proposed the concept of the RNA world in 1962, and Walter Gilbert coined the term in 1986. Alternative chemical paths to life have been proposed, and RNA-based life may not have been the first life to exist. Even so, the evidence for an RNA world is strong enough that the hypothesis has gained wide acceptance. The concurrent formation of all four RNA building blocks further strengthened the hypothesis. Regardless of its plausibility in a prebiotic scenario, the RNA world can serve as a model system for studying the origin of life. Like DNA, RNA can store and replicate genetic information; like protein enzymes, RNA enzymes (ribozymes) can catalyze (start or accelerate) chemical reactions that are crit ...

Shapiro Reaction
The Shapiro reaction or tosylhydrazone decomposition is an organic reaction in which a ketone or aldehyde is converted to an alkene through an intermediate hydrazone in the presence of 2 equivalents of organolithium reagent. The reaction was discovered by Robert H. Shapiro in 1967. The Shapiro reaction was used in the Nicolaou Taxol total synthesis. This reaction is very similar to the Bamford–Stevens reaction, which also involves the basic decomposition of tosyl hydrazones. Reaction mechanism In a prelude to the actual Shapiro reaction, a ketone or an aldehyde (1) is reacted with p-toluenesulfonylhydrazide, ''p''-toluenesulfonylhydrazide(2) to form a ''p''-toluenesulfonylhydrazone (or tosylhydrazone) which is a hydrazone (3). Two equivalents of strong base (chemistry), base such as N-Butyllithium, ''n''-butyllithium abstract the Hydron (chemistry), proton from the hydrazone (4) followed by the less carbon acid, acidic proton α to the hydrazone carbon (5), forming a carbanion. ...

Trotter Prize (Texas A&M)
The Trotter Prize (named after Dr. Ide P. Trotter Sr., former dean of the Texas A&M Graduate School.) is awarded at Texas A&M University and is part of an endowed lecture series. It is awarded "for pioneering contributions to the understanding of the role of information, complexity and inference in illuminating the mechanisms and wonder of nature" and includes The Trotter Lecture which "seeks to reveal connections between science and religion, often viewed in academia as non-overlapping, if not rival, worldviews. Previous winners Nobel Prize winners Charles Hard Townes and Francis Crick received the inaugural award at A&M's Rudder Theater in 2002. Townes spoke about connections between science and faith. Promoter of the notion of intelligent design William A. Dembski shared the award in 2005 with theoretical biologist Stuart Kauffman. Simon Conway Morris received the award and spoke in 2007.
