Lisa Randall is a theoretical physicist working in particle physics and cosmology. She was born in Queens, New York City, on June 18, 1962. Lisa Randall is an alumna of Hampshire College Summer Studies in Mathematics; and she graduated from Stuyvesant High School in 1980. She won first place in the 1980 Westinghouse Science Talent Search at the age of 18; and at Harvard University, Lisa Randall earned both a BA in physics (1983) and a PhD in theoretical particle physics (1987) under advisor Howard Mason Georgi III, a theoretical physicist. She is currently Frank B. Baird, Jr. Professor of Science on the physics faculty of Harvard University, where he has been for the past a decade. Her works concerns elementary particles and fundamental forces, and has involved the study of a wide variety of models, the most recent involving dimensions. She has also worked on supersymmetry, Standard Model observables, cosmological inflation, baryogenesis, grand unified theories, and general relativity. Consequently, her studies have made her among the most cited and influential theoretical physicists and she has received numerous awards and honors for her scientific endeavors. Since December 27, 2010 at 00:42 (GMT+7), Lisa Randall is Twitter’s user with account @lirarandall. “Thanks to new followers. Interesting how different it feels broadcasting on line vs.via book or article. Explanations? Pithiness? Rapidity?” is her first tweet.

Understanding Of Science

Our understanding of science itself as a body of knowledge and as asystem of analysis and research has changed over the last decades, just asover the last two centuries, or especially after the age of Enlightement inEurope, science has become more powerful, more sophisticated and complex.It is rather difficult to determine where science ends and where technologybegins. In fact there is a gmwing awareness that the physical or nam sciences,as a means of studying and understanding nature, are relying on the more“humanistic“ and cultural approaches adopted by the social sciences or thehumanities. The tradition of natural science is being challenged by newdiscoveries of the non-physical and non-natural sciences which go beyondthe physical world.Certainly research is vital for the growth and development of all sciencesthat attempt to discover and understand the “secrets” of nature. The validityof any scientific theory depends on its research and methodological premisesand even that-its proposition or theories (in the words of a leading cosmologistand theoretical physicist, Stephen Hawking) -is tentative. Hawlung says: “Anyphysical theory is always provisional, in the sense that it is only a hypothesis:you can never prove it. No matter how many times the results of experimentsagree with some theory, you can never be sure that the next time the resultwill not contradict the theory. On the other hand, you can disprove a theoryby finding even a single observation that disagrees with the predictions ofthe theory.”The history of Western science is rooted in the idea of finding the ’truth’by objectivity. Nothing can be believed until there is a scientific proof ofits existence, or until it can be logically accepted by the rational mind. Theclassical scenario of scientific work gives you an austere picture of heroicactivity, undertaken against all odds, a ceaseless effort to subjugate hostileand menacing nature, and to tame its formidable forces. Science is depicted ...

Abstract We continue the study of a novel relation between quantum periods and TBA(Thermodynamic Bethe Ansatz)-like difference equations, generalize previous works to a large class of Calabi-Yau geometries described by three-term quantum operators. We give two methods to derive the TBA-like equations. One method uses only elementary functions while the other method uses Faddeev’s quantum dilogarithm function. The two approaches provide different realizations of TBA-like equations which are nevertheless related to the same quantum period.

Harry Jones was a theoretical physicist who made important contributions to the study of electrons in metals, and also, following work during the war, to our understanding of explosions. He was head of the department of mathematics at Imperial College, presiding over the postwar expansion in which it became one of the most important in the country.
