He received the Nobel Prize for Physics in 1969 “for his contributions and discoveries concerning the classification of elementary particles and their interactions”. Sheldon Glashow is a Professor of Physics at Boston University, as well as the Higgins Professor of Physics Emeritus at Harvard University. He received the Nobel Prize for Physics in 1979 “for contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current”. David Gross is the Director of the Kavli Institute for Theoretical Physics at the University of California at Santa Barbara and holds the Frederick W. Gluck Professorship of Theoretical Physics. He received the Nobel Prize for Physics in 2004 “for the discovery of asymptotic freedom in the theory of the strong interaction”. Paul Steinhardt is the Albert Einstein Professor in Science at Princeton University, a member of the faculty in the Department of Physics, and an associate faculty member in the Department of Astrophysical Sciences. He received the P.A.M. Dirac Medal from the International Centre for Theoretical Physics in 2002. Lawrence Summers is President of Harvard University. Formerly he had been a professor of economics at Harvard, and served under President Clinton as Secretary of the Treasury. Frank Wilczek is the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology. He was awarded the Nobel Prize for Physics in 2004 “for the discovery of asymptotic freedom in the theory of the strong interaction”. Erick Weinberg is a Professor of Physics, as well as Chair of the Department of Physics at Columbia University. His major interest is elementary particle theory, including the study of topological and nontopological solitons. Steven Weinberg holds the Josey Regental Chair in Science at the University of Texas at Austin, a member of the Physics and Astronomy Departments. He was awarded the Nobel Prize for Physics in 1979 “for contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, including, inter alia, the prediction of the weak neutral current”. Gerard ’t Hooft is a Professor of Theoretical Physics at the Institute for Theoretical Physics at the Universiteit Utrecht. He received the Nobel Prize for Physics in 1999 “for elucidating the quantum structure of electroweak interactions in physics”. Edward Witten is a Professor in the School of Natural Sciences at the Institute for Advanced Study in Princeton, New Jersey. He received the Fields Medal in 1990 “for his work connecting theoretical physics to modern mathematics”. About Sidney Coleman Sidney was born on March 7, 1937 in Chicago. He received his Bachelor of Science degree from Illinois Institute of Technology in 1957, and his Ph.D. from the California Institute of Technology in 1962. He came to Harvard in 1961 and now is the Donner Professor of Science. Not only was Sidney instrumental in the discovery of asymptotic freedom and the understanding of its consequences (ultimately resulting in the 2004 Nobel Prize). But in his generation he was the “number one” expositor of new ideas in renormalization theory and symmetry, both to experts as well as to students. His legendary lectures at Harvard and at numerous summer schools in Erice, Sicily, inspired a whole generation of young physicists.
