Extractions: Professor Veltman is known worldwide for his pioneering work on the renormalizability of gauge theories, having started this enterprise in 1968. The discovery that these theories are renormalizable, done with his student Gerardus 't Hooft, has revolutionized the field of particle physics. All interactionsweak, electromagnetic, and strongare described by a gauge theory, and the precise understanding of these theories has made it possible to extract precise predictions and quantities to be observed experimentally. Many of those predictions have been verified. After the discovery of the renormalizability of gauge theories, Professor Veltman was the first to start a systematic analysis of the calculation of radiative corrections. The methods developed by him, and his students, are the basis for that branch of research. Precision measurements at LEPthe large electron- positron collider at CERN, Geneva, Switzerlandhave by now confirmed the results in great detail, establishing firmly the above-mentioned principles of gauge theories and their renormalizability. In particular one may mention the discovery of certain radiative corrections that allowed a determination of the top quark mass well before it was actually discovered, with the actual value for the mass agreeing well with the value predicted by these radiative corrections.

Extractions: Why physics and high-energy theory? Every theorist has a dream to approach an ultimate theory of Nature, just as Michael E. Peskin wrote: " Even in this age of intellectual relativism, that there is something special about unraveling the behavior of Nature at the deepest possible level ", and a book of Steven Weinberg 's was entitled " Dreams of a final theory ". "A man who knows everything". This, reportedly, was Gerardus 't Hooft' s reply to a school teacher when asked what he would like to be when he grew up. Although as 't Hooft said: "but, still not knowing everything", and indeed, none of us could know everything, the desire to explore the unknown galvanized all physicists into studying physics. Witnessing their great achievements, moved by their strong will to unravel the secrets of the fundamental Laws of Nature and holding the belief that physics is the foundation of most discoveries in natural science, I choose physics as my major to study. For undergraduate students who want to have some flavors of high-energy theory, I recommend to read Gerardus't Hooft 's autobiography . It is really good

50 YEARS OF YANG-MILLS THEORY 50 Years of YangMills Theory edited by gerardus t hooft is both delightfuland deep. It begins with pages written in March 1947 by CN Yang, http://www.worldscibooks.com/physics/5601.html
Extractions: On the 50th anniversary of YangMills theory, this invaluable volume looks back at the developments and achievements in elementary particle physics that ensued from that beautiful idea. During the last five decades, Yang-Mills theory, which is undeniably the most important cornerstone of theoretical physics, has expanded widely. It has been investigated from many perspectives, and many new and unexpected features have been uncovered from this theory. In recent decades, apart from high energy physics, the theory has been actively applied in other branches of physics, such as statistical physics, condensed matter physics, nonlinear systems, etc. This makes the theory an indispensable topic for all who are involved in physics. An international team of experts, each of whom has left his mark on the developments of this remarkable theory, contribute essays or more detailed technical accounts to this volume. These articles highlight the new discoveries from the respective authors perspectives. The distinguished contributors are: S Adler, F A Bais, C Becchi, M Creutz, A De Rújula, B S DeWitt, F Englert, L D Faddeev, P Hasenfratz, R Jackiw, A Polyakov, V N Popov, R Stora, P van Baal, P van Nieuwenhuizen, S Weinberg, F Wilczek, E Witten, C N Yang. Included in each article are introductory and explanatory remarks by the editor, G t Hooft, who is himself a major player in the development of Yang-Mills theory.
Extractions: The University of Bologna and its Academy of Sciences, in collaboration with the Italian National Institute for Nuclear Physics and the Italian Physical Society, celebrated in 1998 the bicentenary of a great pioneer in the field of electric phenomena Luigi Galvani, the father of macroelectricity. During these two centuries, the physics of electric phenomena has given rise first to the Maxwell equations, then to quantum electrodynamics, and finally to the synthesis of all reproducible phenomena, the "Standard Model". A cornerstone of the Standard Model is quantum chromodynamics (QCD), which describes the interaction between quarks and gluons in the innermost part of the structure of matter. The discovery of QCD will be recalled in the future as one of the greatest achievements of mankind. Many physicists, the world over, have contributed to its creation on both the experimental and the theoretical front. Professor Antonino Zichichi has played an important role in this scientific venture, as documented by his works which are reproduced in this invaluable volume.

Extractions: Dutch researchers share Nobel Prize in Physics CNN, 12 October 1999 Two Dutch researchers who probed quantum theory won the 1999 Nobel Prize in physics, the first of two prize announcements planned Tuesday. Gerardus 't Hooft and Martinus J.G. Veltman won the award for their work on the quantum structure of electroweak interactions in physics. Dutch physicist Gerardus 't Hooft shared Nobel prize "Their work has given researchers a well-functioning theoretical machinery which can be used for, among other things, predicting the properties of new particles," the Royal Swedish Academy of Sciences said. Their calculations were vital in calculating the mass of the top quark, which was observed for the first time in 1995 at the Fermilab in the United States. "An important ingredient in the theory 't Hooft and Veltman have developed is an as-yet-undemonstrated particle termed the Higgs particle. In the same way as other particles have been predicted by theoretical arguments and later demonstrated experimentally, researchers are now awaiting direct observation of the Higgs particle," the academy said. Martinus Veltman and his colleague won a Nobel Prize in physics Veltman, of Bilthoven, the Netherlands, is retired from the University of Michigan, while 't Hooft has been a professor at the University of Utrecht since 1977. Their association began in 1969 when 't Hooft studied with Veltman.

Extractions: Known as "Father of the Laser", Prof Townes is University Professor of the University of California at Berkeley. In 1951, he conceived the idea of "masers" (microwave amplification by stimulated emission of radiation) and obtained the first amplification and generation of electromagnetic waves by stimulated emission in 1954. This groundbreaking work marked the beginning of the "laser era", culminating in his Nobel Prize in Physics in 1964, and lasers have since moved out of basic research into widespread applications. Prof Gerardus't Hooft Prof 't Hooft, Professor of Physics at the University of Utrecht, The Netherlands, specializes in elementary particle physics. His PhD thesis in 1971 solved the problem of renormalization of Yang-Mills fields, work in the gauge field theory that helped explain three out of four fundamental forces of the universe. He received the Nobel Prize in 1999 for placing particle physics theory on a firmer mathematical foundation. Prof 't Hooft's quest to account for the yet unresolved mystery of the fourth fundamental force, gravity, is still continuing.

Extractions: News for October 1999 12 October 1999 The 1999 Nobel Prize for Physics has been awarded to Gerardus 't Hooft and Martinus Veltman for their theoretical contributions to the Standard Model of particle physics. In the early 1970s 't Hooft and Veltman showed how to "renormalize" or remove the infinities from the electroweak theory of Salam and Weinberg, and how to use the theory to make precise calculations of particle properties. The official citation says that the prize has been awarded "for elucidating the quantum structure of electroweak interactions in physics." 't Hooft and Veltman were both born in the Netherlands. In 1966 Veltman was appointed as professor of physics at the University of Utrecht, and 't Hooft became his PhD student in 1969. By 1971 't Hooft had made several important breakthroughs in the theoretical effort to renormalize the electroweak interaction. Then using a computer program developed by Veltman, the pair verified 't Hooft's partial theory and showed how to perform precise calculations with it. Salam and Weinberg's theory had predicted the existence of the W and Z bosons, which carry the electroweak force, but their theory had to be renormalized before it could predict the physical properties of these particles, such as their masses. These predictions were confirmed when the W and Z particles were detected for the first time in 1984.
