Extractions: Professors Tom Humanic, Mike Lisa, and Evan Sugarbaker are members of the STAR collaboration. On June 12, 2000, the operators in the main control room of the Relativistic Heavy Ion Collider (RHIC) announced that the STAR detector captured the first spectacular images of particles streaming from a head-on collision point. Beams circulate in the colliders twin rings on a collision course at an energy of 30 billion electron volts (GeV) per nucleon. Later, events indicated that PHOBOS also detected the collisions. The result is great news to the thousands of physicists, engineers, and support staff who have been working since 1991 to get RHIC up and running, and to physicists everywhere who have been anticipating RHICs debut. These spectacular subatomic collisions are the culmination of many years of hard work, and they mark the beginning of a new era of discovery in nuclear physics. The kinds of high-energy collisions produced by this extraordinary machine should further enhance our understanding of the fundamental nature of matter. For the full news release, see the web site of the American Institute of Physics at www.aip.org.releases/ 2000/rhic.html. For more information and to follow RHICs progress, go to www.rhic.bnl.gov/. T he popular scientific press has dubbed string theory the so-called theory of everything. Everything is a lot. What researchers seek is a theory that would encompass both quantum mechanics and gravitation, thus unifying two great developments of the 20th century, Einsteins classical theory of general relativity and the quantum mechanics of Bohr and Schroedinger.

Professor t'Hooft, one of the world's leading physicists, is coming to Brussels to launch, together with Research Commissioner Philippe Busquin, a new batch of 167 training networks for young scientists from all over Europe. These networks, supported by the Commission through the Research Framework Programme, allow young researchers the chance to work and train with experienced scientists. The Commission will provide support through these networks for 4000 person-years of training to some of Europe's most talented young scientists over the next four years. Professor Gerardus t'Hooft, who is himself a partner in one of the new networks, will give a plenary lecture on the research that led to his award.
THE CREATION OF QUANTUM CHROMODYNAMICS AND THE EFFECTIVE ENERGY Two world leaders in subnuclear theoretical physics, Professors gerardus t Hooftand Gabriele Veneziano, illustrate the significance of the contributions of http://www.worldscientific.com/books/physics/4280.html
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: FIZIKAI NOBEL-DÍJ '99 Az 1999. évi fizikai Nobel-díj kitüntetettjei: Gerardus 't Hooft és Martinus J.G.Veltman "az elektrogyenge kölcsönhatás kvantumelméletének szilárd matematikai alapokra helyezéséért" A tizenkilencedik század folyamán alapvetõen megváltozott a világról alkotott kép. A századfordulóra az atomelmélet többé-kevésbé elfogadott nézetté vált. Csakhamar kiderült azonban, hogy amit atomnak neveztek - atom (gör.): oszthatatlan -, korántsem az, hanem egy belsõ pozitív töltésû magból , és az azt körülvevõ negatív elektronokból áll. De az atommag építõkövei, a pozitív proton és a semleges neutron sem bizonyultak kellõen elemieknek. Számos kísérleti eredmény utalt arra, hogy a proton és a neutron további részecskékbõl, az ún. kvarkokból állnak. Az 1950-es években aztán megépült az elsõ nagyteljesítményû gyorsítóberendezés , melyben olyan óriási energiával ütköztették össze a részecskenyalábokat, hogy feltárulhatott az anyag legbelsõ szerkezete. Az ütközések energiáját növelve sorra jelentek meg különféle, addig ismeretlen részecskék. Az ötvenes évek közepe táján aztán megfogalmazták az elsõ modern részecskefizikai elméletet. Ez volt az úgynevezett
