Dicembre '99 Il Nobel per LA FISICA 1999: Gerardus 't Hooft e Martinus Veltman A metà del secolo XX 4 erano le forze fondamentali note della fisica: forza elettromagnetica, forza gravitazionale, forza nucleare debole e forza nucleare forte. Il premio Nobel per la fisica del 1999 è stato assegnato congiuntamente ai due fisici olandesi Gerardus 't Hooft e a Martinus J. G. Veltman con la motivazione ufficiale di aver spiegato la struttura quantistica dell'interazione elettrodebole in fisica. Si tratta della teoria che unifica la forza elettromagnetica e la forza nucleare debole. La protezione del patrimonio naturale italiano In Italia la superficie di territorio protetta da parchi è triplicata in pochi anni: merito della nuova coscienza ambientalista di questi ultimi anni e dell'approvazione di leggi di tutela che hano contribuito alla salvaguarda di veri gioielli del paesaggio italiano. Un fatto certamente positivo che però non deve far cantare vittoria a nessuno visto che sono ancora molti i casi di cattiva gestione del territorio. Il Nobel per l'economia 1999: Robert Mundell Quello a Robert Mundell può essere definito un premio Nobel con valore retroattivo visto che le teorie per le quali è stato premiato risalgono agli anni Sessanta. Considerato come il l'inventore della moderna macroeconomia dell'economia aperta, Mundell fu infatti il primo a dimostrare che gli effetti delle politiche stabilizzatrici dipendevano dal livello della mobilità dei capitali e in particolare dal regime di cambio.

reflections See also commentary meditation Contents: March/April 2002 p r o p h e c y The Dispossessed by 100 Nobel Laureates The following statement was released on December 7, 2001, by 100 Nobel Prize winners to coincide with the celebration of the 100th anniversary of the first Nobel prizes. Although the statement began circulating among the laureates last summer, most of them signed it after September 11. The most profound danger to world Peace in the coming years will stem not from the irrational acts of states or individuals but from the legitimate demands of the world's dispossessed. Of these poor and disenfranchised, the majority live a marginal existence in equatorial climates. Global warming, not of their making but originating with the wealthy few, will affect their fragile ecologies most. Their situation will be desperate and manifestly unjust. It cannot be expected, therefore, that in all cases they will be content to await the beneficence of the rich. If then we permit the devastating power of modern weaponry to spread through this combustible human landscape, we invite a conflagration that can engulf both rich and poor. The only hope for the future lies in cooperative international action, legitimized by democracy. It is time to turn our backs on the unilateral search for security, in which we seek to shelter behind walls. Instead, we must persist in the quest for united action to counter both global warming and a weaponized world.

VELTMAN University of Michigan (emeritus) An elegant and compelling theory is of no use if its predictions are wrong or, worse still, nonsensical. Elementary particle physicists confronted such problems at regular intervals in the 20th century as they tried to apply quantum field theory to describe experiments. Quantum field theory describes particles, fields and forces with a common language, but it produces intractable equations that are typically solved by successive approximations. Alas, when applied to electromagnetism, this method produced preposterous infinite terms. Such problems were fixed in the 1940s by "renormalization," which collects infinities together and absorbs them into a small number of finite parameters. This "approximation" scheme yields predictions that agree with experiment to 10 decimal placesthe most precise in all of science.

Bollinger, who plans to return from Stockholm on Monday, said he is honored to be among Veltman's invited guests. "It is very special to me and Jean," Bollinger said because Veltman "wanted us to come and represent the University." In October, Veltman, an expert in theoretical physics, was named a prize winner along with his colleague, Prof. Gerardus t'Hooft of the University of Utrecht in the Netherlands. After the news of the Nobel Award was announced, Veltman returned to Ann Arbor, giving a speech and was recognized by the University Board of Regents with a special honor. Bollinger said he plans to attend many of the events in Stockholm including a lecture by Veltman scheduled for tomorrow along with a banquet to be held Thursday in Veltman and t'Hooft's honor by the Dutch Ambassador to Sweden. On Friday, Bollinger said he is planning to attend the Nobel Prize ceremony at the Stockholm Concert House and a reception to be held at Stockholm's City Hall.

Hi everybody: From time to time (particularly during the early years of EMF-L), we have talked about the ultimate "mechanism" that results in bioeffects from EMF; the "disturbance" or the "coupling" that takes place at the most minute level the impact of the electrons of the atoms and molecules (from the EMF exposure) upon the electrons of the cells and tissue of life. In the news item below, announcing the latest Nobel Prize winners, whose research has contributed to "proving" the universal theory of the universe that all energy and matter are one, fundamentally you will see that: what we think of as a chemistry process (the bioeffects of EMF) ... is actually a process common to the natural electromagnetic behavior of the universe. That is the process these Nobel Prize winning scientists have been looking at in their experiments. If we can understand what they are doing, it should not be so difficult for all of us to understand that: what they are "looking at" is the very same phenomenon that results in EMF disturbances of the electrons of the atoms and molecules of our cells and tissue ... causing (in some cases) chemical reactions which produce 'abnormal' behavior of our cells and tissue, resulting in various illnesses.....

1999 Nobel Prize 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.

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
