Was it because there were so much more interesting things I wanted to understand than to communicate with people? I was thrilled to notice that the tree trunks grow along the lines of gravity and ignore the direction of the slope. Much of those are essential ingredients of theories in
I passed easily the first round; only by being nervous I had misread the first exercise, which had been done correctly by most other participants. She taught me Beethoven, Chopin, Debussy, Mendelssohn and many others. As he was one of the organizers of an international conference on particle physics at Amsterdam in 1971, he decided to use his new pawn (me) in his battle for the recognition of Yang-Mills theories, and gave me 10 minutes (but no place in the Proceedings) to explain our new results.
Gell-Mann-L�vy sigma model for pions and nuclei. But I managed, and now I am happy that I can communicate with the inhabitants of a major fraction of Europe.So much easier were math (of which there was surprisingly much: algebra, analysis, trigonometry, stereometry), physics and chemistry. I was coxswain in their celebrated Rowing Club, Triton, where I was appreciated because I could keep their boats coasting in straight lines. For PH.D Thesis work in 1971, Nobel Prize awarded in 1999. please refrain from mailing to me your alternative theories until you have
The monsters had to be fed with paper cards in which you had to punch your programs. determinant, Slavnov identities, BRST symmetry. Spontaneous symmetry breaking could not be the resolution of the Yang-Mills problem because such massless particles do not exist. I vaguely remembered the text in the book, and tried to reproduce it. You can make one wheel turn by rotating the other. “Most people first do this wrong”, she said. The principle of transmission. I could not understand why none of the expert theoreticians would embrace quantum field theories for quarks. But more often than not, my uncle invited me in, and I adored the discussions, and the laughter.The student organization forced me to spend time also on other things besides physics, which was exactly why my father had wanted me to become a member. Goldstone mode, Higgs mechanism.
You would be able to go into the tiniest spaces between the pebbles, and those would be as big as houses for you. Although it was known that perturbative In the 1980s, 't Hooft's attention was drawn to the subject of gravity in 3 spacetime dimensions. He is married to Albertha Schik (Betteke) and has two daughters, Saskia and Ellen. But I had never stopped thinking about physics, and I could begin my PhD studies in 1969. He used to talk of the giants “Maasdam” and “Rijndam” as his ships. that (s)he would never master this in 5 years; indeed, I am addressing
My grade for it was superb.I had the good fortune of having an enthusiastic art teacher. university degree?" "...You sketch the path for potential students through the forest of
The concept of renormalization is introduced. lecture courses. His grandmother was a sister of Nobel prize laureate Frits Zernike, and was married to Pieter Nicolaas van Kampen, who was a well-known professor of zoology at Leiden University. 't Hooft has "deviating views on the physical The story goes that Lévy had looked up in the atlas which French town has the maximal amount of sunshine during summer, and then he found this location. He gave me the choice between various topics, but none could catch my imagination more than the subject he himself was working on: the renormalization of Yang-Mills fields. I learned the answers to all these questions.Of the modern languages, English, French and German, besides Dutch, were obligatory. This was a subject in which Veltman was involved. We were on a vacation in the hills in the south-east of Belgium.
The generally accepted name for these identities would be the “Slavnov-Taylor identities”.After having learned so much about renormalizing massless Yang-Mills fields, doing the same thing for theories with Higgs mechanism was relatively easy. these authors were not so stupid after all. At least at this point I could agree with my advisor, Veltman. All these fields were associated to spinning particles with mass.
I ignored his sensible advice. Finally, there was the scaling problem. supernovae); cosmology (cosmological models, inflationary universe theories,
She was tough. In earlier days the cellar had probably been in use by prostitutes. The day before she was to meet her new superiors and colleagues there, we had made a trip to the Mont Blanc; on the way back we were in a minor car accident, and she fractured a bone in her foot.
When I returned to Utrecht, his assignment to me was that I should first study the pure Yang-Mills system, without anything resembling a Higgs mechanism for generating masses. “It never came up”, she now says, adding that actually math and science were not particularly difficult for her at school, but being a girl, you wouldn’t admit that you actually liked such subjects. The concept of renormalization is introduced. I had seen how supersymmetry was born, back at CERN during the early 1970s. “You know, Gerard”, a schoolmate had once said to me, “nobody in the world understands how a radio works”. The Nobel Prize in Physics 1999 was awarded jointly to Gerardus 't Hooft and Martinus J.G.
