Frases de David Gross

David Jonathan Gross é um físico e teórico de cordas estadunidense.

Juntamente com Frank Wilczek e David Politzer, foi galardoado com o Nobel de Física de 2004, pela sua descoberta da liberdade assintótica.

Gross bacharelou-se e fez o mestrado na Universidade Hebraica de Jerusalém, em Israel, em 1962. Recebeu o seu Ph.D. em física pela Universidade da Califórnia, Berkeley em 1966 e foi um Junior Fellow na Universidade de Harvard e Professor na Universidade de Princeton até 1997. Ele também foi um dos que assinaram uma petição para o presidente Barack Obama em 2015 para que o Governo Federal dos Estados Unidos fizesse um pacto de desarmamento nuclear e de não-agressão.

David Gross: Frases em inglês

“Why is space-time doomed? There are many reasons, among which: In string theory we can change the dimension of space-time by changing the strength of the string force. Thus, the so-called II-A string theory, which semi-classically describes closed strings moving in ten-dimensional flat space for very weak coupling is dual for strong coupling to a theory, called M-theory, that at low energies is described by eleven-dimensional supergravity. By increasing the string coupling we can grow an extra dimension. How can the spatial continuum be fundamental if the number of spatial dimensions can be so changed?”

“Physics is always a gamble; it is a game of exploration. That’s the fun of it. We never know for sure what will happen. Sometimes, we theorists can anticipate, but nature is the final judge.”

“Remarkably, the building of the Standard Model — the theory of how particles and forces interact — was the success of the conservatives. It required no revolution at the foundational level. Normal physics, the kind that goes on experiment after experiment, produced the Standard Model.”

“String theory was not invented to describe gravity; instead it originated in an attempt to describe the strong interactions, wherein mesons can be thought of as open strings with quarks at their ends. The fact that the theory automatically described closed strings as well, and that closed strings invariably produced gravitons and gravity, and that the resulting quantum theory of gravity was finite and consistent is one of the most appealing aspects of the theory.”

“The universe has been expanding since the big bang, thus early on it was hot and dense. To trace the history of the universe we must understand the dynamics that operates when the universe was hot and particles were very energetic. Before the standard model we could not go back further than 200,000 years after the big bang. Today, especially since QCD simplifies at high energy, we can extrapolate to very eary times, where nucleons melt and quarks and gluons are liberated to form a quark-gluon plasma.”

“… From the age of 13, I was attracted to physics and mathematics. My interest in these subjects derived mostly from popular science books that I read avidly. Early on I was fascinated by theoretical physics and determined to become a theoretical physicist. I had no real idea what that meant, but it seemed incredibly exciting to spend one's life attempting to find the secrets of the universe by using one's mind.”
