Frases de John Carlos Baez

John Carlos Baez é um físico matemático americano, conhecido por seu trabalho em spin foams e gravidade quântica em loops. Mais recentemente, sua pesquisa tem focado na aplicação da teoria das categorias à física.

No entanto, Baez é sem dúvida mais conhecido pelos habitantes da Usenet como o autor da coluna This Week's Finds in Mathematical Physics . Iniciada em 1993, essa irregular série de posts, mostrando uma mistura imprevisível mas muitas vezes fascinante de boatos, excelente exposição, bravatas intelectuais, algumas vezes críticas ferozes e as réplicas que se seguem, ganhou admiradores devotos em todo o mundo . Baez também é conhecido na Web como o autor do índice crackpot.

Baez ganhou seu Ph.D. no MIT em 1986, sob a direção de Irving Segal. Ele conseguiu traçar sua genealogia matemática diretamente até ninguém menos que o Príncipe da Matemática: Carl Friedrich Gauss.

John Carlos Baez: Frases em inglês

“Quantum theory may be formulated using Hilbert spaces over any of the three associative normed division algebras: the real numbers, the complex numbers and the quaternions. Indeed, these three choices appear naturally in a number of axiomatic approaches. However, there are internal problems with real or quaternionic quantum theory. Here we argue that these problems can be resolved if we treat real, complex and quaternionic quantum theory as part of a unified structure. Dyson called this structure the "three-fold way"…. This three-fold classification sheds light on the physics of time reversal symmetry, and it already plays an important role in particle physics.”

“The most popular approach to quantum gravity is string theory. Despite decades of hard work by many very smart people, it's far from clear that this theory is successful. It's made no predictions that have been confirmed by experiment. In fact, it's made few predictions that we have any hope of testing anytime soon! Finding certain sorts of particles at the big new particle accelerator near Geneva would count as partial confirmation, but string theory says very little about the details of what we should expect. In fact, thanks to the vast "landscape" of string theory models that researchers are uncovering, it keeps getting harder to squeeze specific predictions out of this theory.”

“Besides their possible role in physics, the octonions are important because they tie together some algebraic structures that otherwise appear as isolated and inexplicable exceptions.”
