F. J. Duarte Quotes (1954-)

“Regardless of the prophetic value of Dirac’s description [on interference] his was probably the first discussion... including a coherent beam of light. In other words, Dirac wrote the first chapter in laser optics.”

“Regardless of the prophetic value of Dirac’s description [on interference] his was probably the first discussion... including a coherent beam of light. In other words, Dirac wrote the first chapter in laser optics.”

“All the indistinguishable photons illuminate the array of N slits, or grating, simultaneously. If only one photon propagates, at any given time, then that individual photon illuminates the whole array of N slits simultaneously.”

“I was enlightened by some long conversations with Dick Dalitz, a particle physicist, who himself was a giant of Australian physics known for the Dalitz plot and the Dalitz pair.”

“Regardless of the prophetic value of Dirac’s description [on interference] his was probably the first discussion... including a coherent beam of light. In other words, Dirac wrote the first chapter in laser optics.”

“A gifted experimentalist, and theoretician, in the best Newtonian tradition... His contributions to quantum measurements, and elucidative teachings on quantum mechanics, have not yet received the attention they deserve.”

“Multiple-prism arrays were first introduced by Newton (1704) in his book Opticks. In that visionary volume Newton reported on arrays of nearly isosceles prisms in additive and compensating configurations to control the propagation path and the dispersion of light. Further, he also illustrated slight beam expansion in a single isosceles prism.”

“Feynman uses Dirac's notation to describe the quantum mechanics of stimulated emission. ... He applies that physics to several physical systems, including dye molecules. ... In this regard, Feynman could have predicted the existence of the tunable laser. Furthermore, Feynman made accessible Dirac's quantum notation via his thought experiments on two-slit interference with electrons.”

“In the same style as Dirac, who wrote: “the interpretation of quantum mechanics has been dealt with by many authors, and I do not want to discuss it here. I want to deal with more fundamental things”, Ward was not interested on issues of interpretation... According to Shakarov, Ward was one of the “titans” of quantum electrodynamics alongside Dyson, Feynman, Schwinger, and Tomonaga. Thus, his non interest on issues of interpretation should not be dismissed lightly.”

“One of Ward's few close friends at Macquarie is... Frank Duarte... the two make an odd couple - the restrained rather distant Englishman and the intense, earnest South American.”

“Ward was vocal in his denunciation of the trivia that filled up Senate agendas… suitably then, it was a close student associate of Ward’s, physics Ph. D. student Frank Duarte, who began to mobilize student opinion in favor of a change.”

“The sciences revolted under the guidance of several student activists, Frank Duarte in particular... we were fortunate that Duarte somehow established close links to the Federal Government, which was now the source of all funds.”

“Another connection with Newton's pioneering work on spectra has been found by Duarte in modern quantum optics.”
