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.
Duarte quotes
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.
Duarte
Personally, I find the concept of a "final theory," or a "theory of everything" rather limiting. The fun of discovery will most likely last as long as the human race continues.




Duarte F. J. quotes
Feynman uses Dirac's notation to describe the quantum mechanics of stimulated emission... he applies that physics to... dye molecules... In this regard, Feynman could have predicted the existence of the tunable laser.
Duarte F. J.
After some algebra, a successive formula can be derived from Duarte's original equation.
F. J. Duarte quotes
The Dirac notation, though originally applied to the propagation of single particles, also applies to describing the propagation of ensembles of coherent, or indistinguishable, photons.
F. J. Duarte
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.
Duarte F. J. quotes
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.
Duarte
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.
Duarte F. J.
In 1994, Duarte first reported on solid-state dye laser oscillators.
F. J. Duarte
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.




F. J. Duarte quotes
The intimate relation between interference and diffraction has its origin in the interference equation itself.
