" The fundamental idea of 1924 thesis was the following: The fact that, following Einstein's introduction of photons in light waves, one knew that light contains particles which are concentrations of energy incorporated into the wave, suggests that all particles, like the electron, must be transported by a wave into which it is incorporated ... My essential idea was to extend to all particles the coexistence of waves and particles discovered by Einstein in 1905 in the case of light and photons.

A study published in May 2010 suggests that the blue light often used for SAD treatment should perhaps be replaced by green or white illumination.

Special relativity suggests that the concept of simultaneity is not universal: according to the relativity of simultaneity, observers in different frames of reference can have different perceptions of whether a given pair of events happened at the same time or at different times, with there being no physical basis for preferring one frame's judgments over another's ( though in a case where one event A happens in the past light cone of another event B, all frames will agree that A happened in the past of B ).

In writing to George Devine, who directed the Old Vic production, Beckett suggests that “ the inquirer ( light ) begins to emerge as no less a victim of his inquiry than they and as needing to be free, within narrow limits, literally to act the part, i. e. to vary only slightly his speeds and intensities .” But the role of the light is even more ambiguous, for it has also been seen as “ a metaphor for our attention ( relentless, all-consuming, whimsical )” and a way of “ switching on and switching off speech exactly as a playwright does when he moves from one line of dialogue on his page to the next .” Neither of these analogies conflicts with the more popular views where the spotlight is believed by to represent God, or some other moral agent tasked with assessing, each character's case to be relieved from the binds of the urn by having them relive this relationship, which has ruined all their lives.

The video signal is amplified and then switched, in synchronism with the three ultraviolet light sources which are sequenced by the rotating mirror so that during one-twentieth of a second only one wavelength, corresponding to red, green, or blue, is seen.

( Note: Because of light leakage from one ultraviolet source to another, the lights are switched by a commutator-like assembly rotated by a synchronous motor.
