Losing the Nobel Prize
In this special edition, physicist Brian Keating discusses his new book, which recounts the ill-fated BICEP2 announcement--and retraction--of the claimed discovery of primordial gravitational waves in 2014. Keating talks to Zeeya about some of the questionable ethical choices that led the team to the wrong conclusions, the problems with peer review and media hype, and how he thinks the Nobel Prize should be reformed.

Continuing with the differentiation of what is observed or seen and what is the observer independent phenomenon; "colour" could be helpfully reserved for products of processing EM input. Which are correlated to wavelength but not directly corresponding. As the colour product also depends on the processing that occurs, the chemistry of the photo-receptors or senors or sensitive material used, and how the light is being received , I.e. the relationship of the observer to the EM input. The EM waves...

I think it would be helpful, in physics, to use the words "light" and "electromagnetic radiation" or" EM waves", and the like, to represent categorically different phenomena. "Light " for the product of processing of received EM radiation; and "EM radiation" and the like. for the phenomenon in the environment which might be input to an organism sensory system or a sensitive device.

Dear Georgina,

Light does not have a surface. Only one single unified infinite surface eternally occurring in one single infinite dimension that am always mostly illuminated by FINITE non-surface light has ever existed and will only ever exist. You are trying to describe a finite amount of one single light source that could only be finitely OBSERVED by one finite observer .
