Hamilton had experienced at Brougham Bridge
William Rowan Hamilton (1805-1865)was an Irish mathematician, physicist, and astronomer who made important contributions to the development of optics, dynamics, and algebra. His discovery of quaternions is perhaps his best known investigation.
The discovery of quaternions reportedly occurred during a walk with his wife by the Royal Canal in Dublin. Upon having the inspiration for the formula, he promptly carved it into the bricks on the side of the canal. Wikipedia entry

blindness at the heart of a diamond
This enigmatic imagery is reflected (no pun intended) in a few references:
"where the light came down sifted through so many emerald screens that it was as flawless as the heart of a diamond. " (Anne of Green Gables, Chapt. 15, by Lucy Maud Montgomery)
"It was a singularly sharp night, and clear as the heart of a diamond." A Story that is Untrue by Ambrose Bierce

Nernst lamps
An early incandescent lamp invented by Hermann Nernst, which made use of a heated ceramic rod to produce light in ambient air (in contrast to Edison's incandescent, which required a vacuum to operate).
Hermann Nernst was also responsible for first formulating the Third Law of Thermodynamics, also called the Nernst Heat Theorem. "Nernst Heat Theorem (Third Law of Thermodynamics) was presented by Walther Nernst on December 23, 1905 at a meeting of the Königliche Gesellschaft der Wissenschaften zu Göttingen."
Etienne-Louis Malus
1775-1812, a French officer and mathematician whose work was predominantly concerned with light. He studied ray systems, and his theory on polarisation was published in 1809. His theory of the double refraction of light in crystals was published in 1810. Wikipedia
Malus is also the genus of the apple.

my harmless little intraterrestrial scherzo
Once again, the unseen narrator appears. By inference, the narrator is also the author of the various Chums of Chance... books referenced in ATD.
