Old comments??

The claim that light is not subject to gravity is incorrect. The discussion following this claim will therefore require a better justification.

Atom not atomic.
@Nerd271 Sorry but I reverted the change of Atom -> Atomic. Even the reference you added calls it Atom: "Atom Wave Interferometry with Diffraction Gratings of Light". I know it seems logical but that is not the terminology used.

Also the laser beam aspect belongs in the body rather that the first sentence. Atom interference predates lasers. Johnjbarton (talk) 14:29, 12 August 2023 (UTC)


 * But some other sources that I have consulted, including Hecht's Optics and the McGraw-Hill Encyclopedia of Science and Technology use "atomic" instead. Atomic interferometry today uses lasers, as Hecht explains. This is a well-known textbook. I will restore this bit. Nerd271 (talk) 22:15, 12 August 2023 (UTC)


 * I think the lead should be very concise, very focused, with just essential information about the interferometry using atoms. Then ideally the rest acts like summary of the article.
 * In that spirit I think the information that other sources use "Atomic" belongs in the lead paragraph. Sorry I didn't realize that Hecht used "atomic" since your ref used "atom". (I would appreciate the page number in Hecht if possible, I couldn't find his discussion).
 * The laser bit however seems like an important detail. One could say "Atoms are manipulated in vacuum chambers" or any number of other observations related to the mechanism of these experiments. Vacuum chamber are actually required, but lasers are an issue of practically. Thus to me the sentence on lasers looks stuck in.
 * If we had a section laser cooling applied to atoms for interferometry, then a sentence in the lead would be great. Can we do that? Johnjbarton (talk) 22:37, 12 August 2023 (UTC)


 * The reference to Hecht's book includes page numbers; they are 420-1.
 * Please include a section detailing the use of lasers. Nerd271 (talk) 12:29, 13 August 2023 (UTC)
