It's so wild to have a whole paper about this... that's also LLM written. What are we even doing here?

The whole thing is unbelievable slop ! I think the whole article is llm-generated unfortunately (just reading the first paragraph I got an immediate smell).

ha, thank you! it's very fun to write these hopefully you also enjoy the next one which imo makes a fun connection between the linear algebraic CRT and the fourier transform :)

yes, definitely some of it is (purposefully) fast and loose, though (ideally!) mostly unambiguous with reasonable assumptions I think that part should've been "vector subspaces" rather than vector spaces since that is how U a

Fair on all accounts! Surely, this could be made way more lively if I were in front of a blackboard waving my hands and drawing images, but alas, the medium is what it is :) Thanks for reading though!

well, the statement is: is there a single operation, built from elementary operations, such that all _other_ elementary operations have finite representations. this preprint answers that in the affirmative otoh, (x, y) -> 1/(x-y) do

I think the point is that it is _finite_. if you allow infinite expressions then the basic monomial basis or quotients thereof are “even simpler”

I don't think this can do any of the "standard" constants or what we generally consider to be closed-form expressions, though ! (E.g., no e, pi, exp, log, etc.)

yeah it’s slop; multiple sites also confirm this, seems like they are using clawdbot or whatever

> few of the computable numbers that are not algebraic are interesting, the main exceptions being the numbers that are algebraic expressions containing "2*Pi" and/or "ln 2". I don’t think this is true at all. For

I don't want to put OP on blast here, but this is unfortunately just complete slop writing. The points being made are fine, I think, but look, if it's faster for you to generate than it is for us to read, I think this qualifies as

Sweet thanks! Yes definitely a great extension would be to add a camera in the image plane (alternatively, defocusing the image slightly and using a photodiode would also be fun!)

it is thoroughly _fine_ advice stated in a shitty way that misses the entire point of this cheap demo

by LolWolf 9mo ago
ah very cool, I see! good luck! are you posting updates anywhere?
25.
by LolWolf 9mo ago
sure ! I’ll give it a try a little later once I’m at a computer ! (you can too, if you’d like, the CAD files are all online as .step files :)

Ooh, great question. Usually fractions (~1/20th?) of a turn for alignment, it’s hard to go below that since the mounts are so small and the springs don’t have the tension to keep it super stable. (This is plenty for such a “coarse” set

I think getting an electron source and creating a robust-ish adjustable set up is v doable, but is definitely more of a Real Project(TM) than this silly little interferometer :)

I think that’s very much right :)

I see, what’s the min step size you’re going for?

i’d probably just get it milled only if you had the CNC handy, the complexity isn’t enough to justify 3d printing it in metal (probably a decent bit more expensive too!) but at “get it done in JLCCNC” prices I think a thorlabs mount is prob
