   frequency can be used to measure things that really feel like they should use different units.

   "how often should my OS check the state of the keyboard"

   "middle C"

   this is technically a coherent answer

     @lily Well I guess C would be happy to cast it, different named type but same underlying types. :D

     one problem of this is it could be confused for transistor size

     @lily you could get sillier and give your cpu cycles in terms of clock wavelengths. this is a 7.5cm CPU connected to 22cm RAM. actually i imagine a variation of this is somewhat useful for circuit design

     @astrid @lily Ultraviolet CPU seems quite powerful, after all ~2Ghz is microwave (inb4 your CPU clock could mess with wlan/bluetooth).

     @astrid @lily the *amount of people* that think A4 paper is in the golden ratio is maddening. there is more than one interesting number! A4 is in √2, not ϕ! Although whatever you do don't tell the designers that or they'll be calling it "tritone paper" and insisting it's cursed

     @andrewt @lily I hate everyone's obsession with the golden ratio so much. It's an interesting number mathematically but for literally none of the reasons anyone thinks it's interesting. They'll go impose a spiral or ratio onto literally anything, it won't even be aligned, there's enough tolerance that they can get away with it, and they're like "wow cool universal constant" when no, you're just doing designerist numerology

     @astrid @lily also "minor seventh" is also the name of a chord so I assumed we were using the ratios of all the notes in that chord and it sounded very silly but no, they're doing a perfectly reasonable thing and just *calling* it something silly

     @andrewt @lily see this would only somewhat work if 2x the font size had some significant meaning. like 2x the frequency does, but 2x the font size doesn't really? and it would work better if there were harmonics and beats between specific intervals but there aren't either? like it's not even a good analogy

     @astrid @lily it really isn't. Not least because they'll never get to the ×2 interval because their minor third isn't ⁴√2, it's 1.2, so stacking four of them will give you ×2.0736. And one of their favourite intervals is ϕ — the whole point of musical intervals is to be (or approximate) neat, simple ratios and the whole point of ϕ is to be as far away from any of those as it can. It's arguably the most violent possible discord you can produce with two notes. It's not just a pointless analogy, it's actually *fighting* them.

     @astrid @lily ok but bloody web designers actually do this shit

     they say shit like "our website is designed around a minor third interval" to mean that headers are 20% bigger than body text and just please shut the hell up, no, first of all that's a preposterous thing to do and second of all you haven't defined if you mean an just intonation minor third or an equal temprement minor third because if you've designed the whole thing around the fourth root of two then your devs are going to at best ignore it and at worst murder you

     @astrid @lily @andrewt What I particularly like is /why/ people get all golden ratio on music (*):

     An octave has: Five black notes. Eight white notes. Thirteen notes. 5, 8, 13, Fibonacci, Φ!

     Unfortunately, the 8 and 13 double count the first/last note, and it's really about the twelfth root of two.

     So you've got a whole branch of musical numerology based on incorrect 1-based indexing!

     ((*) Sorry, Andrew, if this is what you were referring to, but I didn't see it explicitly mentioned.)

     @andrewt e.g. https://www.goldennumber.net/music/ ! It's one of those things that just gets repeated around by people who don't really get the maths.

     To be fair, "black and white notes" are more accurately 8 notes in a tonal scale (really 7), selected from 13 notes (really 12) in the octave. "Black and white" is just explaining that in the context of C major.

     @sgf @astrid @lily oh my god what, no, i've never heard of this nonsense? what the hell?

     like half of all the one-digit integers are Fibonnaci numbers

     0 ✅ sort of
     1 ✅✅
     2 ✅
     3 ✅
     4 ❌
     5 ✅
     6 ❌
     7 ❌
     8 ✅
     9 ❌

     it's hardly a surprise that the 5 and the 8 hit, and the 13 is just those added together so that one's free

     and that's assuming you count from C. what if you're playing in C#? Then an octave has six black notes and seven white notes, those aren't Fibonacci numbers! there are three non-fibonacci numbers lower than 9 and you've hit two of them.

     why do all the maths cranks focus purely on ϕ and cantor's diagonalisation theroem
