∅ (empty set)
How it feels to be autistic navigating social rules.
Ø - The Norwegian umlaut version of O.
⌀
U+2300 DIAMETER SIGNActually æ, ø, and å are regarded as separate letters in the Norwegian alphabet
Æ - like the a in cat
Ø - like the u in turn
Å- like the aw in paw
Here's a handy song about it
Øh nø
You mean like the German Ö?
This is why, as a Norwegian programmer, I slash my 0s with a backlash and my Øs with a forward slash.
Oh eh... Kunne du bruke det ikke i navnet ditt eller?
We also use that to designate phasing in the electrical world.
Ahhh ahhhh ahhhhhhhhh I hate it
Whyyyy does humanity do this to itself

The slashed zero is the empty set, and the slashed O is literally nothing cause screw the slashed O
All my guys love the Ø! We Even have the Ååhh. Jut let me know if that makes you Æææh!

I was hoping it was gonna be that video! One of the few times I will agree that size matters.
Empty set is ∅, slashed zero is 0︀ (if your browser decides to render the unicode variant) or 0︀ in html
Learn the difference, it could save your life!
(It could not actually save your life)
My genuine reaction to that information:
∅, with a slash through it!!!
Sø I shøuld slash all my Øs sø they can be distinguished from 0. Gøt it.
Including the majestic møøse
Dad was a programmer on IBM 700/7000 series. He always slashed the letter O. Years later in programming people were slashing zeroes and I was mighty confused. Some greybeard explained it eventually.

As someone who slashes their zeroes, ouch.
Well it was someone else who spent most of their career with FØRTRAN punchcards. By the time I was learning BASIC in the 1980s it had moved to the zero.
/0
edit: what was that meant to do
When your language and numerical project managers don't talk to each other
disambigruleation
Not the empty set?
It gets better

"The slash as a designator! Why that is brilliant..." - Dr.Klein
Ø is an album by Underoath
And a damn good one
Hø?
Is that a compromise solution for the age old H0 vs HO debate?
That makes sense I guess.
Hmmm. There's room for a slash from the top left to bottom right to disambiguate this, but it'll likely end up with more slashed Os and 0s.
⦰ is a reversed empty set.
Also great: 𝟶
Ah yes, the full set
