Can I get aleph-null aleph-shaped throwing stars? LunarNapolean (talk) 20:18, 7 August 2020 (UTC)

Apologies to whoever added the "citation needed" that I stepped on. -- brad

That zeta looks conspicuously bad. I wonder if this comic will get a cleaned-up version uploaded. 108.162.237.16 20:51, 7 August 2020 (UTC)

Megan usually has shoulder-length hair, so the person being attacked by Ponytail is probably not Megan... except in so far as all brunettes in this comic are called 'Megan'. LtPowers (talk) 20:53, 7 August 2020 (UTC)

Is one of them Danish? And one of them Megan? 172.69.33.121 22:49, 7 August 2020 (UTC)

I think Randall is underestimating the weapon utility of psi. There's a real-world martial arts weapon that looks somewhat like it.172.69.68.197 22:04, 7 August 2020 (UTC)

I think he’s also seriously underestimating the value of keeping your fingers attached to your hand. Swords have guards for a reason. I’d pick the contour integral over anything else there.

Considering the title text, a bass clef looks pretty formidable, close to a bat'leth. Nutster (talk) 00:31, 8 August 2020 (UTC)

Yes, but the treble clef is the one in the title text, and that’s nothing like a Klingon bat'leth. I removed the comment from the table. Adam1729 (talk) 02:09, 8 August 2020 (UTC)

These “weapons” seem strangely appropriate for xkcd’s stick figures... -cpl

Are we sure White Hat is holding empty set? There don't appear to be points extending outside the circle in which case I think he's actually holding Theta -jc

Can I use the LaTeX mathwitch? 141.101.98.26 10:03, 8 August 2020 (UTC)

First time editor here,hope I get the notation right! Question on the pi link to wikipedia: I put in the double link to the main page and the disambiguation because unfortunately https://en.wikipedia.org/wiki/Pi_(disambiguation)#Mathematics doesn't include the mathematical constant definition (though it is listed at the top of the page). Thoughts? Alan g (talk) 10:38, 8 August 2020 (UTC)

I think that’s the is proportional to” symbol rather than just alpha. They are similar but have different Unicode symbols. Thoughts?--141.101.98.222 12:01, 8 August 2020 (UTC)

You're definitely correct. (They don't even look that similar...) It's the direct proportion symbol, not the symbol for Alpha.
