Re: 1213: "Combination Vision"

I don't have synesthesia but I could still immediately see the 2. I vaguely see the 2 as well, but I think it's just the characteristics of the number 2. 4 can be, and is, drawn with straight lines. 2 has curves, and the digits seem to both be clumped up and smaller in the curves, making them stand...

Script that adds the Forums link back to XKCD's home page

I'm not sure why this link has been added and removed from the page several times, but I prefer it to be there. To that end, here's a user script that will add it back: http://userscripts.org/scripts/show/153686 It works on Firefox (with GreaseMonkey add-in), Chrome and Opera, but those are the only...

Re: 0979: "Wisdom of the Ancients"

I am the one who necros these threads and answers them even when they're almost ten years old once I finally find the answer.

You're welcome.

Re: 0844: "Good Code"

Randall finally mentions Android. The trouble is, being non technical, I don't know where Android is supposed to be on that flow chart. Having sold the phones and seen how well they've worked (Esp. the ones by Motorola and HTC) I'm inclined to think that it's under "Code well" and "G...

Re: 0818: "Illness"

Best wishes to you and your family. Suggestion: Instead of flash games you could distract yourself trying to prove the Riemann hypothesis. I suspect that more than a few mathematicians have lost more hours than they care to admit to that pursuit. Of course, if physics is more where your mind is at t...

Re: 0806: Tech Support

I was once having difficulties staying online with my cable Internet connection. I use a Linux system as a NAT (two NICs) and have done so for many years. I called tech support: Me: I'm having trouble staying connected. The cable modem works fine, but every couple of days I just lose connection alto...

Re: Can't Appreciate the Unknown

Well, 16 certainly sounds quite old to begin trig - I'm 15 and doing integration. Anyway, more advanced trig is fun, vectors are definitely not fun (long, exhausting, hard to set up, and the actual math, the fun part, is easy), matrices are interesting, binomials are very nice, game theory is great...

Re: Significant Figures

To get the correct answer you should not round in any of your calculations. Some teachers (and some exam mark schemes) don't know this, so god knows what you'll have to to actually get marks, but finding out shouldn't be too hard. This is exactly how I felt about it, and you're right, I can't tell ...

Re: Largest number on Twitter

Without any given rules, I submit: ((((z^z)^z)z)^z)^z... In base 37. Now, because an arbitrary base of any size can be chosen and a number designed to fill it then we could say that we can represent the largest number this way by numbering every character/glyph in the unicode character set sequentia...

Re: Significant Figures

Significant figure "rules" only apply in operations with measurements whose precisions are not explicitly given, as a rough way of preserving the amount of uncertainty in the problem. So it has no place in math class. Right, I should have been more clear, we're referring to a physics lab....

Significant Figures

Fellow math geeks, I had another student ask me a question today about why I included more digits from the result of a division operation than significant figures rules indicate. I answered that, because that number was going into further calculations, those digits do add precision to the result wit...

Re: "Academia vs. Business" Discussion

You have beautifully summed up in one short comic exactly why it is that I don't program professionally anymore. Thank you for that. ;)

Re: "Two-Party System" Discussion

I'm really amazed that there's a forum on the internet where the politics discussion doesn't turn into a flame war in the first three posts. Is it because so many of us who regularly read (and actually understand) this comic are assorted science/math/etc. nuts? It makes me chuckle that the topic dev...

Re: Domain of a function.

Your instructor is right, of course. If the domain of sqrt is the nonnegative reals, then (\sqrt{-1})^2 doesn't mean anything. I do agree, given the constant -1 and the restriction of sqrt to the real domain. Where I tend to take issue with it is in the formulaic reduction prior to solution...

Domain of a function.

Hello, all. This is my first post here! I've followed the comic for a while, and occasionnaly the fun stuff on the forums too. I have a question I'd like to put to you fellow math geeks. I have a class which (for the time being) is pretending that the complex plane doesn't exist (maybe some of the s...
