in addition to the answers above, I also think that many people who read webcomics (which are usually found online[citation needed]) expect there to be an online forum for most webcomics. I know I do, after years on this forum; I imagine many of those of the lucky 10,000 who are just discovering xkcd after following other webcomics are in a similar boat.

Somethings I think the imaginary constant is a mistake. Instead of inventing a constant to satisfy the equation, look at x2 + 1 = 0 as an eigenvalue problem, and find the 2x2 matrix

Code: Select all

0 -1
1  0


Also known as the 90 degree 2D rotation matrix.

Exactly. I think the only problem with imaginary numbers is the name. If they were given a more sensible name, I feel like people wouldn't have such a proclivity to question them. You'd just note that, yes, multiplication by i gives a 90 degree rotation in the complex plane.

In fact, I believe the phrase "imaginary number" first arose as a derogatory term used by some mathematician (Descartes, maybe?) who I suppose didn't see the point of these new-fangled numbers that didn't lie on the real line.

So, I shave with a straight razor that uses disposable blades, and I haven't replaced my last sharps box yet, so like a moron I left my last used razor on my sink. Apparently sometime between then and today I set a bar of soap down on top of the razor. You can probably guess what happened when I went to wash my hands. Yep, dirty razor jammed right into the palm of my hand. That was fun. I guess I'll be going to urgent care tomorrow to see if they think a tetanus shot is needed.

Urgh, that sounds unpleasant. Is it one of those straights that uses half a DE blade, or one of the dovo ones that uses long blades? If it's the DE blade sort an alternative to getting a new sharps box would be to change to Feather, Derby extra, or Merkur brand blades. Those brands all come packaged in a sturdy little plastic box, with integrated storage for the used blades. For me Feather work the best, at least in a DE safety razor, but they are stupidly sharp - don't buy them if you don't want utterly ridiculous sharpness, Derby are nice and smooth but not as sharp, and Merkur are horrible.

Edit: I suppose if you were being really safety conscious you would still chuck the plastic box in a sharps bin, but I figure that the box is going to be sitting there solid in the landfill site long after the blades have rusted to nothing. Maybe I shouldn't do that?

Yea, it's the half-DE kind. I usually switch between Shark Saloons and Derby Professionals. I've never known Derby's to come with a disposal, but I'll check it out. I've already ordered a new sharps box though, it was 5 bucks and it lasts me a long, long time, so I'm not too torn up about it. Except my hand :P

FWIW, bacteria doesn't survive as well on metal as it does on organic surfaces. Also, you're much less likely to get tetanus from a razor on the side of your sink than from a rusty nail in the dirt ("dirt" being the important part, not "rusty").

If you haven't had a tetanus shot in the last ten years, though, you should probably go get one in the next couple of days. It's a good thing to keep up to date. The incidence is fairly rare, but you do NOT want to be one of the 0.x% that get it.

Perhaps, but ℂ is somewhat easier to work with than M(2, ℝ). Especially for complex matrices -- matrices whose elements are also matrices are nasty if you need to work with them in explicit form. I'll stick with ℂ for the time being.

Good to know. Went to the urgent care and the doc gave me a T-DAP shot, since I couldn't remember the last time I had a tetanus shot. So now I'm guess I'm good against diphtheria and whooping cough too. Because apparently whooping cough is tearing through the adult population of the south. I didn't realize adults got whooping cough, I thought it was a baby thing.

If it's the simplest/most elegant way to do it, then go ahead, but I don't think using 2x2 matrices instead of complex numbers is in any way beneficial -- beyond perhaps getting people into the mindset of "thinking with matrices", which is of course a valuable skill (that even led to the Dirac equation).

Though, thinking more about it, you could represent complex numbers in terms of basis matrices u and v, at which point you can define the notation a+bi to be equivalent to au+bv, at which point you've recovered the standard complex notation, which can then be used as a shorthand for the underlying 2x2 matrices. ;)

Agreed. I've often thought "lateral numbers" would be a less misleading term. FWIW, I was able to explain complex numbers to my 9 year old nephew (who loves maths) by calling multiples of i "sideways numbers".

Each forum has a flag for whether the posts in that forum get added to active_topics. For a time, phpBB was set up so that the default for new forums was for that flag to be turned off, but there was a bug and the flag was ignored... then, later, there was a bugfix that changed it so that the flag defaulted to turned on, and actually worked.

The net result is that forums created before the bugfix happened (ie: most of them) aren't in active_topics, but those created afterwards (ie: Fictional Science) are. What If? also doesn't show up there, even though it was created later, I guess the flag was explicitly turned off? My guess is that whoever created that forum wasn't sure of the exact settings to use, and just copied an existing forum... Total guess, but seems as plausible an explanation as any.

The "new posts" page, on the other hand, doesn't use that table, and uses some temporary storage tied to your login session instead... the upside is that it shows posts from everywhere, but the downside is it gets reset every time your session resets - ie every time you log in, and every time you're inactive for long enough for your session to be purged (the "remember me" option automatically logs you back in, but it's a new session with a new cache).

I used to use Active Topics all the time until the event you described. Now I use New Posts, plus View Your Posts to dig a bit further back for anything I missed.

It seems I am unwilling to browse forum by forum.
