Today on the blog I start a new project: where do numbers come from?

By which I mean, mathematicians deal with lots of weird kinds of numbers. Real numbers, complex numbers, p-adic numbers, quaternions, surreal numbers, and more. And if you try to describe the more abstract types of “numbers” you sound completely incomprehensible.

But these numbers all come from somewhere. So I’m going to take you through a fictional history of numbers. Not the real history of the actual people who developed these concepts, but the way they could have developed them, cleaned up and organized. So in the end you can see how you, too, could have developed all these seemingly strange and abstract concepts.

This week in part 1, we cover the most sensible numbers. We start with the basic ability to count, and invent negative numbers, fractions, square roots, and more.

But that will still leave some important questions open—like, what is π? So we’ll have to come back for that in part 2.

Once again, I am tested by my circumstances. The local animal shelter was looking for someone to drive some dogs to their various appointments. That responsibility fell to me, a drivers-license-having individual with a community service requirement with an “exponent” symbol in it in Microsoft Excel, to truck them there. Nobody else wanted to do it, possibly because some of the dogs have what medical experts are calling “the terror shits.”

Naturally, I couldn’t do this in my own car. Not only is the Volare incapable of holding any passengers due to the structural rust issues, but I like to keep the car clean. That’s why there’s the big holes in the floor: any dropped candy wrappers, stray strands of hair, or spilled coffees will just run out when I lift the floor mat on the expressway. No: the animal shelter was very insistent that what I would receive is a 2005 Chevy Express van, white-on-white.

This van was, well, a van. For some reason, everyone I met was apologizing to me about “how old” it was, and how they had “no money” in the budget with which to upgrade it. I didn’t have the heart to tell them that it was several decades newer than anything I’d ever operated, and I was a little bit intimidated by driving something that could go forward and backward, without having to turn the engine off and push it a little bit first.

Still, after a few minutes on the road, I immediately saw what they meant. It didn’t have any soul, this new automobile, being enormously competent at virtually every task. It didn’t shake violently on the highway, all the doors stayed closed, and it could go around corners without the windshield falling out. Soon, I was going an integer multiple of the posted speed limit, still feeling it was too slow because the sensation of danger was no longer prickling its way up my spine. I was practically falling asleep, and when I arrived at the vet’s office an hour away nearly 45 minutes ahead of schedule, I decided something had to be done for the safety of my canine charges.

While the dogs were in the shop, getting their tires rotated, I decided to do a little bit of work on my own. I had been stuck behind a slow-moving BMW SUV on the off-ramp. It was now parked outside a realtor’s office, taunting me with its copious reserve of compressed air and torque. I decided that if they weren’t gonna use their turbocharger, then I should rightfully be entitled to it. After all, it’s for the public good: who would deny these dogs an efficient, comfortable ride? Using the BMW’s toolkit and a piece of parking lot rebar as a lever, I soon had the turbocharger worked off of the engine, dropped out the bottom, and swaged into the van’s induction system. To test it out, I jumped in and pinned the throttle a few times, hearing the delightful whoosh of at least a hundred more horsepower. Yeah. This would do nicely.

All I’m legally allowed to tell you about what happened next is two things. One, the van really was less boring after all this work. The little V8 sang with the joys of forced induction, and the tires smoked well through however many gears this magic future transmission had in it. Two, it was a good thing I was going to the dog groomer’s next, because none of these animals were in a presentable shape. It turns out dogs afflicted with the terror-shits don’t like to pull a deep thirteen-second quarter mile, which is definitely something they should have told me before they gave me the keys.

Not every day of volunteering is going to be perfect. Next time I go back, I think I’ll cut a hole in the floor instead. At least that will make the cleanup easier.

I’ve been thinking, with a lot of sadness, what I need to make fandom a large part of my life again (I want to, but at this point don’t think I can). One answer is LJ/DW kinkmemes. People don’t seem to do that much these days, and in any case then and now it can only exist for big fandoms. Centrally Marvel/DC universes, which I don’t enjoy.

I miss browsing prompts, posting prompts, writing a fill for a prompt knowing that at least one person was going to be an enthusiastic reader… I thrived in that environment. Writing alone feels really sterile. I want to be an ecosystem again.

This seems like a long shot. But:

If you know of an active kinkmeme (it’s okay if it’s small, as long as it’s alive), for a fandom you think I’ll like – please let me know. Here are some of my preferences:

  • Ideally, there are a lot of writers who are good. Some fandoms are unusually and confusingly full of good writers, like The Terror. Others are relatively sparse.
  • I like dark fic where people are sad and have sex that’s at least slightly unhealthy. I’m not an obligate dead dove writer, but a fandom where such fic would break norms is not for me.
  • I prefer to read and write about characters who are at least mildly intellectual, or can be interpreted as such.

actually you know what that’s exactly it i would rather someone add 5 parantheticals after every sentence than use tone indicators it’s 1. accomplishing SO much more in terms of clarity 2. extremely funny to look at depending on how they’re used

observe:

“is this real? /gen” — i thought /gen meant “general” for ages. i would not be able to understand this on first sight a few years ago and is thus ineffective

“is this real? (genuine question)” — i fully understand this without issue

“is this real? (genuine question) (can’t tell) (very realistic) (looks real) (scary) (photoshop?)” — is not only incredibly clear it’s also very funny to read all of these thoughts stapled together while also in their own parentheses. it’s also the most useful because now i can actually address all parts of what they are asking me with as much specificity as BOTH of us need

gendercensus:

The 2023 Gender Census is now open!

[ Link to survey ]

The 10th annual international gender census, collecting information about the language we use to refer to ourselves and each other, is now open until 9th May 2023.

It’s short and easy, about 5 minutes probably.

e489c77b6991f266ec4dee70d86209dc83e1a7af

After the survey is closed I’ll process the results and publish a spreadsheet of the data and a report summarising the main findings. Then anyone can use them for academic or business purposes, self-advocacy, tracking the popularity of language over time, and just feeling like we’re part of a huge and diverse community.

If you think you might have friends and followers who’d be interested, please do reblog this blog post, and share the survey URL by email or at AFK social groups or on other social networks. Every share is extremely helpful – it’s what helped us get 40,000 responses last year.

Survey URL: https://survey.gendercensus.com

The survey is open to anyone anywhere who speaks English and feels that the gender binary doesn’t fully describe their experience of themselves and their gender(s) or lack thereof.

Thank you so much!

As it is Passover again, it is time for the annual debate as to whether the frog plague, which thanks to a quirk in the Hebrew, is written as a plague of frog, singular, rather than the plural, plague of frogs, was in fact, as generally imagined, a plague of many frogs, or instead a singular giant Kaiju frog. This is an ancient and venerable argument that actually goes back to the Talmud because this is what the Jewish people are. If we can’t argue for fun about this sort of thing, what are we even doing.

In that spirit, I would like to submit a third possibility, which is that in fact it was one perfectly normal sized frog, who was absolutely acing Untitled Frog Game: Ancient Egypt Edition. One particularly obnoxious frog, who through sheer hard work, managed to plague all of Egypt.

Every time I go out to visit the midwest or mountain west I’m baffled as to how anyone lives in these gigantic flat plains or giant bowl valleys between mountains with no trees to speak of. It’s nature’s panopticon. You can go inside I guess but that roof can’t hide you from God like the woods can. It’s gorgeous of course but I’m going back to Mirkwood where I can think my wicked little thoughts in peace, thank you very much.

i feel the same except the complete opposite. the mountains are nice to visit but how does anyone live there? you don’t know what’s hiding in there. peace is endless flat plains, nothing but you and the angel you’re struggling with.

fascinating! enjoy the type of horror that feels like home to you and I will do the same xoxo
