about this:

I’m interested in a lot of things, but somewhat more nervous about talking about them online and under my real name, so mostly I’ve been writing about math.

about me:

I live in Seattle, for now, and am working at Dropbox. Of course nothing I say here is in any way speaking for my employer.

I am not a mathematician or physicist and am definitely not credible at all, please don’t look at me like that. I try to stick with “explaining things better than Wikipedia does” because it’s harder to be wildly wrong that way.

If for some reason you want to contact me, go for it. I’m at alex.kritchevsky@gmail.com. I’d be delighted to hear from you.
