   I just tried with Firefox 54.0.1 on macOS, and it seems to work. What version are you using?

   Yeah, I think you're thinking of a Bring radical: https://en.wikipedia.org/wiki/Bring_radical Edit: Oh, but that only lets you solve some quintics. https://news.ycombinator.com/item?id=14686886 de

   I'm a bit out of my depth here, but I think you can generalize it to differential fields, where you want to figure out e.g. which functions have a closed-form integral. A reference (the only reference?) would be Topological Galois theo

   Thanks, I see why it's confusing. I'll fix it!

   Because we start off with the candidate solution matching the real roots, and we continuously move the roots to swap them. At every point of the movement, the candidate solution match the real roots (including order) by assumption, and so

   Yeah. I think I punted on that because, although it's easy for degrees <= 4 (since those have general formulas!), I'd have to implement some root-finding method for degrees >= 5, and somehow preserve the orderings of the roo

   Yes, that's correct. That's the big disadvantage to the topological method I talk about (developed by Vladimir Arnold); it can only prove stuff about the general nth-degree formulas, whereas Galois theory can prove stuff about spe

    Here is a damning Twitter thread comparing the article to Lola's published obituary: https://twitter.com/caulkthewagon/status/864656017480708102 It makes the author and his family a lot less sympathetic.

    I found this to be a way better resource than the "Music theory for nerds" article floating around a while ago.

    Thanks for the recommendations! Did you mean something specific when you referred to "Bostock's notes", or did you just mean his various blog posts and papers?

    Interesting! How'd you know that about the developer's situation? Digging around kapeli.com, it doesn't talk much about it.
