@freemo Bro, they are warm. Try it. It's like wearing an entire extra layer.

@yojimbo @kashi Thanks, I hate it.

@freemo Reading math as basically all I do at this point in my PhD and I still find myself going at a rate of about an hour a page for some work, sometimes due to its genuine density, and sometimes due to the quality of the exposition. It's exhausting. Math, by its very nature, is built out of definitions and theorems, including these necessary pieces in your work is hard enough, communicating the intuition and ideas on top of that is something very few people can do effectively.

@design_RG @freemo I should comment that this is not book that is meant to be read by anyone other than mathematicians. Its an AMS monograph on a modern theory that started being developed, I think, in the 80's, namely information geometry. It's also, as far as I know, the first text on the topic. This line was just laughably convoluted for what he was trying to say.

Math books be like this. Stared at this a long time before I realized it was just basically saying that the product of a matrix with its inverse is the identity. Lol why

@matrix cursed

@mngrif This is incredibly cosy.

@xahlee@mstdn.io What have you got against ginger?

@xahlee@mstdn.io I love haskell, it's one of the most elegant and expressive languages out there. The problem is that its utterly undisciplined development makes it useless for all practical purposes as the developers prioritize adding more advanced features over performance or reliability. Additionally lazy first causes nightmarish problems with space leaks and unpredictable performance.

@binsrc Newtonian physics can actually be taught at a low level as it only requires algebra if taught with a few kinematic equations and the full view comes with only basic calculus. Attempts to teach "Eistienian physics" will simply be teaching a pop science version of the ideas fairly removed from the actual theories. I mean the article talks about straight lines intersecting in curved space but what the heck is a line in curved space! You need the math.

@xahlee@mstdn.io This is a strange object. The only term I could find for it is an n-inner product or 2-inner product in this case as in https://www.researchgate.net/publication/268174205_On_n-inner_product_n-norms_and_the_Cauchy-Schwarz_inequality. Where did this come up?

@design_RG Thank you for the introduction.

First post!
Decided to try social media again, so here's an illustration of the perfection of six. A perfect number is the sum of its positive dividers i.e. 6 = 1+2+3.
