The Unapologetic Mathematician is a personal blog at unapologetic.wordpress.com about math. Since 2010, 4 different Hacker News readers have linked it 4 times. The last post was in 2012, but the archive is still widely read.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link The Unapologetic Mathematician for mathematics posts on category theory, matrices as linear maps, and root systems with Dynkin diagrams and Coxeter groups.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Mathematics for the interested outsider

For those who want to know more, this topic links nicely into A-D-E theory, Dynkin diagrams, and Coxeter groups. https://www.youtube.com/playlist?list=PL-XzhVrXIVeSVcV9iRJ4S... https://www.youtube.com/playlist?list=PL-XzhVrXIVeQ298S6uCyo... http://math.ucr.edu/home/baez/week230.html https://unapologetic.wordpress.com/category/geometry/root-sy... http://www.math.harvard.edu/~lurie/papers/thesis.pdf Beautiful world th…

HN discussionSo yes, this is equivalent to FinVect of the field of which entries in the matrices consist. The difference is that here you construct the category from a simpler premise. To construct FinVect you need to include all set objects with structure satisfying some axioms. The category of matrices is simply positive integers with as morphisms n x m matrices between the two integers. Composition is matrix multiplication. H…
