Trapezoids, and blogs
Atrios remarked on the (slow, inprogress) death of the open internet, as in blogs etc. And Jonathan’s offhand remark about his blog’s heyday is another anecdatum pointing in the same direction. Anyhow, that’s not what this post is about; it’s … Continue reading
Medals per capita
So I made a joke to a friend about how, after Slovenia got their first medal, they were doing really well on a medals per capita basis. And then, being me, I took this joke too far and actually started … Continue reading

American woman math PhDs of the 1940s
Apparently I’ve had this blog for a really long time: just over nine years ago, I wrote about Margaret A. M. Murray’s book “Women Becoming Mathematicians”. This post is just to note that the latest AMS Notices contains an article … Continue reading
Jargon
This tickled my fancy: For all the other parameters, has no real structure. [R. Corran, E.K. Lee, S.J. Lee, Braid groups of imprimitive complex reflection groups, J. Algebra, 2015] (No, it’s not floppy — it’s a complex reflection group. Here … Continue reading

Over at JD2718, Jonathan asks the following question: [A conference] presenter posed a problem that required finding three numbers that multiplied to make 72. The list included 1, 8, 9 and 2, 2, 18 and 3, 4, 6 and several … Continue reading
Open problems in algebraic combinatorics

“Dialogues on mathematics” by Alfred Renyi
For various reasons I have recently been reading a bunch of books broadly addressing the theme “what is mathematics?” (Linderholm was accidentally a leadin, and clearly belongs in the category.) This one is a short (under 100 pages) and snappy read, … Continue reading
“Mathematics Made Difficult” by Carl E. Linderholm
I have seen attributed to Halmos (Linderholm’s advisor) the description of this book as an injoke to the mathematical community, and that’s about right: I don’t think it would be possible to explain why it’s funny to someone who doesn’t … Continue reading
