Time to slip in another ASMR video. "Angelo" has probably become my favorite within the shoeshine genre, so yet another from him:

A lot of folks interested in mathematics are also interested in chess, so without further adieu, a post with some interesting chess thoughts:

There have been, and will be, many tributes to Steven Weinberg this week; I highly recommend this very personal one from Scott Aaronson:

Mathematician Michael Harris, author of "**Mathematics Without Apologies**," announces a new newsletter to concern itself with AI and the mechanization of mathematics:

This weekend you can either breeze your way through Tolstoy's "**War and Peace**" or slowly work your way through the latest from Brian Hayes ;))

Starting with this equality (from a Cliff Pickover tweet):

**Futility Closet** points out this further elaboration:

Haven't had a chance to view it myself yet, but Sean Carroll's latest guest on his **Mindscape** podcast is Stephen Wolfram, so ought be interesting (over to 2.5 hrs.):

A few Alex Bellos puzzles (actually from philosopher Joel David Hamkins) to jumpstart your week:

ICYMI, here was July's very varied ** Carnival of Math** (the 195th such compendium), full of interesting reads for your weekend:

Joselle (...and David Deutsch), at "**Mathematics Rising**," waxes eloquently about knowledge, mathematics, and the universe... nice read/contemplation for a Sunday morning:

Have always found the linkage between math and music interesting, especially since encountering so many individuals over time who were music majors with math minors, or, vice-versa. Anyway, noticed newish book during trip to bookstore this morning that looked interesting (but haven't read, so just supposing), "**Music, Math, and Mind: the physics and neuroscience of music**" by David Sulzer:

A little end-of-week humor... I don't see a lot of new math humor these days that really makes me chuckle any more, but this bumper sticker recently seen on **Twitter **(H/T Simon Pampena) did (...though perhaps it's quite old and I've just missed it or forgotten it):

I've talked of self-describing sentences or "autograms" here before (I love 'em, and their GÃ¶delian flavor!), and recently **Futility Closet** posted this fine example (with Lee Sallows involved as he often is):
