Cookin' up Tweets

 IF you’re on Twitter and you’re interested in math-related material, then you likely already know of John D. Cook and his terse blog posts, but you might not be aware of ALL his Twitter accounts (I guess there are worse addictions one could have! ;) 

Check them out here:

https://www.johndcook.com/blog/twitter_page/

He’s at 18 accounts thus far; can y’all think of just a couple more to get him to a nice round 20? or, even one more would make 19, nicely prime and Lance Alworth’s old jersey number with the San Diego Chargers! ;))

Another splendid post from Brian Hayes (this time on prime numbers & “tweens”):

Probably room for a lot more work on this... primes are endlessly fascinating.

Like A Horse and Carriage (math & music)

 Personally, I've always believed in a cognitive linkage between math and music, in part because of the number of individuals I've encountered who were either math majors and music minors, or vice-versa, music majors with math minors... and there are other reasons as well. Apparently, though, some folks doubt the connection, which this study now seems to back up:
