Despite a few glitchy matters and some selections sent in that weren’t usable for various reasons, the “All-star linkfest” I sought is finally ready for prime-time. In retrospect, it seems like a near-impossible task, to pick out just 1 or 2 favorite math postings from a Web inundated with great mathematics, as the variety here will indicate:

Originally I kicked the project off citing a 2015 Lior Pachter piece on K-12 math education, with many great suggestions for math problems young people can work on:

…another

*long*education piece I always think of in conjunction with Pachter’s piece (even though they are quite different) is this 2012 one from Fields Medalist Timothy Gowers on teaching math to non-mathematicians (with a couple hundred comments as well):
So much for me though, here are YOUR picks (in no special order):

Steven Strogatz surprised me a bit when he wrote that his first thought was this link to a mathematical fiction site (which is definitely useful for folks who like to link their love of fiction with their love of math — 100s of selections):

…but then as a more mathy choice (that he noted “

*everyone interested in math should read*”) Dr. Strogatz went with this classic from his former fellow Cornellian(?) William Thurston, “*On Proof and Progress In Mathematics*”:
No surprise that someone would pick Steven Strogatz himself for great postings, and Patrick Honner cited Dr. Strogatz's fantastic

https://opinionator.blogs.nytimes.com/2010/01/31/from-fish-to-infinity/**NY Time**s' series that started here (and led to an eventual book based on the series):
I would’ve been shocked if no one had chosen something from Grant Sanderson’s incredible

*3Blue1Brown***YouTube**site, and I wasn’t disappointed. Sol Lederman (who it was great to hear from), formerly proprietor of the immensely popular “*Wild About Math*” blog, picked out Grant’s video on Euler’s Formula & group theory:
And Benjamin Leis also opted for the fabulous

**3Blue1Brown,**singling out this one on Pythagorean triples:
Mathematician/computer-scientist/author Rudy Rucker sent in this highly graphic selection on the Mandelbulb, a 3-D version of the better known Mandelbrot Set:

Colin Beveridge went with a

**StackExchange**discussion of a Gaussian proof:
[…this made me think that another possible interesting “linkfest” might be to have readers send in their all-time favorite math questions/discussions/debates from forums like

p.s.... any mention of Gauss can't help but also make me think of this favorite old humor site on "Gauss Facts" (too funny):

http://www.gaussfacts.com

**StackExchange, MathOverflow, Quora, Reddit**, etc. I don’t read any of these sites regularly myself, but know there have been some great postings on occasion there.]p.s.... any mention of Gauss can't help but also make me think of this favorite old humor site on "Gauss Facts" (too funny):

Of course none of us will forget the wonderful life-work Alexander Bogomolny left us with his

**Cut-the-knot**site and Jim Wilder pointed to two problem-selections from there:
Jim Propp couldn’t contain himself and sent in the most links, six (including one from Evelyn Lamb and one from Ben Orlin), and because I like Jim so much I

*almost*let him get away with it… am passing along 5 of his diverse picks here (the first four have a lot to say*mathematics, while the last one involves doing mathematics):***about**

https://gravityandlevity.wordpress.com/2018/07/06/lagrange_multipliers/

From Tim Chartier came this numerical math trick (requiring flash):

Meanwhile, leave it to Ben Orlin to send in cartoon work (not his own), on math myths, for readers to appreciate:

Statistician Adam Kucharski passed along this interesting one on random numbers and casinos:

Also related to randomness, Don McDonald sent in this recent Noson Yanofsky piece:

An entry I particularly liked came from great math popularizer Richard Elwes with this longish piece on math foundations:

One individual wished to remain anonymous (not sure why) and sent in this somewhat classic Terry Tao piece (that’s readable by a general audience) on rigor in mathematics:

Colm Mulcahy went with Tyler Vigen’s spoofy, always-good-for-a-chuckle ‘Spurious Correlations’ website, illustrating, believe-it-or-not, 'correlation is not causation' ;)

Another graphic site (Tumbler) came from Jo Morgan:

Meanwhile, James Tanton and Edmund Harriss sent along education-related websites:

James: https://mathigon.org

Edmund: https://talkingmathwithkids.com/

That's it! It's been fun for me to collect these and offer up some sense of the great variety of items that mathematicians enjoy/recommend within their own field.

[…let me know of any non-working links or other problems, and you can still add your own "faves" in the comments]
