Bursting at the seams this week:

**1)**John Pavlus tries to explain, very briefly, why P vs. NP is such a big deal:

**2)**Another recreational math book to look forward to (but unfortunately not due out 'til January 2016, not in time for the holiday season):

**3)**Keith Devlin has recommended the following site for some online math:

(I don't have any experience with it except that Dr. Devlin recommends it)

**4)**Speaking of Keith, another Devlin podcast interview (38-min.), this time with Hemant Mehta:

**14)**A link from

*earlier in week that I think worth reiterating -- Lior Pachter's post on possible problems for Common Core:*

**Math-Frolic**https://liorpachter.wordpress.com/2015/09/20/unsolved-problems-with-the-common-core/

Potpourri

**(extra NON-mathematical links of interest):**

*BONUS!*1) Don't know how many of you have already seen this video that went semi-viral a couple weeks back, of an (extinct) pterosaur flying over Idaho! -- I just saw it this week and thought it was fun (despite its flaws)... most are presuming it's CGI (or some think it's a kite), but I'd find it more interesting if it's a drone dressed up in pterosaur garb:

(if anyone has learned an official, definite explanation let us know; I've seen plenty of speculation)

2) More monkeying with the copyright law:
