Two for Thursday, via Ben Orlin, Keith Devlin

1)  All aboard the number line... I shouldn't even bother linking to this posting of Ben Orlin's from yesterday... because ALL OF YOU SHOULD BE FOLLOWING HIM REGULARLY ON YOUR OWN by now! (if you're not, get with the program... so I can quit shouting).
Great stuff from Ben, taking us on a journey to-and-fro the number line:

2)  When someone on Twitter asked Keith Devlin about "KIC 5520878 and the golden ratio," he responded, "That one is intriguing. Most GR claims are nonsense. But I'm keeping an open mind on this one, b/c of cont fraction rep of GR."

So I had to look that one up to get the backstory. And here it is from Natalie Wolchover:

Ben and Natalie Deliver

1)  Of math tests, fair and otherwise...
Another post from Ben Orlin that had me alternating between chuckling and thinking (...and trying to figure out how he gets SO MUCH expression into stick figures!):

And YO, Ben, get your tail back over HERE... we can't be sharing your level of talent with Scotland, when you're needed badly in the U.S.! ;-)

2)  Now if you're wanting a little more serious, mind-stretching math, DO NOT MISS Natalie Wolchover's latest exquisite piece on "graph coloring" for Quanta Magazine:
