allofthemath: This, ladies and gentlemen and genderqueer folks, is Pascal’s tetrahedron, a three dimensional analogue of Pascal’s triangle, and it’s pretty freaking great. I’ve never heard of this before!

tigburr: coolmathstuff: allofthemath: appliedmathemagics: themathkid: Can’t. Stop. Watching. this is hypnotic… Conic sections are all connected! A hyperbola is an anti circle, in this case. Remember, the equation for a circle involves adding x squared and y squared, while the equation for a hyperbola involves subtracting one from the other. The other consequence of this is that is that if you extend the graph of either one to include imaginary and complex x or y values, a hyperbola […]

5:00 PM | Sociopaths, PhDs, Mathematicians, and more
Jordan Ellenberg offers an observation on why mathematicians (generally) are NOT sociopaths (unlike, perhaps, investment bankers ;-):http://quomodocumque.wordpress.com/2014/04/22/why-arent-math-professors-sociopaths/Meanwhile, possibly on the opposite end of the spectrum is Jason Padgett's story, which I've reported here previously -- an individual with "acquired" savant syndrome, that appeared later in life following significant brain trauma, recounted in Padgett's new volume "Struck by […]

jtotheizzoe: Happy Earth Day! Here is a new time-lapse of images from the International Space Station, titled The World Outside My Window. You may not be looking at it from this perspective, but you’ve got a world outside your window, too. Take care of it. Turn up your speakers, go full screen, and lean back. Heck … this one even goes to 4K. Enjoy. (video by David Peterson)

(Click on the cartoon to see the full image.) (C)Copyright 2014, C. Burke.That's the yolk. I was working on the monologue for a while before I realized if anyone were willing to read more that two paragraphs of my prose, I could sell a few stories. I couldn't tag this one "PI", because it's not "pi". And if I make a new "P.I." tag, I'd have to go back and tag most of the "Pi" comics.

3:00 AM | Monday Puzzle: How many odd-even sequences are there?
From the numbers 1, 2, … n, start by writing an odd number, and keep writing larger numbers–alternating between even and odd–until you stop at n. Call this an odd-even sequence of n. For example, if n = 3, then the only odd-even sequences are 123 and 3. If n = 8, then the sequences […]

Simplistic, but quite to the point… “I’ve never been female, but I’ve been black all my life and so let me perhaps offer some insight from that perspective. I got to see how the world around me reacted to my expressions of these ambitions. All I can say that is the fact that I wanted […]

It's okay to put hard-boiled eggs in one basket because you want them all to break so you have an excuse to throw them all out! Seriously, I know some people who eat them, but I know few who enjoy them.
