December 6, 2013, 12:00 amFrom Wikipedia’s entry on Super Balls.
Wham-O Executive Vice-president Richard P. Kerr said, “Each Super Ball bounce is 92% as high as the last.

Harvey Mudd is known as one of the most elite science, engineering and mathematics colleges in the world. But historically, its computer science department hasn’t exactly been known as a paragon of gender diversity — in 2006, only 10 percent of Harvey Mud...
Fun Little Calculus Gif
September 26, 2013, 12:00 amYet another cool image from the Visualizing Math Blog.
I was wondering if I could recreate this graph in Desmos. Here’s what I was able to make.
It was difficult to find a way to keep the tangent line the same length, although I bet a parametric form of the line would work better tha...

Awesome cat photo from misadventures in HR.
If a cat could fill out a bubble sheet, and left parts II, III, and IV blank (assumption: cats can’t write in english) then the following is based on the 2013 June Regents scoring scale:
1 in 36,000 cats would pass the Integrated Algebra Regents...

TOM: Yes.
RAY: A squared, plus B squared, equals C squared. And there are numbers like three, four and five; five, 12, 13 which satisfy that little equation. And man...
