Steven Strogatz has written a book based on his series of columns for the New York Times, The Elements of Math. The book’s called The Joy of $x$, and Steven’s recorded a trailer for it. I bet he hopes the trailer will convince you to buy the book.
That trailer’s got it all! A jazz soundtrack, a cool dude, a surprise moustache; everything. It makes a compelling case1.
There’s also a video of the outtakes from the trailer:
For the past couple of weeks, I’ve been obsessively playing the game Twenty on my phone. Then I decided to make my own game in a similar vein. The fact that my wife has consistently been ahead of my high scores has nothing to do with it.
