Analysis of NBA Finances

This is a comprehensive and insightful look into the NBA’s claims of financial distress from Nate Silver:

As the NBA prepares to battle the player’s union over revenue, the league has made several public claims about how they have been losing money for years.

Silver takes a deep look into those claims.  He crunches the numbers and compares player revenue as a share of league revenue across the four major sports leagues; he looks at salary growth relative to league growth; and he also discusses some of the dubious accounting tricks teams and leagues use to make profits disappear!

As usual from Nate Silver, this is a very interesting and readable application of mathematics and statistics.  His conclusion is summed up best by a recent message from @fivethirtyeight on Twitter:  “If David Stern really thinks the NBA lost $370 million last season, shouldn’t he have fired himself?”

Automatic Origami

This video from New Scientist demonstrates some amazing self-unfolding origami.

In the video, a carefully folded-up piece of paper is placed on the surface of the water.  As the creases in the paper absorb the water, they start to expand, causing the shape to unfold.

As each subsequent layer unfolds and hits the water, the process repeats, until the shape is completely unfurled.  It’s interesting to consider the potential applications of this process.  An origami life boat, perhaps?

Yet another amazing way to have fun with folding!
