good-bye Olympics

Some food for thought as the Olympics come to an end.

I enjoyed watching Usain Bolt break a few world records. If you’re a geek like me, you noticed that he was actually faster when running 200m than when running 100m (looking at average speed), due to the time to accelerate. Freakonomics has posts on the average speed as well as extreme outliers in the 200m distribution.

Did the US win the medal count? Not is you only count gold medals or adjust for population and GDP (Read another ranking for GDP and population).
