I first heard about this study in von Kármán Lecture at JPL from February of this year. (http://www.jpl.nasa.gov/events/lectures_archive.php?year=2015&month=2)

Last fall, we let you know that Caltech and The Feynman Lectures Website joined forces to create an online edition of The Feynman Lectures on Physics. They started with Volume 1. And now they've followed up with Volume 2 and Volume 3, making the collection complete.

This was part of mine.
 
Watch the thrilling first run of the giant Hot Wheels loop installation at the Maker Faire in Detroit this weekend.
