(side note: beware of the f-bombs!) It's strong, it's progressive, I love it. & I thought it was an appropriate title since cycling is a way to escape & duck out from life once in awhile ;-) Today's workout is a little more than 30 minutes, but don't let that fool you. It can still be hardcore & as intense as you want to make it. BUT you can also use this one as a good starter workout to pace yourself. Grab your water bottle & towel...Here's the profile:1) Warm Up2) Rolling Hills3) 30 sec Intervals4) Climb with Power5) Jog & Jumps6) Sprints7) Cool-down8) Stretch

Gyroscopic Precession - YouTube
NOTE: This video will appear in a playlist on Smarter Every Day hence the references to Veritasium. Destin does lots of cool science stuff - check out his channel if you haven't already http://www.youtube.com/destinws2 We have been collaborating on rotational motion, which is timely for some of the videos I've been doing lately. In this video I talk about gyroscopic precession - the "wobbling" of a spinning top around its axis. This is caused by the torque due to the object's weight. The big idea is that the torque vector increases angular momentum in the direction of torque. So if there is no angular momentum initially, it will cause the system to swing in such a direction that it is rotating with new angular momentum in the direction of the torque. However, if there was angular momentum to begin with, the torque will change the direction of that angular momentum by causing precession.
