This weekend I enjoyed a nine-hole round of disc golf—a great way to enliven an outdoor walk via some friendly competition and the satisfying clink of chains when making a shot.

The trick is to control the pitch of the aerodynamic platters. They must be thrown at an angle that better players than me, such as my oldest son Ben, refer to as ‘hyzers’ or ‘anhyzers’. I am not quite sure which is which. All I can think of when he tries to explain the difference is that I really need a six pack of Anheuser-Busch beer when my anhyzer throw goes off into a bush, which happens far too often.

Check out this greatest shot (an anhyzer?) in disc golf history by World Champion James Conrad earlier this month.

Getting back to beer, this recent report by Ars Technica provides a ‘heads-up’ on why coasters fly so poorly—flipping on average only a half second into their flight. See all the details in Beer Mats make bad Frisbees published by three German physicists last month. Evidently “the crucial effect responsible for the flipping is found to be the lift attacking not in the center of mass but slightly offset to the forward edge”, which “induces a torque leading to a precession towards backspin orientation.”  Now you know!  It’s not that you are drinking too much due to being quarantined too long during the pandemic.  Whew!
