Flying fish and diving birds often navigate the interface between water and air in their flight, but few studies have actually looked at the effects of this transition on lift. Keep reading

Hovering Hawk
Birds have a level of control in flight that would make any engineer jealous. This 2021 Audubon Photography Award winning video by Bill Bryant shows off the skills of a Keep reading
Tokyo 2020: Baseball Aerodynamics
For a long time, people thought baseball aerodynamics were simply a competition between gravity and the Magnus effect caused when a ball is spinning. But the seams of a baseball Keep reading
Tokyo 2020: Sailing Faster Than The Wind
It’s a bit mindboggling, but by exploiting physics and geometry, a sailboat can reach speeds faster than the wind propelling it. Steve Mould demonstrates how in this video using some Keep reading
Tokyo 2020: Visualizing the Magnus Effect in Golf
Golf returned to the Olympics in 2016 in Rio and is back for the Tokyo edition. Golf balls — with their turbulence-promoting dimples — are a perennial favorite for aerodynamics Keep reading
Tokyo 2020: Volleyball Aerodynamics
Like footballs and baseballs, the trajectory of a volleyball is strongly influenced by aerodynamics. When spinning, the ball experiences a difference in pressure on either side, which causes it to swerve, per the Magnus Keep reading
When Squids Fly
Some species of squid fly at speeds comparable to a motorboat for distances of 50 meters. The cephalopods get into the air the same way they swim underwater: by expelling Keep reading
Challenges of Commercial Supersonic Flight
Years ago as I sat on a plane taxiing at Heathrow, I caught a glimpse of a Concorde out on the tarmac. My classmates couldn’t understand why I was so Keep reading
Wind Turbine Physics
Over the years, wind turbines have gotten tall with long, thin blades. This MinutePhysics video delves into the reasons for those changes. They’re all aimed at generating more wind power Keep reading
Streamlining Circa 1936
This 1936 promotional film by Chevrolet explains the concept of streamlining objects to reduce their drag. And it actually does a pretty nice job of it, including some wind tunnel Keep reading
