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
Mimicking Insect Flight
There’s an oft-repeated tale that science cannot explain how a bumblebee flies. And while that may have been true 80 years ago, when engineers assumed they could apply their knowledge Keep reading
Crocodilian-Inspired Aerodynamics
Inspired by crocodilians, young scientist Angela Rofail designed attachments to reduce wind loads on high-rise buildings. When crocodilians swim, the ridges on their back help hide their motion from observation Keep reading
Aerodynamic Flight Testing
Flight testing models has a long history in aerodynamics. Above you see a Curtiss JN-4 biplane in flight with a model wing suspended below the fuselage. This test was conducted Keep reading
COVID-19 and Outdoor Exercise
By now you’ve probably come across some blog posts and news articles about a new pre-print study looking at the aerodynamics of running and the potential exposure to exhaled droplets. Keep reading
Why Do Backwards Wings Exist?
Over the years, there have been many odd airplane designs, but one you probably haven’t seen much is the forward-swept wing. While most early aircraft featured straight wings, rear-swept wings are Keep reading
