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: High-Dive Physics
In Olympic high-diving, athletes leap from a maximum of 10 meters above the water. Although the force of their water impact is substantial, it’s small enough that they can enter 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: Optimizing Oar Length
The sleek hulls of racing boats are designed to minimize drag, but there’s optimization to the oars as well. Mathematical models – and the history of rowing – indicate that Keep reading
Tokyo 2020: Surf Physics
Surfing is making its Olympic debut this year with a shortboard competition held at Shidashita Beach, with the event’s timing determined by weather and wave quality. The fluid dynamics involved Keep reading
Tokyo 2020: Future Swim Tech
Recent controversies over swimsuit technologies haven’t damped the creativity of Speedo’s marketing staff. They recently unveiled Fastskin 4.0, a futuristic concept designed for the swimmers of 2040*. They’ve envisioned a Keep reading
Tokyo 2020: Sailing Physics
At first glance, sailboats don’t look much like an airplane, but physics-wise, they’re closely related. Both the sail and hull of a sailboat act like wings turned on their side. 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
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
