Hovering
Nectar-drinking species of hummingbirds and bats are both excellent at hovering – one of the toughest aerodynamic feats – but they each have their own ways of doing it. Hummingbirds Keep reading
An Introduction to Turbulence
With some help from Physics Girl and her friends, Grant Sanderson at 3Blue1Brown has a nice video introduction to turbulence, complete with neat homemade laser-sheet illuminations of turbulent flows. Grant Keep reading
Making a Square Vortex
As someone who has played with her share of vortex cannons, I can assure you that messing around with smoke generators and vortex rings is a lot of fun. And in Keep reading
Carbonation in Microgravity
Bubbly beverages are popular among humans, but there’s surprising complexity underlying their seemingly simply carbonation, as explored in a new Physics Today article. Most drinks get their bubbles from carbon dioxide, Keep reading
The Tacoma Narrows Bridge
One of the most dramatic and famous engineering failures of the twentieth century is also one of the most complicated: the collapse of the Tacoma Narrows Bridge. This early suspension Keep reading
Nacreous Clouds
During winter, the polar skies can ignite with mother-of-pearl-like iridescence. Polar stratospheric clouds – also known as nacreous clouds – are a rare, beautiful, and destructive type of cloud found Keep reading
“Float”
In “Float” artist Susi Sie uses water and oil to create a whimsical landscape of bubbles and droplets. Coalescence is a major player in the action, though Sie uses some clever Keep reading
