Frog Tongues and Parrot Laser Safety Goggles
What do frog tongues, whisky, tattoos, and parrot laser safety goggles have in common? They’re all a part of the latest FYFD video! Check out my behind-the-scenes look at the Keep reading
Behind the Science
FYFD features lots of science, but this new video gives you a chance to see the scientists, too! It’s a behind-the-scenes look at the American Physical Society Division of Fluid Keep reading
Vertical-Axis Wind Turbines
Vertical-axis wind turbines (VAWT) are an alternative to traditional wind turbine designs. Unlike their more common cousins, VAWTs rotate about a vertical axis and are omni-directional, meaning that they do Keep reading
Cavitation
[original media no longer available] Cavitation–the formation and collapse of vapor-filled cavities within a liquid–occurs in a variety of natural and manmade applications. It can shatter bottles, wreak havoc with Keep reading
Crown Sealing
Objects falling into a liquid pool create a beautiful splash, and, in this beautiful, award-winning video, the Splash Lab explores a peculiar instability that occurs just as the splash closes. Keep reading
Sound Interactions
Sound waves often interact with many objects before we hear them. Understanding and controlling those interactions is a major part of acoustic engineering. The animations above show shock waves–sound–from a Keep reading
Wave Clouds
Coming home from APS DFD, I looked out the window as we flew east over the last of the Rockies and caught these wave clouds. Air flowing west to east Keep reading
Piazza del Popolo
The lions of the fountain in Rome’s Piazza del Popolo eject a turbulent sheet of water. Random fluctuations in the water sheet cause holes to form. Driven by surface tension, Keep reading
APS DFD 2014
It’s that time of year again! Sunday marks the start of the 67th Annual Meeting of the American Physical Society Division of Fluid Dynamics. I’ll be in San Francisco for Keep reading
