At first glance, this image looks much like the impact of any drop on a pool of the same liquid, but that’s not what you’re seeing. This is the impact Keep reading

Jumping Droplets
Condensation, which removes heat by changing a vapor into a liquid, is a common feature in industrial heat transfer. When droplets form on surfaces, they typically have to grow to Keep reading
Seeing the Wake
Hot exhaust gases churn in the wake of this climbing B-1B Lancer. The high temperature of the exhaust changes the density and, thus, the refractive index of the gases relative Keep reading

Pilot-Wave Hydrodynamics: Walking Drops
This post is a collaborative series with FYP on pilot-wave hydrodynamics. Previous entries: 1) Introduction; 2) Chladni patterns; 3) Faraday instability If you place a small droplet atop a vibrating Keep reading
Pilot-Wave Hydrodynamics: Faraday Instability
This post is part of a collaborative series with FYP on pilot-wave hydrodynamics. Previous entries: 1) Introduction; 2) Chladni patterns In 1831, in an appendix to a paper on Chladni Keep reading
Pilot-Wave Hydrodynamics: Introduction
For the next week on FYFD, I’ll be doing something a little different. I’ve teamed up with FYP to produce a joint series of posts on pilot-wave hydrodynamics, a recent Keep reading
Hair-Washing in Microgravity
I imagine that the most common questions astronauts get come in the form, “How do you do X in space?” In this video, astronaut Karen Nyberg demonstrates how she washes her Keep reading
