2020 was certainly a strange year, and I confess that I mostly want to congratulate all of us for making it through and then look forward to a better, happier, healthier 2021. But for tradition and posterity’s sake, here were your top FYFD posts of 2020:
- Juvenile catfish collectively convect for protection
- Gliding birds get extra lift from their tails
- How well do masks work?
- Droplets dig into hot powder
- Updating undergraduate heat transfer
- Branching light in soap bubbles
- Boiling water using ice water
- Concentric patterns on freezing and thawing ice
- Bouncing off superhydrophobic defects
- To beat surface tension, tadpoles blow bubbles
There’s a good mix of topics here! A little bit of biophysics, some research, some phenomena, and some good, old-fashioned fluid dynamics.
