While I'm at it, I'd like to share two things today.
First, the world's tiniest snowman measures 0.01 mm and even has a nose!
This isn't snow though. He's made of two tiny tin beads bounds by some platinum. The face features have been designed with a focus ions beam. The link is here.
The second thing I'd like to share is a video showing droplets falling, but imaged at a rate of 2000 images/second...
I'm must confess that I don't remember much from my surface physics class, except maybe that interfaces require more energy than bulk to be created and that this is why nature tends to reduce the surfaces extent by creating spheres. I would have been more interested by this class if it had started by such a video.
