Holidays fun.

Via Richard Wiseman.

Poetic science.

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.

F = ma

This video is already somewhat old, but if you missed it then, here it is!



While looking for it, I found out that the MIT has a large database of educational videos online, including a full class on classical mechanics.

The fantasy of any undergrad physics student is to attend a lecture given by Richard Feyman, known as an excellent pedagogue. With internet, it's almost possible!
