A couple of weeks ago, I got a cool picture of snow hanging off SteelyKid’s playset, and posted a call for people to suggest physics-y ideas about that. I only got one response, probably because nobody really read the Internet over the holidays.
Anyway, the next time I’m likely to have the free time to write anything substantive is next Tuesday morning, so let me renew that call now, while people are trapped indoors by the POLAR VORTEX! with nothing to do but think about the physics of cold things. So, if you have physics-related ideas about the photo above (there’s a view from a different angle at the link), send them to me by next Monday, and I’ll write something up on Tuesday.
