It was bitterly cold over the weekend here in the Northeast, with daytime high temepratures in the single digits Fahrenheit. This has little to recommend it in terms of, you know, leaving the house, but it did provide an opportunity to try some SCIENCE!
Unfortunately, I left the notepad with the data (such as it is) on it at home when I came to Starbucks to write, so I can't do the detailed write-up. I'll use it for the photo of the day, though, from which you can probably guess what I was trying to do:
Starting condition for a science experiment.
Detailed explanation of methods and results later today, or maybe tomorrow.

Consider the air around you, which is hopefully at something like "room temperature"-- 290-300 K (60-80 F). That temeprature is a measure of the kinetic energy of the moving atoms and molecules making up the gas.
Anthony Watt's blog seems to be a rather high profile climate sceptic site that usually seems to at least try to have substantive content, but I can't see
Physics Web has a story about new discoveries in excitonic systems with the eye-catching headline BEC's confound at higher temepratures.
