It’s evaporative cooling, baby!

I haven’t posted here in a long time. There’s a few reasons for this. One, I’m really hosed in lab. I’m upgrading a cryostat and have been battling mechanical compatibility and cryogenic issues for over 2 months now. A more awesome reason is because I recently traveled to the east coast. I was in Boston for Steer Roast and Dave’s thesis defense (he passed!), and then went up to VT for a few days to see my family. My brother and I got my dad a homebrewing kit for his birthday, and now my brother and dad are brewing up lots of beer. Then I went to NYC, (which I hated) but despite my hatred for the city I had fun because I got to see many old friends from the quanta lab who I haven’t seen in a long time. Then it was back to Boston for the 7th Annual Blow Shit Up Day (+barbecue). By the time I left to return to Berkeley, I was thoroughly exhausted.

I spent the last week dying from a terrible cold (likely brought on by the extensive travel) while working my ass off in the lab to try to fix my cryostat. I failed, but at least I know what’s wrong now and have a pretty good idea of how to fix it. This morning I attempted to go biking with Martin and Sirena, but as it’s 90F today in Berkeley and my ancestors are from a foggy island in the middle of the North Atlantic, by the time I got to the top of the first hill I was dying. Luckily there was a water stop at the top of the hill, and I totally drenched myself with water. When we started riding again, I found that I was no longer dying, and in fact I felt quite cool. I finally saw for myself why people whose ancestors came from somewhere warm (and hence actually sweat a significant amount) can survive exercising when it’s way too hot out. It’s evaporative cooling, baby!
