meanfreepath2 more things:
We were venting the vacuum chamber with N2 as we needed to change an electrode (plain air has too much water vapor, which is very hard to pump out). Then we find the N2 bottle empty. It'll take a few days for another bottle to come in. If only I had checked the gauge a few days back...
There's also a broken chair in the office, which I don't usually sit in. But when our PI had to go over some stuff with us today, I took that chair, and before long, the seat separated from the body of the chair and I ended up on the floor. Wasn't hurt at all, but these things are just silly.
