One of my fondest memories was accompanying my then partner to another city, so she could use their particle accelerator for her research. I didn't get to go anywhere near the accelerator and so I just wandered the city, had dinner and whatnot. It was mostly operated from a command line and she was run through how to operate the equipment and do her tests, then left pretty much to her own devices with the accelerator. At a bit after midnight, I get a couple of text messages, her firings all went to plan, but she can't figure out the command line in order to archive and copy the data to her personal drive. Cue a 1am phone call trying to figure out what the operating system was and what commands were at our disposal. Thankfully it was unix based and everything went smoothly, but it was fun and I was glad to feel useful on the trip!
