Now it's back to work in Taiwan. I still had several administrative issues to take care of this morning (health insurance, travel reimbursement, opening a bank account, etc.), and it made me stop and estimate the total amount of effort that it has taken to set up this sabbatical. I'd guess we expended a person-month of work to book travel, sublet our house, move in, set things up here, enroll the kids in a new school, etc., etc. It's pretty daunting considering our planned stay here is slightly less than a year!
I've had really good luck with jet lag in the last month. I adjusted fairly rapidly from Pacific to Taiwan time (-9 hrs), then to Spain (-6 hrs), and now (seemingly) back to Taiwan. I find melatonin works very well for me, although different people respond differently to it. (I learned about it from a Japanese physicist who travels a lot.)
Below are some photos of my office and the Institute of Physics here. I've gotten in the habit of taking photos all the time using my iPhone. As I mentioned in an earlier post, it helps me remember what I've been doing during this life. ("The days are long, but the years are short.")
