I went to a free presentation about Japanese moving dolls provided by the library. The library is pretty cool, with an “International Community Center” on the third floor.
I sat next to a German lady that is doing post-doc molecular physics research at a research place here in Okazaki. She is working on a molecular spectroscopy device. That conversation made me realize that I can talk about molecular physics better than I do small talk.
