I'm now in Bochum, my first destination. The climate is pretty good, and I'm fine. The only, but big problem is that my computer doesn't connect to W-LAN network...! So I'm writing this in a mediacafe, but of course I can't read and write Japanese charaters...orz. I don't know if this situation could be improved during my stay in Germany. Therefore if you need to contact to me, please write an email to the adresses at yahoo! or google, with alphabets only. It's really hard to do without Japanese, but I've decided to enjoy this rare experience. // Today afternoon I'll go to the Rule University to meet to the Professor Pulte, whose work seems to me highly important for my current research. Actually his book was a guide for my historical study on the principle of least action, the subject of my master's thesis.
