Welcome to a blog written by a Japanese superstring theorist! I'm Koji Hashimoto, a professor at Osaka university, Japan, playing with "D-branes" everyday.
Are you interested in superstrings and like to know more about it? If your answer is yes, unfortunately, my blog is not the one you like to read... I have my own Japanese blog and have been writing it for almost ten years. If you are Japanese, please try reading that (the address is http://d.hatena.ne.jp/D-brane/). You will immediately find that my blog is very different from typical blogs written by physicists. My Japanese blog is only a huge collection of description of my daily life, and my feelings. I have written whatever I felt. I haven't tried to write anything to "explain" physics to readers. Probably you might be disappointed, if you expect some nice articles on recent developments in superstring theory.
My Japanese blog started when I was a post-doc at Santa Barbara, ITP, in 2001. It was my first experience to live outside Japan, and I started writing a diary on my Web page just to inform a professor in Japan (who was a supervisor of mine when I was a graduate student at Kyoto) that I was doing fine out there. Soon after I started it, I recognized that the diary was very helpful for myself, to keep things in a written memory and to remind me of what happened to me, what annoyed me, what made me laugh, and what I felt happy about. That's why I continue writing the blog for about ten years. I will continue this style, and in case you like reading such a daily life of a superstring theorist, you are always welcome to read my blog.
The name of the Japanese blog is "Playing with D-branes". The D-brane is a very important concept in superstring theories. But you don't care about it. More important is the word "playing". Some of you might feel that the word "playing" is misleading because it may remind you of some spare time, not working. But in fact my feeling is really close to the word "playing." This can be easily understood when you see kids playing. When kids are playing, they are most serious. When kids are at a desk and forced to do some homework, they are not serious. This is what I mean. I am very serious in playing with D-branes (though I sit at a desk to play!). I love D-branes and superstring theories. So I am playing. I am a happy man, in the sense that I can work while playing. So, as you can imagine, my diary will be a collection of what I feel about things what happened around me, when I play with D-branes.
Thank you for reading this very long introductory remarks. Please jump into my blog if you feel you like to know a little more about a daily life of a superstring theorist.
