母校を訪れる (Visit to My Alma Mater)

　昨日午後、京大理学部物理学教室を訪れた。私の旧職場の放射線施設を使う共同研究をしている大学院生の担当教授に、実験結果についてのコメントを求められてのことである。思えば、学位取得後も理学部構内へは何度か行ったが、現在の物理学教室の建物に入ったのは初めてである。構内をまっすぐに南北に貫く道に沿うイチョウ並木は、まだ十分には秋色を呈していなかった（写真）。それでも、木々は私の学生時代に比べて、ずいぶん背が高くなっており、その下を歩くのは、いかにも心地よかった。

Yesterday afternoon, I was invited by a professor at Department of Physics, Kyoto University. The purpose was to provide comments on the experiment made by one of his graduate students at the radiation facility of my former work place. I visited the campus of Faculty of Science, Kyoto University, a few times after my getting Dr's degree, but this was the first time to enter the new building of Department of Physics. There is a campus road going straight from the gate to the northern end, and the road is lined with Ginkgo trees (see the above photo). Leaves of the trees were not yet showing full autumn color. However, the trees were much taller than my student days, and I felt it quite pleasant to walk under them.
