I left my apartment at 4 AM for my office in the institute.
I checked my e-mails, finished working with some documents, and went to Kofu station by bike for two meetings scheduled to be held in Tokyo.
There, I carried out some experiments using the Russian instrument I am interested in. I explained the information I needed to Russian and Japanese operators of the instrument. Then they started the experiments. I was there with them and left the building at 2 AM.
The discussion ended at 5:30 PM. It was fruitful.
The students and I had some beer with pork and chicken brochettes in a bar.
I left my students and walked to kanda Station.
Because of an accident, Chuo line was not available for a while. The train left after a delay of 50 minutes and ran very slowly. I arrived at my apartment at 10 PM. I was very tired.
