Life is really unpredictable I must say, as I would have ended up working at CERN for my PhD under the same group as my master's lab. Due to my eagerness to try out something different and also my tendency of moving around (like from Osaka to Kyoto and to Tokyo in Japan), I have gambled my future to do my PhD at a place unknown to me at the time, Zurich in Switzerland. And of course I am glad that I have made this choice as it has changed me tremendously in terms of my perspective about physics and society and also extended my network over the world.
We had a great time having lunch together talking about our labmates when we were at Tokyo. It is pretty amazing that everybody is still working towards what they planned to do a few years back, and nothing is stopping them right now. This is truly scientist mentality or Japanese tamashi?. :) After the lunch, out of the sudden, we walked towards the Geneva lake and entered the public swimming area. And guess what? We rented swimming trunks and jumped into the lake! This is perhaps the 2nd random stuff I have done after the 5-minute-decide-to-go-Vienna trip. It was freaking hot these days and I was completely relaxed after the swim.
