I would like to understand beautiful mathematical structures.

Soap bubbles are round, for the surface area to be minimized, and such phenomenon is commonly called the variational principle. It is deeply related to differential geometry and partial differential equation in mathematics and I am studying on the differential geometry side. It has been more than 200 years since Euler’s prominent study of elastic curves, but there are still new discoveries to be made.

Nowadays, most computer displays are LCD monitors, but when I was a graduate student, there were many CRT monitors, and the one assigned to me was also a CRT monitor. However, it did not suit me and my eyes began to hurt immediately, which caused me great difficulty in conducting research using computer simulations. I asked the university if I could somehow get an LCD monitor, but the request was rejected out of hand and I was at a loss. It was then that my mentor bought me an LCD monitor personally. I was very grateful and will never forget it.
