About

Here is the blog written by me, UlyssesZhan (pronunciation: [juːˈlɪsiːzˈʈ͡ʂán]), a.k.a. 有丘直方 (pronunciation: [jou̯˨˩˨t͡ɕʰjou̯˥ʈ͡ʂʐ̩˨˥faŋ˥]). I share interesting thoughts of mine here.

Some of my basic (and improbably changing) information:

I am interested in physics, programming, and mathematics. I am also interested in other academic fields such as economics, linguistics, etc. although I have not studied them seriously. For games, I play rhythm games, puzzle games, and PvZ series games. I am a video creator about those games on video platforms. I am happy if you want to talk with me about those topics that I am interested in.

The icon of this website is my avatar. It is drawn by myself. If you want to use it, the user terms and the downloadable files are available here.

This blog may be updated at an extremely low frequency because I may be busy. If you want to prompt me to update my blog (which is a really rare occasion), contact me. I will be happy if I know there are people interested in my blog!

Note that if the browser tells you that my site is trying to run some dangerous scripts, it is just loading necessary scripts for mathematical equations (such as Equation \ref{least action} shown below) to be rendered in my pages.

Finally, I would like to tell you what I think is the most beautiful equations of all. Yes, it is Hamilton’s principle

\[\begin{equation} \delta\int\mathcal L\,\mathrm dt=0. \label{least action} \end{equation}\]

I will never tell you that I was actually to test whether mathematical equations can be rendered correctly.
