I'm master's level graduate, and my major is traffic engineering.
But now My job has nothing to do with it.
I have liked mathmatic and physics since I had learned them for the first time.
So I headed to field of science and engineering without thinking deeply
and entered the faculty of engineering at university.
I majored in civil engineering for my undergraduate degree
and traffic engineering for my graduate.
Especially I learned a partial differential equation.
I made use of the skill I learned there at my previous job as CAE engineer.
CAE stands for Computer Aided Engineering.
It's even difficult to explain it in Japanese so it's impossible in English.
In a word, It is about an area of computer simulation.
Now, I have never made use of it because I'm an administrative staff at university...
