Why am I studying in “Double E”? Einstein once said “The only important thing is not stop questioning.Curiosity has its own reason for exisiting”. Since I was a child, I have been curious about everything. I was wondering how TV works and how computer works and many other amazing machines. I want to figure out why I just put a button then the TV will show me the show. As a result of the curiosity, I decide to study in Electronic Engineering to find the chamber of secret. After four years training, I start to understand how to build these machines. The most interesting thing is I realize how to write a complicated function into a small chip, and make it out just like TSMC, the most famous company in Taiwan does. I have learned not only the secret I want to know but also many other theories. At the beginning, I felt so bored to study in thoes books. Why I should learn so many theories? And what can it be implemented for the rest of my life? When I keep studying in master degree, I gradually found thoes answers. Those process is to make our brain facilitate. If you can’t figure out even with books and teacher’s class. How can it be possible to make you think a great new theory in the future? And I thought the most important thing is mathmatical justification. Even if you come up with a great idea and have a good result, you still can’t convince everyone. They won’t accept your theory until you prove it through mathmatical justification. This is what scientists do in their research.
