Just an update

It has been a while since last time a posted something. The new semester is a little bit more crazy than I thought it would be.

As a TA, I do have a lot more work to do than what I had to do as an undergraduate, though the work is not really directly study related.

A little bit tired, but so far it’s still acceptable. Right before I typing this update, I was doing my quantum homework and digital electronic homework. Originally, I wanted to some research, but realized I should probably focus on regular school works first. I don’t remember when was the last time I did homework on a Friday evening.

I guess the way I look at physics is different now: I am a Ph.D. student, which means I am doing it professionally.

Anyway, so far I quite enjoy the process. Recently, I keep using the word “quite”. I may want to change this.

At the end, just want to show one of the circuit I simulated by using LT Spice. It’s a rectifier that is followed by a low pass filter.
