No overtime day

Today is a no overtime wednesday and the library in my office was closed, so I left my office around 17:00. Now it's 18:30, and I already have came home. 

In my working hours, I studied using a textbook about my new research project. I had expected that the stdy doesn't work , because I hadn't studied mathmatics and physics long time. However, the learning was more smooth than I had expected. I hope to make more progress tomorrow!
