As I told you guys in last class, some advices about the academy will be written in english. This is because English is a very important language in general science, specifically in Astronomy and Astrophysics. So, it's a must that you practice it a lot from now on.
Well, I want to share with you a pretty nice video about distance in our universe that it's going to be quite useful in the "Magnitude Orders" class. So please, give it a try someday before the class day.
