You, sir, are the person that doesn't allow me to sleep soundly at night (look at my signature!). Double irony twist M Night twist alliteration- I don't know anymore
What makes you say that? The fact that I called Fermi "best event," or that I proctored it at MIT?
Do you guys have any idea what I should use to study?
Personally I've learned that having an intuition of the scale of things helps a lot more than knowing random trivia in general. For example, vaguely knowing about something (ex the Eiffel Tower), can you reason a decent guess of its height? Besides that there are certain numbers that are useful to know - masses such as that of Earth, Sun, etc, volumes of the great lakes and oceans, etc. Best of luck!
