Ice Age I

Oct. 6-08

This is the time, where I would go around and ask people: "What would you do if this is your last day on the earth?" Whenever you hear me talking about things such as "the end of world" or "the coming of the ice age," then there is probably a term test approaching. I am starting to get tense. Just to relax myself, I will watch a horror movie tonight and begin my test study tomorrow.

Today, we have examined some questions on Fibonacci sequence and binary trees. I have come across the Fibonacci sequence several times in my life, but I never liked it. To make things worse, I didn't get the proof of F(n) = (phi^n - phi_hat^n)/sqrt(5). After the lecture, I stared at the slide trying to find out why phi = (1 + sqrt(5))/2. Two hours later, I finally noticed that I could just go ahead to solve r^2 = r + 1 to obtain the root (this was written on the next page of the slides.) Obviously, I was losing my focus and needed to pull my mind away from CSC236 for a while.
