Differential Equations, attic fans...and lots of caffeine

I've been studying diligently for my Differential Equations exam this Thursday. I am exhausted because all last week I was studying for my Bio exam. On top of that I couldn't get to sleep last night...Sunday nights have always been that way for me. I just can't ever seem to wind down. So when I couldn't fall asleep I finally got up and finished all the laundry, did the dishes and played with the kitties (who were having no problems sleeping but why should they get to if I can't??)

I finally went to bed and fell asleep sometime around 3:00 AM. My alarm was set for 7:00 and boy was I tired this morning. I am hitting the caffeine hard today. One good thing about yesterday was the weather. There was a nice breeze and I think the high was only in the mid-low 70's. I had the windows open all day and night. It was heaven. And of course the kitties love to bask in the sun on the window sills. Because my house is so old (1943) there is a neat little contraption called an attic fan. It's centrally located in the hallway, pretty much where an actual attic would be. My parents had to explain to me what it was when I first moved in. Anyway, last night even though I had the windows open, by nightfall there wasn't as much of a breeze and I felt a little warm. All that cool night air was being wasted! So I flipped on the attic fan and within 5 seconds the whole house was fresh and cool. Granted, it's a pretty loud sound so I knew I didn't want to keep it on all night. But what a great invention!

Ok, I am off to work on separation of variable, Euler's method, linear systems, eigenvalues and equilibrium point analysis...sounds exciting, yes?

Hopped up on caffeine,
