Get Rid of It
I'm buying new furniture for my place and this has prompted me to do a major purge. It is obvious that I have far too many books. The Wodehouse collection is sacred, but I can safely recycle my 1984 undergrad textbooks.
For some reason I really like calculus and did pretty well in it. I even took some advanced Math courses and I'm not really sure why, but they probably had some practical applications back then. Differential Equations and Boundary Variables was a little difficult. There is a "Hello Kitty" sticker on the side of this book - a reminder to me that this book isn't for kids and I better take it seriously or I would fail. No comment on whether I actually passed this one or not however.
Why learn this stuff? Any practical application? Of course!
These particular equations examine ecological situations involving two species, one of which preys upon the other. In the absense of a predator, the prey grows without bounds, in the absence of prey the predator dies out.
These equations are very simple and there are ways of making them more realistic.
I also used this type of equation to study excitable neurons in the Physiology lab.
Maybe I should keep this book. Could come in handy someday.
Just kidding - it's gone; I'll dump it off at some used bookstore. I don't think anybody would buy it on Ebay.
