You might remember my discussion of bio lab in my last post. About the time my prof mentioned you need to read a lot of lab reports to know what you like, she also mentioned you need to read a lot of reports to learn something else: What's been done.
When doing a write up, you need to acknowledge what's been done before. If you don't keep track of what's been done around your subject, your research could end up looking totally derivative and useless.
It's sort of the same thing with books. Sometimes the same idea occurs to three people at the same time (I've heard of it), but if you never read, you'll never know it's been done before or how to make your book original in comparison.
Books are good. Books are fun. Books are context.
Go forth and read!
