search engines

Okay so I'm not retarded and I do know how to use search engines. But I realized just how useful they can be. Yesterday I was studying for my kinesiology final and was very frustrated because I didn't know what the letters in the equations stood for. I searched them on yahoo and was surprised at the ease of finding the information I needed. I even found links to websites that broke down the equations so they were easy to understand. I can't believe I didn't think to do this earlier in the semester when I would try to study for kinesiology but didn't know how. Search engines are definitely one of the most useful tools on the internet. They can find you links to virtually anything you search for. It truly is amazing.
