Retaking calculus after six years has proved an odd experience. Concepts that came to me so easily back in high school are much more difficult now. On the other hand, those concepts that I did not learn then or that I did not understand fully come much more easily. I am spending the next four days studying for my final. I am using my old technique of creating a comprehensive study guide.
Concerning math, I listened to a pretty cool podcast from In Our Time with Melvyn Bragg which discusses imaginary numbers. Enjoy.
