Bests & Worsts Reviews from Amazon

I am a Biology Professor and I am learning Astronomy as a hobby. I've read countless books on Astronomy, but not a workbook. I love this book!!! I'm on the 3rd chapter of the book, and as of now I've don all the exercises up to this point. Yeah, I couldn't wait 'til I was done to give the review, and that's how excited I am about this book! I read all the reviews about this book before I purchased it. The reviewers who gave it low ratings due to the math or having to know prior scientific knowledge are correct. They are not lying. It helps to know the basics on metric conversions and knowing how to manipulate formulas. Most people hate math! I learned to respect it because math confirms everything, and math helps you to understand science better. I encourage you not to skip through the math without giving it a try. It will help you to understand the sky, your telescope, light waves and your lenses much better. The more you understand, the deeper your appreciation will be for the science of astronomy even if you're only doing it for a hobby (and it aint that serious). When I began the hobby of astronomy 10 ten years ago, I would skip through the math. I wanted to see the planets and the moon and call it a day. Now I want to know everything!!!! Since I've become more hungry for knowledge, I love astronomy that much more! Buy this book. Everything is well explained. Take your time with it. You will feel more empowered and more confident in the science.
