Some of you enjoyed the recent and continuing discussion on Lens Equivalents. Those people who find the science and technology behind photography interesting may enjoy my new BLOG: photophys.com
I am posting my new book (tentative title) "Science for the Curious Photographer" chapter by chapter in hopes of getting comments and criticisms. The first three chapters are now online. In a few weeks I will post more chapters. The later chapters are much heavier, and I need advice about the best way to represent physics and math to a general audience.

Charles,
This is shaping up to be a really interesting book for the layman. Your first 3 chapters are excellent and I hope you can maintain the clarity and interest in subsequent chapters, especially with regard to the complex mathematics which is sometimes an obstacle for some of us.
The only criticism I can make is with your introduction of the concept of the pixel in chapter 3, which you describe as the smallest element in an image. I think you should amplify on this because there are a couple of competing concepts here. One such concept is that the pixel represents the smallest 'picture' element, and a 'picture' element consists of a red, green and blue element. Such confusion has manifested itself in descriptions of the pixel count of the Foveon type sensor in the Sigma SD9 for example. Is it a 3.3mp sensor or a 10mp sensor?
My standard definition TV set (or any SVGA monitor) has a resolution of 800x600 pixels, but each of those pixels has a red, green and blue element. I think you should dispel any confusion about this right from the start.
Best regards for the project.
