Book Project: How We Know What We Know about the Universe

There are many popular books describing what we know about the universe.  What we know about the universe has developed from asking questions like: How old is it? What are its size and shape? What is it made of? How did it form and from what? How has it changed with time? What will happen to it in the future? But how do we know the answers to these questions?

I am writing a book, for a general audience, about how we know about the universe. The challenge is to describe how we get from what we can observe and measure—simple things like apparent brightness and color, apparent size and shape, and position in the sky—to a detailed physical understanding of what we really want to know about the universe.

I will describe the process of designing and writing in a new style, not a journal article or a textbook, for a much broader audience than we usually encounter every day on a college campus. Audience members will assist in choosing a better title for my book.
