<<If you know very little about general relativity (even though you might be a great graphic artist!) how can you write a small book about black holes for middle school students? Are you partnering with a physicist who is well versed in gravitational physics? Are you an expert in that yourself? If not, how good the students get a good book?>>
First, thanks for your reply and the recommendation of Lawrence Krauss. I will see if I can get in touch with him.
You ask a very good question about how good the book will be. The book (really a reader) is twenty pages and 2000 words, plus pictures. I've been studying black holes for a year now and believe me, there's enough there for 2000 pages even for the average graphic artist. It's very hard to write about this subject without getting into the tall weeds, and some concepts are difficult to wrap the brain around. How do you explain general relativity in two sentences for a 10-year-old? That's the challenge. I'm working on the first draft of the manuscript, which will then go to my editor who's an expert in educational writing. It will then indeed be fact checked and discussed with a physics expert. And then the book will be leveled for the appropriate age, and then, most likely, be fact checked again. It's a long process.
Although I don't have a deep understanding of the physics, I have a reasonable comprehension of the facts and concepts. I do understand time dilation, the equivalence principle, and even a bit of the Lorentz transformation, but for the finer mathematical details I get lost in the equations. And yes, I did watch all two hours of Dr. Physics. Even grasped some of it :-) https://www.youtube.com/watch?v=foRPKAKZWx8
The purpose of the books isn't to provide a comprehensive study but an introduction. Hopefully, kids (and maybe even adults) will find black holes and relativity as fascinating as you and I do, and inspire "Hey Dad, I bet you didn't know about this . . . !!!"
Thanks again for your help and best regards,
