Writing progress, new ideas

I’m in the middle of working through my new work in progress, tentatively titled “Don’t Ask Me Why” and here I’ve been struck with another idea — one that won’t seem to leave me alone. It’s to write that book — quite possibly for kids — on the history of mathematics that I looked for and couldn’t find when I started writing my math poem collection.

The problem is that it’s going to be a lot of work, and involve a lot of research. I’ve tried telling it “down, little idea,” but it won’t cooperate.
