# How to suggest new entries to David Wells' “Book of Curious and Interesting Numbers?”

This book. I'm sure many here, if not most, have read it. If not, I recommend it. It's great fun.

Is the author even alive? I'd like to suggest a few entries that are not in the latest (1997) edition. For example, 0.73908513321516064... which is... nah, I won't tell. See if you can find out what this is.

I haven't found any contact information, and his name is so common any web search is maddeningly cluttered.

@JCC: I was wondering, did you know that it has a name? It's the Dottie number. – mixedmath Sep 15 '11 at 20:04
If there hasn't been a new edition in 14 years, I wouldn't hold my breath waiting for one. Are you aware of Plouffe's inverter, pi.lacim.uqam.ca/eng It handles your .739 number quite well. – Gerry Myerson Sep 16 '11 at 1:48

Well, the first page of Google hits for "david wells" math contains http://www.thetutorpages.com/tutor/david-wells-London-maths-tutor, which is the guy you're looking for. There's a contact form if you want tutoring, but perhaps you can try using it just to get in touch.
