Barcelona-based independent publisher Kronecker Wallis is putting out a reissue of Newton’s Principia with very good graphic design. (Link goes to Kickstarter, but it looks like the plan is to sell it through normal channels as well if this Kickstarter, well, kickstarts it.). 45 euros including shipping, a good deal for an object of this quality.
I’m reminded of Byrne’s graphical Euclid, although this is not the same sort of project – Byrne replaced the text with graphics, and this is about making the text look good and be a pleasure to hold and read. Are there any other similar editions of mathematical classics? (Given our history of neglecting our history, I’m not particularly hopeful, but would love to be proven wrong.)
