I first saw these wonderful snowflake drawings by Isaac Newton, um, someplace on the internet. When I wanted to use them in my book Isaac the Alchemist, Secrets of Isaac Newton, Reveal’d, I  emailed all sorts of experts asking if they knew where in Newton’s many, notebooks the snowflakes might be found. No luck. So I sent a tweet to the Cambridge Digital Library (@CamDigLib), and within minutes got this link back.

Newton did all sorts of cool drawings. It would be great if there were a book of them so people could just page through and find them easily. On, sigh, actual paper.  But in the meantime, I will post a few more of my favorites.

(MANY thanks to the Cambridge University Digital Library for letting the public share these great images online.)
