Newton’s Notebooks Digitised — wonderful for historians, professional and amateur. I love (a) his handwriting; (b) the pages full of long division that remind us what an amazing time-saver the calculator and then computer was; (c) use of “yn” for “then (the y is actually a thorn, pronounced “th”, and it’s from this that we get “ye”, actually pronounced pronounced “the”). All that and chromatic separation of light, inverse square law, and alchemical mysteries.
