    Isaac Newton used infinite series to compute π to 15 digits, later writing "I am ashamed to tell you to how many figures I carried these computations".

    @gutenberg_org Hang on, are we talking about Taylor or McLauren series here? Just curious about what the state of the art was at the time.

      @gutenberg_org sorry. Pi day in this country is not until 31st of April. April having only 30 days. So of course piday will not happen.

      @capnthommo @gutenberg_org I think we're still allowed to have maths-based fun even if the date thing doesn't make much sense to us 🙂

        And now we take pride in how far we can calculate pi.

          @muddle we need to access this book to get a proper answer https://books.google.com/books/about/Pi_Unleashed.html?hl=pt-PT&id=QwwcmweJCDQC

                  @muddle Should be Taylor series as mentioned here (as far as I remember): https://www.gutenberg.org/ebooks/76404

                    @gutenberg_org Thanks! I somehow thought that the Taylor series was somewhat later than Newton's work on calculus but I guess that they were contemporaries and Newton would have been aware of Taylor's work (as well as earlier formulae for pi).

                    This could become a bit of a rabbit hole, but I'm reminded of Fabrice Bellard's more recent calculations (probably since surpassed?) and wondering what new techniques he used...
