Happy π Day!

Happy π Day! And Albert Einstein was born #OTD 147 years ago!
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".
"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world."

https://www.gutenberg.org/ebooks/author/1630@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.

@gutenberg_org @capnthommo https://brilliantmaps.com/wp-content/uploads/2015/01/dateformat.png Only the US uses that format. The rest of the world doesn’t. Which was the point. See you on the 22nd of July!

https://www.gutenberg.org/ebooks/author/1630@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.

@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

https://www.gutenberg.org/ebooks/author/1630And 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...
