Cancelled due to Hurricane Sandy. Sorry!
If you've been to the London Science Museum, you've undoubtedly seen this gorgeous piece of hardware built 140 years ago:
Today we classify this as a special-purpose analog computer. You might know what it does, and you might even know how it works, but I suspect you're not aware of the role this machine played in the 19th century debates over Charles Darwin's theory of evolution.
This machine is the subject of a book I'm working on and which I hope to publish sometime before the 2020's. Until then, all I can offer is a summary in the form of a talk with pictures and animations that I'll be delivering at my favorite place in Seattle, Ada's Technical Books, on October 30th at 6:30 PM.
I'm going to be in Seattle that week for Build, and if you'll be at Build as well (or just in the Seattle area), drop by, hang out a bit, and perhaps even buy a book.
For a little more information about the content of the talk I'll be giving, check out the Microsoft Press Blog.
