Charles' Presentation Synopsis: Analog vs. Digital: Rhythms of the Natural World, our Struggle to Compute Them, and Windows 8:

If digital technologies are so great, why do we increasingly hide digital computation under fluid and bouncy user interfaces? If analog computers are so lame, why are they also so clever, so elegant, and so fascinating? Join Charles Petzold in an exploration of analog vs. digital computation of natural processes in a talk that connects Vannevar Bush’s Differential Analyzer of the 1920s to Windows 8 and other modern user interfaces.

Charles' Bio:

Charles Petzold has been programming for Microsoft Windows since 1985 and writing about it nearly as long. He wrote the first magazine article about Windows programming, and one of the first books on the subject. That book, Programming Windows, is now in its 6th edition, having recently been entirely rewritten for Windows 8. He is also the author of books on .NET programming, and Windows Phone 7, as well as two unique books that explore the origins and underpinnings of digital computing: Code: The Hidden Language of Computer Hardware and Software and The Annotated Turing: A Guided Tour through Alan Turing’s Historic Paper on Computability and the Turing Machine. He is currently writing a column for MSDN Magazine on DirectX programming, and working on a book about the roots and concepts of analog computing.

The Venue: (address above: Note - this is the area of Newport Beach that's practically touching Irvine) Parking is FREE: The Gate to the Parking Area Goes Up at 6:00pm. You can see photos of the venue here:

Please be courteous and leave as close to 9:00 pm as you can, unless you are a clean-up volunteer. We have a lot going on and we need to stick to schedule. Therefore, there will be no bio-breaks. If you need to go, quietly leave the room and return.

    Was there a video record of Charles presentation?

      No, unfortunately. He made it for us, so he doesn't want it online.

      Ok, I was going to show my daughter who is studying calculus right now. Oh, well. Thanks

    Awesome meeting! Finally got to meet Mr. Petzold after all these years of reading his books. Thank you to those who organized the meeting. I'll definitely attend more.

    I cant seem to think out of the bits... :-

    Great presentation, going to get me some Legos to build a Differential Analyzer, or get the code to those awesome 3D simulations.

    I enjoyed Mr. Petzold's presentation very much purely because I enjoy everything that has to do with math and physics and I think his 3D work was amazing! It was also very well presented! I think bits and digital machines are way superior though :)

    An honor to be actually having fun with such an amazing man. He's got a great personality, is as humble as can be, has a great sense of humor - it was just the coolest couple days I've had. His presentation was nothing short of genius, leaving us with new perspectives on life and computing. Very much like Charles to leave a thought-provoking end to his presentation - for us to ponder :-) I'm looking forward to having him return.

    Great review of computer development plus Calculus 101 :> The animation is amazing with Direct3D.

    Presentation was outstanding. Intersection of differential equations & 3D graphics. Reminded me of the original PBS James Burke series 'Connections.'
