When I mentioned carrying out computational processes with a room full of dominoes, I wasn’t kidding. Matt Parker is planning to build a domino computer at the Manchester Science Festival at the end of the month. The Manchester Science Festival blog has a nice writeup explaining the project.
Here’s a video of Matt explaining how a domino “AND” gate works (two chains of dominoes come in, and one goes out; the outgoing dominoes will fall only if both incoming chains do). Unfortunately it seems I can’t embed videos on this blog, at least not without giving wordpress some cash =(, so you’ll have to actually click that link to watch the video, but it’s totally worth it (trust me).
I wish I could go see it, but it’s a bit far for me. Any Math Less Traveled readers in the UK who can actually go watch the computer in action and report back?
