Clay Shirky has an amazing Ted Talk video. It is about what the computer science community can do for democracy. This is the future of legislation, I hope to see it in place in my lifetime. The larger aspect is this type of distributed work will be at play for more than just the open source community.
Everyone is jumping on the coding bandwagon. Yes those jobs earn more and everything will need to be programmed. The VCR (now DVR) is not so simple any more. And more and more things are on the Internet (like it or not). Many of the programming concepts are truly based in math, taking a large problem and breaking it down in to smaller and smaller parts. Which is why i think this is funny.
Magnets are fun and exciting. Real magnets are from iron or electro magnets. In physics class I remember learning that magnatism does not exist and it really is changing electron fields. Yes, that is true. What is really cool is that to fully explain why magnatism exists, the new pysics fields of special relativity and quantum mechanics are needed. Both only recently worked out in the last 100 years. And we have been using compases for a while. Wow and awesome!
