We started today's class by finishing the last 10 minutes of the video we started yesterday. While that was happening I moved about the room checking everyone's homework. After that we spent a bit of time talking about GPS and how it works. A website that helped us in our understanding quite a bit is called How Stuff Works. That short video lead to quite a good discussion on triangulation, GPS, radiowaves, the surface of the earth and a host of other topics. Well done everyone.
After that we went over some of the questions from yesterday's homeowork. In particular we went over question 4 and 7 and I asked you to finish up to question 12 for tomorrow. Notes from today's class can be found here.
