Matt Westfall describes how math is applied to a 10' satellite dish lined with mirrors. His math classes will then calculate the equation of a cross section of the satellite dish and will calculate the exact focal point of light reflection. Afterwards, they will cook hot dogs on the dish.

  • "Ancient Greeks were far more techy than your teachers/professors will admit"...I disagree...If anything, teachers stress the advancements that the Greeks, Romans, Egyptians, etc. made through the years which is the main reason why they are still referenced 2-4,000 years later. And yes, obviously they used different technology than in this experiment, but we had to keep to a very strict school budget and were teaching the math behind it and not trying to re-create the Archimedes myth.

  • nothing could stop it....except clouds :)

  • real nice equation too bad we don't know the what the varibles stand for!

  • 50,000th viewer right here!!!!!

  • @pingpong1525 an ever bigger one could stop this one

  • @Ryboy1381 What did they do?

  • @pingpong1525 Not to worry. Just use an electric, gas, wood or coal oven as a source of heat radiation.

  • @Ledamonster yea like technology is really making this world a better place...

  • @pingpong1525 this can be done very cheaply. It has nothing to do with budgeting; thats only a cop out for lazy teachers who care more about their pockets than their teaching.. these types of "recreations" are indeed very helpful in the applied and empirical sciences.

  • here is the way you can use what you made. send the sun light into a cone shape focal point into mirrored tubing and send that sun light down into a mirrored box where solar panels would be spinning to keep the solar panels cool or put in a cooling system but i think that will be a problem control the sun and make it work for you dish has to have robot arm to follow the suns path
