Very Interesting. It is fun to see brilliant young (or any age) minds at work.
A classmate and friend of mine went to CalTech. He was attending there when the Slinky came out. A group of students figured out, just how much energy, etc. it took to make a slinky go down the steps to one of the buildings. There was quite a bit of publicity about the the thing. I suppose because Slinkys had become so popular and interest was focused on them.
First of all you have to be smarter than the machine.
