Now it can be revealed: For a long time I have had the idea for an epic TV-reality show a bit like "Survivor" or "Naked and Afraid" on steroids. It would have three or four teams in competition. The premise is to start the teams with almost nothing (Okay...Maybe a hatchet), and the winner is the first group to transmit a radio message within a given frequency range declaring that "We win!". The only set-up would be that the groups would be restricted to a given geographic range (a large range), and that the raw materials (e.g. iron ore, coal) to accomplish the goal would be somehow made available within that range.
A single "season" would span years. In all likelihood, none of the original players would make it to the end.
What is fire?
What is electricity?
What is gravity?
How do we know how big the earth is?
How can I conceive a time span of a million years?
