Electricity and magnetism run nearly everything we plug in or turn on. Although it’s something we take for granted‚ it has taken hundreds of years of experimentation and research to reach the point where we flick a switch and the lights go on. Ancient Greeks knew rubbing amber generated static electricity‚ but they didn’t know why. The Greek word for amber is elektron. People knew about electricity for a long time. Ancient Greeks noticed that if they rubbed a piece of amber‚ feathers would

The Law of Navigation Law Number Four is called “The Law of Navigation.” The by-line for this chapter reads‚ “Anyone can steer the ship‚ but it takes a leader to chart the course.” That by-line reflects something that anyone can beat time‚ but not everyone is a conductor. Anyone can learn how to play a piano but not all will become a pianist. Everyone can learn to swing a golf club but not everyone can become a golfer. Regarding conducting‚ more than a few famous conductors have said that they can
