Two astronauts are, 6.207 m apart in their spaceship, speaking to each other. The conversation is transmitted to Earth via electromagnetic waves traveling at the speed of light. The time it takes for the sounds waves to travel at 343 m/s through the air between the astronauts equals the time it takes for the electromagnetic waves to travel to the...

Recently several hockey games in the Olympics were decided in a post-overtime shootout, winning by just one point. Statistically, I would say that the two teams are actually identical. Yet one gets the gold, one the silver... or one moves on, one is eliminated. In speed skating, the difference between first and second was in 1/1000s of a second. In...
