Every time your phone puts a blue dot on a map, it is quietly allowing for the fact that time runs faster on a satellite twenty thousand kilometers up than it does in your hand. Left uncorrected, that tiny difference would send you kilometers off course within a day. Physics is full of facts like this: claims that sound like riddles until you see the reasoning, and then turn out to run the machines you use every morning.
Without a single calculation, you will follow the arguments that took people from Aristotle's carts to Einstein's clocks: why a rocket needs nothing to push against, why a hot drink never warms itself up, how a spinning magnet lights a city, why the sky is blue, and why an electron can behave like a wave. You will also meet the hardest question physics has handed to citizens, what to do with the energy locked in the atomic nucleus, and be ready to weigh claims about seat belts, heat pumps, free energy gadgets and nuclear power with a clearer eye.
