Why do we need physics if we don’t intend to become physicists? Why fill our heads with complex definitions, intricate formulas, and confusing explanations? How can we even remember all this and fit it into our minds? Countless generations of schoolchildren have asked themselves these questions. How many graduates still recall their school physics lessons and homework with horror and disgust? How many are left with only fragmented names of laws and snippets of definitions in their heads.
Understanding that physics is not so difficult, but incredibly interesting and even thrilling, will be aided by this book. Here you will not encounter problems or formulas, but you will find simple and clear explanations of laws and examples of how these laws work in phenomena and objects that surround us everywhere. Why do cracks in the asphalt turn into potholes in winter? How does a GPS navigator work? Why can you skate very fast while exerting very little effort? How does a bridge withstand the weight of a freight train?
The laws of physics also operate within our bodies: when we sleep, walk, swim, and simply breathe. Did you know that our nerves and brain work thanks to electrical impulses? Have you ever thought that we have a sense organ capable of perceiving electromagnetic waves?
Knowledge of physics helps us take care of our own safety. The book will explain, for instance, why you should not stand at the edge of a platform where trains pass, why you should lie on your stomach and crawl if the ice beneath you cracks, or why you must not touch two wires with both hands when working with open wires.
We all live in a world governed by physical laws, and there is no way to bypass them. They can be studied, used, and, of course, they are impossible not to marvel at! So let's do it right now!
