I flunked high school physics, but always thought that there are things very interesting in the subject. Years later, i stumbled upon this book from Dominic Cumming's list, eager to learn back everything i missed.
The book turned out perfect. I have yet to find such a great combination of efficient explanation and math (which are optional throughout the book). While some stuffs needed update (e.g. solar panels got cheaper in the last decade, a recent photo of a blackhole in the middle of the galaxy), the fundamentals are sufficient to explain everyday physical phenomena, and provided basic for current technology, so you would be prepared for coming ones.
While this is a textbook, it proved exciting enough to be read cover to cover (though i'd be coming back to reference stuff). The chapters on Atoms, Chain Reaction and Quantum Mechanics are particularly interesting. I've been looking for an equivalent of this book on different subjects (biology, for example) but have not yet to found one. Choose this book over the popular Physics/Energy for Future Presidents by the same author.
This book helped me to become more scientifically literate. It taught me not only physics, but a way of thinking.
