what this book does wonderfully well that is sorely lacking in almost all text books and lectures is to give you a good idea of how physicists think and how they approach physical problems ... not the dry mathematical techniques, but such things as modelling, handling big numbers, approximation, etc

it positively radiates a love of physics and real joy in looking at the world aound us

for an even more accessible introduction to physics, try Krauss' other book: 'the physics of star trek' ... phasors on stun ...
