Introduction
P hysics is what its all about. What whats all about? Everything. Physics is present in every action around you. And because physics is everywhere, it gets into some tricky places, which means it can be hard to follow. Studying physics can be even worse when youre reading some dense textbook thats hard to follow.
For most people who come into contact with physics, textbooks that land with 1,200-page whumps on desks are their only exposure to this amazingly rich and rewarding field. And what follows are weary struggles as the readers try to scale the awesome bulwarks of the massive tomes. Has no brave soul ever wanted to write a book on physics from the readers point of view? One soul is up to the task, and here I come with such a book.
About This Book
Physics I For Dummies, 2nd Edition, is all about physics from your point of view. Ive taught physics to many thousands of students at the university level, and from that experience, I know that most students share one common trait: confusion. As in, Im confused about what I did to deserve such torture.
