Griffiths, he's great. If you've read and understood undergrad mechanics, e&amp;m (Griffiths), and quantum mechanics (Griffiths), then you're ready for this book and you'll know what to expect from Griffiths.<br><br>I like his wordy introduction  to the subject---he tells the history of particle mechanics like a story, thus making it easier to memorize the particle's names and properties. I'm using this book as a backup to Perkins. Perkins flies through this stuff, Griffiths actually explains it.<br><br>The font size in this paper back print is kinda small, maybe 10 (pt).<br><br>Some of the information in this book is dated given the youth of the subject. Nonetheless, I'm finding it to be a good introductory text.
