It fits in you (man) purse, yet covers the equivalent of 2000+ pages in mainstream textbooks. Also, it covers both calculus and mechanics in an integrated manner (something not usually done). Finally, it's (arguably) fun to read.
RE price: I would price the book less, but Amazon discounts the book like mad, so if I want to keep any semblance of respectability (i.e. above $20) I have to price it at $39. I also setup a 40% discount on lulu for today to match/beat the amazon discount.
Yep. If you email me a proof of purchase (e.g. lulu receipt) I'll be happy to hook you up with the ebooks.
I really want people to read the print version---it is so much better than the PDF, because you can flip through it, refer back to previous sections, and most-importantly the small size (5.5" x 8.5") makes the book look un-intimidating.
It's a math textbook. There are thousands of them. What makes this one so special? The fact that it says, "No B.S."? It has a fancy webpage?
It looks pretty standard, and isn't even very cheap.
