...is the textbooks. Especially Math textbooks. There are only a few(like, 1%) textbooks that actually get to the point. There's so much useless information in these textbooks that you'd think the author included them in their just so that his/her textbook can have x amount of pages to be respectable to other textbooks.
I'm looking through my Calc 3 text book and it's over 1100 pages long not including index and prefaces and such. I'm thinking...WTH would I need 1100 pages of math in one semester? The book weighs like a large baby and it has so much filler that it's ridiculous. Like the vectors chapter, it shows that i+k = i+(-k) and then proceeds to do an entire example of 6 vectors such as 3i+5k = 3i + (-5k - 3i) + (3i + 10k). I'm like...what the f***?!! That's like trying to show the many ways of getting the number 2. 1+1 = 2, but so does 5-3, and 150-148. It's implied already you moron...no need to show COLLEGE STUDENTS how it's done. Jeezus christ.
Not only that, most of the examples are only valid for the "easy" problems at the end of the chapter. The author goes on to lengthy descriptions that are just absolute filler. He makes the simplest calc problems look like rocket science because of all his stupid explanations that are clearly filler.
Not only that, authors have these stupid "editions." I've read many editions of the same book and I must say...there is little difference between them. Even the problems are the same. And the author talks about how he added all these additions...and I'm wondering "Oh, I didn't know that adding a thank you to your wife warranted another edition...making my current book useless to sell at the book store." Ass.
Oh well...I'm sure you folks have other things you hate about college.
