I am talking about upper and lower division textbook in mathematics and physics. Why are they in geneal so hard to understand, and so low quality anyways? This is not just an attitude for the intellectually inferior, but something i repeat heard from my own professors in mathematics, and physics. It seems for most students, most of the understanding of the material comes from attending the lectures, and taking the notes. A follow up question would then be: Why are the notes are so much better than the books, but yet we have so much more books, and hardly any notes in our libraries? i asked this question before, but i dont think it was the right forum. since only professors write textbooks. I would like to ask the professors out there: Why don t you just give us the notes? Is it too much to ask? Why is it the most of your don t like the textbooks, and do nothing about it?
