My advisor contrasted computer scientists, who he said *want* you to understand.<br />But you should read Visual Complex Analysis for a brilliant text book that avoids all that.

I don't really understand how publishers decide what textbooks to publish, but quality of exposition doesn't seem to be a major factor. <br /><br />I suspect a big part of the problem is that many textbooks are just polished-up lecture notes, and a lot of people write minimal lecture notes that contain all the technical details but leave the intuition and analogies out, either because it's so obvious to them that they don't need any notes to give the necessary explanations in class, or (almost the same) because they prefer to do all that stuff extemporaneously. <br /><br />In fact, some of the better textbooks I've read have been compiled from *students'* notes of what was actually said in class (rather than professors' notes of what they intend to say in class), which seems like it might be a better model.<br /><br />One trick that I've found helpful on occasion (especially when learning a subject about which there are no textbooks or at least no good textbooks) is to look up masters' or PhD theses on a topic and read the first chapter. The writers aren't necessarily any better, but because they're less comfortable with the material they tend to at least include more of it.<br /><br />In any case, I don't really disagree; I was mostly just objecting to the generality of your statement.shonkhttps://www.blogger.com/profile/17369367271546487712noreply@blogger.comtag:blogger.com,1999:blog-7225373.post-73555191585204755062015-07-06T20:34:33.750-04:002015-07-06T20:34:33.750-04:00shonk, perhaps the issue is what explanations work...shonk, perhaps the issue is what explanations work for what people. I am not bad at math -- I scored 800 on the math GRE, and that after heading straight to the 8 AM test after spending all night at a bar -- but I find the explanations of many mathematicians frustratingly sparse. I get math when I see the *structure* involved in the mathematics I am trying to learn. But many explanations seem to focus entirely on the formal notation: that is almost meaningless to me until I see the underlying picture of what is going on.<br /><br />And as Matt notes, I am talking mostly about books.gcallahhttps://www.blogger.com/profile/10065877215969589482noreply@blogger.comtag:blogger.com,1999:blog-7225373.post-68195870823063580802015-07-06T16:56:49.520-04:002015-07-06T16:56:49.520-04:00That has been my experience in a classroom setting...That has been my experience in a classroom setting, shonk. But it has also been my experience that when teaching oneself advanced mathematics, the only resources available are books of terse explanations and proofs.<br /><br />A mathematician (disclaimer: I'm not much of one) might argue that one better learns how to do math themselves by carefully thinking through the proofs and working through the exercises on their own rather than being spoon-fed.Matthttps://www.blogger.com/profile/02470489293820651609noreply@blogger.comtag:blogger.com,1999:blog-7225373.post-5293339133714137322015-07-06T00:11:59.895-04:002015-07-06T00:11:59.895-04:00Pretty sure you're just hanging out with the w...Pretty sure you're just hanging out with the wrong mathematicians. There are many mathematicians who are also excellent teachers, and all of the ones that I've encountered are well aware of this particular distinction between what's appropriate when explaining mathematics versus when doing mathematics.shonkhttps://www.blogger.com/profile/17369367271546487712noreply@blogger.com
