Why do people write new text books?

[Cyrus]

I would much rather have the current libertarian approach to textbook selection than some Mother-may-I group that selects the reference text for some subject. I live in a bible-thumper state. The state school board is constantly under pressure to select texts that issue caveats regarding religion versus biology, geology, astronomy ...

Yet, this has nothing to do with what I am talking about.

Even though classical physics is 200 years old, the way it is expressed and the way in which it is taught are not. I cringe at the thought of having to express physical concepts without resorting to modern mathematical and physical notation. How in the world did they do physics without the concept of vectors?

What do you mean "modern"? This notation has been used almost since what, at least the 1800s?

By now, there should be at least one book that is generally accepted as "The book" on physics at different levels.

That's nice and idealistic, but not how the world of capitalism works. Book publishers want to make money just like everyone else does.

How would they lose money? They still have to sell x number of books to every student around the country. Who writes it makes no difference. A sold book is a sold book.

:rofl: I just remembered what Clausius said a while ago:

And I have to say also that maybe the book is wrong also (I cannot judge that because I didn't understand the business of the tarp), in part because nowadays there are so many awful books of general fluid mechanics in the market that even the trash guy has written one.

By now, there should be at least one book that is generally accepted as "The book" on physics at different levels.

Why? Out of all the possible content that can be included, there will always be varied opinions on what is sufficient. You can't put it ALL in, so people will differ in opinions on what should be left out or included or what depth is adequate.

How would they lose money? They still have to sell x number of books to every student around the country. Who writes it makes no difference. A sold book is a sold book.

You are aware there are far more than one textbook publishing company, right? And that the authors get royalties, right?

Cyrus, It is an interesting question. There's one problem, the union of procedures and ideas for certain topics are not that easy. For example, engineering considerations in design of structures of reinforced concrete in Latin America is different than in North America, plus they are different from country to country inside of them, too!. How in the world can one book have all the proper information? Maybe such topics are not that easy (even though the ideas behind the design in the core are the same or should be).

You mentioned basic sciences such as physics. It is interesting... In fact, classical physics require have a lot of depth!. How can one book be deep enough for the experienced learner and shallow enough for the novice?. At least that's the idea of going from intro physics (Resnick) to Classical Mechanics (Landau or Goldstein).

I may be wrong!, perhaps you meant the same book for each of those classes, rather than such an atrocious idea i just mentioned above. I don't know for introductory physics i had 3 books (Serway, Resnick and Young). I read each chapter how was presented on each book, and i believe i have a good enough understanding of what is going on.

Frankly, for many of the subjects I've taken at college, I've had more than one book (photocopies, library, my property or my dad's), except for Mechanics of Material. It has come to the point where i always consult as many books as i have on a certain topic. I like it this way. Well anyway, i got a midterm tomorrow on Labor Code applied to construction, and i need to wake up early to review, but i'll be back .

I'll sum it up: we live in a world of millions of choices, which are being bombarded onto us constantly from every side. Start in a supermarket, end up with textbooks.

But a sold book that the student can resell to one of next year's students makes them no money past the initial sale until the text is replaced. What really used to frost me was professors in lab courses changing books, so that your texts, lab books, study aids, etc were all worthless to the next class of students and you couldn't sell them privately. Trudge back to the book exchange and get maybe 10 cents on the dollar for all those expensive books IF they are in great condition. :grumpy:

 

[Jimmy Snyder]

the content of a good physics book is the same for nearly 200 years now.

One of the things that a working theoretical physicist does is find simpler approaches to problems that have already been solved using more difficult methods. For this reason, material which was once only taught to graduate students is now taught to undergraduates, etc. The content changes because the techniques improve.

 

[Jimmy Snyder]

I can have 'two' good books, for example on the same material. One might explain something one way, the other book a different approach.

In my case, I consult Dirac's "Principles of Quantum Mechanics" in order to understand the material, and Shankar's book of the same name for exercises.

 

[Thrice]

Or in my case I read a mathematical book on relativity because all the books in the course & most the physics library couldn't care less about rigor. I completely understand why they emphasize the physics & all, but I need more structure.

See there's no reason to stop at 2.

I don't know,

My last year of undergrad, I stopped buying textbooks, and would just pick up older versions or with the same subject at the library for free. Sometimes the text I used was from to 60's

No wonder the price is so high, since I don't know who would actually buy this book. :tongue:
