Free MIT Engineering Text For Download
An anonymous reader writes " The (sci-tech) Library Question is reporting, "The third edition of A Heat Transfer Textbook, written by John H Lienhard V (MIT) and John H Lienhard IV (U Houston), has been made available on the web. The book is an introduction to heat transfer, geared towards engineering students. It may be downloaded free of charge. The authors explain:
We are placing a mechanical engineering textbook into an electronic format for worldwide, no-charge distribution. The aim of this effort is to explore the possibilities of placing textbooks online -- effectively giving them away. Two potential benefits should accrue from doing this. First, in electronic format, textbooks can be continually corrected and updated, without the delays inherent in printed books (second and later editions are typically published on a five-year cycle). Second, free textbooks hold the potential for fundamentally altering the economics of higher education, particularly in those environments where money is scarce."
This is a very good idea; it would be nice not to have to pay $500+ a semester for books. I am concerned that if this catches on, that a company would find a way to profit from the online books, bringing the college students back into the same situation that they're currently in, which is paying out the ass for basicly renting books for a semester (assuming the college has a book buy back program).
Another thing, will schools then start supplying laptops or tablet PC's to view these text books on while in class?

With some engineering and science -related courses suffering from low levels of interest, a wider availability of resources could (as the article suggests) draw out those who aren't applying for financial reasons, whilst giving others a taste of subjects and their potential uses in picking a career path and making a difference. After all, most people have felt they've had a good idea or two at some time or other... many have been discouraged only by the lack of readily available background knowledge.
Yay for more open learning!

Also, one of the big issues in textbook publication is that the information included sometimes can be determined by what state publishes the text - this is especially true in history and biology, both of which are full of political dynamite.
Maybe eventually this will lead to a freer exchange of information.
While not having to carry around textbooks is nice, and I'm never without a Palm or laptop, I have to admit I always prefer reading printed text. Maybe I'm old fashioned, but I just find printed text I can write on, fold, flip through, read in the sun, etc. to be a lot easier to read from.

Altering time, one time at a time.
I've heard people talk of these ridiculously high costs for books in the US before. in my experience it isn't true here in the UK: to me an expensive book is above 30, and a book above 40 has no chance. also I've bought ~6 books over my 4 year degree, mostly because I wanted to, you are never required to buy a book.
in my courses (physics) the point of lectures is to obtain a set of notes good enough to work completely on their own in most cases. questions and answers are also provided by lecturers.
without wanting to sound like a flame or anything, is it possible that in the US lecturers just can't be bothered or aren't given the resources to teach their pupils properly and so fall back on textbooks which the money-grabbing publishers are happy to exploit (I've heard tales of unnecessary book-CD bundles etc. all just to inflate prices).

It was our idea that we should start with an introductory physics text, say, basic mechanics. The ultimate product would be an .iso disk image which contains not only a textbook, but recordings of key lectures, some highly compressed video and simulations of certain experiments, perhaps rendered in a GPL 3D graphics engine (where physical principles would be programmed in, and students could manipulate the setup and observe realistic changes in the results).
This would be a large and publicised project, and one that could/should attract enough NSF funding to cover its modest costs. (I've seen the NSF give money to much more frivolous ideas!) The initial text might be a "donation" from a cooperating professor, and the audio/video lecture fragments would also be solicited recorded in the classrooms of truly excellent faculty. (Nobody I talked to about this said he/she would refuse.) The various programs and simulations that need to be written would come from contracted, qualified and paid programmers and graduate students. (And perhaps volunteers.) All their code would be GPL.
Once the project gets going, a working group, organized much like an editorial board, would solicit and review new submissions and alterations. There can be arbitrarily many exercise problems, as well as detailed explanations of their solutions.
These would fully take advantage of the digital format. One weakness of paper textbooks is that by their nature, they have space for only a few fully-solved and explained sample exercises. This would not be a limitation of an electronic text. In fact, how to solve an exercise could be explained in several different ways by different instructors, maximizing the chance the student would "get it". I imagine an interface where next to each step, there is a small "how does this follow?" button. If pressed, it opens a small window describing the motivation of a certain transition.
Many of these details and elaborations could be contributed by users of the textbook. Like any major software project, there would be a moderated online forum to discuss issues related to the textbook. Ultimate decisions about how the text should be updated (the regular "distributions" of the GPL material) would be made by the editorial board. In academia many professors participate in editing journals pro bono, and we could expect something similar here. Feedback on the various aspects of the text would be solicited directly from students and instructors, and the editorial board would post "requests for updates" with specific issues that need to be addressed to make the project a better learning tool.
Well, we thought about many more details of implementation, but they are boring and you guys might have better ideas anyway. The point of the whole project would be primarily to have a supplement to introductory college-level classes, but the uses go far beyond that. The textbook would be designed to be self-learner friendly, something a motivated high-school student could easily work through. It could be duplicated cheaply and en masse (at first it would be a set of CD-ROMS, eventually transitioning to DVD-ROMS). In places where poverty, georgaphy and cultural factors limit access to higher education (which includes parts of the USA), people will still have simple computers and can cover the $2 for a burned DVD-ROM.
Of course, the idea would be to get one "hit" textbook and then reuse the software and other infrastructure to make more. Not only would this textbook require sequels, but also a demand for a calculus textbook in the same format. These are ideal fields for getting the project rolling, because introductory math, physics and chemistry textbooks don't get obsolete very quickly. How this project would be paid for re
The software we developed (I was the programmer on the project) was used for several classes on campus at Utah State University, where the project was based from, under the direction of Dr. R. Kent Wood (he has since retired). Our primary emphasis was more toward K-12 learning, but it proved to be quite popular with several computer-based learning groups including C.A.L.I.C.O, a group of individuals working on acquiring forign language skills through computer-based learning.
There are several issues that need to be dealt with in regards to multimedia development. Some of them have been solved compared to what I was dealing with in the past, but some still are huge problems:
