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 great initiative. It promotes the idea that we should look at the real value in education. The real value is in the people students get to work with (eg. the authors), and the personal experiences they go through on the way to graduate. Why should publishers make profits in this process when they don't add value?

      Of course, it could also be asked why should the authors participate in this process if they don't make any profits?

      Writing a textbook is not an easy feat, and posting them online for free download doesn't give the author any sort of compensation for their work other than the satisfaction of making students happy.

      Also, I find it unlikely that this will really catch on, simply because most of the professors I've dealt with simply would not consider a textbook like this, or wouldn't even be aware of it. The publishing industry does market itself really well - professors get sample books which often end up being used for classes. A prof might see an online book as being somehow of lesser caliber (in terms of factual accuracy, author credentials, or otherwise) than an actual printed book.

      I would imagine there would also be legal liability issues involved in this, suh as if the text accidentally contained false information.

      It's a good idea, but I don't think it's the way to go. Low-cost textbook distribution needs to happen, but I don't think no-cost will work -- at least not yet.

      It is a well known fact that the authors don't get much (financially) for publishing a textbook. On the other hand I wouldn't go as far as saying that publishers don't add any value, but I'd say that the value they add is not proportional to the final price.

      The trouble, of course, is that with (especially graduate) textbooks, there are very few people who'd possibly buy it, making publishing them an expensive task.

      Why does someone write a textbook?
      Well its certainly not for the money. The typical textbook brings in negligable sums at best. Typically about 2000 GBP as far as I can tell. The general reason is because you require a book for your students that doesn't exist. And if you have the course notes you've written to hand then its more or less there as a by-product. A bit of polishing and you are away.

      Sorry, I know this sounds a little disappointing, its done for reasons of dull expediency and neither fame nor fortune.

      For graduate level texts/"professional" publications the story is of course rather different, and the reasons for doing it are pretty much the same as writing journal papers; (i) "publish or perish"; (ii) mindshare within your field; (iii) again, the damn book you wish was written for your students (this time grads) doesn't yet exist. Writing a whole book is a little inefficient insofar as its only one line on the CV and indeed, if we look back before the days of "publish or perish" you will note that practically everyone had written a book at some point in their careers. However, this seems to be a declining trend, at least within the sciences where time is perhaps better spent on publishing normal papers or writing grant applications.

  12. errors in textbooks, PC by kardar · · Score: 3, Insightful

    I still have on one of my hard drives somewhere a PDF file that points out really horrible errors in typical school textbooks; these were mostly high-school books, but in any case, it really points to the pressures that are placed on book publishers; many pressures that have nothing to do with accuracy of information, but coming from a sense of policital correctedness, and so on. There are influential people in the management levels of the textbook publishers, and there are certain standards that must be upheld in order for that book to be selected by a school system, especially a school system that is funded with taxpayer dollars. Obviously, having checks and balances when it comes to taxpayer dollars is an important thing. But the errors are pretty bad, and there are quite a few of them, at least in the one review there that I read.

    Perhaps the idea of putting this kind of information online, if there is a way that this can be done without too much lost inertia from the fact that you are just giving away your hard work for nothing (i.e. also sell the book in hard-copy), have a donation place for it, or somehow organize funding in some other way. Also, you don't necessarily go through a big publisher to do it this way - you can have more freedom to simply produce an accurate textbook, without having some committee breathing down your neck or having your work thrown in haphazardly with ten other authors' work.

    And there may be more control over the authorship, and the way the whole thing is put together.

    But generally speaking, for instance, O'Reilly books are not that particularly expensive, and I just kind of feel better contributing some type of financial money to the author, and having a hard-copy book has its benefits as well, in case you feel like not being tied down to the computer or laptop screen. I like buying books, but I also like using electronic formats sometimes (it's easier and faster to take notes), it's especially cool when you are studying a programming language and you can see examples in the book and try out your own while you are physically sitting at your computer.

    Electronic formats are good, and hard-copies are good too. What really needs to happen is that the cost of the textbooks, the hardcopy textbooks, need to come down by at least 50%. Again, this can be blamed on the "big publishing companies" - many of the policies and procedures that are commonplace at these types of embedded publishers drive the costs of textbooks up, and increase the number of errors in those textbooks at the same time. Paying some 30 dollars for a very excellent O'Reilly book, for instance, is really no big deal, considering how long it's going to take to read it and work through it, and hopefully the authors are getting some kind of reward in there too. Having an electronic format available for free, especially in the situation where one has purchased the hardcopy, is, I think, a really good idea; especially if that electronic format can have an errata somewhere or something.

    To sum up, I think that the price of textbooks needs to come down, and the errors need to be lesser in number as well. These two things appear to be tied in together, to some extent. Furthermore, there should be a means to reward the authors for their work; I don't think that giving away books for free is really going to encourage people to write quality material; there needs to be some sort of way to integrate the hard copy and the electronic copy in a way that increases the benefits to the reader and still rewards the author and encourages more people to write quality material.

    I think that this is going to turn out to not be quite as easy as it sounds.

    Second, because the free electronic books are subject to frequent revision, other experts and students can submit criticisms and suggestions that can be instantly incorporated.

    I teach at a large university and my colleagues and I have spend some thought on open-source multimedia textbooks - not PDFs, which are almost completely inferior to their paper counterparts, and take no advantage of being consumed through a computer.

    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:
    • Multimedia standards - This is one of the areas that due to the emergence of the World Wide Web and other generally open applications has pushed this forward quite a bit. MPEG, PNG (MNG), and other standardized formats have really made a difference over the zoo of incompatable formats that there were even 10 years ago. There is still need to do more work in this area, and there are some items that really need review. Multimedia game design and the entertainment industry, unfortunately, are the major drivers of this sort of activity.
    • Accessable Multimedia Materials - Due to the "eternal" copyright of many multimedia types (photos, audio clips, cinema in all its flavors) are copyrighted and impossible to use as "fair-use" for educational purposes except on a very limited basis. Court ruling on this strongly favor the media companies and make it almost impossible to use anything that is available. The Google image search is essentially worthless if you want to use it in any instructional software that would be used for more than a single section of a single course taught at only one university. I would love to see a Multi-media variant of Project Gutenberg where you could get central repository of multimedia items (a clip art library, music clips, video, etc.) that would be guarenteed to be totally public domain or released in some copyleft arrangement. There is quite a bit on the internet, but it is scattered around and really needs to be put together. There are some collections (I happen to have some content I'd like to donate) that simply needs to be put together, scanned, and released. If I had infinite resources and time I'd like to do this, and if it isn't going by the time I get close to retirement, I may get this going myself anyway. I just need to feed my family for now.
    • Authoring System Support - There needs to be a standardizing the "glue" format that holds all of this multimedia information together with Unicode-based text that is appropriate in a computer-based learning environment needs to be worked out. HTML and its variants are pretty good, and there some fairly decent "authoring" tools available such as Authorware or Director, but these all have some hard limitations. The High Schools that I've seen are typically either using HTML or Power Point (I am not kidding here either) for routine stuff that is developed. University-level instruction is totally non-standard and often includes custom software written for the one project, which eats up almost all the time and resources of the project. Ideally I'd love to see an open-source project that would help put this sort of instruction together. It needs to be easy to use, but powerful enough that if you are willing to learn (with a shallow learning curve) you can get progressively more features to the point that you can write the entire authoring environment in itself (aka be Turing complete). Nothing I know of has this capability at th
