Sun Founders' Push For Open Source Education 169

theodp writes "Unfortunately for textbook publishers, Scott McNealy has some extra time on his hands since Oracle acquired Sun and put him out of a job. The Sun co-founder has turned his attention to the problem of math textbooks, the price of which keeps rising while the core information inside of them stays the same. 'Ten plus 10 has been 20 for a long time,' McNealy quips. 'We are spending $8 billion to $15 billion per year on textbooks' in the US, he adds. 'It seems to me we could put that all online for free.' McNealy's Curriki is an online hub for free textbooks and other course material. Others hoping to bring elements of the Open Source model to the school textbook world include Vinod Khosla (who co-founded Sun with McNealy), whose wife Neeru heads up the CK-12 Foundation, which has already developed nine of the core textbooks for high school."

      $8-15 billion wants to be free?

      Yes, but...

      Important distinction: You don't put stuff online for free, you make it free when you put it online. I work for a 'free' legal information service that spends hundreds of thousands of dollars a year being Free. People give us money because they understand that if ignorance of the law is no excuse, then free access to legal materials is kind of an important corollary.

      McNealy's right - there are tons of good reasons to make educational materials available online, free of charge. It will take a considerable investment to do so.

        This one's sat at the back of my mind ever since I read Feynmans account of reviewing math books.

        I mean for some things like history every country/area would want significantly different books to focus on local history etc but how is it that basic math books haven't been supplanted by a handful of public domain high quality books?
        of course I know the answer is that companies making thin margins printing public domain books don't have so much money to spend on guys in suits to go around and convince the people in charge to use their textbooks.

        I know how terrible some of the schoolbooks are yet they get chosen by schools year after year.

        • I always thought the colleges were accomplices as it was another source of revenue for them having an on-campus book store without raising tuition.

          Schools I'm not so sure, as they often have to answer to their state capital although I'm sure there are kickbacks there as well (like the annual chocolate selling scheme and/or gift catalog is one major kickback to the school).

      USSR science textbooks. Seriously, they are great (with some obvious exceptions :) ) and they are out of copyright.

      For example, Fichtenholz's "Differential and Integral Calculus" is THE best textbook on calculus ever created. It's so clear and written in so beautiful language that I had actually re-read it just for fun. I don't know if there are translations into English, alas.

      Landau and Lifshitz's "Course of Theoretical Physics" is the one of the best reference books for the modern physics, and it's available in English. It's out of copyright but its translations might be copyrighted.

      I'm certain it's possible to create a decent course on math/physics without much problem. Also, other countries should also have a lot of good material.

      It'd be different for the modern fast-moving fields of biology, chemistry, etc. But there's no reason for math/physics books to change every year (or even every decade).

        One of the most popular science books ever printed was Physics for Entertainment, http://www.archive.org/details/physicsforentert035428mbp [archive.org] by Yakov Perelman http://en.wikipedia.org/wiki/Yakov_Perelman [wikipedia.org]

        During the great days of the Soviet Union, the Russian Foreign Languages Printing House translated it into every major language, and sold copies at third-world prices. Those devious Communists -- promoting socialism by distributing cheap science books! Many scientists, engineers and mathematicians working today were inspired to go into their careers by this book.

        The most notable was Grigory Perelman (no relation) http://en.wikipedia.org/wiki/Grigory_Perelman [wikipedia.org] who solved the last step of the Poincaré conjecture and was eccentric even by Slashdot standards. Grigory's father gave him Physics for Entertainment.

        It used to sell for $3.99. Then it went out of print, and I tried to buy it, but it was going for $200. Now somebody reprinted it in a (probably) unauthorized edition, and it's also in the Internet Archive.

        The Soviet publishing house had an army of editors translating Russian books into all the world's languages, and they probably did Fichtenholz if it's that good.

        Dover Publications got started reprinting out-of-print and out-of-copyright science books, and as I recall, a lot of their trade list was Soviet books translated into English. At that time, the Soviet Union didn't believe in copyright, and they were happy to see their work reprinted. One thing the Soviets did well was science education. (http://en.wikipedia.org/wiki/Sergei_Brin)

        You might check out the old Dover catalog to see if there are any out-of-copyright English translations. Scan them and put them on the Internet.

    The reception to this effort will be especially positive after the Higher Education Opportunity Act [uwire.com] goes into effect (requiring a list of changes for a new edition of a textbook showing how it differs from the older edition). As it currently stands, the author could change a few equations, and add a couple graphs, and call it a new edition.

    The whole textbook business is one of the biggest scams in education, and it only gets worse in college. New editions are churned out for the college market simply to ensure a fresh revenue stream for all involved. I think in 95% of math, science, lit, and history courses, you could go to Dover Publishers (the people that basically make their living reprinting stuff in the public domain), get the books in paperback, and actually get better textbooks in the end. I have a weird hobby of collecting pre-1950 textbooks, and frankly I think kids learned "more" back then from their textbooks than they do today. Obviously, some knowledge has been added here and there, but I've got an 8th grade science textbook that does a much better job imparting the principles of physics and chemistry to kids because of the practical examples used.

I'm sorry, but the technology to make books has actually decreased in cost, yet the cost for the actual product has tripled, in just over a decade?

      In my opinion, the NY Times article focuses mostly on aspects of the free textbook movement that have been the least successful. It focuses on K-12, but actually there are very few high-quality, free K-12 textbooks; most of the high-quality, free texts are at the college level, and especially at the graduate level. This is probably partly because the opportunities for profit in a non-free book get thinner and thinner as you go to higher and higher levels, and also partly because most states' public K-12 sy

  • To be fair, I've heard stuff about open-source textbooks for a while. This isn't really a "Scott McNealy and his friends" idea, more of a "Scott McNeally showed up to put some weight behind his version of an idea that other people have already been working hard to do."

    I also thought that the 10 + 10 = 20 example was a bit simplistic, since textbooks get updated frequently. Although, to be fair, if people can create open-source textbooks, it's a benef

      Trying to ignore x86 is generally what DOOMED Sun and allowed for the rise of Free Unix.

      They tried to fight the future and it ran them over like a freight train.

      To me, it seems Sun's problem was that they didn't really 'get' how to foster a FOSS project and build a community (it takes more than just hiring Ian Murdock). Sun had other problems, but being smarter and more proactive about FOSS could have helped, although I'm not sure how much of an impact it would have had.

        Linux was announced to the world in 1991 with the following announcement:
        I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones.

        SunOS started in 1982, that means they had 9+ years to get their OS into the hands of kids using x86. They failed and it killed them. They might not have seen it coming, no one really did, but it still did them in.

          Heck, solaris started in 1992 had they made it FREE software to begin with it would have prevented linux killing them.

  • Will they just drop support for an old edition of a book on a whim a la Sun? Or will they do the right thing and not follow in the publishers' footsteps?

  • Perhaps McNearly should lobby for a decent textbook on how to use apostrophes.

    • "Push" is a noun in the headline. That is, it is about a push, by the Sun founders, for open source education.

      Also, the editor usually writes the headline, not the submitter.

      If you're going to post flamebait, at least try to be correct.

    • I see McNealy and Khosla mentioned. That would be founders, and their push for Open Source Education is described.

        • Scott McNealy has some extra time on his hands since Oracle acquired Sun and put him out of a job.

          Others hoping to bring elements of the Open Source model to the school textbook world include Vinod Khosla (who co-founded Sun with McNealy)

          It's amazing what basic reading skills can do. If textbooks weren't so expensive, perhaps your school could have given you those skills or at least the ability to use your browser's built in search feature to search for 'McNealy' and 'Khosla'

    When it comes to college level stuff, mathematics has more free books available online than any other discipline.

    Yet, most universities use either James Stewart or one other book for calculus.

    Why? I really don't know. I asked a math grad student friend of mine, and he said it ultimately boiled down to politics: Calculus level textbooks are decided by a committee, and the professor teaching it only has some say - and it's hard to convince a committee. As hundreds of students will take calculus every semester, they need the warm and fuzzy feeling an established textbook gives them.

    To be fair, the mathematics departments are also perhaps the most likely to use free/cheap textbooks (compared to sciences and engineering). This usually happens for upper division courses, though.

    • However Stewart is a great calc book. Got mine second hand for about $10NZD and will never let it go. We were told that any edition will do.

    The Education Department (ED) issues a Recommended Textbook List. If the publishers want to be on that list, they have to reduce the unnecessary revisions. That seems to work extremely well:

    >According to the Consumer Council's surveys, unnecessary textbook revisions have been greatly reduced in recent years, dropping from 21% in 1992 (six out of 28 textbooks) to 2% in 1996 (one out of 44 textbooks). From a random selection of revised textbooks in 1997, no unnecessary revision was detected (out of the eight sets of books examined, revisions to two were found necessary and those to the remaining six quite necessary).

  • The headline of the article has a totally random trailing apostrophe after "founders". Why?
  • It should be pointed out that at least for the HS high school market, the math content of the textbook is only one aspect upon which sales are based.

    Most importantly, in most states and provinces, there is an approval process for textbooks that measures dozens if not hundreds of parameters including binding quality, use of names in examples (should reflect diverse population), male/female ratios in illustrations, avoidance of culturally specific contexts in problems, etc.

    It can easily cost tens, if not over

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
