Martin Posted October 1, 2007 Share Posted October 1, 2007 We've reached the target date and there is no way short of divine intervention or a computer error that their prediction will not turn out right. I just checked Amazon.com and going by salesranks the Smolin book was selling over 9 times better than the five most popular string books average. Checking at noon pacific time will make it "official" but i don't see how the picture can change substantially in the next three hours. *The Trouble with Physics...and What Comes Next* rank was #637 among all books, and the top five stringies were fabric 4021 elegant 4542 endless 6633 warped 6710 parallel 7140 so the average stringy rank was #5809.2 and the ratio 5809.2/637 was 9.1 For their prediction to be the closest, it just has to stay up over 4.5 for the next three hours. This is pretty remarkable. I was expecting something around 2 or 3. We had seven people's predictions and four of us predicted in the range 1-3. Congratulations to Yourdadonapogostick, Phil, and Bascule! You are either incredibly lucky or you have a way better sense than I do of how the reading public is thinking.

PhDP Posted October 1, 2007 Share Posted October 1, 2007 Survival of the luckiest To be fair, it was more wishful thinking than a real prediction. I'm not a physicist, but I read about string theory I tend to side with skeptics. Link to comment Share on other sites More sharing options...
Martin Posted October 1, 2007 Author Share Posted October 1, 2007 The final outcome came surprisingly close to your prediction! 1 October noon pacific Smolin book's rank #797 average rank of five most popular string #5165.6 ratio = 5165.6/797 = 6.5 in case anyone's curious the currently most popular stringies were fabric 3203 elegant 4163 endless 5420 hyperspace 5494 warped 7548 You guys said 6 and the actual outcome was 6.5.

bascule Posted October 3, 2007 Share Posted October 3, 2007 Why don't you include the numbers from ``The Secret'' to improve your averages? I know you're trying to single Martin out for an argument from popularity, but seriously... you're comparing the Trouble with Physics to The Secret? You may as well compare Steven Weinberg to Deepak Chopra </slippery slope> Martin's guess the X ratio polls are all in good fun and shouldn't be interpreted too seriously. I think if there's something to be taken from them it's that string theory research/interest is waning in light of certain intractable problems, many of which are enumerated by Smolin in his book, but I don't want to speak for Martin... -- On an unrelated note, wonder what caused the spike in interest regarding TwP... A potential hypothesis: The book's original publication date was September 19, 2006, and it may be drawing some additional attention due to its one year anniversary (which may even be a delayed effect as more readers become interested after reading blogs et al about the one year anniversary) Link to comment Share on other sites More sharing options...
BenTheMan Posted October 3, 2007 Share Posted October 3, 2007 you're comparing the Trouble with Physics to The Secret? Pseudoscience is in this year. But seriously... The point is to show how ridiculous this all is. You may think that this is ``great fun'', but it seems that martin takes it awfully serious---to the point of spending his time scouring amazon.com sales records. Showing that Lee Smolin's book is selling better than some string books is kind of a goofy thing to do. Personally, I am more impressed that Elegant Universe is the top selling string book after almost ten years in press. Link to comment Share on other sites More sharing options...
Martin Posted October 3, 2007 Author Share Posted October 3, 2007 ...--to the point of spending his time scouring amazon.com sales records.... don't worry, it just takes a minute or two to do. currently the ratio is 9.6 "Trouble..." salesrank is #638 average of topfive stringy ranks is #6113.8 Just relax and don't worry so much. No harm in keeping track of a few numbers. It can serve as a reality check for anyone who finds them surprising. ===== BTW just as an afterthought, why not join the citations poll? http://www.scienceforums.net/forum/showthread.php?t=28255 If you only want to focus on stuff you think is really serious---the drop in citations of recent papers should be of concern. I'd be interested to know your views. I recall the science reporter for the Sunday Times of London commenting on the sharp drop in string citations in a BBC interview not too long ago. Compared to citations, booksales are a fairly trivial matter. They don't prove a book is right or wrong of course and nobody suggested they did---they do give some idea of impact however. If Brian Greene "Elegant" hadn't sold like it did then it would not have had such an impact. Link to comment Share on other sites More sharing options...
BenTheMan Posted October 4, 2007 Share Posted October 4, 2007 If you only want to focus on stuff you think is really serious---the drop in citations of recent papers should be of concern. It's only a concern to people with nothing else to concern themselves about. Besides, it's all a bunch of bullshit like these sales numbers---they don't MEAN anything, except to people like you and Peter Woit. Look at how many people cite Maldacena's AdS/CFT paper. Or Witten's String Theory Dynamics in Various dimensions. These papers outlined HUGE new areas of research, neither of which could be filled out in five years.

Martin Posted October 4, 2007 Author Share Posted October 4, 2007 Ben if you really think that, then you haven't been in academia long enough. If you ever get to the point of applying for a postdoctoral fellowship, or for a junior faculty position, you will realize that citations are the lifeblood. The quality of your research, once it passes peer review, is gauged by how many people read it and consider it useful enough to cite as reference in their own papers. Of course subjective judgment, by senior people, is important too. And the two kinds of measures often agree very closely. The highly respected (on subjective grounds) is often the same as the highly cited. Just how it works out. I suspect you actually know this, so when you deny that cites matter it is just defensive bluster. If that is the case, then bluster away I don't think it does any harm.

Reaper Posted October 4, 2007 Share Posted October 4, 2007 don't worry, it just takes a minute or two to do. currently the ratio is 9.6 That's pretty high, especially given that the other theories are much more obscure in the public realm.

Martin Posted October 4, 2007 Author Share Posted October 4, 2007 At least not any more than taking pot shots at string theory Now there's a completely innocent activity if there ever was one! It has been so overhyped it will take years to deflate to reasonable size. BTW when Woit's book first appeared Edward Witten put out an urgent message to the string community saying "Don't respond! Whatever you do don't start counterattacking and acting defensive!" If I remember it was in a letter to Nature magazine. Or some other periodical--I seem to remember British but it could have been one in the US like Science. But then there was a huge fuss at KITP, which got out video online. And Joe Polchinski made a kind of counterstand. Leonard Susskind said some really snide things about Smolin. The debate took off---the Smithsonian Museum in DC sponsored a debate between Brian Greene and Larry Krauss ("String, a theory of anything? a theory of nothing?") My feeling is the string community personal interest would have been better served if folks had followed Witten's advice and not reacted at all. Just stayed cool, said nothing, and went about business. Link to comment Share on other sites More sharing options...

If that is the case, then bluster away I don't think it does any harm. Whatever man. I am not under the impression that citations don't matter. And if you really want my honest opinion, there hasn't been a field changing paper in the past ten years or so. The one paper that has come out recently that will probably spawn a huge cite count is Intrilligator, Seiberg and some other guy whose name begins with S, about metastable supersymmetric vacua. There are a thousand reasons why your index doesn't prove anything---perhaps the biggest reason is that the community is bigger now. Why don't you apply the same index to condensed matter, or biophysics? Or even (gasp) non-stringy quantum gravity approaches. Link to comment Share on other sites More sharing options...

Martin Posted October 4, 2007 Author Share Posted October 4, 2007 Personally I'd love to see citations in LQG compared to string theory I expect they would look puny in terms of magnitude. Most nonstring approaches date from around 1998* and for the first few years got very little support (still almost none in US) so it is a smaller community, which even though they are productive means fewer papers and so fewer citations. It's a GROWING community, though. I'll think about it. *vintage 1990s LQG got an earlier start. Link to comment Share on other sites More sharing options...

Martin Posted October 5, 2007 Author Share Posted October 5, 2007 Personally I'd love to see citations in LQG compared to string theory I'll do it! It won't be "compared to string theory" because I don't have comparably complete data for nonstring---and I'm not sure i am all that interested in a competitive format. But I will try to do some collective measure of QUALITY that we can track year by year to see if there are TRENDS. I am not sure what the format will be yet =========================== we have to work with the data that is available and it is not as complete but here is one way: for each year, like 2004, we take the top five QG and add up the cites they NOW have (in this case we arent lucky enough to know how many they got in that year) and then we divide by the number of years they have been accumulating cites, which in the case of papers published in 2004 would be THREE. This will give a quality index for that year. OK I am starting with nonstring QG published 2003 114 Spin foam models for quantum gravity. Alejandro Perez (Penn State U. & Schrodinger Inst., Vienna) .

Much of the first year often doesnt count because people have not had time to assimilate and write their own paper using the idea or facts that they will cite. So the main accumulation is in effectively four years 2004, 2005, 2006, 2007. So the annual RATE these papers accumulated cites was 86.8/4 = 21.7. This will be our measure of quality. Now let's see what the quality was of the papers that were published the NEXT year, in 2004. 259 Background independent quantum gravity: A Status report.

The quality of the 2004 crop was BETTER than that of the 2003 crop. the average 2004 paper (in the top five) accumulated cites at the higher rate of 34.3 cites per year during its lifetime so far.
