Sociology of Physics: comment and indices

In summary, the theoretical physics speaker discusses how intellectual fashions such as string theory function as expert fads. He does this in an entertaining and illuminating manner, with a lot of hand-drawn cartoons. Although Zapata got his PhD in string theory, I am apprehensively curious about what his postdoc job prospects are, given the nature of his comments.

To keep track of the drop in string citations in the professional literature:
marcus said:
...String citation standing in the Spires top 50 HEP has dropped. In the early 2000s it would often be that around twelve out of the top fifty would be recent string. And the rankings of those twelve were often near the top of the 50 list. By recent, I mean papers that appeared in the past five years, counting back from the year in question. For the year 2008, it would be 2004-2008.

In 2008 four of the fifty top-cited HEP papers were recent string. And the four recent string papers that made the top 50 list had average citecount of just under 180, which put them down near the bottom of the list. Their ranks were 37, 44, 48, 49.

In 2009 only one of the top-cited HEP fifty, was a recent string paper. And it was number 33, two thirds of the way down the list. The paper in question was cited 222 times.

Details were given in this post:

Here's the link to Spires topcites listings:
http://www.slac.stanford.edu/spires/topcites/2009/annual.shtml
...

The key thing here is how much recent papers were cited during the year in question. This is indicative of the current state of the research program. If one does not restrict to current year citations and to recent (past five years) papers then one gets huge numbers of citations reflecting the string glory years of the 1990s when the program was viewed as the most promising path to unifying physics (if not the only path :biggrin:)
==================

I'm looking for signs that we will see some correlation between the decline of professional interest in stringy unification prospects and a trend in popular book salesranks. For several past months, I've averaged the noon salesranks of the top five string books (whichever were the most popular on a given day) for three days around the 15th of the month.

Mid-month salesrank averages for the string top five:

January2007 4396
February2007 3789
November2008 3711
July2009 6485
March2010 7521
April2010 11983
May2010 6884

Out of curiosity I also recorded these recent noon topfive averages:

17 May 9479.6
18 May 8000.4
19 May 6982.0
20 May 8270.6
21 May 7030.2

It would make sense for there to be some slow upward trend: as professionals loose interest in string (as a unification approach) one might expect, after some lag time, for general readership to slack off. This would be reflected in rising salesrank numbers for string books.

Not trying at all to throw doubt upon any on the comparisons to date, and I doubt it will make a significant difference to the numbers, but I wonder if a harmonic mean wouldn't be a more meaningful average than the arithmetic mean. After all, the direct metric of popularity is number of books sold, and sales rank varies inversely with this metric.

Of course, it would only hurt to switch methodology mid-stream, so I'm not suggesting you change (or even consider changing) things for this thread...but it might be worth thinking about for any future cataloging from scratch.

Thanks for the comment Gokul! Your suggestion of a while back (averaging data around the first of the month, for a smoothed first of month figure) was one I adopted and I think has been helpful.

As you say, just keeping on consistently is the main thing, but I will consider harmonic means "averaging" if I start another thread recording a different series of data.

Hope things are going well.

String publication for the first four months of this year should have stabilized by now, as late arrivals were entered into the data base. First here is the picture for the first three months of successive years:

This does a search at Harvard abstracts (keywords: superstring, M-theory, brane, AdS/CFT, compactification, heterotic) for the first quarter of consecutive years.

As of 25 May, the Jan+Feb+March figures for four successive years were:
1670, 1643, 1583, 1307

On the popular physics book market (Amazon salesranks):
Noon 24 May string topfive average 8179.4 (fabric, parallel, elegant, hyperspace, little).
Noon 25 May string topfive average 8467.2 (elegant, parallel, fabric, hyperspace, little).
To illustrate, the average was obtained from their respective ranks which happened to be 4634, 5373, 6904, 11978, 13447.

=======Here are the raw numbers of LQG papers in successive years.
Loop research publication index uses the Spires base with DESY keywords "spin, foam", "field theory, group", "quantum gravity, loop space", and "quantum cosmology, loop space". Figures for 2005-2009 seem nearly stable.

Incidentally Trouble with Physics salesrank happened to be 14398. I haven't been checking reguarly but it still seems to be hanging in there.

Going back to 2007 and 2008, there does seem to be a slow upward trend in the topfive stringies average salesrank. It would make sense: as professionals loose interest in string (as a unification approach) one might expect, after some lag time, for general readership to slack off. This would be reflected in rising salesrank numbers for string books.

This week Brian Greene hosts the NYC festival of science which he organizes annually, much media hoopla including a visit from Stephen Hawking. Noticeable increase in sales of Greene books.

To keep track of the popular physics book market (Amazon salesranks) I show here some mid-month salesrank averages for the string top five. I plan to take noon readings on the 14, 15, 16 of June, extending this record.

As a spot check, at noon on 9 June the string topfive average rank was 9113.2. The five most popular string books at that time (elegant, fabric, hyperspace, parallel, little) ranked 2714, 5092, 5693, 6253, 25814.

June2010 9731
July2010 ...?...

Next readings, to extend this record, planned for July 14, 15, and 16, at the usual time (noon pacific). In my experience the high salesranks we are seeing this year (for the most popular string books) are unprecedented. Could indicate a shift in public perception. Now string not thought as jazzy as, say, 5 years ago. Possibly a different sort of pop-sci physics book (non-string this time) taking over the market.

To keep track of the popular physics book market (Amazon salesranks) I show here some mid-month salesrank averages for the string top five. I plan to take the average of noon readings on the 14, 15, 16 of July, extending this record.

As a spot check, at noon on 19 June the stringy topfive average was 8558.0, in line with the much higher salesranks we have been seeing this year. The five most popular titles (elegant, fabric, black hole, parallel, hyperspace) ranked 2041, 7733, 8153, 12161, 12702, averaging out to 8558.
This may not seem significant, but I just checked the Amazon.de standing of a German book "Before the Big Bang"
http://www.amazon.com/dp/3100039106/?tag=pfamazon01-20
which is the first popular all-LQG book, and it showed up as a leader among the theoretical physics and cosmology bestsellers.

Nr. 1 in Bücher > Fachbücher > Physik & Astronomie > Theoretische Physik
Nr. 4 in Bücher > Fachbücher > Physik & Astronomie > Astronomie & Astrophysik > Kosmologie

The Amazon price is 20 Euro. It came out April 2009 over a year ago, still doing OK saleswise. The paperback edition is scheduled to come out September 2010, in three months. Amazon price 10 Euro (or 9.95 :smile:) and my guess is that it will also do OK. This book applies LQG to cosmology (it is a "Loop quantum cosmology" book, presenting models and arguments for the "big bounce" conjecture.) In the Usa market there has not been an all-LQG book, so far. Only books which covered several different approaches to quantum gravity, including Loop. The new German book is more focused, which is what makes it different.

To keep track of the popular physics book market (Amazon salesranks) I show here some mid-month salesrank averages for the string top five. I plan to take the average of noon readings on the 14, 15, 16 of July, extending this record.

January2007 4396
February2007 3789
November2008 3711
July2009 6485
March2010 7521
April2010 11983
May2010 6884
June2010 9731
July2010...?...

As another spot check, at noon 26 June the five most popular stringy books (elegant, fabric, hyperspace, parallel, warped) ranked 3202, 5278, 8967, 10816, 28655 for an average of 11383.6. It seems obvious that there has been a sharp decline in string popularity compared with the way the pop-sci book market looked in 2007 and earlier. This follows the earlier decline in professional interest as shown by the drop in citations to recent string research papers.

================================
Here's the string publication picture for the first five months of successive years.

It's helpful to recall the recent precipitous drop in citations of string research papers by string theorists themselves. The loss of professional interest in that type of research can help us understand the falling off of public interest in popular accounts. More precisely there has been a drop-off in the proportion of highly cited recent papers* which are on string topics, something I reported back in mid-Febrary 2010:

marcus said:
Here are links to Spires "top-50" listings
for 2008:
http://www.slac.stanford.edu/spires/topcites/2008/annual.shtml
for 2009:
http://www.slac.stanford.edu/spires/topcites/2009/annual.shtml

These are reported in articles such as: "Top-cited high-energy physics articles during 2008",
from SLAC-Stanford's online magazine Symmetry-Breaking
http://www.symmetrymagazine.org/bre...ited-high-energy-physics-articles-during-2008

String citation standing in the Spires top 50 HEP list has dropped. In the early 2000s it would often happen that around twelve out of the top fifty would be recent string papers. And the rankings of those twelve were often near the top of the 50 list. By recent, I mean papers that appeared in the past five years, counting back from the year in question. For the year 2008, it would be 2004-2008.

In 2008 four of the fifty top-cited HEP papers were recent string. And the four recent string papers that made the top 50 list had average citecount of just under 180, which put them down near the bottom of the list. Their ranks were 37, 44, 48, 49.

In 2009 only one of the top-cited HEP fifty, was a recent string paper. And it was number 33, two thirds of the way down the list...

Details were given in this post:
https://www.physicsforums.com/showthread.php?t=372499
Here's the link to Spires topcites listings:
http://www.slac.stanford.edu/spires/topcites/2009/annual.shtml

*high energy physics (HEP) research papers
========================
The loss of interest which shows up in the popular book market is to some extent correlated, perhaps with a lag of a few years. These are 3-day averages of the top five string books' salesranks, taken right around the 15th of each month:

January2007 4396
February2007 3789
November2008 3711
July2009 6485
March2010 7521
April2010 11983
May2010 6884
June2010 9731
July2010...?...

For consistency, I take the readings at noon Pacific time. Some recent spot checks at noon on various days:

3July 9402
5July 10097
6July 6518

As of 5 July, the string top five (parallel, elegant, hyperspace, fabric, black hole) ranked 5835, 8434, 8675, 13056, 14486 for an average of 10097.2
Noon 6 July string top five (elegant, parallel, hyperspace, fabric, warped) 2166, 4263, 4657, 5482, 16020 for an average of 6517.6

To get rid of some of the random fluctuation, the figure that will be recorded for the mid-month July will as usual be an average of three days in the middle of the month. 14, 15, and 16 July.

Unusual surge in sales, compared with what it's been for the past month or so, could be related to a media event like talkshow appearance or airing a TV series.

The issue of citation counts keeps coming up. The precipitous decline in citations (by string theorists themselves to recent papers by their colleagues) is a remarkable indication of the declining value and interest of recent research.
Here are links to Spires "top-50" listings
for 2008:
http://www.slac.stanford.edu/spires/topcites/2008/annual.shtml
for 2009:
http://www.slac.stanford.edu/spires/topcites/2009/annual.shtml

These are reported in articles such as: "Top-cited high-energy physics articles during 2008",
from SLAC-Stanford's online magazine Symmetry-Breaking
http://www.symmetrymagazine.org/bre...ited-high-energy-physics-articles-during-2008

String citation standing in the Spires top 50 HEP list has dropped. In the early 2000s it would often happen that around twelve out of the top fifty would be recent string papers. And the rankings of those twelve were often near the top of the 50 list. By recent, I mean papers that appeared in the past five years, counting back from the year in question. For the year 2008, it would be 2004-2008.

In 2008 four of the fifty top-cited HEP papers were recent string. And the four recent string papers that made the top 50 list had average citecount of just under 180, which put them down near the bottom of the list. Their ranks were 37, 44, 48, 49.

In 2009 only one of the top-cited HEP fifty, was a recent string paper. And it was number 33, two thirds of the way down the list. The paper in question was cited 222 times.

I've been using Amazon salesranks as a rough indicator of public interest in string (as compared with other pop-physics, or simply in general).
So far I have not been including the KINDLE e-book sales, because Amazon lists their salesranks separately and gives no clear indication of how to compare e-book ranks with ordinary book ranks.

Also in past years the e-book sales have not seemed (from what I can tell) to be large enough to compete significantly for places in the top five.

However I looked into this recently and have the impression that the Kindle e-book editions of string books (e.g. by Brian Greene) have now become an important part of the market and should be counted among our "top five", and also that one can get an adequate estimate of what the salesrank would be simply by using the rank of the next real BOOK in the cosmology bestseller list (where all the popular string titles are to be found together with favorites like the Hawking books, Carl Sagan, and so on.)

As of noon 10 August the five most popular string books were elegant, fabric, e-fabric, e-elegant, parallel.
Using the "next real book" estimate their salesranks were 4237, 4562, 11093, 14068, 14558, for an average of 9703.6

If we did not include e-books, the stringy topfive average salesrank would be higher, because the list of top five would have to include a couple of titles of much less popular books.

As explained in the previous post, I've started including e-book editions (along with the usual hardbound and paperback) in determining the stringy top five. Since Amazon does not publish the overall salesranks but keeps "books" and e-books separate, I have to estimate the salesrank equivalent. I do this using the "cosmology bestseller" list where all the popular string books appear together with other such as Hawking, Sagan etc.
Simply take the salesrank of the next "real book" in order.

Using this extimate the top five stringies as of noon 12 August were
e-fabric, elegant, e-elegant, fabric, parallel and their ranks were
6223, 6662, 12462, 12835, 18811, for an average of 11398.6

Amazon has identified a pop-cosmology market consisting of lay-reader big vision books about the universe and what fundamental particles it is made of and how it came to be--plus cool awesome stuff like black holes and time travel---they gather all that in the "cosmology" bestseller list. The popular string books are there, so it makes it easy to find their salesranks. Have a look at the list!
https://www.amazon.com/gp/bestsellers/books/13449/&tag=pfamazon01-20

Here are the midmonth average salesrank readings that I've recorded over the past years. Normally noon readings on the 14, 15, 16th of any given month. I might start averaging 5 readings: like 13, 14, 15, 16, 17th. The idea is to record the average salesrank of the five most popular stringy books. When I started checking this number was typically around 3000-4000. Now, with declining interest and popularity, it tends to be higher (although events like a science fair or publicity surrounding a new TV series on the Universe can bring it down around 5000-6000 from time to time.)

...Here are the midmonth average salesrank readings that I've recorded over the past years. Normally noon readings on the 14, 15, 16th of any given month. I might start averaging 5 readings: like 13, 14, 15, 16, 17th. The idea is to record the average salesrank of the five most popular stringy books. When I started checking this number was typically around 3000-4000. Now, with declining interest and popularity, it tends to be higher (although events like a science fair or publicity surrounding a new TV series on the Universe can bring it down around 5000-6000 from time to time.)...

Here are links to Spires "top-50" listings of the most-cited high-energy physics papers
for 2008:
http://www.slac.stanford.edu/spires/topcites/2008/annual.shtml
for 2009:
http://www.slac.stanford.edu/spires/topcites/2009/annual.shtml

What I've been watching here is how many of the top 50 papers are recent string---recent in the sense of having appeared in the past five years, counting back from the year in question. For the year 2008, it would be 2004-2008.
In the early 2000s it would typically happen that around twelve out of the top fifty would be recent string papers. And the rankings of those twelve would often be near the top of the 50 list.
In 2008 four of the fifty top-cited HEP papers were recent string. And the four recent string papers that made the top 50 list had average citecount around 180, which put them down near the bottom of the list. Their ranks in the top 50 were 37, 44, 48, 49.
In 2009 one of the top-cited HEP fifty, was a recent string paper. And it was number 33.

=====================String publication for the first seven months of successive years:
Here are some figures for the first seven months:

Jan+Feb+March+April+May+June+July figures as of 22 August: 3334, 3338, 3293, 2627 (preliminary, July is still not all catalogued.)Noon salesrank averages of string top five. Quite a bit of fluctuation lately, which may have to do with a new popular-audience book by Hawking scheduled to go on sale in a couple of weeks. Should raise public excitement regarding theories of the universe and related matters.

19 August 11443.0
20 August 11506.2
21 August 9355.6
22 August 6952.0
23 August 10516.2

The top five always seem to be from this list of six: fabric, e-fabric, elegant, e-elegant, parallel, hyperspace. For instance at noon 23 August the five most popular string were elegant, fabric, e-elegant, e-fabric, parallel, with respective ranks 6044, 6876, 11400, 13899, 14362 giving the average sbown here of 10516.2.

Though I have not yet seen much about the new Hawking book "Grand Design", I'm going to start provisionally counting it as stringy. According to some reports, it promotes the vision of M-theory as TOE. The book goes on sale 7 September, will presumably sell well, and will help improve the string topfive average (reducing the unusually large salesrank numbers seen of late).

So probably for a while the day's top five string books will tend to be drawn from this list of seven: grand, fabric, elegant, parallel, hyperspace, e-fabric, e-elegant.

A new Roger Penrose book is also due out in September, but since the book will not be in any sense stringy it will not affect our keeping track of this index of reader interest.

Just now (25 Aug) when I looked the top five (grand, fabric, elegant, parallel, hyperspace) ranked 2331, 6455, 9528, 17898, 19624 for an average of 11167.2
Checking again, at noon 26 August, grand, parallel, elegant, fabric, e-fabric ranked 373, 9768, 10368, 10404, 15695 for an average of 9321.6.
If the Hawking book turns out on balance NOT to be stringy (a judgment call) that would make the average string saleranks quite a bit larger.

It's been two weeks since I posted LQG research publication data, so I'll update:

So far despite a wave of orders for the new Hawking book (which pending review I will assume is stringy) the string topfive salesrank is still around twice what it was as recently as 2 years ago---suggesting a drop-off of interest. Some spot checks at noon on several days:

30 August 8040.2
31 August 9765.8
1 September 9615.2
2 September 9954.8

At noon on 1 September the five most popular string books (grand, elegant, parallel, fabric, e-fabric) ranked 659, 7540, 11299, 12111, 16467, for an average of 9615.2
At noon on 2 September the five most popular string books (grand, elegant, parallel, e-fabric, e-eleganty) ranked 9, 4249, 7533, 16321, 21662, for an average of 9954.8

To put this in perspective here are mid-month averages I happened to record in previous years, as well as some in 2010:

The whole string book market has been changed by a crop of new books that all seem likely to become very popular:

Shing-Tung Yau "The Shape of Inner Space" https://www.amazon.com/dp/0465020232/?tag=pfamazon01-20 Officially goes on sale 7 September 2010

John Gribbin's book "In Search of the Multiverse" https://www.amazon.com/dp/0470613521/?tag=pfamazon01-20 A new edition appeared 24 August 2010.

Hawking's book "The Grand Design" Officially goes on sale 7 September 2010.
https://www.amazon.com/dp/0553805371/?tag=pfamazon01-20
Advance orders have made it #1 book at Amazon.

Brian Greene's new title is scheduled to appear in January 2011 "The Hidden Reality--Parallel Universes and the Deep Laws of the Cosmos"
https://www.amazon.com/dp/0307265633/?tag=pfamazon01-20

Pop-string is suddenly huge!
The average salesrank of the five most popular string books has never been lower, as far back as I can remember. Here are some noon readings, 6 September

grand 2
abridged audio grand 1134
yau 1269
elegant 1944
multiverse 2005

That makes the topfive average 1270.8
I've been used to seeing numbers like 4000 (a couple of years ago) and 8000 (recently). So a topfive average salesrank of 1000 indicates unusually strong sales.

As far as I can see the huge public appetite is for books about the universe claiming to explain why it exists or how it came about, and more specifically multiverse books. And these multiverse books (all except the new Roger Penrose book) tend to devote a chapter or so to String Landscape and M-theory. At least I think they all do. I haven't seen Hawking's. So I count them as stringy even if that's not the main focus.

The titles to look out for, if you follow this new craze, are
Grand Design (Hawking Mlodinow)
Shape of Inner (Yau)
Search for Multiverse (Gribbin)
and eventually Hidden Reality (Greene) but that is not yet ready for sale.

The other indices I've been watching are essentially unchanged since the last update, so if curious just scroll back a few posts. What has changed remarkably is the pop-sci book market.

I am calling the new Hawking Mlodinow a "string" book because it promotes the idea that there is an "M-theory" (so far the actual theory is missing but perhaps someday it will be formulated) and that this theory describes a huge landscape of possible versions of physics and the book also promotes the unsubstantiated idea that a multitude of universes exist exhibiting all these versions of physics.

This "Multiverse" idea conveniently hides the string theoreticians' failure to explain the universe that we actually see--to offer a unified coherent and predictive theory of the world nature gives us. It elevates string/M to an imaginary throne: the "Law Governing the Multiverse".

So even though the book has little concrete to say about string theory and deals with (so far nonexistent) M in only the vaguest terms, because of its M/multiverse message I count the current Hawking as stringy. Because of its popularity the index we are watching--the average salesrank of the five currently most popular string books--has improved enormously. It is now down around 1000 and has been so for several days. I will record whatever it is at mid-month. Here is a spot check indicating what to expect:

At noon 10 September the topfive stringy books (grand, e-grand, Yau, Gribbin, audio-grand) ranked 2, 290, 1529, 1734, 1898, for an average of 1090.6. Parenthetically here, by Yau I refer to the "Shape of Inner Space" book, and by Gribbin I mean his "In Search of the Multiverse". Besides the conventional format edition of "The Grand Design", there is an electronic edition and an abridged audio edition--as you can see, all three are doing well.

To put the 10 September number in perspective I will show it with some mid-month averages recorded previously:
Code: 
Midmonth average of string topfive salesranks
(when possible, recorded at noon on the 14th 15th, and 16th of each month)

June2010:        9731
July2010:        8461
August2010:      9606

Spot check for comparison
10 September      1091

Popular string book market completely changed.
For most of the past 4 years the string top five, the list of five most popular string books, has been dominated by Greene and Kaku, always the same four books. At noon today 14 September it was Hawking and Yau. Grand, e-grand, Yau, audio-Grand, elegant ranked 2, 81, 812, 1584, 1844 for an average of 864.6

This is a huge jump in popularity associated with the Hawking book that just came out. I don't think "Grand Design" actually teaches much about string, but I count it as stringy because it promotes "M-theory" as the law of the imagined "Multiverse". All the different solutions of M-theory correspond to different versions of physics and (assumed to exist) different universes.
It seems to me this is very stringy thinking and the book should be counted.

All 3 of its editions ( regular hardcover, audio*, and e-book) came out simultaneously, the beginning of this month, and all three are making the stringy topfive.

Today when I checked the top five (grand, e-grand, Yau, audio-grand, elegant) ranked
3, 32, 1145, 1318, 2769 for an average of 1053.4

The same number computed on three consecutive days at mid-month:

14 Sept 864.6
15 Sept 1260.8
16 Sept 1053.4

gave a mid-September average of 1059.6, which I have recorded above.

*earlier notices said the audio version was abridged---now I see it described as unabridged.
=====================

Just out of curiosity (although not needed for the mid-month record) I checked again on 17th. At noon the string topfive (grand, e-grand, Yau, audio-grand, elegant) ranked 3, 29, 1125, 1965, 2757 for an average of 1175.8.

Time to do a midmonth review of the popular book market to see how pop-string books are doing. Counting Hawking *Grand Design* as a string book because of its favorable mention of M-theory, though it may not teach anything very definite about the subject.

I recorded the average salesrank of the string top five---the five most popular stringy books as of noon on the day in question.

13 October 1332.4
14 October 1278.4
15 October 1544.4
16 October 1438.8
17 October ...

As an example, at noon on 15 October the top five (e-grand, grand, Yau, hyperspace, parallel) ranked 33,33, 965, 2565, 4126, for an average of 1544.4.

EDIT: At noon 16 Oct, the top five average was 1438.8.
