Sociology of Physics: comment and indices

AI Thread Summary
The discussion highlights the sociology-of-science implications within theoretical physics, particularly through the works of Ozzy Zapata and Roger Penrose. Both emphasize how intellectual trends, like string theory, can become expert fads, with Penrose's 2006 talk providing an engaging critique. Citation metrics reveal a significant decline in the prominence of recent string theory papers, suggesting a waning interest among physicists. Despite a stable publication rate, the drop in citations raises questions about the field's relevance and acceptance. Overall, these insights indicate potential shifts in the landscape of theoretical physics and its research focus.

Martin B's book is doing remarkably well! It came out in April 2009, so what we are seeing now is not merely the first rush of sales driven by publicity and reviews in the media when a book first appears. We are already 8 months on in the book's trajectory.

Züruck vor den Urknall ("Before the Big Bang") is the first popular book concentrating primarily on the Loop approach to quantum gravity and the early universe. Since it has shown some potential in the German market, the question arises as to how it might do in English translation (either in the Europe-wide market or in North America.)

The DESY librarians have recently found a half-dozen more 2008 artices to include in the Loop-related category. So both the 2008 and 2009 numbers have been creeping up. Neither can be considered as final.

Ordinarily at least once a year we check string citations, to detect any trend. For any given year, I focus on recent publications---appearing in the last 5 years---and look at citations occurring in that year. The Spires listing for 2009 could appear any time now, but we don't have it yet. Here for comparison is the listing for 2008, which appeared in January 2009.

I have removed non-string papers and papers which appeared before 2004. We are looking at a five-year window 2004-2008. The original Spires list contained 50 papers, many were string from the 1990s and many of the more recent papers were in non-string areas such as astrophysics. After eliminating non-recent and non-string, four papers remained.

The first number given is the number of citations the article received during 2008.
When the list for 2009 appears we will be able to compare.

Restricting to recent (past five years: 2004-2008) string papers we see that 4 recent string papers made the topcite 50 list. String citation standing has dropped. In the early 2000s it used to be that more like 12/50 of the top fifty were recent string. And the rankings were often near the top of the 50 list.
This year 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.

That was the 2008 list that came out in January of 2009. Now it is one year later. I suppose we may expect a similar list. Top 50 HEP papers for 2009. Hopefully it will come out soon so we can compare and inspect for change.

"Top-cited high-energy physics articles during 2008", dated January 14, 2009,
from SLAC-Stanford's Symmetry-Breaking
http://www.symmetrymagazine.org/bre...ited-high-energy-physics-articles-during-2008

String citation standing in the Spires top 50 HEP has dropped. In the early 2000s it used to be that more like 12/50: 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 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.

That was the 2008 list that came out in January of 2009. Now it is one year later and I suppose we may expect a similar list to appear: the Top 50 HEP papers for 2009. However as of now SLAC-Stanford has not yet published the list of
"Top-cited high-energy physics articles during 2009".

String citation standing in the Spires top 50 HEP has dropped. In the early 2000s it used to be that more like 12/50: 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 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 papers was a recent string one. And it was number 33, rather far down towards the bottom of the top-50 list. The paper in question was cited 222 times.

The benchmark used here for comparison is the average salesrank of the three currently most popular string books on the German market. One can see that Züruck, a Loop cosmology book, is doing approximately as well as the top three stringies (typically these are translations of two Brian Greene books and one by Lisa Randall.)

I made a spot check of how those two popular books were doing, today.

Züruck vor den Urknall (back before the big bang) is the first popular book in any language that is entirely (or even primarily) based on the Loop approach, so it is interesting to track how it is doing in the German market.

The Trouble with Physics gives brief descriptions of several non-string approaches quantizing geometry, but it does not adopt anyone in particular. The scope is broader. Since we do not know how various approaches will work out, the book is critical of the narrow concentration on string (especially by the research establishment in the Usa)

The Smolin book appeared in September 2006. It stayed near the top of the physics bestseller list for the first two years and is less prominent now, but still selling.

The German publisher has announced that a paperback edition for 9 Euro will be forthcoming, so some people are advance-ordering that instead of ordering the hardbound edition for 19 Euro. Or simply waiting. Sales apt to be slack until the paperback edition comes on the market--probably not until September 2010.

Around the first of the month I track the salesrank of two popular non-string books. I take readings as of 6 PM central European time, for the German book Züruck vor den Urknall, and at noon Pacific for the Usa book Trouble with Physics. As a benchmark for comparison the rank is compared with the 3 most popular stringy books on the German market, or to the 5 most popular on the Usa market. I average around the first of the month to get rid of some of the random fluctuation.

So far the numbers have been

Code: 
             Züruck    Trouble
27 February  0.181      0.353
28 February  0.885      0.236
1 March      1.345      0.513
2 March      0.213      0.693
3 March

On 1 March at 6PM Berlin time, Z ranked 13120 and the top three stringies (Stoff, Elegante, Verborgene) ranked 9217, 10409, 33295 for an average of 17640.3 making the ratio 1.345.
On 1 March at noon Pacific T ranked 13958 and the top five stringies (fabric, parallel, elegant, hyperspace, elegant paperback) ranked 3467, 3515, 8085, 9643, 11072 for an average of 7156.4 and ratio 0.513.

The particular interest of Züruck vor den Urknall (Back before the big bang) is that it is the first wide-audience book to appear in any language which is entirely based on Loop quantum geometry rather than string. The author describes what has been learned about how the geometry of the universe evolves in the Loop model.

On 2 March at noon Pacific T ranked 14680 and the top five stringies (fabric, parallel, elegant, little, hyperspace) ranked 4787, 5862, 8269, 15694, 16237 for an average of 10169.8 and a ratio of 0.693.

Today (3 March) at 6PM Berlin time, the German edition of Smolin's book was number one Theoretical Physics bestseller on the German market and Bojowald's Züruck vor den Urknall was number two.
http://www.amazon.com/gp/bestsellers/books/295042/&tag=

1. Die Zukunft der Physik: Probleme der String-Theorie und wie es weitergeht von Lee Smolin
Preis: EUR 24,95

2. Zurück vor den Urknall: Die ganze Geschichte des Universums von Martin Bojowald
Preis: EUR 19,95

3. Verborgene Universen. Eine Reise in den extradimensionalen Raum von Lisa Randall
Preis: EUR 10,95

4. Das elegante Universum: Superstrings, verborgene Dimensionen und die Suche nach der Weltformel von Brian Greene
Preis: EUR 9,95

5. Grundzüge der Relativitätstheorie von Albert Einstein
Preis: EUR 24,95
...

==endquote==

You can see that Smolin and Bojowald are doing OK even though their books are hardbound first editions and cost more than, say, the Brian Greene paperback.

Here are the salesrank ratios around the first of this month.

Code: 
             Züruck    Trouble

2 March      0.213      0.693
3 March      1.392      0.376
On 3 March at 6PM Berlin time, Züruck ranked 7337 and the top three stringies (Stoff, Verborgene, Elegante) ranked 5361, 11721, 13547 for an average of 10209.7 making the ratio 1.392.

The Trouble with Physics has a somewhat unusual record. It came out hardbound in 2006 and paperback in 2007, and has not sunk out of sight as rapidly as some similar books. Various new stringy books from around the same time have come out, by talented writers, and sunk into oblivion marketwise. Two (as I recall) by Susskind, one by Randall, and various mass appeal things like "string for dummies" or "complete idiot's guide to..." or "...demystified". Currently there is one by Gubser which romanticizes doing string research by comparing it with rock-climbing, and has a lot about himself and how he likes the mountains and adrenalin etc. Susskind's latest has a lot about himself and his travels and jogging and arguing with Stephen Hawking etc. So I'd say they are doing the right things to sell pop-sci books. But it is not catching on in the market as well as Trouble has. Seemingly not as durable.

I keep expecting Trouble to drop out of sight like the other recent popularizations written by scientists. But here is the recent record of how it's doing, after more than 3 years, compared with the topfive stringy benchmark.

=================

Another sociological index we could, I suppose, be watching is simply the salesrank average of the top five stringies. I have been using that as a benchmark (to compare Trouble's salesrank with) for the past few years, since it represents in a sense the size of the problem which Trouble has helped to correct: string overhype.
But that benchmark average may itself have some observable trend.
==================

A further index we could keep track of is attendance at the annual Strings conference.
It has been running at over 400 registered participants at least since 2005, when I started watching. This year, for various reasons, it is down to 193. So about half the usual.
I suppose as string research declines in interest there could be a tendency to hold the conference in humbler venues and that in turn could diminish attendance. Not sure about this, but we can see how it goes.

As of 25 March the Jan+Feb figures are 1125, 1132, 1117, 789
The figure for the first two months of 2010 should be fairly stable by now, based on past experience--but it seems low and could still increase as late arrivals are added to the database.

I mentioned we could watch the salesrank average of the top five stringies, which I've been using as a benchmark (to compare Trouble's salesrank with) for the past few years. That benchmark average may itself be slipping. To check for some trend in the stringy topfive average, I looked back to:
https://www.physicsforums.com/showthread.php?p=1986028#post1986028 November 2008

27 November 3335.6
28 November 3426.4
4 December 3922.8

The ten numbers I happened to find for November 2008 average tp 3669.6

I think you can see that the average salesrank of the five most popular stringies is now roughly twice that.

It recently occurred to me to keep track of the salesrank average of the five most popular string books (at noon on any given day).
I haven't always recorded that here but I do have these 10 figures for around March 2010

27 February 8843.0
1 March 7156.4
2 March 10169.8
8 March 6910.0
12 March 7981.4
13 March 6263.2
14 March 6847.6
18 March 9453.6
19 March 8297.0
25 March 10426.8

The average (of these salesrank averages) is 8234.9

So in the past year and a half, from November 2008 to around March 2010 the popularity of string books has declined by more than a factor of two according to this measure.
In November 2008 the average salesrank of the stringy top five was about 4000 (more exactly we got 3669.9) and around early March we found it was more than twice that, namely 8234.9.

Interesting rise indeed. I really don't have much of a serious clue but maybe the global crisis slightly setting people back and forcing them to reconsider what they are doing. Maybe the crisis makes look upon all the established structures with doubt and critisism, not only in society but also in science. since it becomes more clear that in times of limited resources, some extra thought may be needed and we can not afford to invest in the wrong questions.

Perhaps the critics, and questioning of - how have all the investments in ST made us more fit? - is even more relevant in the crisis days when it becomes more obvious that time and money is limited. We have to question how be choose to invest every single dollar. Ultimately it's self-preservation.

In think that type of reasoning is more likely to appear during bad times.

How was the pattern last summer? ie. could there be some summer/vacation phenomenon?

/Fredrik

This is an excellent post. I believe you are right that when economic crisis is constructed in one discourse, it spreads to others as a result of cognitive-emotional relations between people and their various distinct discourses.

Let's start by getting one thing straight, though. Choosing how to invest every single dollar is not self-preservation as much as it is hope of preserving economic status and systems that allow people to avoid doing labor that they don't want to do.

In one sense, science is a form of knowledge and it has its own economy of ideas and critique. On the other hand, academia involves organization various life activities of the human individuals practicing science, which is somewhat distinct from the actual practice of science itself.

To simplify some, first consider the lifestyle of some academic scientist you know. What do they own, eat, wear, drive, buy, sell, make, do, use, etc? Now trace the supply chains of any aspect of that lifestyle. When you arrive at some other individual who provides supplies and services for the academic scientist, ask yourself what would happen if that person practiced science.

If you can follow this example, you should be able to see that science can, at least in theory, be practiced by people working in non-academic situations.

Now, imagine all funding to science was eliminated and all scientists currently working in academia had to seek income in non-academic activities. If that was the case, the question is what would the right or wrong questions be to invest in, since economic productivity would be separate from scientific research.

So now you are probably saying, "yes but it's hardly possible to prepare and serve food to customers and clean up after them while doing good scientific research." This is where the relationship between economic crisis and academic investment really emerges.

The operative question is what is sacrificed economically in order for individuals to devote all their working hours to science or other academic endeavors? The answer depends on what each individual is capable of doing besides research and what economic demand pressures are pushing divestment in academia and why?

Cynically, I would say that many people have lost the ability to approach economy as a big picture, if they ever had that ability to start with. All such people know is that the squeeze is on them to generate money for someone else and they want money for themselves so they can spend it to get other people to do and make things for them.

In the bigger picture, though, the truth is that there is no scarcity of resources at all. In fact, prices fall and unemployment rises precisely because of overproduction and surplus. Nevertheless, people continue to want to make more money for reasons such as paying off debt and gaining more purchasing power.

Some people who want to make more money do it by investing in themselves and use their own labor to make goods or services to sell to others. Some of the same people, but also others, try to invest the money they have in others to make more money that way. Other people try to make money by convincing investors that they will be able to multiply their money if they pay them to do it. This is where it starts getting tricky.

Imagine I am in debt or just want to make some money and you are in the same position as me, but you have some money to invest. Neither of us really knows what is needed to produce for the economy, so I decide to come up with an idea for you to invest in, with the hope of making more money for both of us. But what if there is no more money to make?

So this is where the question becomes how far people are willing to go to try to squeeze more money out of the economy when there's none to squeeze. Presumably, every academic job could be eliminated until administrators and personnel emerged with reasons that their work will generate revenues for the institutions.

Then, as long as the revenue-plans aren't working, people are disciplined and fired to stoke the fire of getting them to generate revenues. It makes you wonder why no one comes forth with the big picture of how economy actually works and why it is not possible to make money under certain circumstances and how production and consumption is able to continue despite the economic crisis.

The reason why this big picture doesn't come out, I think, is because no one who sees economics purely in terms of generating more revenues and jobs wants to think about the fact that the revenues and jobs are nothing more than structuring mechanisms for producing the goods and services that are consumed.

If they did, they would realize that money becomes practically unnecessary in a free-market where significant abundance has been reached. Logically, supply-side competition drives prices down to levels so low that consumers and businesses become able to freely explore various production and consumption activities until new forms of scarcity emerge, which create new high prices which form an incentive for competition and production of these products and services.

Of course, this has happened in the form of growth of certain sectors, which are where jobs become available. These are mostly service jobs designed to cater to people who have nothing better to do than leisurely cruise around expending resources and money. If such people would conserve their spending, the amount of service labor to be done would decrease, and there would be more freedom to pursue free scientific activities.

"Great," you say, "why didn't he just say that in the first place?" Well, I'll leave you with the problem of what happens when the scientists and academics who are free from working in service jobs are the ones consuming the goods and services that generate those jobs.

Is it fair for academics to complain about funding-cuts, when the cause of those cuts in the first place is related to the fact that they are spending money on goods and services that require personnel to produce them? Maybe though it's less the will to consumption as it is the will to profit, tax revenues, and jobs/income that is driving the big squeeze, though.

I mentioned we could watch the salesrank average of the top five stringies, which I've been using as a benchmark (to compare Trouble's salesrank with) for the past few years. If public interest in string research has declined then one would expect this number to increase. Salesrank is so to speak a measure of disinterest. (Other things being equal, the higher the rank, the fewer books are being purchased.) Here are some November 2008 data.

Another thing we sometimes watch is the string research publication rate. Here's a search at Harvard abstracts (keywords: superstring, M-theory, brane, AdS/CFT, compactification, heterotic) for the first parts of consecutive years, to spot any trend.

Well, Lisa Randall appeared on the Charlie Rose show, talking about the LHC startup and giving a huge boost to sales of her braney book, even the hardbound edition, which had almost disappeared from the top 100 physics bestseller list :biggrin:

The stringy top five today were parallel, warped hardbound, warped paperback, little, and fabric. The average rank was 4914.8 compared with 14108 for Smolin's book. So on 1 April the ratio was 0.35.At noon 2 April Trouble was 22249 and the stringy topfive average was 5584.6 making the ratio 0.25.
The stringy top five were elegant, parallel, hyperspace, warped, and fabric.

As a spot check, the same average currently, 10 April 2010, was 12586.4.

10 April 12586.4
11 April 10375.4

There does seem to have been a marked change in the popularity of string books over the past year and a half.
Before November 2008 the average salesrank of the five most popular stringies was typically under 4000. Commonly somewhere around 3000 or 3500. Such salesranks could come back, but at least for the past year or so they haven't been that good. Now one often sees 6000, 8000, even (as now) 10000. Recent ranks in the "five digits" so to speak.

The string popularity benchmark (average rank of 5 currently most popular) has become interesting in and of itself. It used to be around 3000-3500 when I was watching earlier, then as of November 2008 it was averaging around 3700. Now it seems to be growing, a possible signal of declining public interest in string books.

The five most popular string books (little, elegant, dummies, fabric, parallel) ranked 5407, 9219, 9787, 13441, 13483.

I'm following the stringy topfive average salesrank which back when there was more public interest in string used to be in the low 3000s---and was 3700 as recently as November 2008. As interest has declined this average salesrank has increased noticeably. Readings taken at noon Pacific:

String publication for the first three months of this year still looks low by comparison with past years. But it has come up slightly over the past week as late arrivals are added to the Harvard database.

2007: http://adsabs.harvard.edu/cgi-bin/n...txt_wgt=YES&ttl_sco=YES&txt_sco=YES&version=1

2010: http://adsabs.harvard.edu/cgi-bin/n...txt_wgt=YES&ttl_sco=YES&txt_sco=YES&version=1

This does a search at Harvard abstracts (keywords: superstring, M-theory, brane, AdS/CFT, compactification, heterotic) for the first quarter of consecutive years, to spot any trend.
As of 20 April, the Jan+Feb+March figures for four successive years were:
1664, 1643, 1563, 1270

=====
String pops used to be near the top of the Amazon physics bestseller list. Average salesrank of the five most popular tended to be in the 3000s---the November 2008 average was a respectable 3700. Recently the string books have drifted down the chart to around the 10000s---five figure territory. I don't know whether or not this signals a decline in public readership/interest, a permanent loss of share in the pop-physics market.

String publication for the first three months of this year should have come up by now, as late arrivals are enteried into the data base. It usually takes an extra month for the numbers to stabilize and it's now the end of April so it should have done so. But the figure still looks low.

2007: http://adsabs.harvard.edu/cgi-bin/n...txt_wgt=YES&ttl_sco=YES&txt_sco=YES&version=1

As of 29 April, the Jan+Feb+March figures for four successive years were:
1670, 1643, 1583, 1316

=====

At noon 28 April Trouble ranked 15906 and the topfive stringies (fabric, hyperspace, parallel, elegant paperback, elegant hard) ranked 4180, 5309, 6932, 8223, 13216 for an average of 7572.0 making the ratio 0.48.

At noon 29 April Trouble ranked 24468 and the topfive stringies (hyperspace, fabric, parallel, elegant paperback, elegant hard) ranked 3287, 4951, 8222, 9023, 9119 for an average of 6920.4 making the ratio 0.28.

Time to set up for checking string publication for the first four months of successive years:

2007: http://adsabs.harvard.edu/cgi-bin/n...txt_wgt=YES&ttl_sco=YES&txt_sco=YES&version=1

As of 1 May (which is too early to get a stable 2010 number) the Jan+Feb+March+April figures for four successive years were:
2044, 2034, 1914, 1565=====
On the popular physics book market (Amazon salesranks):
Noon 29 April topfive average 6920.4 and trouble 24468 for a ratio of 0.28.
Noon 30 April topfive average 7928.2 and trouble 34183 for a ratio of 0.23.
Noon 1 May topfive average 6964.4 and trouble 30318 for a ratio of 0.23
11AM 2 May topfive average was 6222.8 and trouble 17748 for a ratio of 0.35 (can't check at noon today, 11:04 AM closest I can do)

on 2 May, for example, (graduation presents for youngsters?) the string top five were all Kaku and Greene: hyperspace, parallel, elegant paperback, fabric, elegant, in that order. :-D. More serious books not selling.

By good fortune I was home and able to check salesranks at noon today. Had not expected not to be able to. So I can correct the previous post.

Noon 29 April topfive average 6920.4 and trouble 24468 for a ratio of 0.28.
Noon 30 April topfive average 7928.2 and trouble 34183 for a ratio of 0.23.
Noon 1 May topfive average 6964.4 and trouble 30318 for a ratio of 0.23
Noon 2 May topfive average was 6965.4 and trouble 20256 for a ratio of 0.34
Noon 3 May topfive average was 6546.6 and trouble 62031 for a ratio of 0.11

The 5 day average topfive salesrank (around 1 May) is 7065.0.
The 5 day average Trouble salesrank is 34251.2.
The ratio of the two 5-day averages is 0.21

So far the most highly cited LQG paper that has appeared in 2010 is one by Lee Smolin, 47 citations.
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.

2007: 1670
2008: 1643
2009: 1583

At this point the Jan+Feb+March numbers should be stable. Downward trend, apparently.
This is based on a search at Harvard abstracts (keywords: superstring, M-theory, brane, AdS/CFT, compactification, heterotic) for the first quarter of consecutive years.

For the first four months of successive years it is still too early to get a stable 2010 number. As of 2 May, for what it's worth, the Jan+Feb+March+April figures for the same four successive years were: 2044, 2034, 1914, 1565.

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:
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
...

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:

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.

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.

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.

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.
