Bringing forward several of the indices we are tracking. The following gauges the quality/significance of recent string research by how much it currently gets cited by (mainly other string) researchers. Here a paper is counted as recent if it appeared in the previous five years. Recent string research is less cited now than was the case formerly, say, ten years ago, and first-time faculty hiring of string researchers has declined.

A physicist at the U Toronto (Erich Poppitz) charts first time faculty hires in High Energy Physics Theory by year, in Usa and Canada. He keeps track of what fraction of the hires are in string, which fraction are in other branches of theory: cosmology, extensions of the Standard Model, and so on.
http://www.physics.utoronto.ca/~poppitz/Jobs94-08
His chart shows 11 HEP theory hires in 2011 with one being string.

Code:

period                    1999-2001    2002-2004   2005-2007    2008-2010    2011
annual HEP theory hires      18             24            23             13            11 
annual string hires              9              8              6               2              1

Here I have taken 3 years averages to smooth out Poppitz data and get an idea of the trends in annual rates of hiring. This shows the annual rate of overall HEP theory hires (for firsttime faculty positions) and also the part of that going to string theorists. It seems remarkable that a mere 10-12 years ago HALF the hep-theory jobs were going to string theorists. Not so today.

The 2012 hiring season is now in full swing. To update on the HEP theory job situation as reported by http://particle.physics.ucdavis.edu/rumor/doku.php (first time faculty positions, Usa and Canada), offers are out to 7 individuals in all, including two offers which have already been accepted.

It's interesting to see what areas of specialization are represented e.g. cosmology, phenomenology, lattice gauge theory,...etc among those who received offers.
http://inspirehep.net/search?p=find+a+Kaplan%2C+J
http://inspirehep.net/search?p=find+a+Slatyer%2C+T
http://inspirehep.net/search?p=find+a+Carpenter%2C+L

http://inspirehep.net/search?p=find+ea+Fan%2C+JiJi
http://inspirehep.net/search?p=find+a+Poland%2C+D
This sampling of research papers may give a suggestion regarding which *types* of HEP theory the departments doing the hiring want to reinforce, or perhaps one could say in which types they want to "invest" researcher-years of effort. It must have something to do with which lines of theory the physics department committee members think will "pay off".

I'm considering how to streamline the recording of midmonth salesrank averages. Perhaps I can save space and effort by only keeping figures for every four months: e.g. March, July, November.
The main emphasis of this thread has become the professional scene (as opposed to the popular book market.) The indicators I'm watching include

first-time faculty jobs (areas of theory where departments seem to want to hire)
focus of major conferences (speakers and titles of invited talks)
citations to current work (gauging the value/relevance of current research)

Public perceptions, as indicated by the changing salesranks of types of books, do not seem so relevant to the sociology within the physics profession, and the gradual shifts of interest and activity which are going on in the research communities.

Code:

Midmonth averages of string topfive salesranks
(recorded at Pacific noon on several days around the 15th of each month)
...
July 2009              6485
November 2009       NA
March 2010           7521
July 2010              8461
November 2010     2220
March 2011            349
July 2011              1257
November 2011     1243
March 2012           3235

So I'm going to see how it looks to skip months, and just tabulate salesranks for March July November. I will still CALCULATE averages for the intervening months, in case I want to go back to the old way, or in case some current trend seems interesting, but, tentatively at least, the longterm record will be pruned down.

There has been an unusual circumstance in connection with the Strings 2012 conference
About one month ago around March 31, the organizers added a page to their website designed to list the invited speakers and the titles of their talks.
http://wwwth.mpp.mpg.de/members/stri...ram/talks.html
But so far only one talk's title has been posted. The rest are still "TBA".
Normally looking down the list of titles of invited talks is a way of seeing what topics are currently of special interest to the community. Which areas have been especially active---what do the organizers think the conferees especially want to hear about?

For nearly a month now (as of today 26 April) the only talk title listed has been:

Hermann Nicolai---Alternative approaches to quantum gravity: a brief survey

Is this then what is most on string theorists' minds these days, and what they most want to hear about? :-D
It's a bit strange to see 39 invited speakers' names listed and still after a month all but one of their talks saying "TBA". The conference begins in just a bit under 3 months, on 23 July.

Update on the triennial Marcel Grossmann meeting (MG13) to be held the first week of July in Stockholm, it now has ABSTRACTS posted for 17 out of its 29 invited talks
http://www.icra.it/mg/mg13/invited_speakers_details.htm
These give an idea of what leading experts in relativity, gravitation, and cosmology are interested hearing about and discussing this year. It's a way to gauge where research is going at present.
So far I see no multiverse stuff or "something out of nothing" stuff. Maybe you can find some reference if you look closely. String as a whole seems downplayed, considerably less of it at MG than in past years. I gather it's less interesting now to professional cosmologists. Another window on the research scene is provided by the statements by the chairs of the special sessions.
Here's the list of special sessions:
http://www.icra.it/MG/mg13/parallel_sessions.htm
Here's what the chairfolks have to say:
http://www.icra.it/MG/mg13/par_sessi...rs_details.htm
For example the chairman of one of the two special sessions on Loop quantum gravity posted this about recent progress, status and what he wants the reports in his session to cover:
http://www.icra.it/MG/mg13/par_sessi...tm#lewandowski
The other Loop session focuses on Loop quantum cosmology. The chairman's statement is here:
http://www.icra.it/MG/mg13/par_sessi...ils.htm#pullin

It has now been a full month (as of 30 April) since the organizers of Strings 2012 put online this list designed to show this years 39 invited speakers and the titles of their talks.
http://wwwth.mpp.mpg.de/members/stri...ram/talks.html
and throughout that time the list has displayed one talk's title, and only one. The rest have been and are still "TBA".
The sole title listed has been:
Hermann Nicolai---Alternative approaches to quantum gravity: a brief survey
Normally looking down the list of titles of invited talks at a major conference is a way of seeing what topics are currently of special interest to the community: which areas have been especially active and which the organizers think those attending the conference are most interested in hearing about.
It could be that what is most on string theorists' minds these days, and what they are most concerned to hear about is precisely what Hermann Nicolai has chosen and prepared to discuss.
It's a bit unusual to see 39 invited speakers' names listed and still after a month all but one of their talks saying "TBA". The conference starts 23 July.

I'm tryng out the idea of just recording of popular stringy book sales on a once every four months basis. So far about all the record shows is a huge jump in popularity with the appearance of the multiverse books Grand Design and Hidden Universe (by Hawking and by Greene respectively) in September 2010 and January 2011.
Even though it's not for the record I'll take a midmonth average for May as a spot check to see how things are going.

A. Karch* Recent Applications of the Gauge/Gravity Correspondence to QCD and Condensed Matter Physics

In case anyone's curiosity is piqued by Gary Horowitz' title, it echos this recent paper:
http://arxiv.org/abs/1204.0519
Optical Conductivity with Holographic Lattices
Gary T. Horowitz, Jorge E. Santos, David Tong
(Submitted on 2 Apr 2012)
We add a gravitational background lattice to the simplest holographic model of matter at finite density and calculate the optical conductivity. With the lattice, the zero frequency delta function found in previous calculations (resulting from translation invariance) is broadened and the DC conductivity is finite. The optical conductivity exhibits a Drude peak with a cross-over to power-law behavior at higher frequencies. Surprisingly, these results bear a strong resemblance to the properties of some of the cuprates.
22 pages, 10 figures

"cuprates" makes one think "high temperature superconductor" (mentioned in conference talk title).
http://en.wikipedia.org/wiki/High-te...ivity#Cuprates
Recalling several participants noted that most talks at Strings 2011 had remarkably little to do with strings and branes, this window of the topics to be featured at Strings 2012 so far tends to confirm that impression and continue the trend.

Job situation basically unchanged from two weeks ago as reported 16 May in post #317. First-time faculty offers to 10 HEP theorists, none specialized in string (most in either cosmology or LHC phenomenology.)

A physicist at the U Toronto (Erich Poppitz) charts first time faculty hires in High Energy Physics Theory (Usa and Canada) by year. He keeps track of what fraction of these are in string, and which fractions are in other branches of theory.
http://www.physics.utoronto.ca/~poppitz/Jobs94-08
His chart shows 11 HEP theory hires in 2011 of which one was string.
It now looks as if 2012 will be a repeat. Offers have gone out to 11 HEP theorists so far this year, including one string theorist.
Up through 2010, the annual rates shown are smoothed by averaging over 3 years intervals.

Code:

HEP theory hires   18         24          23          13        11     11
