Sociology of Physics: comment and indices

marcus · Aug 3, 2011

Not useful as a statistical index (or so I've concluded) but perhaps a handy snapshot of current topics in string research. Harvard abstracts database search using keywords: superstring, M-theory, brane, AdS/CFT, compactification, heterotic

First six months of 2010

First six months of 2011
http://adsabs.harvard.edu/cgi-bin/n...txt_wgt=YES&ttl_sco=YES&txt_sco=YES&version=1

The Spires database has cataloguing done by human librarians. The Harvard system seems simply to use occurrences of words in the title or abstract---tagging is done by machine in other words. Whatever the reason, the results are different.

Here's a Spires search using (human-applied) keywords "string model" and "membrane model":
2002:
http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+%28DK+STRING+MODEL+OR+DK+MEMBRANE+MODEL%29+AND+DATE+%3D2002&FORMAT=www&SEQUENCE= (1783)

2011:
http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+%28DK+STRING+MODEL+OR+DK+MEMBRANE+MODEL%29+AND+DATE+%3D2011&FORMAT=www&SEQUENCE= (500)

I think the point of a search like this is not to get "ALL" of some category of research paper that you imagine in your head and you think is the right definition of string research. The point, I guess, is to apply the same test repeatedly and see if there is change and see if you can understand it. Here the test is what the DESY librarians classify a certain way, and one can only hope that their criteria are stable over the years.

BTW at noon 3 August the salesranks of the top five string books (e-elegant, grand, hidden, e-hidden, e-grand) averaged 2202. Still a long way to go before that index gets back up to its pre-September 2010 levels, that pertained before the two big multiverse books appeared.

Among indices of professional research activity a small but interesting one is the number of Loop phenomenology papers (related to observational testing) that have appeared post-2008 (i.e. 2009 and later). This search picks up a number of them, probably not all. Testing (using observations of the early universe) is crucial. So even though this only involves a few dozen papers, it is an indicator to watch.

http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+%28DK+LOOP+SPACE+AND+%28QUANTUM+GRAVITY+OR+QUANTUM+COSMOLOGY%29+%29+AND+%28GRAVITATIONAL+RADIATION+OR+PRIMORDIAL+OR+INFLATION+OR+POWER+SPECTRUM+OR+COSMIC+BACKGROUND+RADIATION%29+AND+DATE%3E2008&FORMAT=www&SEQUENCE=ds%28d%29

Here's a Spires search tracking Loop gravity research publication using DESY keywords for spinfoam, loop quantum gravity, loop quantum cosmology. Evidently the figure for 2011 is incomplete. I made the search for the same years tabulated for string in the preceding post, just for comparison's sake.

2002 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2002+&FORMAT=WWW&SEQUENCE= (25)
2009 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2009+&FORMAT=WWW&SEQUENCE= (142)
2010 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2010+&FORMAT=WWW&SEQUENCE= (154)
2011 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+DK+SPIN%2CFOAM+OR+QUANTUM+GRAVITY%2C+LOOP+SPACE+OR+QUANTUM+COSMOLOGY%2C+LOOP+SPACE+AND+DATE+%3D+2011+&FORMAT=WWW&SEQUENCE= (112)

The possible significance here is not the absolute numbers but the change over time, assuming the librarians apply their keyword categories consistently each year. DESY keywords are applied by hand, not by machine. You probably can't get ALL the papers you imagine to be in whatever category, but you can see how the number changes.

Here's a Spires search using the DESY library's keywords "string model" and "membrane model":
2002 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+%28DK+STRING+MODEL+OR+DK+MEMBRANE+MODEL%29+AND+DATE+%3D2002&FORMAT=www&SEQUENCE= (1783)

2010 http://www-library.desy.de/cgi-bin/spiface/find/hep/www?rawcmd=FIND+%28DK+STRING+MODEL+OR+DK+MEMBRANE+MODEL%29+AND+DATE+%3D2010&FORMAT=www&SEQUENCE= (935)

This is as of 13 August, evidently the 2011 figure will increase as the year progresses.
If you want a very rough estimate of the final figure you can multiply the current one by 12/7.5 since at this point about 7.5 of the 12 months are in.

For other indices connected with professional research and faculty jobs, see post #241 in this thread:

The main indicator of wide audience interest we have been watching is the string topfive Amazon salesrank average.
At noon 13 August the five most popular stringy books (grand, e-elegant, e-grand, e-hidden, hidden) ranked 752, 1198, 1501, 2408, 3547 for an average of 1881.

The corresponding topfive average at noon 12 August was 1757. I'm planning to record a midmonth average as I've done in the past.

12 August 1757
13 August 1881

The most popular stringy books tend to involve imagining multiverses rather than explaining string theory per se. Stephen Hawking's The Grand Design is especially popular in the wake of his prominent role in a TV series called "Curiosity".

Here's what that index has looked like for the past year. September 2010 was when Hawking's grand design multiverse book came out.

Learning how to use Inspire search, which will be replacing Spires.

type this into the box:
keyword:"quantum gravity: loop space" OR "quantum cosmology: loop space" OR "spin: foam" and date=2011

You get this:
http://inspirebeta.net/search?ln=en...n_search=Search&sf=&so=d&rm=&rg=25&sc=0&of=hb (161 found)

161 records are found, presumably will increase between now and yearend. Perhaps, since about 8/12 of the year is over now, it could increase to something like 12/8 of present size. And perhaps not. Hard to guess.

Let's do that also for the years 2005 through 2010

You can look back and compare. This autumn (perhaps as late as November) PBS will be coming on with a Brian Greene special (we've seen flashy visual effects previewed). This time the basis is his Fabric of the Cosmos. This will boost sales of the book.

I'm still learning how to use Inspire. Here is a corrected version of what I posted yesterday.

Inspire will double count if you aren't careful with the settings--a paper has two dates the year it first appeared (say as preprint on arxiv) and the final version date (say as published in journal). What Inspire does is good but you need to consciously select which type of date to use in finding the papers of that year.I did another spot check of the popular string book market. At noon 27 August the top five books (grand, e-elegant, hidden, e-grand, elegant) ranked 1431, 2014, 2970, 4065, 4291 for an average of 2954.

If you scroll back to post #250, you'll notice that this salesrank average is comparable to what we saw back in 2007-2008. But not yet on par with levels seen in 2009-2010 prior to the September appearance of the Hawking multiverse book.

A simple way to estimate the annual rate is to type "1 1 2011" (1 January 2011) into this:
http://howlonguntil.net/
It will tell the number of days since beginning of year. In this case, today being 7 Sep, it says 250.
So multiply the number of papers so far by 365/250.

In this case 129*365/250 = 188

Just a rough estimate. Could be 150 or 160. But gives an idea.

In this case 134*365/260 = 188
The annualized rate for the first 260 days of the year has been noticeably higher than the rate in past years. I've no idea if this will persist, or how much to expect it to subside.

In the pop science market, multiverse books continue strong. The combined string topfive salesrank for 17 September was 1793 making the mid-month average for September 2181. Here's what the past year or so looks like.

142*365/273 = 190
749*365/273 = 1001

Already by 1 October there were from the LQG-SF-LQC community as many papers (142) as appeared in the whole of 2008. Something must be stimulating this increase of activity. The year is only 3/4 over.

It may be the perception that the correct smooth limit has been achieved. By this I mean the limit where one keeps the macroscopic size of the region constant and let's the discreteness parameter gamma go to zero--a bit like what happens to discrete chunks in the kitchen blender. Seeing this work out right could, I guess, motivate researchers with a sense of possibilities opening up.

There was the August paper by Magliaro Perini and the September one by Bianchi Ding.
http://arxiv.org/abs/1108.2258"
http://arxiv.org/abs/1109.6538"
Also important developments by Lewandowski's Warsaw group and by Dittrich's group at Golm.
Insiders would have had advance inkling of these results which can be seen as signposts of success for the program.

Again, at noon 1 Oct the pop-string top five (e-elegant, grand, e-grand, hidden, e-hidden) averaged a salesrank of 2536.

marcus · Oct 7, 2011

The picture is largely unchanged from 6 days ago. At noon the five most popular stringy books
(primarily about multiverse, not string/M itself) were grand, e-elegant, hidden, e-hidden, e-grand, and ranked 1746, 1922, 2097, 2840, 3962, for an average of 2513.

DESY has not gotten around to cataloging the new Loop papers so the count is still 142 as it was on 1 October. But new String/M papers have been registered so the count there has changed slightly. The annualized rates are

142*365/279 = 186

As of 8 October the annualized rate is 148*365/280 = 193
So far this year the rate seems noticeably higher than in past years.

Just today DESY library also logged a bunch of string/M papers bringing the previous count up to 773 so the annualized rate is
773*365/280 = 1008
It would seem the tentative lesson learned is "Wait for Saturday." Then DESY numbers will be more complete (assuming this pattern persists.)

Ranks tended to be much higher in the couple of years before the appearance of the Hawking and the Greene multiverse books. Books which invoke the multiplicity of possible versions of physics inherent in string/M but which do not go much into string by way of specifics. To see the history of this index back to some sample months in 2007, go back to post #250.

Four new Loop gravity papers have appeared in the last few days, but have not yet been logged by DESY, which updates only about once a week. So the total for 2011 so far is 152 instead of 148.
Annualized: 152*365/286 = 194
Compare with the previous post #263
The annualized rate for Loop research remains somewhat higher than it has been in past years. Not clear why or whether this will persist through yearend.
FWIW: 776*365/286 = 990

Just as some random string Sociology, or related cultural Anthropology there was a great CERN Christmas party in 2006 that deserves to be remembered. I will get the link.

The blogger, whose web-handle is Jester, especially liked the string "Pope" who was dressed in gaudy ecclesiastical garb and who piously intoned: "Our Witten which art in Princeton..."

"...Give us this day our daily string,
And forgive us our theory,
As we forgive those who do phenomenology.
Lead us not into experiment,
And deliver us from tests.
For thine is the arXiv,..."

A new PBS NOVA series with Brian Greene has started, this time based on "Fabric of the Cosmos". High-power computergraphic visuals + lots of wonders. Sales of string books are strongly up. The top 5 are actually all Brian Greene.

As of noon 4 November the five most popular stringy books are fabric, e-fabric, hidden, e-hidden, and e-elegant, with an average salesrank of 1135.
See post #265 for a longer-term record of the topfive average salesrank.

================
Baylor University in Texas has hired a string theorist! According to the Theoretical Particle Physics Jobs Rumor Mill 2011 saw about 13 first-time faculty hires in Usa and Canada, but until recently it appeared that none of the hires were in string. However it is now reported that Antonino Flachi has been hired to a first-time faculty position at Baylor.
http://particle.physics.ucdavis.edu/rumor/doku.php?id=archive:2011
http://particle.physics.ucdavis.edu/rumor/doku.php

Annual first-time faculty hires (US and Canada) in HEP theory as a whole, and in string, averaged over 3 year periods, with prelim. estim. for 2011

Code:

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

The three year period 2008-2010 showed an average annual rate of 13 hires per year overall in High Energy Physics Theory. So 2011, with 13, shows no change in overall hires. The annual rate of string hires does seem to have slacked off some, but is not zero (as appeared earlier).
A more detailed tabulation by a prof in the Toronto physics departent:
http://www.physics.utoronto.ca/~poppitz/Jobs94-08
Some comment on the trends:
http://www.math.columbia.edu/~woit/wordpress/?p=3715

In case you haven't heard of Baylor and are curious, "Baylor University in Waco, Texas, is a private Baptist university, and a nationally ranked liberal arts institution."

The current president of Baylor University is Kenneth W. Starr, of Whitewater/Lewinsky/Prop 8 fame.

======================
String and Loop research publication shows some change from last year. This year's figures now seem roughly stable:

Hi Pythagorean, those topics strike me more as MATH topics. In this thread I am focused more on some indicators of where fundamental physics (geometry and particle physics) is going.
At various times in the past I've been interested in some of what you mention. Computational complexity for one thing. My wife did her thesis in that, and some friends were researching in that area. Plus it is just intrinsically interesting.

But I can't respond to those themes in this thread---it would just go way off topic. You could start a thread in one of the MATH forums. Or even in one of the Physics forums. You might get some discussion there. I'm not sure where the best place would be.

Here, even though the string fad in theoretical physics may be largely finished and there might be declining interest, I want to keep on consistently keeping track of some things.
In the popular book market (which does not reflect professional research trends) there is again an upsurge in sales of stringy books.

I want to record the noon salesrank readings for a few days around 15th November.
The stringy top five (fabric, hidden, e-fabric, e-hidden, grand) ranked 569, 798, 1074, 1132, 1165 for an average of 948.
The surge in sales has been associated with a new Brian Green Nova series based on "Fabric of the Cosmos" that just started this month, plus back in January his new book "Hidden Reality" came out. So most of the top five string books are various versions of these.

I want a November midmonth average to adjoin to this record:

Code:

I'm sure this is mostly semantic, but I was taught "nonlinear dynamics" in my "modern physics" courses (we were given a choice between GR and nonlinear and we unanimously chose nonlinear). It's mostly just an extension of "classical mechanics" but there's also:

http://en.wikipedia.org/wiki/Quantum_chaos" : a look at the interface and contradictions between classical and quantum mechanics.

Here, even though the string fad in theoretical physics may be largely finished and there might be declining interest, I want to keep on consistently keeping track of some things.

I understand; I do not mean to take away from the stringiness.

I am also interested in what the non-professional public thinks of complexity. Have you ever used google insights? You might find it useful in your analysis; for instance, if i compare popular search terms 'complexity' and 'chaos' I see that chaos is (naturally) a much more searched topic, but also that the rhythms are out-of-phase: 'chaos' sees peaks on the weekend (indicating the public is mostly googling the topic under one of it's many definitions) while 'complexity' peaks during the weekdays (indicating it's fellow researchers or students in physics and biology doing literature reviews and learning.)

marcus · Nov 13, 2011

Pythagaorean, thanks for the pointer to Google Insights. I have not yet gotten the knack or habit of using that, but maybe in time will. As I said I don't want to get into a discussion of complexity math, or of non-linear dynamics, here in this thread. But you can start a thread in one of the physics forums, if you wish. Sounds like it might be an interesting topic.

Since we are starting a new page for this thread, I will recap several of the indices we are tracking

Number of recent string papers making the top fifty in the annual Spires HEP topcite list

Code:

recent work highly cited in year  12       6       2       1       1       0

This gauges the quality/significance of current work by how much it gets cited by other researchers. Here a paper is counted as recent if it appeared in the previous five years.

I'm trying to get an InSpire search that will work as well as the old Spires search for LQG and LQC phenomenology, testing-related research. Here is one:
find d > 2008 and k loop space and (quantum gravity or quantum cosmology) and (gravitational radiation or inflation or power spectrum or cosmic background radiation or primordial)

The same with more to a page:

Stanford says they are going to turn Spires off. So we have to switch over. Here is the old Spires search:

This InSpire search is designed to turn up observational test-related Loop gravity/cosmology papers. It uses categories established by the DESY librarians. The publication date is 2008 onwards.
http://inspirehep.net/search?ln=en&...Search&sf=&so=d&rm=citation&rg=100&sc=0&of=hb
the DESY categories are gravitational radiation, inflation, power spectrum, cosmic background radiation, primordial---in conjunction with LQG/LQC.
So that is a 4-year stretch, and it finds 46 papers.

Reviewing the pop-string market, in March-August 2010 we saw a lowpoint in string book sales, with salesranks at their highest in several years. Then we saw a big rebound driven by some (incidentally stringy) multiverse books. Hawking "grand" came out in September 2010, Greene "hidden" in January 2011, and then in November 2011 there was another surge caused by the PBS NOVA Greene series based on "fabric".

Code:

November 2008:    3711
July 2009:        6485  
March 2010:       7521
April 2010:      11983
May 2010:         6884
June 2010:        9731
July 2010:        8461
August 2010:      9606
September 2010:   1060 
October 2010:     1344
November 2010     2220
December 2010     2705
January 2011      1252

September 2011    2181
October 2011      2563
November 2011     1243

To keep tabs on this I made a spot check. At noon on 29 November the topfive average was 2054 and at noon 30 November the five most popular stringy books (hidden, fabric, grand, paperback-hidden, e-elegant) ranked 794, 1124, 1492, 2874, 2999 for an average of 1857.
