Using Zotero, pt 6.

For some time now, I’ve been using Zotero 1 because I had difficulties with Microsoft Word 2008 crashing using Zotero 1.5 and the alpha version of the Word plugin. Now, trying out the latest versions of the Word plugin and Zotero (2.0 beta) and so far it works!

BSHS conference in July

I’m going to the annual conference of the British Society for the History of Science in Leicester 2-5 July (was a bit lucky with the dates for the conference, since I have a ticket to see Depeche Mode in Copenhagen on June 30). I look forward to going to the conference and also seeing Leicester, have never been there before.

Abstract for my paper:


The Lund Observatory Milky Way panorama and all-sky images in the history of modern astronomy

All-sky pictures have often entailed manipulated image technologies rather than mechanical objectivity, and have been used both in astronomical science and in popular astronomy. In this paper, several 20th century astronomical practices of representing the whole sky are discussed, particularly the Lund observatory panorama of the Milky Way (1955). Produced by an artist working for two years under the direction of professor Knut Lundmark, it was a mixture of astronomical photography, photometric measurements and artistic creativity; Lundmark simultaneously aimed for scientific correctness and aesthetic value. Produced just at the dawn of the space age with a growing interest in astronomy in publishing and the media, the image became widely used in popular astronomy, academic textbooks, television programmes, museum exhibits &c. Based on archival material at the Lund observatory, it is possible to follow the media history of this picture through several decades and discuss the role of images in post-war astronomical culture.

Posters in astronomy

There are types of artefacts from various epochs that each are sites worthy of exploration by the historian interested in the visual culture of astronomy; CCD shots by amateur astronomers of today, 14 inch glass plates exposed in 1950’s 1 m-class Schmidt telescopes, cinematography of protuberances and other solar phenomena first shot on 35 mm film then on video, engravings in large format in 18th century star atlases, 19th century photography such as the Carte du Ciel-plates, drawings of nebulae by the Herschels and their contemporaries: these are only a handful of the categories that are kind of obvious and have been discussed by historians of astronomy; much work still remain to be done on each of them.

But what about some types of pictures that might be not so obvious but that make up quite significant parts of the image-worlds of astronomers (both professional and amateurs)? What about posters?

When I became interested in astronomy as a young boy (I was born in 1967), I entered a culture with images that were food for thought and dreams, images in books, magazines and Viewmaster discs. There were colourful posters of Apollo rocket hardware and the moon on the walls of my boyhood room. As I moved through the educational system, astronomical posters were present: in gymnasium and at the university departments, observatories and planetaria I visited, studied or worked at.

Some of these posters are placed in educational contexts, but some were perhaps rather put there by astronomers for themselves, a bit like the small collections of old instruments often found on display in university departments (as trophies, like the old cannons you find outside of military installations, a metaphor used by Mats Fridlund long ago). Sky Publishing was only one of several firms supplying these kinds of large-scale images to professional and amateur astronomers, often on-sale at planetarium and museum shops and in ads in Sky and telescope.

I suspect that the astronomical wall poster has a history that is kind of interesting. There must be some literature on the subject. We’ll see what I find.

Galaxy Zoo 2

Classifying galaxies by morphology has normally been done by small teams of astronomers or individual astronomers, like Peter Nilson spending years classifying objects on the Palomar Observatory Sky Survey producing the Uppsala General Catalogue.

Galaxyzoo is another way to do classifications of galaxy morphology. The work of hundreds of thousands of astronomy enthusiasts is used. Astronomy has an old tradition of professional astronomers collaborating with amateur astronomers, and basically I see this project as something of an evolution rather than a revolution. It is pro-am collaboration in astronomy done with e-science methods.

Participants in Galaxy Zoo classify basic galaxy morphology - spiral or elliptical, bulge visibility, bar formations, interaction - on images from the Sloan Digital Sky Survey over the Net. The first part of the project seems to have been successful; 170 000 people or so participated, classifying some 40 million galaxies, and the team behind it has begun to get papers out: here, here, here and here.

Now Galaxy Zoo 2 has started, basically a re-run through parts of the first catalogue with a closer look at morphology; more data about each object is collected. Judging from the onslaught on the servers - the pages have been loading very slow since this morning - a lot of people try to participate (helped by recent exposure on the BBC).

Update: servers crashed but came up again, thanks to backup. (But the site is unreachable now, 19 February 9 am CET.)

Update 2: two million classifications in two days.

Scientific mashups


Perhaps it is easy to overtheorize a phenomenon such as mashups, making too much out of it, overstretching its use as metaphor. For one thing, while musical mashups sometimes can be “official” - such as when Kylie Minogue performed a mashup of her “Can’t get you out of my head” and New Order’s “Blue monday” - most of the time they are not endorsed by the artists (or the label’s lawyers), whereas astronomical data mashups are encouraged and have become routine practice. Once the principal investigators have mined the data, datasets are opened up.

Having said that, I still find the mashup music of the early 00’s - exemplified above by Dsico’s fine blend of Missy Elliott (2001) and Joy Division (1980) - something of a metaphor for what at times goes on in science. Sometimes datasets - songs - recorded for one purpose are merged with other datasets, recorded under other circumstances, to produce a work that was not thought of by the makers of the original datasets, something that builds something new and strong upon two rather disjointed things. Trivial, I know, but still I find it an interesting thing to consider; astronomers’ daily practice is sometimes about doing such mashups. Astronomy has developed a culture of making whole datasets publically available, and one part of astronomical practice is putting such stuff together.

This is not something new, something that goes on in our e-science epoch using the web as infrastructure. Take the Lund Observatory Milky Way Panorama (1955), for example. It was produced from photographs - the Franklin-Adams Atlas (1914), for example -, data for the positions and magnitudes of 7000 stars, photometric measurements of the Milky Way, data for converting RA and declination to galactic coordinates &c.


From Photographic Photometry of the Southern Milky Way (Amsterdam, 1949) by Pannekoek, one of the datasets used by Knut Lundmark and his group.

Putting these diverse datasets together to the Lund Observatory Panorama was a non-trivial exercise; an artist worked on the task for two years, painstakingly painting the Milky way, with a basis in the datasets, under the guidance of Knut Lundmark, whose aesthetic judgment seemed to have played an important role in the genesis of the picture.

Mashups of standard datasets are, as I mentioned, encouraged. There are also tools available, facilitating the mashups. Take SkyView, the frontend to many sky survey data from across the spectrum. At the query page you choose between datasets, from gamma rays to radio and can mix them up; you can choose different projections, plot coordinate grids &c.

Here is a mashup of M31 I just produced. Red and green are IRAS data, blue is the blue plate from the Palomar sky survey. Combining data from a photographic sky survey produced on Mount Palomar between 1948 and 1958 with the large Schmidt telescope there and originally recorded on photographic glass plates, 14 inches square (and in our age digitized with high-precision scanners) with data from a multi-national infrared telescope project, observing from a satellite in orbit around the earth in 1983, was just a matter of a few clicks.

Using Zotero, pt 5.

Just a small note, this time, on customizing Zotero’s Word plugin: I have wanted keyboard shortcuts to Zotero, for example for insert note, instead of clicking on a button. Found this on the Zotero forum:

# 1 is indeed a word processor issue. In Word, choose Tools –> Customize –> Keyboard, pick “Macros” from the Categories list, pick (e.g.) “ZoteroInsertCitation” from the Macros list. Write your shortcut key sequence of choice (e.g. F4) where it says “Press new shortcut key”, –> Assign –> Close.

Works like a charm. (I’m on Word 2004, Mac OS X 10.5.4.)

Also, these last days I’ve been working on one of my papers; it’s still early in the process, so lots of pdf’s are downloaded and references collected, and Zotero’s automatic way of getting reference data from, for example, ADS, which I’ve been using a lot, is really a boon. Much more handy than having Endnote to connect to some other database than ADS just to get this stuff. It’s becoming second nature, now, after a while; whenever I see some paper that is interesting, I look for the symbol in the address field in Firefox and just click. Really handy.

Using Zotero, pt 4.

Now, I’ve taken a step back from Zotero Synch Preview 1.5 used in connection with Word 2008 (on Mac) to 1.0.9 used in connection with Word 2004.

The reason is the instability (it is, after all, an alpha version) of the Word plugin; several times, it has made Word hang, most often when inserting a bibliography.

Backtracking to the 1.0.9 version was easy:

  • I exported my library to a file on my desktop
  • uninstalled Zotero from Firefox
  • removed the Zotero folder from /Library/Application Support/Firefox/Profiles//zotero
  • installed the 1.0.9 version
  • imported the library from the desktop

When starting Word 2004, everything seems to be working fine.

Sometimes it is better not to live the bleeding-edge early adopter life of using software in beta and alpha state!

In the process, I got good support from the Zotero Forum, which I appreciate (here and here).

Using Zotero, pt 3.

In this, the third field-note of my trial to use Zotero for my daily research, a problem is encountered and various ways of solving it are discussed. This is in contrast with previous posts about Zotero - migrating from Endnote was not a big problem.

My experience of using the combination Endnote-Microsoft Word-Mac OSX these last years is that it could lead to hassles in that upgrading one of them risked breaking the compatibility. This same problem is now on Zotero.

I have chosen to use new versions of Zotero, those beta versions that are declared available every once in a while when starting Firefox. Therein lies my present problem, since the latest version of Zotero synch preview 1.5 breaks connection with Word 2004; the Word plugin (version 1.03b) does not work, and there’s not currently a Word plugin supporting Mac Word 2004 available (although one is planned). There are only two plugins available as of today, both are alpha versions (sounds a bit risky, doesn’t it?): one for Word 2008, one for Open office/NeoOffice.

The options:

Going back to Endnote (perhaps temporarily?) is one, albeit one I’d wish I could avoid - the features of Zotero gives it an edge over Endnote, I think. Still, the combination Word2004 + Endnote 9 works and I could stay there until the Zotero 1.5 final version is available with a Word 2004 plugin.

Another is trying to base my work on NeoOffice. It would give a nice warm open-source software gut feeling (but I’m definitely not an OSS fundamentalist), though it also could lead to some future problems when exchanging files with colleagues who work with the latest version of Office. And I’ve been on Word since, well, since everything started, really, the only alternative to Word I’ve been using (not counting what I did before PC and Mac, on Amiga and Compucorp 625 Mark II, but that is a very long time ago) is Writeroom, which I still use every now and then.

And a third is, of course, upgrading to Word 2008. This is something I ought to have done earlier, but Word 2004 (PowerPC) has worked remarkably well on my Intel mac, the Rosetta architecture taking care of things in a transparent way.

I still have not explored all these in sufficient detail, but I will post further reports.

Activism against shutdown: The case of DDO

David Dunlap Observatory was inaugurated in 1935 and its 1.8 meter Grupp Parsons reflector was large for its times. The observatory figured prominently in fields such as stellar radial velocities during the mid-20th century (J.B. Hearnshaw, The analysis of starlight: One hundred and fifty years of astronomical spectroscopy (Cambridge University Press, 1986, 182ff) but its telescope became increasingly seen as outdated and the location as not suitable because of light pollution.

When plans for the closure of the observatory became public, an online petition was started that eventually got 2866 signatures. Arguments and comments were that the observatory played a role for education and inspiring people in science (”Must every child be brought up to be a hockey player”); local and national heritage and cultural history; greed trumping academic values; environmental issues; research policy, in that the closure showed how little science mattered in Canada.

Now, the petition did not succeed, David Dunlap Observatory was sold, generating $70 million for the university, but such organized “resistance”, as it were, shows what can happen when a scientific installation has generated enough public interest in the surrounding community. Some sciences are more likely to generate such support than others I guess. Astronomy, zoology/natural history come to mind, but who would organize public protests against the shutdown of an outdated protein lab?

Shutting down science

The process of dismantling scientific facilities is an area that I find increasingly interesting. Historians of science are prone to look at the constructive phases: who built what research facilities and when, how where difficulties ovecome in actually getting the complicated scientific instruments working. I am, of course, no exception; in my PhD dissertation, I studied how astronomy in Sweden changed as photography, spectroscopy, and similar technologies were introduced, and in my latest publication - just finished proofreading a book chapter on Swedish solar science in the post-war period - I study Yngve Öhman, whose work very much was about inventing and introducing new stuff; early in his career, together with Bernard Lyot, he invented the so-called Lyot-Öhman filter, used at every solar observatory, and then a steady stream of instruments and new things and observing stations and methods flowed from his fertile imagination. A cynic could construe it as a lingering whigism in the field of history of science - but that is perhaps a bit harsh - or it could be seen as a natural outcome of the historian’s interest in change over time; anyway: we tend to study new things.

It’s a bit like in the history of technology, that often studies new technologies rather than looking at mature and even old technologies, a critique discussed in The shock of the old by David Edgerton and Svante Lindqvist, “Changes in the Technological Landscape: The Temporal Dimension in the Growth and Decline of Large Technological Systems” in Granstrand ed., Economics of Technology (Amsterdam, 1994).

So, I have the idea of actually doing some work on dismantling science (as opposed to just being interested in the phenomenon in a general and vague way); what will come out of it I don’t know: yet another entry in my list of unrealized ideas, materialized by yet another box of xerox copies of source materials and printouts of unfinished, unpolished and unpublished manuscrips on my shelf; a conference presentation; a published paper; a large-ish research project or even a book. We will see. But what I do know is that I will post fieldnotes along the way here on Imaginary magnitude. Howard S. Becker writes about how he talked “to anyone who would listen” about what was about to become his next paper, long before he even began writing (Writing for social scientists: How to start and finish your thesis, book, or article (Chicago, 1986), 100f). Perhaps blogging can work in the same way. I don’t know, but perhaps after a number of blog posts the threshold to actually writing something and sending it off to an editor somewhere is overcome.

So expect every once in a while to find links and snippets of text here. And, oh, I have a slightly grandiose suggestion for a name of this endeavour: “Shutting down science: the politics and practice of dismantling research infrastructure”.

Let’s start with today’s issue of Nature, where it is reported that European astronomy is working on a plan to prioritize among astronomy projects; the Astronet infrastructure roadmap is compared, by Nature, with the long-established surveys of US astronomy made every decade.

Astronet’s priority, the European Extremely Large Telescope - if you’re not following astronomy closely, let me remind you that there is a Very Large Telescope in actual existence and an Overwhelmingly Large Telescope in the project design stage; astronomers are currently running out of superlatives to describe their projects - will cost €1 billion.

So shutting down some existing facilities could free up resources that could be pooled to the 40 metre giant that is Astronet’s goal. Therefore the organization “is already reviewing the roles of some smaller, two- to four-metre European telescopes in an attempt to eliminate research overlap”, Nature observes and notes that in the future similar reviews of telescopes in the eight-metre class could come.

So one large telescope, correction: an extremely large telescope, is pitted against smaller telescopes, cutting edge during the 1980’s but nowadays left behind in a race to bigger telescopes where Europe risks being outrun by the US.

What the Nature piece does not dwell on is who might speak for the smaller telescopes. There ought to be some scientific reasons for the continued operation of at least a number of telescopes in the two to four metre class. With a very big telescope, one can observe things impossible to see with smaller telescopes but use of such giant telescopes will be oversubscribed; typically observers on it will get small slots of telescope time. This type of instrument is not geared to doing time-consuming survey projects. Some types of objects that need to be monitored for longer periods of time can be studied by such smaller telescopes that are proposed for shutdown.

I am curious if the harmony in the European astronomical community implied in the Nature article is real, or if there are groups of the community that rather would keep a larger group of telescopes working. I really don’t know.
