Recall from the 17 August 2013 post that Luis Bettencourt, David Kaiser, Jasleen Kaur, Carlos Castillo-Chavez, and David Wojick had constructed and tested a model of emergence, and the results suggested that for an emerging field, recruitment of new participants is critical.

When recruiting, there are two audiences one may have in mind.

  • Of course, there are students. Students are energetic, ambitious, and have yet to develop that conservatism that keeps middle class academics in their own fields.
  • There are also colleagues. Colleagues usually do not change fields unless impelled to do so (by necessity or by wanderlust). Colleagues know how the game is played, and they bring expertise.

These are two different audiences. I don’t know how much is known about recruitment of students versus colleagues (perhaps very little, as “emerging fields” as a branch of the sociology of science is itself an emerging field), so all I can do is engage in armchair theorizing. The advantages and disadvantages of joining an emerging field can be assessed differently by students and researchers.

  • A new field is an opportunity. Economists and ecologists have long observed that when individuals find a new environment they can exploit, they can more readily succeed than they would in established terrain. In a new field, there is less competition, there are basic and tractable problems to be solved – and considerable rewards for doing so.
  • A new field is a gamble. Most new businesses fail, most revolutions fail, and probably most new academic fields implode; we remember the successes while the failures are quietly forgotten and rarely make it into the history books. Some do succeed, but fail to deliver on their promises. Even successful ventures may not produce timely success, and the original revolutionaries may not live to see the success of their revolution.

Let’s consider two issues: attraction and access.

Mathematical crystallography faces the same problem that small-town boosters have: how to attract new enterprise. We are all familiar with Chamber of Commerce boosters (the old-fashioned non-ideological kind) who appeared in the business section of the newspaper, talking up the potential of the town. That’s us. So how do we attract enterprise?

It pays to advertise, or so the poem goes. In academia, one can advertise with accessible, semi-popular works. The power of advertising may be over-rated: in assessing the impact of Richard Feynman’s 1959 speech, There’s Plenty of Room at the Bottom in inspiring nanoscience, Chris Toumey found that while many people later remembered Feynman’s article being discussed, there was little documentable evidence of impact prior to the 1980s.

Still, books like Herman Weyl’s Symmetry, Marjorie Senechal and George Fleck’s Shaping Space, and John Conway, Heidi Burgiel and Chaim Goodman-Strauss’s Symmetries of Things may be useful in attracting students to the field.

Papers might also be useful advertising, although the ones that come to mind look more like materials for recruiting colleagues. For example, in 2003, Omar Yaghi et al published a manifesto, Reticular synthesis and the design of new materials, advocating the development of a design process to facilitate the synthesis of novel crystals. On the other hand, in 2008, Massimo Nespolo published a manifesto, Does mathematical crystallography still have a role in the XXI century? which introduced readers to some of the active research areas. And I have just published an article, Prospects for mathematical crystallography, allied to postings in this website.

One possible selling point is that mathematical crystallography is an interdisciplinary field. Unfortunately, this could be a liability. Interdisciplinary fields have been all the rage for some time, but institutional support tends to be a bit thin. In 1995, the National Research Council issued a report on Mathematical Challenges from Theoretical / Computational Chemistry, which addressed institutional obstacles to recruiting for a closely related interdisciplinary field:

  • For faculty, the institutional support and reward structures are designed for within-disciplinary efforts. For example, faculty are evaluated by departments, which often focus on their own disciplines. In addition (though the report did not go very much into this), internal funding is often made available through departments, and credit for external funding is usually assigned to departments.
  • For students, the curriculum is often determined by departments, usually independently of each other. A student in one department could face a long sequence of prerequisites before being prepared to take a relevant course in another department.

The NRC did not mention another problem: external funding agencies like their grant proposals to go into the correct pigeonhole, which is a problem for interdisciplinary programs. So by all means, talk up the interdisciplinary aspects of mathematical crystallography. But we may have to support some institutional reform.

This brings us to a major obstacle: access. Chemists who want to join need to learn physics and mathematics, physicists who want to join have to learn chemistry and mathematics, and mathematicians who want to join need to learn chemistry and physics. I am most familiar with problems learning mathematics, so let’s look at those.

In 1992, Mattel’s Barbie doll said that Math class is tough. Mattel got in trouble with the American Association of University Women because Barbie’s audience was little girls, but there is a feeling that mathematics is an unusually difficult subject. There are a number of theories as to why.

There are even a few people who claim that math is not hard, or at least shouldn’t be. But considering that mathematics has a reputation that chemistry and even physics does not, participants in a mathematical field need to think about how to make their field accessible to novices.

Meetings (like the upcoming IUCr 2014 meeting; see the previous entry for details) are invigorating and fun and provide opportunities to meet and recruit people, but the work of learning a new field is a more lonely business and it involves a lot of reading. We have a strong interest in having a lot of accessible material. And accessibility is a problem in academia.

Etymological dictionaries tell us that arcane is a descendent of the Latin arcere, to contain or maintain, to keep or ward off, and perhaps to the Greek arkein, to keep off. It is associated with the Latin arcana, or mysterious secrets. These are all members of the family of words led by the Latin arca, or ark, as in Noah’s Ark and the Ark of the Covenant.

As a new word, arcane bubbled up in the Sixteenth century, in the midst of the explosion of books created by Gutenberg’s press. Books on just about everything suddenly appeared, and they sold. Just as the Internet not only made everything available to everyone, and made a virtue of universal access, so the Gutenberg revolution made all knowledge available to any plowman able to afford a book.

But some works seemed to remain out of reach, hence the notion of arcane works. Perhaps the printing press was partially responsible for the Plato boom that inspired Renaissance scientists: Plato was a natural novelist (see, e.g., his great literary invention, Atlantis). Perhaps the printing press was partially responsible for Aristotle’s poor reputation in that era: the Complete Works are a jumble of often unintelligible notes and fragments of dubious provenance. And Aristotle was hardly unique. As Great Works became available to the Common Man, common men found many of them inaccessible.

Communication theorists tell us that arcana can serve a purpose. I don’t mean unintentional arcana, like a bunch of moldy papers somehow associated by a major philosopher. I mean (often unconsciously) intentional arcana, like books by German metaphysicians we could name. Consider this grumpy passage by the greatest of them all, Immanuel Kant. In his Prolegomena to Any Future Metaphysics, a sort of Kant-for-Dummies-by-Kant-Himself, Kant writes that his major work, the Critique of Pure Reason

… will be misjudged because it is misunderstood, and misunderstood because men choose to skim through the book, and not to think through it – a disagreeable task, because the work is dry, obscure, opposed to all ordinary notions, and moreover long-winded.

Some communication theorists might detect a little pride in that sentence. Still,

I confess, however, I did not expect, to hear from philosophers complaints of want of popularity, entertainment, and facility, when the existence of a highly prized and indispensable cognition is at stake, which cannot be established otherwise, than by the strictest rules of methodic precision.

There are two interesting points about this passage. First, Kant was irritated that philosophers, much less educated laymen, were unwilling to invest the vast amount of time and energy required to read the Critique. But second, he did write the Prolegomena after all, and that was consistent with what some commentators have claimed about Kant: he had an agenda, and that agenda required readers and students. Kant started his introduction to the Prolegomena with the words, “These Prolegomena are destined for the use, not of pupils, but of future teachers …”; perhaps concerned by the criticism of his colleagues, he wanted to make sure that teachers, at least, understood what he was trying to say.

Academics aren’t the only ones who make the difficulty of the material into a gatekeeper, but that is one of our bad habits. Especially when our goal is accessibility. It all boils down to who the audience is. New Yorker archivist Joshua Rothman compared journalists, whose text is relatively undemanding because it is intended for a mass audience, to academics.

In academia, by contrast, all the forces are pushing things the other way, toward insularity. As in journalism, good jobs are scarce—but, unlike in journalism, professors are their own audience. This means that, since the liberal-arts job market peaked, in the mid-seventies, the audience for academic work has been shrinking. Increasingly, to build a successful academic career you must serially impress very small groups of people (departmental colleagues, journal and book editors, tenure committees). Often, an academic writer is trying to fill a niche. Now, the niches are getting smaller. Academics may write for large audiences on their blogs or as journalists. But when it comes to their academic writing, and to the research that underpins it—to the main activities, in other words, of academic life—they have no choice but to aim for very small targets. Writing a first book, you may have in mind particular professors on a tenure committee; miss that mark and you may not have a job. Academics know which audiences—and, sometimes, which audience members—matter.

But mathematical crystallographers are not trying to fill a niche. We are trying to get people involved (or if you prefer, we are trying to create an array of niches). That means that we should be writing papers and books for as wide an audience as possible. So here are some “best practices” we probably should engage in:

  • Papers should be self-contained. In an interdisciplinary field, one’s readers may be unfamiliar with some jargon and some concepts. It may be useful to define them in the paper if that does not take up too much space. Of course, sometimes that would be distracting, so another thing one needs is:
  • Papers should have primary references. Where does the novice reader go to find out what actions, entropy, and carboxyl groups are? It takes very little space to give a citation to a general reference known to be accessible.

It may be a good idea to imagine a graduate student when writing a paper.

The 23rd Congress and General Assembly of the IUCr this August

 Miscellany  Comments Off on The 23rd Congress and General Assembly of the IUCr this August
Jun 012014

Every three years, the International Union of Crystallography holds a Congress and General Assembly. The first was in 1948 at Harvard University in Cambridge, Massachusetts, and the 23rd will be held this summer from August 5 to August 12 in Montreal, Canada.

The entire meeting looks rather large – at the 2011 meeting in Madrid, there were 2,655 “scientific participants” from 73 countries, resulting in 490 oral presentations and 1,550 posters – and this meeting will probably be comparable.

  • Registration opens on August 4.
  • The workshops are on August 5, and the Ewald Prize will be awarded to Aloysio Janner and Ted Janssen for their work on aperiodic crystals.
  • The keynote and plenary speeches, microsymposia, software fayres, poster sessions, and various commissions will be held from August 6 to August 12.
  • The Gjønnes Medal in Electron Crystallography will be awarded to John Steeds and Michiyoshi Tanaka on August 12.

Here are some events that may be of interest to the mathematically inclined:

  • As of May 31, there are four plenary lectures listed.
  • As of May 31, I counted 31 keynote speeches, not counting the two Gøonnes Prize lectures. A few heads-up for the mathematically inclined or the crystal engineer:
    • Crystal Engineering and Applications of Functional Metal-Organic Frameworks by Xiao-Ming Chen on August 7.
    • Mathematical Crystallography in the 21st Century by Marjorie Senechal on August 8.
  • Workshops consist of sessions of extended presentations by experts, and cost $ 25 to $ 60 … and space is limited, so make reservations asap. They are all being held on Tuesday, August 5. These seem to be largely on software.
  • There are several ancillary “commission meetings” during the conference, including an Open (i.e., everybody is invited) Commission Meeting on Mathematical and Theoretical Crystallography, which is scheduled to meet on August 11 during lunchtime – 12:15 – 13:45 on the fifth floor in room 441. Come and bring a colleague – or even better, a student!
  • Recent developments are presented in 112 microsymposia and in poster sessions. Here are some microsymposia whose descriptions suggest substantial mathematical content or opportunities.
    • 2. Recent Advances in Quasicrystal Research, organized by An Pang Tsai and Janusz Wolny, on August 6.
    • 31. In-situ XRD: Parametric and Symmetry Constrained Refinement, organized by Robert Dinnebier and John Evans, on August 7.
    • 33. Symmetry Constraints in Magnetic Structure Determination: Experiment and Theory, organized by Branton Campbell and Mois Ilia Aroyo, on August 8.
    • 34. Crystals and Beyond, organized by S. I. Ben-Abraham and Jeong-Yup Lee, on August 8.
    • 62. Symmetry and Isomorphism in Material Design and Crystal Growth, organized by Tatyana Bekker and Antoni Dabkowski, on August 9.
    • 72. Methods, Algorithms and Software for Powder Diffraction, organized by Ryoko Oishi-Tomiyasu and Jon Wright, on August 10.
    • 95. Symmetry and its Generalisations in Science and Art, organized by M.A. Louise de la Penas and Emil Makovicky, on August 11.
    • 96. New Computational Approaches to Structure Solution and Refinement, organized by Richard Cooper and Lukáš Palatinus, on August 11.
    • 104. Crystal Structure Prediction and Materials Design, organized by Roman Martonak and Tian Cui, on August 12.
    • 112. New Approaches to Crystal Structure Prediction, organized by Graeme Day, on August 12.

    Of course, in addition to the microsymposia, there will be approximately five million posters, including mine. Drop by and browse.

  • There will also be a Software Fayre where software developers can demonstrate their software. While mathematical crystallography may influence crystallography in developing theory, it seems likely that the most impact will be in software.

About Montreal…

Montreal is an island in the St. Lawrence River with a population of about two million people. It was inhabited as early as 4,000 years ago, but during the Sixteenth century, all the people disappeared (!). The French started settling the place in the Seventeenth century, but it was surrendered to the British in 1760. It lies in the province of Quebec, and is now the second largest city in Canada.

Major academies in Montreal include Concordia University, Université Laval, McGill University, the Université de Montréal (including its affiliate, the École Polytechnique de Montréal), the Université du Québec à Montréal (the Ecole de technologie superieure) is affiliated with the university), and the Université de Sherbrooke.

The deadline for reserving accommodations is “[u]ntil blocks are sold out or June 25, 2014, whichever comes first,” and since this is a tourist season, blocks may not last until June 25 (and affordable airplane tickets may be difficult to find).

Summers are, according to Wikipedia, hot and humid, with temperatures ranging from 63 F to 77 F (17 C to 25 C), with mean temperature 70 F (21 C), 4 inches (100 mm) of rain a month, and relative humidity of 79 %. In general, sunny with occasional storms. Despite last year’s story on Montreal in July, High heat and humidity warnings bring serious health threat, to a Florida resident like me it sounds comparatively pleasant.

For future reference …

The 24th Congress and General Assembly will be held in 2017 in Hyderabad, India, capitol of Andhra Pradesh, with a population of nearly eight million people, and home to several academic institutions, including the Birla Institute of Technology and Science, Pilani – Hyderabad, the English and Foreign Languages University, the University of Hyderabad, the Indian Institute of Technology Hyderabad, the Jawaharlal Nehru Technological University of Hyderabad, and Osmania University.
