President's Column Winter 2006 The Future of Education in Crystallography solving of a crystal structure without fully appreciating the For quite some time now I have scientific principles behind what one is doing. This is true in been concerned about the both small-molecule and macromolecular crystallography, and I future of university courses in suspect that it is also true for other related fields such as powder crystallography, especially from diffraction. the point of view of a “small- However, it is eduction in the fundamentals of crystallography molecule” crystallographer that I’m worried about.

There is no easy solution to For the past two or three this problem. The IUCr and other institutions (including many decades it has become synchrotron and neutron diffraction facilities as well as Cold increasingly evident that Spring Harbor) help out immensely by having summer schools and upon the retirement of "hands on"workshops. The ACA has been trying to address this structural chemists like issue with summer courses covering small molecules (organized myself, with research programs by Bryan Craven and Charles Lake) and macromolecules having their main thrust linked (originally organized by B. C. Wang and his group and currently to crystallographic structural being run by Andy Howard) and with workshop such as the one analysis, chemistry departments in on “Crystallographic Educational Policies for the Physical and universities across the country are not replacing those positions Life Sciences” organized by Katherine Kantardjieff and the ACA with junior tenure-track appointments in the same area.

One has only to look at the rapid growth in depositions to all Bob Bau the structural databases to know that this situation is not unique. Yet, we are producing new generations of scientists who rely on crystallographic equipment and techniques, but have little knowledge of the underlying theory, technology or its limitations. Who will push the state-of-the-art? Who will teach crystallography courses in the future? I used to offer a graduate-level course once every two years, but as the use of single-crystal analysis has become more widespread in the past 10 years or so, I’ve been asked to offer this course on an annual basis. However, as I said earlier, what happens when people like me retire? Many universities now offer x-ray courses taught by professional crystallography staff members, most of whom do a really fine and excellent job. This will of course significantly help “plug the gap”, but this practice is by no means universal. In the macromolecular crystallographic community, with a user base of investigators that is continuing to expand, the situation is just as mixed, ranging all the way from universities that offer crystallography courses on a regular basis, to institutions in which graduate students who use crystallography as a tool simply “pick up” a working knowledge of the technique informally from more A C A senior members of their research groups (typically postdocs), with the research director offering guidance and suggestions when difficult structures appear.

Chernyaev to The National Security Archive Translated by Anna Melyakova Edited by Svetlana Savranskaya http://www.nsarchive.org Translation © The National Security Archive, 2013 The Diary of Anatoly S. Chernyaev, 1973 http://www.nsarchive.org January 6, 1973 Even though it’s Saturday, I spent the whole day at work. We’re preparing yet another report on the International Communist Movement [ICM] for Ponomarev. The only satisfaction I get out of it is seeing how much better I can do the work than the “guys” (consultants), and naturally, they willingly submit to my skill. But you can’t respect a person who hasn’t learned anything after ten years on the job. We’ve got a circus going on with the dual management of the Department by Kuskov and Zagladin. Kuskov is tongue-tied and nonsensical, which is probably a reflection of his dulled intellect and tired brain that was subject to too much alcohol in its day. Plus, Kuskov did not have proper training or develop a good work ethic when he was young. Zagladin is not exactly using him because of this, but he finds his helplessness annoying, because it steals time from his subordinates, not to mention the incomprehensible tasks he gives them. I am reading Bykovsky. January 8, 1973 There is a flu epidemic in Moscow, they say that 70,000 people get sick every day (citing statistics from the city committee). It’s probably a lie. But there are many sick people around. The day before yesterday I met with a delegation from the Austrian Communist Party.

  • Crystal Vision Dorothy Hodgkin & the Nobel Prize “Few Were Her Equal in Generosity of Spirit, Breadth of Mind, Cultivated Humaneness, Or Gift for Giving
    Crystal Vision Dorothy Hodgkin & the Nobel Prize “Few were her equal in generosity of spirit, breadth of mind, cultivated humaneness, or gift for giving. She should be remembered not only for a lifetime’s succession of brilliantly achieved structures. While those who knew her, experienced her quiet and modest and extremely powerful influence, learned from her more than the positioning of atoms in the three-dimensional molecule, she will be remembered not only with respect, and reverence, and gratitude, but more than anything else, with love. Let that be her lasting memorial.” Anne Sayre, in the Autumn 1995 Newsletter of the American Crystallographic Association Cover image © Emilio Segre Visual Archives/American Institute of Physics/Science Photo Library Letter from the Principal Dr Alice Prochaska, Somerville College Many remarkable woman scientists have passed through Somerville, but few rival Dorothy Hodgkin, whose path-breaking work in crystallography showed a mind not only attuned to high science but one also able to envision a crystal structure from the pattern made by its X-ray diffraction. Her ability to ‘see’ molecules such as cholesterol, penicillin, vitamin B and insulin transformed her field. 2014 sees the fiftieth anniversary of Professor Hodgkin’s Nobel prize. It is also the International Year of Crystallography, marking the 100th anniversary of Max von Laue’s Nobel Prize for Physics, awarded for his discovery that X-rays could be diffracted by crystals. That discovery underpinned Dorothy Hodgkin’s work. We are proud that Somerville supported her at a time when there was widespread opposition to married women pursuing academic careers.

  • Robert Burns Woodward
    The Life and Achievements of Robert Burns Woodward Long Literature Seminar July 13, 2009 Erika A. Crane “The structure known, but not yet accessible by synthesis, is to the chemist what the unclimbed mountain, the uncharted sea, the untilled field, the unreached planet, are to other men. The achievement of the objective in itself cannot but thrill all chemists, who even before they know the details of the journey can apprehend from their own experience the joys and elations, the disappointments and false hopes, the obstacles overcome, the frustrations subdued, which they experienced who traversed a road to the goal. The unique challenge which chemical synthesis provides for the creative imagination and the skilled hand ensures that it will endure as long as men write books, paint pictures, and fashion things which are beautiful, or practical, or both.” “Art and Science in the Synthesis of Organic Compounds: Retrospect and Prospect,” in Pointers and Pathways in Research (Bombay:CIBA of India, 1963).

  • JOHN DESMOND BERNAL – the SAGE by William Reville, University College, Cork
    JOHN DESMOND BERNAL – THE SAGE By William Reville, University College, Cork. I remember excitedly buying a boxed set of 4 books, Science in History by John D. Bernal (Pelican, 1965), when I was an undergraduate. At the time I was an amateur Marxist and Bernal’s work was an encyclopaedic analysis of science and society from a Marxist point of view. I was delighted to learn that Bernal was an Irishman who had spent a brilliant career at the leading edge of UK science, making many notable contributions. John Desmond Bernal was born in Nenagh, Co. Tipperary in 1901. The Bernals were originally Sephardic Jews who came to Ireland in 1840 from Spain via Amsterdam and London. They converted to Catholicism and John was Jesuit-educated. John enthusiastically supported the Easter Rising and, as a boy, he organised a Society for Perpetual Adoration. He moved away from religion as an adult, becoming an atheist. Bernal showed precocious talent right from the start. At the age of two he was taken by his American mother to see his grandmother in California and he amazed passengers on the steamship by talking in both English and French. In later life at Cambridge his fellow students nicknamed him ‘Sage’ because of his great knowledge. Bernal started as a science undergraduate at Cambridge in 1919 where his studies included mineralogy and the mathematics of symmetry. He gained a research position in 1923 at the Royal Institution in London with William Henry Bragg the eminent crystallographer (one who studies crystalline structures using X-rays). He returned to Cambridge in 1927 as the first lecturer in structural crystallography, fully convinced of the enormous potential of his chosen field to elucidate the structure of the technological and biological worlds.
