X-Ray Crystallography might seem like an obscure, even unheard of field of research; however structural analysis has played a part in almost every major scientific field since its discovery 100 years ago by William Henry, and William Lawrence Bragg.
In this Friday Evening Discourse at the Royal Institution, Professor Stephen Curry charts the discovery and development of this extraordinary technique, starting with a simple explanation of diffraction, moving through the integral work of the Braggs, and ending with the cutting edge uses that X-Ray Crystallography has found in the modern world.
This film is part of the Crystallography Collection: a series of short films produced by the Ri Channel, with the support of the Science and Technology Facilities Council (STFC), celebrating the 100th anniversary of the discovery of X-Ray Crystallography by the Braggs

Outstanding lecture. Well done Sir! I’m a retired physicist, having spent much of my career mucking about in an X-ray lab doing radiology research. How I wish that I had access to lectures of this quality in my undergraduate days! Hats off too to the Royal Institution for making these wonderful lectures available. I’m very grateful for this continued intellectual stimulation now that I’m away from campus.

Very classic style lecture, well done, graphics were, resolution was very good. I like how the lecturer brought in the history and tied it together with present day thought. Very well delivered, nice pace. Camera though should be on at all times what the person / lecturer is pointing to or referring to, the camera man/production staff seem to forget the audience (the viewing audience) is not physical present so we can't see both the screen and the professor at the same time, but otherwise, thanks for a very professional presentation. Friends from across the lake (US) thanks again.sms

The discussion on X-ray crystallography is amazingly attractive. The discussion enables me in identifying the source of X-rays (electric & magnetic fields), x-ray diffractions, some of the peculiar properties of x-rays, and their applications. I am of course familiar with discussions on X-ray diffraction in Solid state Physics, particularly Bragg's law and Laue Equations. This extended discussion is quite useful and can be further extended to Molecular Biophysics for the analysis of the structure of polymers, Proteins, DNA, and other molecules. Hence, the idea can be a basis for Molecular dynamics simulations in addition to neutron diffraction. Thanks.

A very well spoken presentation indeed. Prof Curry I wish you had taught my physics class when I went to school to be an xray technologist, so many years ago. With all due respect to my teacher, at the time, I did leave there was a complete understanding of the creation of xrays, but feel your presentation would have made it a much easier task for sure. The history aspect used to present this material made it that much more interesting to me. I was aware of your mispronunciation of Roentgen's name but decided to give you a pass on that. :) I hope you will do the same for any misspellings and or poor grammar in this post.

That Watson and Crick didn't share their Nobel Price with Florence Bell is a historical shame. Without her showing them the diffraction pattern, they would never have been able to beat Ulf Lagerkvist in Sweden to the publishing of the structure (little known fact, he was only three months away from print).
@scurryww
@scurryww 8 лет назад
+Eskil Eriksson I think you mean Franklin, rather than Bell, who worked with Astbury in Leeds and recorded some of the first X-ray diffraction patterns of DNA fibres. Intriguingly, Astbury;s later co-worker, Elwyn Beighton took a photograph that was as good as Franklin & Gosling's famous 'photograph 51' but none of the principals involved in working out the structure ever saw it. See www.leeds.ac.uk/heritage/Astbury/Beighton_photo/index.html. By the way, is there anything written about Lagerkvist's work on the DNA structure - that was news to me).
@eskileriksson4457
@eskileriksson4457 8 лет назад
+Stephen Curry First; thank you for a fantastic lecture, and for responding with those links. I do stand corrected. The race to find the structure sure was interesting. I got he story from my father, who studied at Lagerkvist's department in the University of Gothenburg. Ulf Lagerkvist was a brilliant scientist, but the gossip was that he never fully recovered from the near miss. And it didn't exactly help that his father, Pär Lagerkvist, had gotten a Nobel Prize in literature in 51*. So, sadly, I have nothing to offer in the form of written proof. But I'll go ahead and read Lagerkvist's book, DNA Pioneers and their Legacy. Probably to find more holes in this story and my original comment :)
@scurryww
@scurryww 8 лет назад

Will you please take the time to comment on this, to an electron devotee. If in an experimental setup in 'our world', not in the world and dimensions of the atom off course, particles were spread somehow in 3D space, hit with radiation and produced AN IDENTICAL (LAUE) DIFFRACTION PATTERN, AS THE ONE THAT IS CREATED BY A NaCl, for example, CRYSTAL, what would the relationship be, between the known position of these particles and the position (instantaneous ?) of the electrons in the atoms of NaCl that underwent through a regular crystallographic process, if any.?
