History of crystallography
History of crystallography, a great listen from BBC radio: http://www.bbc.co.uk/programmes/b01p0s9s
"Melvyn Bragg and his guests discuss the history of crystallography,
the study of crystals and their structure. The discovery in the early
20th century that X-rays could be diffracted by a crystal revolutionised
our knowledge of materials. This crystal technology has touched most
people's lives, thanks to the vital role it plays in diverse scientific
disciplines - from physics and chemistry, to molecular biology and
mineralogy. To date, 28 Nobel Prizes have been awarded to scientists
working with X-ray crystallography, an indication of its crucial
importance.
The history of crystallography began with the work of
Johannes Kepler in the 17th century, but perhaps the most crucial leap
in understanding came with the work of the father-and-son team the
Braggs in 1912. They built on the work of the German physicist Max von
Laue who had proved that X-rays are a form of light waves and that it
was possible to scatter these rays using a crystal. The Braggs undertook
seminal experiments which transformed our perception of crystals and
their atomic arrangements, and led to some of the most significant
scientific findings of the last century - such as revealing the
structure of DNA. "
