A Century of Crystallography

This poster, from the Science and Technology Facilities Council, celebrates 100 years since two scientists in the UK pioneered a technique for crystallography.

Crystallography uses x-rays to create a diffraction pattern to examine the atomic structure of crystals. The poster explains Bragg’s Law, which allows the calculation of the separation between atoms, when using a known wavelength of x-ray light.

The poster explains the numerous applications of crystallography including materials research, medicine, electronics, and molecular biology, including the discovery of the structure of DNA.

Further information is provided about STFC and the Diamond Light Source, at Harwell, Oxfordshire, in the teachers’ notes. The notes also contain links to other crystallography resources.
