What is X-Ray Crystallography?

For millennia, humans have wondered about how the building blocks of the universe fit together. In the 20th century the science of X-ray crystallography revealed our molecular world at a level previously unimaginable, far beyond the limits of the microscope.

Professor Mike Glazer and Science Museum Curator of Contemporary Science Sophie Waring explain how the method works to produce molecular models which have had an immense impact on science and medicine.
