How is the diffraction pattern obtained in an x-ray experiment such as that shown in Figure 18.5b related to the crystal that caused the diffraction This question was addressed in the early days of x-ray crystallography by Sir Lawrence Bragg of Cambridge University, who showed that diffraction by a crystal can be regarded as the reflection of the primary beam by sets of parallel planes, rather like a set of mirrors, through the unit cells of the crystal (see Figure 18.6b and c). 

The crucial experiments that determined the structures of a number of very simple crystals, beginning with sodium chloride, were done, not by von Laue and his helpers, but by the Braggs, William (1862-1942) and Lawrence (1890-1971), father... 

The structure of sodium chloride determined by the Braggs in 1913 was deeply disturbing to many chemists. In a letter to Nature in 1927, Lawrence Bragg made... 

In 1913, William and Lawrence Bragg, who were father and son, determined how the spacings of layers in crystal structures give different x-ray diffraction patterns. Today, it is possible to observe the diffraction... 

German physicist Max von Laue (1879-1960) and British scientists Sir William Henry Bragg (1862-1942) and his son. Sir William Lawrence Bragg (1890-1971), discover how to use X-ray diffraction to analyze the structure of molecules. 

The Conference was opened on October 24 with reports by Lawrence Bragg and Arthur Compton about the new experimental evidence regarding scattering of X-rays by electrons exhibiting widely different features when firmly bound in crystalline structures of heavy substances and when practically free in atoms of light gases. 

The next Solvay Conference in Physics, the 8th from the beginning, took place in October 1948, that is, 15 years since the previous one. The Scientific Committee was now chaired by Sir Lawrence Bragg. The general theme of the conference was Elementary Particles. 55... 

The 13th Conference on the Structure and Evolution of Galaxies took place in October 1964.105 It was presided over by Robert Oppenheimer, who had succeeded Sir Lawrence Bragg. 

Figure 3.l5d shows the structure of sodium chloride as determined by the X-ray diffraction technique. The study of crystals using X-ray diffraction was pioneered by Sir William Bragg and his son Sir Lawrence Bragg in 1912. X-rays are a form of electromagnetic radiation. They have a much... 

William H. Bragg, 1862-1942, professor of mathematics and physics and his son W. Lawrence Bragg, 1890-1971, professor of physics, received together the Nobel Prize for Physics in 1915.
