Book Description
In the Preface to Early Papers on Diffraction of X-rays by Crystals Volume I (containing Chapters I-V and published in 1969), the history and planning of the complete book were outlined. The publication in two separate and consecutive volumes was merely a matter of management; the compilation of both volumes was done at the same time. There is a distinct difference in subject-matter between both volumes: Volume I contains the fundamentals of the theory, while Volume II treats the practical development of the 'trial' -method and the genesis and first applications of the Fourier method. In the period covered by Early Papers (1912-1935), the trial method leads to the successful conquest of structures with up to a hundred parameters. We conclude the book with Patterson's discovery (1934) of the p2-series as described in his second, more detailed and extended paper of 1935. With this method the apparatus was completed which led to the present undreamt-of successes of the Fourier method in the field of organic chemistry. We have considered the inclusion of Robertson's famous synthesis of the structure of phtalocyanine (1936). However, we decided that its proper place would be at the beginning of a book which, no doubt, will appear one day, describing this later period. Considerations of space caused us to give up the chapter on Texture planned at first.

Book Description
DNA. The double helix; the blueprint of life; and, during the early 1950s, a baffling enigma that could win a Nobel Prize. Everyone knows that James Watson and Francis Crick discovered the double helix. In fact, they clicked into place the last piece of a huge jigsaw puzzle that other researchers had assembled over decades. Researchers like Maurice Wilkins (the 'Third Man of DNA') and Rosalind Franklin, famously demonised by Watson. Not forgetting the 'lost heroes' who fought to prove that DNA is the stuff of genes, only to be airbrushed out of history. In Unravelling the Double Helix, Professor Gareth Williams sets the record straight. He tells the story of DNA in the round, from its discovery in pus-soaked bandages in 1868 to the aftermath of Watson's best-seller The Double Helix a century later. You don't need to be a scientist to enjoy this book. It's a page-turner that unfolds like a detective story, with suspense, false leads and treachery, and a fabulous cast of noble heroes and back-stabbing villains. But beware: some of the science is dreadful, and the heroes and villains may not be the ones you expect.

Book Description
2012 marked the centenary of one of the most significant discoveries of the early twentieth century, the discovery of X-ray diffraction (March 1912, by Laue, Friedrich, and Knipping) and of Bragg's law (November 1912). The discovery of X-ray diffraction confirmed the wave nature of X-rays and the space-lattice hypothesis. It had two major consequences: the analysis of the structure of atoms, and the determination of the atomic structure of materials. This had a momentous impact in chemistry, physics, mineralogy, material science, and biology. This book relates the discovery itself, the early days of X-ray crystallography, and the way the news of the discovery spread round the world. It explains how the first crystal structures were determined, and recounts which were the early applications of X-ray crystallography. It also tells how the concept of space lattice has developed since ancient times, and how our understanding of the nature of light has changed over time. The contributions of the main actors of the story, prior to the discovery, at the time of the discovery and immediately afterwards, are described through their writings and are put into the context of the time, accompanied by brief biographical details.

Book Description
This classic book gives, in extensive tables, the irreducible representations of the crystallographic point groups and space groups. These are useful in studying the eigenvalues and eigenfunctions of a particle or quasi-particle in a crystalline solid. The theory is extended to the corepresentations of the Shubnikov groups.
