Each set of parallel lattice planes is represented by spots which have a distance of 1/d (d: interplanar spacing) from the origin and which are perpendicular to the reflecting set of lattice plane. The two basic lattice planes (blue lines) of the two-dimensional rectangular lattice shown below are transformed into two sets of spots (blue). The diagonals of the basic lattice (green lines) have a smaller interplanar distance and therefore cause spots that are farther away from the origin than those of the basic lattice. The complete set of all possible reflections of a crystal constitutes its reciprocal lattice. The diffraction event can be described in reciprocal space by the Ewald sphere construction (figure 1 below). A sphere with radius λ is drawn through the origin of the reciprocal lattice. Now, for each reciprocal lattice point that is located on the Ewald sphere of reflection, the Bragg condition is satisfied and diffraction arises.

The mineral Braggite is named after him and his son. http://en.wikipedia.org/wiki/William_Henry_Bragg ________________________________________________________________________ Sir William Lawrence Bragg CH OBE MC FRS (31 March 1890 – 1 July 1971) was an Australian-born British physicist and X-ray crystallographer, discoverer (1912) of the Bragg law of X-ray diffraction, which is basic for the determination of crystal structure. He was joint winner (with his father, Sir William Bragg) of the Nobel Prize for Physics in 1915. http://en.wikipedia.org/wiki/William_Lawrence_Bragg 1 1. x-ray source Fig. Schematic diagram for the generation of x-rays. Metal target (Cu or Mo) is bombarded by accelerating electrons. The power of the system is given by P = I(mA) V(keV), where I is the current of cathode and V is the voltage between the anode and cathode. Typically, we have I = 30 mA and V = 50 kV: P = 1.5 kW. We use two kinds of targets to generate x-rays: Cu and Mo. The wavelength of CuK1, CuK2 and CuK lines are given by K1 1.540562 Å. K 2 = 1.544390 Å, K = 1.392218 Å. The intensity ratio of CuK1 and CuK2 lines is 2:1. The weighed average wavelength K is calculated as 2 K 1 K 2 = 1.54184 Å.

This work, originally published in German language, is transferred into English while the preceding foreword summarizes Hermann’s achievements. Keywords Crystal symmetry · Symmetry groups · Elasticity · Fourth-order tensor · Hermann’s theorem Foreword Introduction The work of Carl Hermann on the representation of explicit invariance requirements on tensor components due to crystal symmetries is undoubtedly a milestone in the theory of anisotropic materials. He published his approach in an article which appeared in Zeitschrift für Kristallographie (German for Journal of Crystallogra- phy,nowZeitschrift für Kristallographie—Crystalline Materials1) in 1934; cf. Hermann [13]. However, this work is not well known since it was published in German language solely. Carl Hermann (1898–1961) was a German physicist whose work focused on crystallography. He studied in Göttingen where he finished in 1923 his dissertation2 under the supervision of Max Born (1882–1970). He then moved to Stuttgart where he became an assistant of Paul Peter Ewald (1888–1985). In Stuttgart, he 1 Journal homepage http://www.degruyter.com/view/j/zkri. 2 The title of this dissertation is On the natural optical activity of some regular crystals (NaClO3 and NaBrO3): A proof of Born’s theory of crystal optics (englisch for Über die natürliche optische Aktivität von einigen regulären Kristallen (NaClO3 und NaBrO3): eine Prüfung der Bornschen Theorie der Kristalloptik) which was later published in Hermann [11].

  • Paul Peter Ewald (January 23, 1888 in Berlin, Germany – August 22, 1985 in Ithaca, New York) Was a U.S
    Paul Peter Ewald (January 23, 1888 in Berlin, Germany – August 22, 1985 in Ithaca, New York) was a U.S. ( German-born) crystallographer and physicist - a pioneer of X-ray diffraction methods. Education Ewald received his early education in the classics at the Gymnasium in Berlin and Potsdam, where he learned to speak Greek, French, and English, in addition to his native language of German. Ewald began his higher education in physics, chemistry, and mathematics at Gonville and Caius College in Cambridge, during the winter of 1905. Then in 1906 and 1907 he continued his formal education at the University of Göttingen, where his interests turned primarily to mathematics. At that time, Göttingen was a world-class center of mathematics under the three “Mandarins” of Göttingen: Felix Klein, David Hilbert, and Hermann Minkowski. While studying at Göttingen, Ewald was taken on by Hilbert as an Ausarbeiter, a paid position as a scribe, i.e., he would take notes in Hilbert’s classes, have the notes approved by Hilbert’s assistant – at that time Ernst Hellinger – and then prepare a clean copy for the Lesezimmer – the mathematics reading room. In 1907, he continued his mathematical studies at the Ludwig Maximilians University of Munich (LMU), under Arnold Sommerfeld at his Institute for Theoretical Physics. He was granted his doctorate in 1912. His doctoral thesis developed the laws of propagation of X-rays in single crystals. After earning his doctorate, he was an assistant to Sommerfeld. During the 1911 Christmas recess and in January 1912, Ewald was finishing the writing of his doctoral thesis.

Crystal comes from the Greek κρύσταλλος (krystallos), that means “ice”, from κρύος (kruos), "icy cold” or “frost” (VIII BC). The Greeks used the word krýstallos with a second meaning that designated "rock crystal", a variety of quartz. –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– On the occasion of the International Year of Crystallography, and of the centennial of the award of Nobel prizes related with the discovery of X-ray diffraction, the Library of Physics and Chemistry (Biblioteca de Física i Química) of the University of Barcelona organized in 2014 an exhibition on the historical evolution and the bibliographic holdings of these two closely related subjects.
