    Notes: [Auszug] The following preliminary optical examinations have been made. Chrysene crystallised in monoclinic plates showing the forms (001), (110) and (100). There is a marked tendency to twin on the c face. (010) is the optic axial plane with γ making 10° to the c axis in the obtuse angle. The ...

    Notes: [Auszug] AN investigation on the relation between the crystal structure and optical properties of organic crystals has revealed further cases of ‘rotating’ and ‘fixed’ molecule forms in aliphatic compounds. A hexagonal rotating form has been observed between 16° and 24° C. in dodecyl alcohol ...

    Notes: [Auszug] DR. HULL'S analysis of the production and stability of simple organic molecules in a lifeless Earth is a valuable contribution to the discussion on biopoesis. By introducing a quantitative discussion he has effectively narrowed down the range of possibilities and thus presented a much more definite ...

    Notes: [Auszug] SINCE the work referred to in my communication to Nature early in 19591, it has been possible to approach the problem in a more quantitative way by the use of computers and geometrical models. Following up the concept of a liquid as an essentially irregular assembly, I have been able to realize a ...

    Notes: [Auszug] SCIENCE teaching and research have been fully restored in Hungary. The damage caused in the fighting last autumn was, fortunately, on the whole slight. The only serious loss was the almost complete destruction of the natural history collections in the burnt-out National Museum [see following ...

    Notes: [Auszug] The crystals showed the forms (001) and (110), but in addition every crystal showed one, and only one, form of the plane (100). In other words, one acute corner of every diamond-shaped crystal was truncated. This seemed to me a strong indication that there was no axis of symmetry and that the space ...

    Notes: [Auszug] The scientific value of the symposium lay, it seemed to me, in the fact that so many distinguished and active scientists in fields ranging from astrophysics to genetics, with a strong central weighting in biochemistry, had come together to discuss a subject of such wide scope and importance as the ...

    Notes: [Auszug] IT has been known for many years that, in the systems of hydroxides of some tervalent metals, notably iron and aluminium, there exist two series of crystalline structures, a and y, the first of which on heating gives rise to hexagonal oxides (haematite, Fe2O3; corundum, A12O3) and the second to ...

    Notes: [Auszug] It has occurred to me that, in just such complex crystals, use can be made of the physico-chemically reasonable assumption that the molecule occupies a large portion of the cell-up to two-thirds-in proteins, the rest being water. Very high or low concentrations of scattering material are unlikely ...

    Notes: [Auszug] FORTY years ago, on June 8, 1912, the first account of diffraction experiments of X-rays by crystals, by Friedrich, Knipping and von Laue, was published in the Sitzungsberichte der Bayerischen Akademie der Wissenschaften. This event, among the most important discoveries of twentieth-century ...
