1. The Sun and Moon, when they are in or near the horizon, appear to the naked eye of the generality of persons, so very large in comparison with their apparent magnitudes, when they are in the zenith, or somewhat elevated, that several learned men have been led to enquire into the cause of this phænomenon, and, after endeavouring to find certain reasons, founded on the principles of physics, they have at last pronounced this phænomenon as a mere optical illusion.

Three-dimensional (3D) microstructure visualization on the electron microscope requires that the sample be tilted to different positions to collect a series of projections. This tilting should be performed rapidly for on-line stereo viewing and precisely for off-line tomographic reconstruction. Usually a projection series is collected using mechanical stage tilt alone. The stereo pairs must be viewed off-line and the 60 to 120 tomographic projections must be aligned with fiduciary markers or digital correlation methods. The delay in viewing stereo pairs and the alignment problems in tomographic reconstruction could be eliminated or improved by tilting the beam if such tilt could be accomplished without image translation.A microscope capable of beam tilt with simultaneous image shift to eliminate tilt-induced translation has been investigated for 3D imaging of thick (1 μm) biologic specimens. By tilting the beam above and through the specimen and bringing it back below the specimen, a brightfield image with a projection angle corresponding to the beam tilt angle can be recorded (Fig. 1a).

Radiomics is a science that investigates a large number of features from medical images using data-characterisation algorithms, with the aim to analyse disease characteristics that are indistinguishable to the naked eye. Radiogenomics attempts to establish and examine the relationship between tumour genomic characteristics and their radiologic appearance. Although there is certainly a lot to learn from these relationships, one could ask the question: what is the practical significance of radiogenomic discoveries? This increasing interest in such applications inevitably raises numerous legal and ethical questions. In an environment such as the technology field, which changes quickly and unpredictably, regulations need to be timely in order to be relevant.  In this paper, issues that must be solved to make the future applications of this innovative technology safe and useful are analysed.

The Swiss geologist and mineralogist Louis-Albert Necker belonged to a family rich in scientific celebrities. Though a professor at the Académie de Genève for 25 years and author of numerous publications, he is mainly remembered today for his description of the “Necker cube” optical illusion and for leaving Geneva to spend the last 20 years of his life in Portree on the Isle of Skye. As a first step towards assessing Necker's contribution to science, a full list of his publications is presented, with comments about their citation in previous bibliographies and about published translations and abridgements. Information about the surviving specimens from his scientific collections, most of which are in the Muséum d'histoire naturelle de Genève, is also presented.
