Contemplación e interpretación del 'cuadrado mágico'.

El cuadro mágico no puede ser sólo una simple acrobacia. El cuadro mágico ha seducido y retenido la atención. Esto solo puede ser debido a los sentidos y a la imagen misma que representaba. Aparece la cruz y es toda una simbología cuyas únicas letras empleadas son las vocales: a, e, o y las consonantes: n, p, r, t y s y sólo las que componen las dos palabras pater noster. El autor habrá constituido la primera cruz por medio de tenet y habrá apuntalado cada brazo con a y o, lo que le daba ya sobre los lados ato y ata. E cuadro es mucho más simple que los criptogramas simbólicos descifrables por medio del isopsefismo, pero lo que significaba es un enigma.

Strongly nucleophilic RhI centre in square-planar complexes with terdentate (κ3) 2,2′:6′,2′′-terpyridine ligands: crystallographic, electrochemical and density functional theoretical studies

Rh-I-terpyridine complexes have been unambiguously formed for the first time. The 2,21:6',2"-terpyridine (tpy), 4'-chloro-2,2':6',2"-terpyridine (4'-Cl-tpy) and 4'-(tert-butyldimethylsilyl-ortho-carboranyl)-2,2':6',2"-terpyridine (carboranyl-tpy) ligands were used for successful syntheses and characterisation of the corresponding Rh-I complexes with halide coligands, [Rh(X)(4'-Y-terpyridine)] (X = Cl, Y = H, Cl, carboranyl; X = Br, Y = H). All four neutral Rh-tpy complexes are square planar, with Rh-X bonds in the plane of the 4'-Y-terpyridine ligands. Full characterisation of these dark blue, highly air-sensitive compounds was hampered by their poor solubility in various organic solvents. This is mainly due to the formation of pi-stacked aggregates, as evidenced by the crystal structure of [Rh(Cl)(tpy)]; in addition, [Rh(Cl)(carboranyl-tpy)] merely forms discrete dimers. The (bonding) properties of the novel Rh-I-terpyridine complexes have been studied with single-crystal X-ray diffraction, (time-dependent) density functional theoretical (DFT) calculations, far-infrared spectroscopy, electronic absorption spectroscopy and cyclic voltammetry. From DFT calculations, the HOMO of the studied Rh-I-terpyridine complexes involves predominantly the metal centre, while the LUMO resides on the terpyridine ligand. Absorption bands of the studied complexes in the visible region (400-900 nm) can be assigned to MLCT and MLCT/XLCT transitions. The relatively low oxidation potentials of [Rh(X)(tpy)] (X = Cl, Br) point to a high electron density on the metal centre. This makes the Rh-I-terpyridine complexes strongly nucleophilic and (potentially) highly reactive towards various (small) substrate molecules containing carbon-halide bonds.

The science case for an orbital mission to Uranus: Exploring the origins and evolution of ice giant planets

Giant planets helped to shape the conditions we see in the Solar System today and they account for more than 99% of the mass of the Sun’s planetary system. They can be subdivided into the Ice Giants (Uranus and Neptune) and the Gas Giants (Jupiter and Saturn), which differ from each other in a number of fundamental ways. Uranus, in particular is the most challenging to our understanding of planetary formation and evolution, with its large obliquity, low self-luminosity, highly asymmetrical internal field, and puzzling internal structure. Uranus also has a rich planetary system consisting of a system of inner natural satellites and complex ring system, five major natural icy satellites, a system of irregular moons with varied dynamical histories, and a highly asymmetrical magnetosphere. Voyager 2 is the only spacecraft to have explored Uranus, with a flyby in 1986, and no mission is currently planned to this enigmatic system. However, a mission to the uranian system would open a new window on the origin and evolution of the Solar System and would provide crucial information on a wide variety of physicochemical processes in our Solar System. These have clear implications for understanding exoplanetary systems. In this paper we describe the science case for an orbital mission to Uranus with an atmospheric entry probe to sample the composition and atmospheric physics in Uranus’ atmosphere. The characteristics of such an orbiter and a strawman scientific payload are described and we discuss the technical challenges for such a mission. This paper is based on a white paper submitted to the European Space Agency’s call for science themes for its large-class mission programme in 2013.

Art as parodic practice

Perhaps because of the pervasive sampling, remixing, rehashing and promiscuous citational blending in postmodernity, where quote marks dissolve, parody has come to be seen as a somewhat archaic concept, pertaining to cultures more stably codified and hierarchically ordered, rather than subject to the fluctuations of global markets and phantasmagoric projections affecting the flow of investment moneys. Given the anxiogenic nature of postmodernity under its various guises, willed as hypermodernityand metamodernity or supermodernity, the ideologeme ‘parody’ might be seen as nostalgic symptom in the wake of the ‘grand narratives’ (Lyotard 1984 [1979]) – a rehearsed post-apocalyptic nostalgia for a world of neo-feudalism and fiefdoms, where the seasonal lifting of prohibition for carnival brought on the ‘allowed fool’ (Shakespeare 2006) for parody’s brief upending of the hierarchical order, when high became low, mouth met anus, and wise became mad, even within the Pater Noster of the Holy Mass. (Bakhtin 1980: 78). How the revisitation of parody might illuminate contemporary cultural politics is a driving question behind this collection, a questionmade more urgent by recent global developments of terror.

Cicero, Tullia, and Marcus: Gender-Specific Concerns for Family Tradition?

A fair number of Cicero's letters reveal his concern for his daughter Tullia and his son Marcus. Recent scholarship has read these letters as evidence for a ‘natural’ emotional attachment of a father to his children, in reaction to Philippe Ariès's opposite claim. This chapter considers whether Cicero's letters can be analysed only as expressions of paternal affection. The fact that the pater familias Cicero occupies a political position simultaneously in his nuclear family, his domus, and the Senate, results in a concern for his prestige within the social field of the aristocracy. And this concern is necessarily conferred upon his support of the education and the social and political career of his children. The chapter traces the gender-specific differences between Cicero's treatment of Tullia and Marcus, shows the social construction of parental affection, and contributes to a further understanding of the different functions of daughters and sons in the social force field of family memory.

A nearby M Star with tree Transitting Supter-Earths Discovered by K2

Small, cool planets represent the typical end-products of planetary formation. Studying the architectures of these systems, measuring planet masses and radii, and observing these planets' atmospheres during transit directly informs theories of planet assembly, migration, and evolution. Here we report the discovery of three small planets orbiting a bright (K-s = 8.6 mag) M0 dwarf using data collected as part of K2, the new ecliptic survey using the repurposed Kepler spacecraft. Stellar spectroscopy and K2 photometry indicate that the system hosts three transiting planets with radii 1.5-2.1 R-circle plus, straddling the transition region between rocky and increasingly volatile-dominated compositions. With orbital periods of 10-45 days the planets receive just 1.5-10x the flux incident on Earth, making these some of the coolest small planets known orbiting a nearby star; planet d is located near the inner edge of the system's habitable zone. The bright, low-mass star makes this system an excellent laboratory to determine the planets' masses via Doppler spectroscopy and to constrain their atmospheric compositions via transit spectroscopy. This discovery demonstrates the ability of K2 and future space-based transit searches to find many fascinating objects of interest.
