False Dichotomy

Don Ihde examines the “congenital dystopianism” shared by environmentalists, environmental philosophers, and philosophers of technology. Each group employs a “rhetoric of alarm” that connects the use of technologies with environmental degradations. Ihde calls attention to how excessive rhetorical strategies have locked us into a false dichotomy: either technological-environmental utopianism or dystopianism. The problem is that we have not yet fully diagnosed either what our technologies can or should do, or what the environmental crises actually are. So long as we continue to accept either utopian or dystopian forecasts we are unlikely to bring either technologies or ecosystems into appropriate focus. Techno-environmental problems are complex, ambiguous, and interwoven; they rarely lend themselves either to an easy techno-fix or simple solution. The hardest problem of them all is how to turn major actors in the economy green: large scale development projects and multinational corporations. The challenge for a proactive philosopher is to get on the ground floor of technological research and development in order to help figure out how to green the economy itself.

Axial Waves

Turbulent vortex dynamics is investigated in triply periodic turbulent flow with Kida’s high symmetry (Kida, J. Phys. Soc. Japan, vol. 54, 1985, pp. 2132–2136) by means of unstable periodic motion representing both the statistical and dynamical properties of turbulence (van Veen et al., Fluid Dyn. Res., vol. 38, 2006, pp. 19–46). In the periodic motion, the large-scale columnar vortices, the smaller-scale vortices and the large-amplitude axial waves on the large-scale columnar vortices are detected. In terms of mutual dynamical interaction between the large-scale columnar vortices and smaller-scale vortices, we demonstrate a cyclic process of excitation of the axial waves, which leads to large-amplitude fluctuations of the total kinetic energy and enstrophy. This cyclic process is characterised by three distinct phases and is therefore reminiscent of the regeneration cycle of near-wall turbulence structures (Hamilton et al., J. Fluid Mech., vol. 287, 1995, pp. 317–348). Notably, such oscillatory behaviour is observed even in freely decaying turbulence as a consequence of the instantaneous energy transfer from smaller to larger scales.

Large-scale nanoporous amorphous silica nanostructure is fabricated via a simply etched approach and effective thermal evaporation process. The nanoporous amorphous silica was synthesized by a general and scalable process via etching by metal particles on the silica sheets. In this study, we elucidated how a nanoporous structure was performed and the addition of indium is the key factor that determined the formation of the nanoporous structures. The morphology and the sizes of the porous structure could be tunable by the sizes and the shape of the metal. We discovered a promising optical property in the as-synthesized nanostructures, which have a photoluminescence in an intensive ultraviolet emission as well as a broad visible emission at room temperature.
