Fractals under the Microscope or Reaching beyond the Dimensional Formalism of Fractals with the Wavelet Transform
Recently, there has been a tendency to see natural phenomena as resulting from the action of dynamical processes. These processes (and the objects to which they give rise) are surprisingly often well characterised using some sort of hierarchical approach. It is also one of the key features of fractal geometry that the action of dynam-ical systems can result in intrinsically hierarchical structu...

متن کاملAn Optical Super-Microscope for Far-field, Real-time Imaging Beyond the Diffraction Limit
Optical microscopy suffers from a fundamental resolution limitation arising from the diffractive nature of light. While current solutions to sub-diffraction optical microscopy involve combinations of near-field, non-linear and fine scanning operations, we hereby propose and demonstrate the optical super-microscope (OSM) - a superoscillation-based linear imaging system with far-field working and...
متن کاملThe philosophy beyond the polygamy of holy Prophet
Holy prophet’s polygamy has since long been used as a pretext by the orientalists in order to twist the real face of Islamic mission.
