Kaleidoscope mirror symmetry inspires new design for optical tools, technologies Using multiple-axis symmetry inspired by kaleidoscopes, new polarization designs can control spin angular momentum ...

Non-rotationally symmetric surfaces are produced by the ability to servo a tool in a coordinated manner, with a workpiece rotating on a two-axis lathe. The diamond machining of far off-axis segments ...

We show that the sporophyte rooting structures of all four plants comprised regions of plagiotropic (horizontal) axes that developed unicellular rhizoids on their underside. These regions of axes with ...
