Light is slowed to the speed of an Olympic sprinter as it passes through a ruby. Bright and dark regions of an image are slowed by similar amounts, which requires storage of the optical energy. Understanding slow light is a step towards faster and more efficient all-optical computer processing.

Image:

Crytallographic orientation map of the calcite fibres of the shell of the brachiopod, Terebratulina retusa. Fibres are 10 microns wide. Image generated by electron backscatter diffraction (EBSD) analysis. Colours indicate crystallographic orientation. Since each fibre has a single colour, this indicates that they are each single crystals.

Deriving the coastal low-water line helps fix the maritime boundary of a nation and monitoring line movements allows detection of erosional or accretional changes to beach and nearshore seabed.Erosion and flood risk is determined by elevating the low-water line to predicted future sea levels.

Here shows an original microstructure photography of Ti-alloy by Scanning Electron Microscope (SEM) technique. Coincidentally, the alloy segregation forms a similarly bowknot shape, which is full of aesthetic feeling and impresses us upon the magic and fun of our scientific exploration field.
