A Millennium of Liquid Crystals
Liquid crystals—the mysterious expression used to describe the class of materials that can flow yet remain ordered—have a surprisingly long history reaching well back into the last millennium. In this fly-over of the field of liquid crystals, we will see the high points and be introduced to some of the scientists who trekked through the details.

Optical coherence tomography (OCT) is a fundamentally new type of optical imaging modality that performs high-resolution, cross-sectional tomographic imaging of the internal microstructure in materials and biological systems, by measuring the echo time delay and magnitude of backscattered light.

Understanding how cirrus, cirrostratus and cirrocumulus clouds and the recognition of ice's presence are intimately tied to halos.
