Jet engines generally work to generate thrust by creating a high-speed exhaust. See how this is done with fans, air compressors, a combustion chamber, and fuel. The precision is specific, especially for the turbine blade. Hear exactly...

Learn all about the process and uses of the most fascinating technology known as fiber optics [3:59]

Demonstration and explanation of total internal reflection, and description of its use in fibre optics.

Today, fibers are dumb strands of material. But could those fibers have more functions than just keeping the wearer warm and dry? Just over a year ago, some of the same researchers described engineering optoelectronic fibers capable of...
