We are all familiar with the hassles that accompany air travel. We shuffle through long lines, remove our shoes, and carry liquids in regulation-sized tubes. And even after all the effort, we still wonder if these procedures ...

Most of the time we take light for granted. It arrives with the sunrise everyday and we turn it on with a flick of a switch every night. It appears to be ephemeral and benign to us humans but there is more to light than meets ...
