(PhysOrg.com) -- A new replica of an early modern human brain has provided further evidence for the theory that the human brain has been shrinking. The skull belonged to an elderly Cro Magnon man, whose skeleton is called ...
The optical frequency comb, a spectrum of optical radiation composed of evenly spaced and phase-coherent narrow spectral lines, was initially developed for precise time and frequency measurements. Over the past two decades, ...
