How to weigh everything from atoms to apples using the revised SI

March 3, 2014
Author(s)
Jon R. Pratt
The fact that the unit of mass might soon be derived from the Planck constant, rather than from an artifact standard, can seem daunting and downright baffling when viewed from the vantage point of our day to day perception of mass. After all, at

The role of the face and body in person identification

December 12, 2013
Author(s)
P J. Phillips, Rice Allyson, Alice O'Toole
Information useful for identifying a person can be found both in the face and body. Previous studies indicate that when an entire person is visible, we rely strongly on the face for identification, even if the body can be useful. In this study, we measured
