The World's Smallest Spontaneous Atomic Valentine -- Made Of Palladium Atoms | physorg.com - http://www.physorg.com/news185...
"According to the physicists observing the atoms through the Lab’s JEOL 2100F microscope, Zhiwei Wang and David Pearmain, they watched with love, but really had absolutely nothing to do with the heart formation of the atoms. Sadly, the bright, beautiful palladium Valentine will not be given to a special lady. Being only 8 nanometers in size, it can’t be seen by the human eye, and cannot even be relied upon to stay in the smallest ring setting. But we can all admire the wonderful high-angle, very high-power shot of the world's smallest and, arguably, prettiest naturally-formed Valentine." - Kurt Starnes
