Saturday we had a visitor accompanied by his son. The father had several Tek friends, owned several Tek scopes, and was a career geologist.
His son, Will Gannett, is a Ph D candidate in Physics attending Berkeley. As any proud father might, dad had us Google an article his son co-authored: Nanoscale Reversible Mass Transport Memory.
In this paper the Berkeley and the Pennsylvania State Physicists describe a robust memory device, nanomechanical in nature, with an estimated configurable density exceeding 1 terabits/sq in! Current hard disks in 10-100GB/sq in density have an estimated storage lifetime of only 10-30 years! The thermodynamic stability of these new devices at room temperature is in excess of one billion years!
I was disappointed that the only measuring device mentioned was a Transmission Electron Microscope, a device Tek once developed, and then killed in 1969.
