Rolf William Landauer

Died 27 Apr 1999 at age 72 (born 4 Feb 1927).German-born American physicist known for his formulation of Landauer's principle concerning the energy used during a computer's operation. Whenever the machine is resetting for another computation, bits are flushed from the computer's memory, and in that electronic operation, a certain amount of energy is lost. Thus, when information is erased, there is an inevitable "thermodynamic cost of forgetting," which governs the development of more energy-efficient computers. While engineers dealt with practical limitations of compacting ever more circuitry onto tiny chips, Landauer considered the theoretical limit, that if technology improved indefinitely, how soon will it run into the insuperable barriers set by nature?«

The recital

A soldier stationed in the South Pacific wrote to his wife in the States to please send him a harmonica to occupy his free time and keep his mind off of the local women. The wife complied and sent the best one she could find, along with several dozen lesson & music books.

Rotated back home, he rushed to their home and thru the front door. "Oh darling" he gushed, "Come here... let me look at you... let me hold you ! Let's have a fine dinner out, then make love all night. I've missed your lovin' so much !" The wife, keeping her distance, said, "All in good time lover. First, let's hear you play that harmonica."
