IBM Core Memory demo circa 1954. T. J. Watson Jr. and Dick Merwin

In the early 1970's I heard a story from Dick Merwin who was at that time my boss in the SafeGuard System Office (I was an enlisted engineering aide drafted into the US Army in 1971).

Dick got his Electrical Engineering degree from the Moore School and helped move the Eniac from Aberdeen Proving Grounds to Los Alamos after WWII, where he worked for several years (he said he might have been the first Customer Engineer). Dick joined IBM and started worked on core memory based on technology invented by Jay Forrester MIT, first used in the Whirlwind Computer about 1952. IBM licensed the technology and developed core memory for the Sage system, and first shipped core memory commercially with the IBM 704 in 1955.

While core memory was still new and exotic, Dick got to do a show and tell demo for T.J. Watson Jr. himself at IBM's Watson Lab.

After briefings on core memory technology by Watson Lab's Director and Dick's manager, Dick got to show his core plane sitting on a lab bench, hooked up to a test rig and oscilloscope.

As he said, and now we'll write a pattern of zeros and ones to the memory, TJ Jr. bent over the bench with interest and said "I don't see anything flipping".

The Watson Lab director nudged Dick's manager, who nudged Dick, who got to explain to TJ Jr that it was the core magnet's magnetic moment that flipped to store zero's and ones, but the cores didn't move.

2016 Paris C. Kanellakis Memorial Lecture: "Hamiltonian Paths in Antiquity" by Donald Knuth, Professor Emeritus Stanford University. 1 Dec 2016, Brown University Department of Computer Science.

About 1850, William Rowan Hamilton invented the Icosian Game, which involved finding a path that encounters all points of a network without retracing its steps. Variants of his game have turned out to be important in many modern computer applications. The speaker will give evidence that people have been interested in such questions since at least Graeco-Roman times. Furthermore, ingenious Sanskrit and Arabic documents from the ninth century, and continuing through medieval times, also reveal that this is perhaps the oldest nontrivial combinatorial problem in the history of civilization.

A reception will follow, including an "All Questions Answered with Professor Knuth" panel discussion.

This event is hosted by Sorin Istrail and Eli Upfal.
