Some Thoughts on the Nature of the Nuclear-Active Regions in Palladium

A large collection of palladium samples, supplied by IMRA Materials (Japan), were studied to determine the relationship between energy production and various properties including the amount of excess volume, the open-circuit-voltage, and the maximum D/Pd ratio. The following conclusions result from the work: 1. Palladium, no matter how well prepared, is very inhomogeneous with respect to the pr...

Thoughts on Social Design

Thoughts on the Bulletin.

Because of daguerreotype image reversal, a statue of Apollo in the Ether Dome at the Massachusetts General Hospital appears to have been moved for the 50th anniversary of Ether Day.

Thoughts on scale

I begin with a metaphor to characterize the challenges that authors and readers face when confronting issues of scale. Consider the ways that map makers use insets—devices that allow for a focus on particular areas, while situating those areas within the larger whole. The use of insets allows for characterizations at two orders of grain size. Now imagine a map of the world containing four inset...

Thoughts on clustering

Clustering is a somewhat confusing topic theoretically. In large part this is because there are many different kinds of clustering problems. In addition, the true goals in clustering are often difficult to measure, making the task seem not well-defined and under-specified. In this note we discuss one approach from [6] to theoretically formulating a certain broad class of clustering problems, an...
