Some Comments on Professor

In a recent issue, this journal published an article by Professor Robert S. Summers reviewing and commenting critically upon a recent book by Professor H. L. A. Hart of Oxford entitled The Concept of Law. Among other things, Professor Summers criticized Professor Hart for stressing rules to the neglect of other elements of a legal system and for succumbing to reductionist tendencies in the anal...

Opaline Microfossils in Some Michigan Soils

Some Comments on Physical Mathematics

These are some thoughts that accompany a talk delivered at the APS Savannah meeting, April 5, 2014. I have serious doubts about whether I deserve to be awarded the 2014 Heineman Prize. Nevertheless, I thank the APS and the selection committee for their recognition of the work I have been involved in, as well as the Heineman Foundation for its continued support of Mathematical Physics. Above all...

SIMS analyses of the oldest known assemblage of microfossils document their taxon-correlated carbon isotope compositions.

Analyses by secondary ion mass spectroscopy (SIMS) of 11 specimens of five taxa of prokaryotic filamentous kerogenous cellular microfossils permineralized in a petrographic thin section of the ∼3,465 Ma Apex chert of northwestern Western Australia, prepared from the same rock sample from which this earliest known assemblage of cellular fossils was described more than two decades ago, show their...
