I Over the last decade or so, much has been written about the new "science of complexity". From journalistic hyperbole to cutting edge research, it is widely assumed that the science of complexity has indeed discovered something new, that is worthy of the attention of scientists and philosophers alike. But what? An overarching principle that connects the study of complex systems across the phys...

We explore the minimum energy configurations of repelling particles distributed over n possible locations forming a toric grid. We conjecture that the most energy-efficient way to distribute n/2 particles over this space is to place them in a checkerboard pattern. Numerical experiments validate this conjecture for reasonable choices of the repelling force. In the present paper, we prove this co...

In English (1) tense is marked both on auxiliary do and the lexical verb. In (2), is occurs in two positions. In (3), the functional element no is realized in a relative clause, even though adult Japanese has no overt functional morpheme in this position. In (4), the ‘bound noun’ kes is likewise realized in a relative clause, even though no morpheme appears in this position in adult Korean. The...

Nanomaterials and the Precautionary Principle doi:10.1289/ehp.1103687 Kessler (2011) provided a valuable update on the current state of research and regulatory pol­ icy concerning nano materials. However, the article could give the mis leading impression that the precautionary principle constitutes a straightforward guideline for improving public policy in this area. Instead, the precautionary ...
