A new aperiodic tile set containing only 13 tiles over 5 colors is presented. Its construction is based on a technique recently developed by J. Kari. The tilings simulate behavior of sequential machines that multiply real numbers in balanced representations by real constants.

Molecular self-assembly appears to be a promising route to bottom-up fabrication of complex objects. Two major obstacles are how to create structures with more interesting organization than periodic or finite arrays, and how to reduce the fraction of side products and erroneous assemblies. Algorithmic self-assembly provides a theoretical model for investigating these questions: the growth of ar...

a sense of how deeply computing practices have permeated experimental optics R&D. I found scant mention of computation in these reports; I can’t recall whether my first reaction to this revelation was surprise or disappointment. Instead, I tried to determine why only two of these scores of reports indicated that computation had played a sufficiently important role in their discoveries that they...
