In previous work developing and experimenting with a large-scale social simulation, we successfully employed an ad hoc cognitive model, a formula-based decision function. We explain why we now believe that a “fast and frugal” cognitive architecture to be superior based on its indistinguishable computational efficiency and much better cognitive plausibility.

By scanning the beam in a cold objective lens system, we achieve wide fields of view without compromising image quality. Photoluminescence from single nitrogen-vacancy centers in high purity diamond is used to illustrate the imaging and stability performance of the microscope.
