One of Georg Simmel's more contentious claims at the turn of the nineteenth century was that the abstract workings of a mature money economy were mirrored ...

This paper examines a weightless neural network traind to perform a probabilistic, iconic prediction task. The paper discusses both the network architecture and training scheme used. The iconic prediction task is examined both with and without a controlling input. Finally some speculative parallels are drawn between the system behaviour and prediction in biological systems.

The discrepancy between the observed and the expected gravitational redshifts in the Sun are often assumed to be caused by Doppler shifts in the line forming elements. An elaborate system of currents, which was surmised for explaining the discrepancy, has lead to contradictions with observations. Contrary to general belief, the Fraunhofer lines are found to be plasma redshifted and not gravitat...
