Motivated by the fact that in a space where shortest paths are unique, no two meet twice, we study question posed Greg Bodwin: Given geodetic graph $G$, i.e., an unweighted which path between any pair of vertices is there philogeodetic drawing $G$ curves at most once? We answer this negative showing existence graphs require some to cross least four times. The bound on number crossings tight for...

The human EEG can be driven by rhythmic photic stimulation with a frequency of about 10 cps. This has been known for some time (WALTER 1953). On the other hand, the relation between the visually evoked potential and the driving of the EEG has remained obscure because of the difficulty of obtaining the evoked potential from the human scalp . With the development of the averaging technique the re...
