In this paper Euclidean and hyperbolic discontinuous isometries* are discussed and compared. The graphic artist M.C. Escher (1898-1972) produced works which have for the structure points, lines, and angles, which repeat in the plane (Euclidean and...
steps required to represent the knot as a polygon in the cubic lattice. Several lower bounds for the lattice step numbers of different knots have been obtained by computer simulations but the exact value of the lattice step number seems to be ...
A study was performed using a convenience sample of 90 students at a northeastern community college to determine gender differences of math anxiety and its effect on math avoidance. Four sections of an introductory English class were given a...
The hypothesis that increased stress on rocks induced during deformation produced microstructures on minerals, which gradually intensifies as one gets closer to an isograd line. This assumption is based on increasing microfractures in the fold...
