Some Neutral Theorems of Plane Geometry,go a little beyond Euclid in that they use the notion of continuity as it appears in calculus. Results in the last two sections go beyond Euclid in that the ideas in them are more recent, as in the Jordan Curve Theorem or the study of isometries.

Connections with the Lorentz Group of Special Relativity,and show an isomorphism between the direct isometry group of three-dimensional hyperbolic space and the Lorentz group in three space variables and time. We then describe the so-called relativistic velocity space and show that it has the same geometry as the three-dimensional hyperbolic space.

Dissipative Structures and Chaos...), two distinct rapidly moving boundaries with ..,w = 189 and 385 S are registered on the sedimentation profiles. These boundaries correspond to 24-mers and 70-mers (the molecular masses of associates were estimated using the Mark-Houwink—Kuhn—Sakurada equation, assuming a spherical form. The kin
