Immortality.
“Is death necessary?“, asked biologist G. R. Taylor and stated that in 1968 in the USA alone more than a thousand teams of scientists were working on the issue of growing old and the problem of death. Some people are frozen at their death. They want to be revived as soon as a cure for their disease or the aging process has been found. Most of humanity seems to have the desire to live forever. M...
متن کاملPlatonic Surfaces
If SO is a Riemann surface with a complete metric of finite area and constant curvature −1, let SC denote the conformal compactification of SO. We show that, under the assumption that the cusps of SO are large, there is a close relationship between the hyperbolic metrics on SO and SC . We use this relationship to show that lim infk→∞ λ1(Pk) ≥ 5/36, where the Platonic surface Pk is the conformal...
متن کاملPlatonic Dynamics
We develop a rigorous theory of observation for dynamical systems in Hilbert spaces. This work generalizes the results of Ott and Yorke [8] for dynamical systems in Rn.
متن کاملThe Platonic Solids
The tetrahedron, the cube, the octahedron, the dodecahedron, and the icosahedron. From a first glance, one immediately notices that the Platonic Solids exhibit remarkable symmetry. They are the only convex polyhedra for which the same same regular polygon is used for each face, and the same number of faces meet at each vertex. Their symmetries are aesthetically pleasing, like those of stones cu...
