Dodecahedron in Tongeren (Flanders BE) Many Central European museums exhibit pretty regular dodecahedrons, holed bronze and small spheres attached to their vertices. The dimensions are variable and move about six centimeters edge. Various enigmas and controversies surround such mathematical figures. The discussions focus on whether it was practical or an object with only a decorative or aesthetical function.
Graph Theory - An Introduction! In this video, I discuss some basic terminology and ideas for a graph: vertex set, edge set, cardinality, degree of a vertex, isomorphic graphs, adjacency lists, adjacency matrix, trees and circuits. There is a MISTAKE on the adjacency matrix; I put a 1 in the v5 row and v5 column, but it should be placed in the ...
Michæl Paukner notes about this image: Galactic Alignment 2012, Pole Shift, Mayan Calendar, Dark Rift are the most discussed topics nowadays.The Galactic Alignment is the alignment of the December solstice sun with the Galactic equator. This galactic alignment occurs as a result of the precession of the equinoxes. It occurs only once every 26,000 years, and was what the ancient Maya were pointing to.
Theoretical physicist Tegmark takes readers on an illuminating trip through cutting edge cosmology to one of the strangest ideas in a field overflowing with them: that our universe isn’t just described by math, it may actually be made out of it. Tegmark’s writing is lucid, enthusiastic, and outright entertaining, a thoroughly accessible discussion leavened with anecdotes and the pure joy of a scientist at work.
