Compared to Euclidean geometry, hyperbolic geometry presents many difficulties for a coordinate system: the angle sum of a quadrilateral is always less than 360°; there are no equidistant lines, so a proper rectangle would need to be enclosed by two lines and two hypercycles; parallel-transporting a line segment around a quadrilateral causes ...
The idea of reducing geometry to its characteristic group was developed particularly by Mario Pieri in his reduction of the primitive notions of geometry to merely point and motion. Hyperbolic motions are often taken from inversive geometry : these are mappings composed of reflections in a line or a circle (or in a hyperplane or a hypersphere ...
In group theory, more precisely in geometric group theory, a hyperbolic group, also known as a word hyperbolic group or Gromov hyperbolic group, is a finitely generated group equipped with a word metric satisfying certain properties abstracted from classical hyperbolic geometry. The notion of a hyperbolic group was introduced and developed by ...
During the early days of the COVID-19 pandemic, Oz lobbied the Trump administration to rush trials of the antimalarial drug hydroxychloroquine to treat the virus.
Three of America's best known TV doctors are taking their medicine after making inflammatory statements about the coronavirus. Dr. Oz, other TV docs face criticism for coronavirus cracks Skip to ...
Hyperbolic geometry is a non-Euclidean geometry where the first four axioms of Euclidean geometry are kept but the fifth axiom, the parallel postulate, is changed. The fifth axiom of hyperbolic geometry says that given a line L and a point P not on that line, there are at least two lines passing through P that are parallel to L. [1]
Dr. Drew Pinsky, Dr. Mehmet Oz, and Dr. Phil McGraw have all been criticized in recent days for making statements on television and podcasts that appear to downplay the dangers of COVID-19, for ...
