Cosmos 1980-01-01T00:00:00Z This kind of geometry is referred to as spherical geometry. Astronomy 2016-10-13T00:00:00Z Two main possibilities then arise: one is spherical geometry, in which parallel lines can eventually touch, in the way that Earth’s meridians cross at the poles; the other is hyperbolic geometry, in which they diverge. Mathematicians create warped worlds in virtual reality 2017-03-20T04:00:00Z One of the interesting properties of spherical geometry is the fact that on a given sphere, the angles in a triangle completely determine the side lengths and area of the triangle. Grapefruit Math 2015-05-19T04:00:00Z The spherical geometry of oil silos provides optimal orientation for harvesting sunlight year-round.

Sidelights on Relativity I taught a topology and geometry class this semester, and one of the topics we covered was spherical geometry. Grapefruit Math 2015-05-19T04:00:00Z Indeed, it is very easily calculated by means of spherical geometry, what a great extent of the earth's area I beheld. The Works of Edgar Allan Poe — Volume 1 The representation given above of spherical geometry on the plane is important for us, because it readily allows itself to be transferred to the three-dimensional case.
