I'm interested in spherical geometry in 4 dimensions. Surely someone has done this, but what is it called? I can't find it.
N-spherical geometry is a type of geometry that deals with the properties and measurements of objects on a sphere with N dimensions. It is an extension of traditional spherical geometry, which deals with objects on a 3-dimensional sphere.
N-spherical geometry differs from Euclidean geometry in that it operates on a curved surface (a sphere) rather than a flat surface. This means that some of the traditional rules and theorems of Euclidean geometry, such as the parallel postulate, do not apply in N-spherical geometry.
Yes, N-spherical geometry has many practical applications, particularly in fields such as astronomy, physics, and geography. It can be used to study and map the surface of Earth or other planetary bodies, as well as to understand the behavior of objects in space.
It can be challenging to visualize N-spherical geometry, as it operates in more than three dimensions. However, some mathematicians and scientists use techniques such as projection or stereographic mapping to represent N-spherical objects in 3-dimensional space.
Yes, there are several real-life examples of N-spherical geometry. One example is the mapping of the Earth's surface, which is often represented as a 2-sphere. Another example is the study of the universe, which is believed to have a 3-sphere shape. Additionally, some physical phenomena, such as gravitational lensing, can only be explained using N-spherical geometry.
