# What is volume of N dimensional sphere?

## What is volume of N dimensional sphere?

In general, the volume of the n-ball in n-dimensional Euclidean space, and the surface area of the n-sphere in (n + 1)-dimensional Euclidean space, of radius R, are proportional to the nth power of the radius, R (with different constants of proportionality that vary with n).

## What are the properties of a sphere?

Characteristics of a Sphere

• Spheres are perfectly symmetrical.
• It has onesurface, not a face, as it isn’t flat.
• All points are equidistant from the centre.
• It is not a polyhedron (a solid shape with more than 6 faces)
• Of all shapes, a sphere has the largestvolumeover the shortest surface.

What is a multidimensional sphere?

So that a two dimensional sphere is simply the 2D surface of an “ordinary” ball in three dimensional space.

### Is N sphere open?

In this context, an n-sphere is indeed a closed (compact) manifold. Note that compactness (as opposed to “openness”) is really an attribute of a topological space.

### What is description of sphere?

sphere, In geometry, the set of all points in three-dimensional space lying the same distance (the radius) from a given point (the centre), or the result of rotating a circle about one of its diameters. The components and properties of a sphere are analogous to those of a circle.

Is the universe a 4D sphere?

The observable universe is a tiny part of this 3-sphere; hence it looks flat (3-dimensional Euclidean space) up to measurement precision (about 0.4% at the moment). Adding time makes the universe 4-dimensional. The observable part is similar to a 3+1-dimensional Minkowski space-time.

#### What is n-dimensional Euclidean space?

A physical n-dimensional Euclidean space is a space of points or vectors where each point or vector is identified mathematically by n real numbers (x1 , . . . , xn) , after we fixed a coordinate system {e1,… ,en} in the physical space. In the sequel F is either R or C.

#### What is the N in pV nRT?

moles
The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant.

What is a Kugel?

Christmas Kugels. “Kugel” is the name of heavy glass Christmas ornaments that were made in Germany from as early as 1840 to the early 1900s.

## What colors are kugels made of?

Original kugels are generally lined inside with silver. The outside colors are red, cobalt, blue, green, silver, gold and amethyst. There is a hole in the top of each ornament which is concealed by a brass cap.

## What is a Kugel neck or pike?

The raised glass surrounding the hole is technically called a pike or spear but most collectors just say “neck” which is the term we’ll use. Tops of the new necks are very rough having a “cracked off” appearance. Generally, most old kugels have much smoother tops although this can vary with the skill in which the old ornament was made.

How much is a glass Kugel worth?

New kugels retailed for about \$7.50. Originals sell for \$50-300 with some rare examples selling for \$1,000 and more. CAUTION: Do not confuse kugels, which were made ca. 1840-1900 and are thick heavy glass, with the thin-walled glass ornaments made after 1918.
