In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the surface of a sphere. The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces.
In classical mechanics, space and time are different categories and refer to absolute space and time. That conception of the world is a four-dimensional space but not the one that was found necessary to describe electromagnetism. The four dimensions of spacetime consist of events that are not absolutely defined spatially and temporally, but rather are known relative to the motion of an observer. Minkowski space first approximates the universe without gravity; the pseudo-Riemannian manifolds of general relativity describe spacetime with matter and gravity. Ten dimensions are used to describe string theory, and the state-space of quantum mechanics is an infinite-dimensional function space.

The "holy" shows your purpose
And you buy it, you buy it?
If it's your faith, is this your fate?
We all fail
We all break
So we fight it back for no reason but ourselves
We fight!
We fight it back!
We'll not abandon ourselves
We were stalled out and empty
On highways cracked and blanked out
And if in someway we were to get out
To walk out, we'd have to
No matter how far or high up
We all fail
We all break
So we fight it back for no reason but ourselves
We fight!
We fight it back!
In the dark it looked like they were sleeping
They looked like how I felt, how cold they were
And who would go to trouble to arrange them like that?
And in my panic, in my grief it struck me.
If it burns too bright then it'll burn too fast
We all fail
So we fight it back for no reason but ourselves
We fight!
We fight it back!
