what do you mean by 4 dimensions?

Answer 1

the fourth dimension is often considered to be time . . .

Answer 2

Generally it is said that TIME is the fourth dimension. If yes, there are several transcendental and metaphysical things and concepts needs place in the subject of dimension. What is the dimension of energy then . What is the dimension of experience or knowledge that you have. No doubt, they also exist.
Actually, the transcendental subjects like time, energy, knowledge etc. should be put into a different category of dimensions other than the perceivable like solids, liquids, gases, space, etc. Although, we can relate them with the perceivable as Einstein did made a paradigm shift in the field of science by relating mass and energy by c^2 in his equation E= mc^2.
When we think off the volume of space thinking of time as 4th dimension requires a conversion factor that relates space and time or solid and time, without that our knowledge will be incomplete , consequently long debate on it continues.
Therefore I opine that a cube in the forth dimension is the set of cubes arranged side by side in the form of a line which we may call as cubic line.
i.e. A` Point' is dimensionless, `line' is mono dimensional, `area' is bi-dimensional and `cube' is tri-dimensional, moreover `line of cubes’ or cubic line is 4th-dimensional,..... in the same way we can assume nth-dimensional figure, since dimension is a notion created for our convenience to understand nature and space around us.

Answer 3

The concept of a fourth dimension is one that is often described in considering its physical implications; that is, it is known that there are three dimensions: length (or depth), width, and height. The fourth dimension is orthogonal to the other three spatial dimensions. The cardinal directions in the three known dimensions are called up/down (altitude), north/south (longitude), and east/west (latitude). When speaking of the fourth dimension, an additional pair of terms is needed. Attested terms include ana/kata (sometimes called spissitude or spassitude), vinn/vout (used by Rudy Rucker), and upsilon/delta. The fourth dimension is often identified with time, and as such is used to explain space-time in Einstein's theories of special relativity and general relativity. In this case, the concept of an additional spatial dimension would be referred to as the fifth dimension. In this article, however, we discuss the implications of considering the fourth dimension as another spatial dimension.

Answer 4

Fourth dimension often refers to time; this was first widely used by Einstein. In addition to length, width, and height, matter has another property; that is time.

Graphically, this would mean another axis, making it quite distorted as our vision is only limited to three dimensions. Time is usually introduced to equations using parametric form.

An additional spatial dimension would be orthogonal to the other three; I think the link below does a nice job explaining.

Answer 5

I believe there are only the three dimensions of space, as string theory is only theory, not proven reality. I don't believe time is a dimension, but a derivative of space and motion. A clock is simply a device in which something moves across an interval of space, and we call it time.

Answer 6

Length, Width, Height, and Time.

You should look into String Theory, it is facinating. It states that there are 12 dimensions. And we are only aware of 4

Answer 7

We mean that there is a maximum of four numbers needed to describe the location of something in our universe.

Answer 8

they are four dimesions of nature
ie.lenght width height time,ect........
i think there are 13 dimensions

Answer 9

linear dimentions length width height, 4th time

Answer 10

alens there are 4 denmision
