# Can we see higher dimensions?

## Can we see higher dimensions?

The things in our daily life have height, width and length. But for someone who’s only known life in two dimensions, 3-D would be impossible to comprehend. And that, according to many researchers, is the reason we can’t see the fourth dimension, or any other dimension beyond that.

Is there a way to visualize the fourth dimension?

Likewise, we can describe a point in 4-dimensional space with four numbers – x, y, z, and w – where the purple w-axis is at a right angle to the other regions; in other words, we can visualize 4 dimensions by squishing it down to three.

What is the 7th dimension called?

7-polytope
A polytope in seven dimensions is called a 7-polytope. The most studied are the regular polytopes, of which there are only three in seven dimensions: the 7-simplex, 7-cube, and 7-orthoplex.

### What is the best way to visualize high-dimensional data?

Parallel coordinates are a popular method for visualizing high-dimensional data. What kind of visualization is best for your data in particular will depend on its characteristics– how correlated are the different dimensions?

Is it possible to imagine dimensions higher than the three dimensions?

We have a hard time imagining higher dimensions, but there’s more than one way to see them. It’s not easy to imagine dimensions higher than the three that we exist in, but in math, higher dimensions are used all the time. As pointed out in this video from 3Blue1Brown, there are some downsides to the fact that we can’t visualize these dimensions.

What is multidimensional scaling?

The buzzword I would search for is multidimensional scaling. It is a technique to develop a projection from the high dimensional space to a lower space (2 or 3 dimensional) in such a way that points which are close in the full space will be close in the projection.
