If we live in a 3D world, we say the dimensions are length, width, and height.
We can add Time in there for another dimension.
There is (a lot of) talk that we actually live in a 10+ dimensional world. I've heard tell that the other dimensions are theorized to be crazy shapes that fold in on themselves. ( Calabi-Yau shapes )
Does anyone understand this concept?
And can anyone tell me why, if length and time are dimensions why are ... say... rotation (orientation) or even temperature not considered dimensions?
They can all be measured and quantified.
