A tesseract is a 4 dimensional object projected into a 3 dimensional world. A shadow if you will.
What is RSA?
Well then probably because you need higher math to even understand it.
The best way to understand multidimensional ideas is to go down one level. Imagine you being in 3d viewing a 2 world on a piece of paper. Now think about how you could interact with the people who live in that world. How could you communicate? What would it look like to them if you stuck your finger into their world? If you drew a line between two people in that world they would not be able to see each other but you being, "above," so to speak can see both of them at the same time.
You have essentially a, "higher," view.
No idea.
I sometimes suspect though, that the mind is a sort of interface to all the other dimensions. When you think about it, it is not bound by time or space, we can, "imagine," just about anything regardless of any limit.
Yeah, but I suspect that is only because the shape they picked to represent the idea was a cube and not some other shape.
Is this supposed to be some subtle muh joo shillery?
I always loved getting those order forms, couldn't wait to get some new books.
