The moment he forsook the plane he would disappear from two-dimensional space.

The Mysterious Seventh Dimension It's easy to see that Keller's conjecture is true in two-dimensional space.

We report confidence regions in the two-dimensional space of 2beta(s) and the decay-width difference DeltaGamma.

It asserts that if you cover a two-dimensional space with two-dimensional square tiles, at least two of the tiles must share an edge.

And since a three-dimensional hole in two-dimensional space would appear as a circle, a four-dimensional hole would look to us like a sphere.

"It's the same as regular two-dimensional space then," he complained.

"Okay, now it's starting to look like something different from plain old two-dimensional space," he said.
