How To See In Four Dimensions

Posted by timothy on Saturday August 23, 2008 @08:31PM from the wrinkle-in-time-time dept.

An anonymous reader writes "Think it's impossible to see four-dimensional objects? These videos will show you otherwise. Some mathematicians work with four-dimensional objects all the time, and they've developed some clever tricks to get a feeling for what they're like. The techniques begin by imagining how two-dimensional creatures, like those in Edwin Abbot's 'Flatland,' could get a feeling for three-dimensional objects. When those techniques are transferred up a dimension, the results are gorgeous."

I know you're being facetious, but it doesn't quite work that way. Not all 4-manifolds can be embedded in Euclidean 4-space. In fact, the best we can say is they can be embedded in 8-dimensional Euclidean space.
