Illustration for article titled The Perfect Gift For the Physicist Who Thinks In Ten Dimensions

Holiday shopping can be tough. Holiday shopping for that special someone can be tougher—especially if that someone happens to be a theoretical physicist. Luckily, for the brainiac who has everything there's this beautiful Calabi-Yau Manifold crystal.


But what is it, you ask? Why, put simply, it's a great representation of something we primitive humans will never be able to observe directly:

According to string theory, space-time is not four-dimensional as you might expect, but actually 10-dimensional. The extra six dimensions are believed to be compactified or rolled up into such a small space that they are unobservable at human scales of sight. Their size and six dimensions make Calabi-Yau spaces difficult to draw. But, this model shows a three-dimensional cross-section of this likely space to reveal its structure and shape. - Scientifics Online


And all that mind-bending fun is just $90! String theory, in the palm of your hand! Or, if you don't subscribe to string theory, it's a paperweight. [Scientifics Online via MSNBC]
