Mathematical evidence indicates that our universe is flat, but it could be infinitely big, as well. You can figure out if an object is flat with a simple pencil-and-paper geometry exercise. To ...

With the help of powerful computers, researchers discovered a four-sided shape that naturally rests on one side, and built a ...

Scientists from The Hebrew University of Jerusalem have created wood ink that can be extruded into flat wooden structures, self-morphing into complex 3D shapes as they dry and shrink.

The net of a 3D shape is what it looks like if it is opened out flat. There are many types of nets for the different 3D shapes. A net is made from polygons that can be folded and joined to make a ...

In their paper, titled "Creating Furniture-Scale Deployable Objects with a Computer-Controlled Sewing Machine," they describe a collection of functional flat-to-shape artifacts they created with ...

Third dimension: example of an origami mechanical metamaterial. ... These flat materials deform into 3D shapes in response to light, heat and electromagnetic fields, with the initial alignment of the ...

CAMBRIDGE, MA -- Researchers at MIT and elsewhere have designed 3-D printed mesh-like structures that morph from flat layers into predetermined shapes, in response to changes in ambient ...
