Mathematicians’ Favorite Shapes Hold the Key to Big Mathematical Mysteries ...

Crows can recognize geometric patterns, suggesting that humans aren't unique in understanding shape structure.

Scientists tested crows on their ability to recognize “geometric regularity,” a skill previously assumed to be unique to ...

“We trained two carrion crows to detect a distinct display among two-dimensional visual shapes,” explain Nieder and his colleagues in their new paper on corvids’ math ability. “The crows ...

A trio of animal physiologists at the University of Tübingen, in Germany, has found that at least one species of crow has the ability to recognize geometric regularity. In their study published ...

The May issue of Scientific American takes you on a deep-sea mining mission, explores dark comets and examines an invisible ...

The other control points define the shape of the curve and they are often NOT on the curve ... Most beziers are cubic (degree 3). The higher the degree, the more the curve can wiggle. Bezier Patch A ...

The file also provides teardrop2d, which is useful for 3D printable holes. Many of the commands have module forms that produce geometry and function forms that produce a path.
