[DaveMakesStuff] demonstrates a great technique for 3D printing a sphere; a troublesome shape for filament-based printers to handle. As a bonus, it uses a minimum of filament. His ideas can be ...

3D shapes, they have 3 dimensions ... Triangles, pentagons, hexagons, any shape. And a circle becomes a sphere with just one large, curved face, like a ball. Perfect for, uh, rolling.

Over the years, mathematicians found that the twisted shapes exist in dimensions 2, 6, 14, 30 and 62. They also showed that ...

[Carl Bugeja] finds the engineering behind the Las Vegas Sphere fascinating ... and math to lay out an unusual panel shape which covers a small 3D printed geodesic dome. Much easier said that ...

Some cubes of ice, a set of dice, a battered cardboard box. GIRL 1: Now the next shape is a sphere. Try to make yourself into a sphere – a big ball! The boy tries to make himself into a sphere ...

You live on the surface of a giant sphere, like a beach ... inside a 3D space (your room). Such loops are called mathematical knots. Geometric topology is a beautiful and complex subject, and ...
