This cuboid contains 12 small cubes. Each small cube has a volume of 1 cm 3. The volume of the cuboid is 12 cm 3. The surface area of a 3D shape is the total area of all the faces. A cube has six ...

Tactile display capable of reproducing 3d shapes and textures on flat surfaces for various applications. Immersive applications such as information delivery for the visually impaired, vehicle UI, ...

A team led by aerospace Ph.D. student Ivan Wu and his advisor Jeff Baur has developed a low-energy, scalable technique that ...

3D printers build objects by cross-section, one layer at a time from the ground up—gravity is the limiting factor. But what if it wasn’t? Using proprietary 3D printing materials, Petr Novikov and Saša ...

Haptic feedback has become a common feature of recent technology, but such systems usually rely on stimulation of parts of the user’s body via direct mechanical or acoustic vibration. A new technique ...

Scientists have long wondered if there are physical constraints that limit the possibility of how large an organism can become through evolution. A new study involving 54 species of sharks indicates ...

A prism has a constant cross-section throughout its length. When the cross-section is a triangle, the prism is called a triangular prism. When the cross-section is a hexagon, the prism is called a ...
