A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

Visually, the “Klein bottle” doesn’t seem all that impressive. To understand why, we have to travel far back to the ancient ...

A laboratory breakthrough in Japan could reshape how cars and aircraft are engineered. Researchers at Nagoya University have ...

The ocean is saturated with microplastics. While we know the location of the great garbage patches, where plastic particles ...

The Audi five-cylinder isn’t long for this world, but it’s still around to celebrate its 50th birthday. Inline-five engines have been around since the ’30s, but it was only in the ’70s that they ...

Inline-five engines have been around since the '30s, but it was only in the '70s that they started to really work. That's all thanks to the 1974 Mercedes-Benz 240D 3.0 (known as the 300D in the US), ...

SAM 3D Objects is a foundation model that reconstructs full 3D shape geometry, texture, and layout from a single image, excelling in real-world scenarios with occlusion and clutter by using ...

Abstract: Recent research on transistors has focused on gate-all-around (GAA) structures, which possess better gate controllability than previous fin field-effect transistor (FinFET) structures. The ...
