A mathematical technique for representing solid objects. Unlike wireframe and surface modeling, solid modeling systems ensure that all surfaces meet properly and that the object is geometrically ...

Take [AlphaPhoenix]’s simple question: “Are solid objects really solid?” On the face of it, this seems like a silly and trivial question, but the thought experiment he presents reveals more.

Solid objects generally produce a splash upon entering water. Surprisingly, a small change in the surface chemistry of an object can turn a big splash into an inconspicuous disappearance and vice ...

These objects were previously discovered by the Japanese ... While infrared observations are effective for studying solid materials, radio observations are more useful for analyzing the motion ...
