Low-friction, high-stiffness ball guides support on one rail (top) or two (bottom). The trade-offs for this performance are higher cost and more noise. The shortest path between two points is a ...

Unlike conventional ball or roller-based linear guides, hydrostatic guidance systems eliminate all metal-to-metal contact. The guide carriages move on a thin cushion of high-pressure fluid, which ...

Grade school math students are likely familiar with teachers admonishing them not to just guess the answer to a problem. But a new proof establishes that, in fact, the right kind of guessing is ...
