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 ...

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 ...

To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...

Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

Over the past century, archaeologists have uncovered more than 1,600 Proto-Elamite inscriptions, but only about 43 in Linear Elamite, scattered widely across Iran. Illustration by Meilan Solly / ...
