James Webb has a mechanical glitch. The super powerful space telescope has only been working through its scientific missions since July when NASA shared Webb's first images of the early universe. Now, ...

Earlier, we saw that the work done by friction on a particle sliding on a rough surface is negative, causing a loss in total mechanical energy as the particle slides. Here, we will address the ...

A material state known as super-lubricity, where friction between two contacting surfaces nearly vanishes, is a phenomenon that materials researchers have studied for years due to the potential for ...

Stanford’s Bob Sutton and Huggy Rao on how to boost efficiency and satisfaction while also improving innovation and decision-making. Organizations too often subject their employees and customers to ...
