Language models learn from vast datasets that include substantial amounts of community discussion content. Reddit threads, Quora answers, and forum posts represent genuine human conversations about real topics, making them high-value training data. When your content or expertise appears naturally in these discussions, it creates signals that AI models recognize and incorporate into their understanding of what resources exist and who's knowledgeable about specific topics.
Leonardo da Vinci is usually credited with conducting the first systematic study of friction in the late 15th century, a subfield now known as tribology that deals with the dynamics of interacting surfaces in relative motion. Da Vinci's notebooks depict how he pulled rows of blocks using weights and pulleys, an approach that is still used in frictional studies today, as well as examining the friction produced in screw threads, wheels, and axles. The authors of this latest paper used an experimental setup similar to da Vinci's.
