If you enable --privileged just to get CAP_SYS_ADMIN for nested process isolation, you have added one layer (nested process visibility) while removing several others (seccomp, all capability restrictions, device isolation). The net effect is arguably weaker isolation than a standard unprivileged container. This is a real trade-off that shows up in production. The ideal solutions are either to grant only the specific capability needed instead of all of them, or to use a different isolation approach entirely that does not require host-level privileges.
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.
