He invented the insert device, which was stuffed into a hole drilled in Napiers bones, which allowed a metal plank to go in. Although it wasnt a great improvement, his science in the insert device helped to the creation of Condoms by his son Samuel.
General features of bones are called bony prominences and are used to locate muscles in the body.
I do not think so.

Yes, Napier's bones are still used today, primarily as an educational tool to teach basic multiplication and numeric concepts. While modern calculators and computers have largely replaced manual calculation methods, the bones demonstrate early mathematical principles and the history of computation. They can also serve as a hands-on resource in classrooms to engage students in learning about mathematics.
