Muscles work by getting shorter. we say that they contract, and the process is called contraction. muscles are attached to bones by strong tendons. when a muscle contracts, it pulls on the bone. As a result of this rapid development of technology, we often take things for granted. one of these is the wheel. take a look around, and you will see wheels everywhere, be it as tyres, or in everyday machinery. the wheel has even been imbued with symbolic meanings, most famously, perhaps, as a metaphor for the never ending cycle of life.

“posthumously published, why the wheel is round was written by vogel (1940–2015), a celebrated researcher and author in the field of biomechanics. he focuses on the intersection of biology (specifically the physics of muscles, joints, and other “moving parts”) and mechanical engineering—often comparing a biological system to a mechanical system.
