Depending on whether you are looking for a "Walker" related to scientific history, medical devices, or sleep science, here are three highly interesting and influential papers: 1. The "Molecular Machine" (Biochemistry)

If you are interested in the Nobel Prize-winning work of , his 1994 paper is a landmark in biology. It revealed that a tiny motor in our cells literally spins to create energy.
