Emotional well-being part-time work

The unique architecture of rotaxanes and catenanes (as well as pseudorotaxanes see Volume III, Part 2, Chapter 6) lend themselves to the occurrence of large-amplitude motions by their component parts—a property reminiscent of the movements displayed by the working parts of machines in the macroscopic world. The concept of machine at the molecular level is not a new one. Our body can be looked upon as an extremely complex ensemble of molecular-level machines that power our movements, repair damage, and orchestrate our inner worlds of thought, sense, and emotion [69]. The challenge of constructing artificial molecular machines was posed for the first time by Feynman [70] in his famous address, There is Plenty of Room at the Bottom, to the American Physical Society in 1959. In his address, he raised a number of interesting issues, such as ...
