Not an enchanted place.
I was once asked to take on a new patient by her husband. He came expecting to be turned down because he had been told by others that his request was unreasonable. His once-well wife needed to be in a chronic care setting, but she wanted to live at home. And he wanted her at home too. He needed a physician to organize her home care. I agreed to take her on in my practice, and we started to put ...
متن کاملThe insidiously enchanted forrest
Scientific Representation: Paradoxes of Perspective (henceforth: Representation), B.C. van Fraassen’s most recent, 400 page contribution to the philosophy of science, is contemporary, varied, systematic, historical, exciting, provocative, empiricist, pragmatist, profound, sometimes sketchy and accessible. We ground these judgments subsequently whilst treating most of the topics of Representatio...
متن کاملA simple self-organized swimmer driven by molecular motors
We investigate a self-organized swimmer at low Reynolds numbers. The microscopic swimmer is composed of three spheres that are connected by two identical active linker arms. Each linker arm contains molecular motors and elastic elements and can oscillate spontaneously. We find that such a system immersed in a viscous fluid can self-organize into a state of directed swimming. The swimmer provide...
متن کاملA Dickensian origin for Sherrington's enchanted loom?
Sherrington's image of the mind-brain as an 'enchanted loom' has intrigued scientists for decades. Its origin, however, has been unclear. Here, we make a new suggestion as to where it may have come from. The article sheds light on the connections between literary and scientific similes and metaphors.
متن کاملActive temperature and velocity correlations produced by a swimmer suspension.
The agitation produced in a fluid by a suspension of microswimmers in the low Reynolds number limit is studied. In this limit, swimmers are modeled as force dipoles all with equal strength. The agitation is characterized by the active temperature defined, as in kinetic theory, as the mean square velocity, and by the equal-time spatial correlations. Considering the phase in which the swimmers ar...
