The Naive Physics Perplex
ion in physical reasoning. Approximation and abstraction in physical reasoning takes many forms: Objects of complex characteristics can be approximated by objects of simpler characteristics (for example, a real resistor by an ideal resistor or a curved object by a polyhedral object), a group of objects can be approximated by a single object (figure 10), and a group of simple objects can be appr...
متن کاملThe Naive Physics Perplex
The \Naive Physics Manifesto" of Pat Hayes (1978) proposes a large-scale project of developing a formal theory encompassing the entire knowledge of physics of naive reasoners, expressed in a declarative symbolic form. The theory is organized in clusters of closely interconnected concepts and axioms. More recent work in the representation of commonsense physical knowledge has followed a somewhat...

متن کاملBeware the Borg
newly determined structure of a filament-forming protein from bacteria is eerily similar to that of eukaryotic actin. The bacterial protein, MreB, was known to affect cell shape in bacteria; Escherichia coli that lack MreB are spherical rather than rod-shaped. In March of this year, Jeffery Errington and colleagues (University of Oxford, UK) reported that filamentous helical A Actin (left) and ...

Although typical morning glories are uniform in color {A, B), the insertion and excision of transposable genetic elements can cause variable "knockout" mutations in the gene for pigment production, resulting in variegated flowers (C through F). From Genes in Conflict. Analysis of output from the Human Genome Project makes it clear that just one form of such alien DNA, transposons, makes up abou...
