A new and universal method for implementing scale invariance, called best matching, is presented. It extends to scaling the method introduced by Bertotti and the author to create a fully relational dynamics that satisfies Mach's principle. The method is illustrated here in the context of non-relativistic gravitational particle dynamics. It leads to far(More)
The term selective inattention as used here subsumes those phenomena whose primary function is the active blocking or attenuation of partially processed contents en route to conscious expression. Examples are anxiety-motivated forgetting or perceptual distortion and hypnotically induced negative hallucinations. Studies in the field of selective attention(More)
We present a scale-invariant theory, conformal gravity, which closely resembles the geometro-dynamical formulation of general relativity (GR). While previous attempts to create scale-invariant theories of gravity have been based on Weyl's idea of a compensating field, our direct approach dispenses with this and is built by extension of the method of best(More)
According to reductionism, every complex phenomenon can and should be explained in terms of the simplest possible entities and mechanisms. The parts determine the whole. This approach has been an outstanding success in science, but this essay will point out ways in which it could nevertheless be giving us wrong ideas and holding back progress. For example ,(More)
With his aphorism 'it from bit', Wheeler argued that anything physical , any it, ultimately derives its very existence entirely from discrete detector-elicited information-theoretic answers to yes or no quantum binary choices: bits. In this spirit, many theorists now give ontological primacy to information. To test the idea, I identify three distinct kinds(More)
