The Last Scientific Revolution

Critically growing problems of fundamental science organisation and content are analysed with examples from physics and emerging interdisciplinary fields. Their origin is specified and new science structure (organisation and content) is proposed as a unified solution

Cycles in the Multiverse

Eternal inflation is a seemingly generic consequence of theories that give rise to accelerated expansion of the universe and possess multiple vacuum states. Making predictions in an eternally inflating universe is notoriously difficult because one must compare infinite quantities, and a wide variety of regulating procedures yield radically different results. This is the measure problem of eternal inflation. In this paper, we analyze models of eternal inflation which allow for the possibility of cyclic bubble universes: in each bubble, standard cosmological evolution is re-played over and over again. Eternal inflation can generically arise in cyclic models that include a dark energy dominated phase. In such models, several problematic consequences of standard regulating procedures, such as the youngness and Boltzmann Brain problems, are substantially alleviated. We discuss the implications for making predictions in cyclic models, as well as some general implications for understanding the measure problem in eternal inflation.Comment: 22 pages and 8 figure

Pluralism, the Lucas critique, and the integration of macro and micro

Mainstream macroeconomics has pursued .micro founded.models based on the explicit optimization by representative agents. The result has been a long and wasteful detour. But elements of the Lucas critique are relevant, also for heterodox economists. Challenging common heterodox views on microeconomics and formalization, this paper argues that (i) economic models should not be based purely on empirically observed regularities,(ii) heterodox economists must be able to tell an integrated story about goal-oriented micro behavior in a specific macro environment, and (iii)relatively simple analytical models have an essential role to play.

James and Whitehead: Assemblage and Systematization of a Deeply Empiricist Mosaic Philosophy

This paper contributes to a growing body of philosophical and psychological work that draws parallels between the writings of William James and Alfred North Whitehead. In Part One I introduce Whitehead’s distinction between assemblage and systematization (section 1) and suggest that Whitehead’s philosophy was in part a systematization of James’ psychological and philosophical assemblage (section 2). The systematization is based on a rethinking of the entity/function contrast (section 3) by way of Whitehead’s concept of the actual entity/occasion (section 4). This permits a process-oriented ontological extension and James’ notion of pure experience (sections 5 & 6), which yields a deepened version of radical empiricism (section 7). The four sections of Part Two build a more specific argument that James’ often implicit distinctions between energetic, perceptual, conceptual and discursive modes of experience can be systematized by way of Whitehead’s concepts of causal efficacy, presentational immediacy and symbolic reference. Following the suggestion of Magritte’s famous Ceci n’est pas une Pipe artwork, this yields an analysis of the sum of human experience into four progressively integrated factors: power, image, proposition and enunciation

Unreduced Dynamic Complexity: Towards the Unified Science of Intelligent Communication Networks and Software

Operation of autonomic communication networks with complicated user-oriented functions should be described as unreduced many-body interaction process. The latter gives rise to complex-dynamic behaviour including fractally structured hierarchy of chaotically changing realisations. We recall the main results of the universal science of complexity (http://cogprints.org/4471/) based on the unreduced interaction problem solution and its application to various real systems, from nanobiosystems (http://cogprints.org/4527/) and quantum devices to intelligent networks (http://cogprints.org/4114/) and emerging consciousness (http://cogprints.org/3857/). We concentrate then on applications to autonomic communication leading to fundamentally substantiated, exact science of intelligent communication and software. It aims at unification of the whole diversity of complex information system behaviour, similar to the conventional, "Newtonian" science order for sequential, regular models of system dynamics. Basic principles and first applications of the unified science of complex-dynamic communication networks and software are outlined to demonstrate its advantages and emerging practical perspectives
