Life's Universal Scaling Laws
N 100 years ago, the eminent biologist D'Arcy Thompson began his wonderful book On Growth and Form iCamhridge U. Press, 1917) by quoting Immanue! Kant. The philosopher had observed that "chemistry. .. was a science but not Science . . . for that the criterion of true Science lay in its relation to mathematics." Thompson then declared that, since a "mathematical chemistry" now existed, chemistry...
متن کاملScaling Laws in Turbulence∗
The largely open problem of scaling laws in fully developed turbulence is discussed, with the stress put on similarities and differences with scaling in field theory. A soluble model of the passive advection is examined in more detail in order to illustrate the principal ideas. 1 LANGEVIN VERSUS NAVIER-STOKES Many dynamical problems in physics may be described by evolution equations of the type...
متن کاملScaling Laws For Macrodispersion
Scaling laws for the macrodispersivity of ow through porous media are derived from the assumed scaling properties of geological heterogeneity. If is the exponent characterizing uid scaling and is the exponent which characterizes geological heterogeneity, then a simple scaling relation is = maxfa2 ; 1 a2 g. Typically, 0 < < 1, and 12 < < 1, leading to an anomalous, or scale dependent, di usion p...
متن کاملScaling Laws in Robotics
Scaling laws are pervasive in biological systems, found in a large number of life processes, and across 27 orders of magnitude. Recent findings show both biological and engineered motors adhering to two fundamental regimes for the mass scaling of maximum force output. This scaling law is of particular interest for the robotics field as it can affect the design stage of a robot. In this study we...
متن کاملScaling Laws in MHD Turbulence
We analyze the decay laws of the kinetic and magnetic energies and the evolution of correlation lengths in freely decaying incompressible magnetohydrodynamic (MHD) turbulence. Scale invariance of MHD equations assures that, in the case of constant dissipation parameters (i.e. kinematic viscosity and resistivity) and null magnetic helicity, the kinetic and magnetic energies decay in time as E ∼ ...
