We call an idea "alive" in a human community of N individuals, if at least one of them accepts it. Such an individual will create "copies" of this idea; any such free-floating copy has a probability to be accepted by any other individual. In this way

Is it not sheer foolishness to try to apply the methods of theoretical physics to biological structures? Physics flowered because it limited itself to the study of very simple systems; on the other hand, the essence of'living things'seems to have to

For a 2-dimensional Brownian motion ω ( t ) starting from x 0 at t = 0 and for a given function V ( x ), x ∈ R 2 , we determine (i) a normalization factor ν( T ) such that the random variable, \(X[\mathbf{\omega}] = \lim_{T \to \infty} \nu(T)^{-1

We present and analyze a model of the frequency of severe terrorist attacks, which generalizes the recently proposed model of Johnson et al. This model, which is based on the notion of self-organized criticality and which describes how terrorist cell

The motion in the plane of an harmonically bound charged particle interacting with a magnetic field and a half-plane barrier along the positive x-axis is studied. The magnetic field is perpendicular to the plane in which the particle moves. This moti

We consider the long lived pool of B and T cells that recirculate through blood, tissues and the lymphatic system of an animal with body mass M. We derive scaling rules (allometric relations) for: (1) the rate of production of mature lymphocytes; (2)

We discuss two simple quantitative models for: (1) Richardson's law for the distribution of the size of wars; (2) The distribution of the size of severe terrorist attacks. In both cases the models predict power law exponents that are consistent with
