movements towards acceleration startups have overcome two major difficulties: Dissemi-nation of the innovation virus in the academy and get enough critical mass of brain and resources. How long does it take to change the order of magnitude of the production of a new material from milligrams to tons? A Ph

Network goods exhibit positive consumption externalities, commonly known as "network externalities." In markets, this fact can give rise to the existence of a critical mass point, that is, a minimum network size that can be sustained in equilibrium, given the cost and market structure

The aim of this paper is to determine and forecast the timing and level of critical mass in the development of market penetration for wireless communications. We assume that critical mass is fulfilled at the point when the acceleration of the diffusion process is at its maximum. In practice

Remarks on the blow-up for the Schrödinger

We recall the generalization of the Feynman-Metropolis-Teller approximation for a compressed atom using a relativistic Fermi-Thomas model. These results within a Wigner-Seitz approximation lead to a new equation of state for white dwarfs and to a new value of their critical mass, smaller than

Abstract It is widely speculated that the adoption of a technology takes off to be self-sustaining if it reaches the critical mass. However, the sponsors of competing technologies may engage in strategic manoeuvring in the adoption process. Indeed, it will be shown that in the de facto

Abstract – The OB-1 method for the calculation of the minimum critical mass of fissile actinides in metal/water systems was described in a previous paper. A fit to the calculated minimum critical mass data using the extended criticality parameter is the basis of the revised method. The solution

network, an intermediate size that is unstable, and a large stable and Pareto optimal one. We expect that the market will select the largest of the three equilibrium networks. As a result, small networks will not observed. We call critical mass the size of the smallest network that can be supported
