Why chaotic mixing of particles is inevitable in the deep lung.

Fine/ultrafine particles can easily reach the pulmonary acinus, where gas is exchanged, but they need to mix with alveolar residual air to land on the septal surface. Classical fluid mechanics theory excludes flow-induced mixing mechanisms because of the low Reynolds number nature of the acinar flow. For more than a decade, we have been challenging this classical view, proposing the idea that c...

Chaotic mixing deep in the lung.

Our current understanding of the transport and deposition of aerosols (viruses, bacteria, air pollutants, aerosolized drugs) deep in the lung has been grounded in dispersive theories based on untested assumptions about the nature of acinar airflow fields. Traditionally, these have been taken to be simple and kinematically reversible. In this article, we apply the recently discovered fluid mecha...

Why a World State is Inevitable

Long dismissed as unscientific, teleological explanation has been undergoing something of a revival as a result of the emergence of selforganization theory, which combines micro-level dynamics with macrolevel boundary conditions to explain the tendency of systems to develop toward stable end-states. On that methodological basis this article argues that a global monopoly on the legitimate use of...
