Non-Euclidean geometry in nature
, 2017 I describe the manifestation of the non-Euclidean geometry in the behavior of collective observables of some complex physical systems. Specifically, I consider the formation of equilibrium shapes of plants and statistics of sparse random graphs.

Language Learning, Volume 75, Issue 4, Page 1222-1256, December 2025.Abstract This study involved a three‐level meta‐analysis on the correlations between metalinguistic awareness (i.e., orthographic, phonological, and morphological awareness) and Chinese word reading. Based on 16,823 individuals from 81 studies, the results revealed moderate associations between all three metalinguistic skills and Chinese word reading ...

Inefficient star formation through turbulence, magnetic fields and feedback
, 2015 Star formation is inefficient. Only a few percent of the available gas in molecular clouds forms stars, leading to the observed low star formation rate (SFR). The same holds when averaged over many molecular clouds, such that the SFR of whole galaxies is
