# gst-ethno-lang: the physics of bubbles to describe (and to predict) the dynamics of linguistic patterns

<< If you want to know where you'll find dialects and why, a lot can be predicted from the physics of bubbles and our tendency to copy others around us >> James Burridge

Physics of bubbles could explain language patterns. July 24, 2017

https://m.phys.org/news/2017-07-physics-language-patterns.html

<< The model shows that the boundaries of language dialect regions are controlled by a length minimizing effect analogous to surface tension, mediated by variations in population density which can induce curvature, and by the shape of coastline or similar borders >>

<< The model is able to reproduce observations and predictions of dialectologists. These include dialect continua, isogloss bundling, fanning, the wavelike spread of dialect features from cities, and the impact of human movement on the number of dialects that an area can support >>

# behav: large-eared bats adopting slow-flight feeding strategies

AA << compare quantitative aerodynamic measures of flight efficiency of two bat species, one large-eared (Plecotus auritus) and one small-eared (Glossophaga soricina), flying freely in a wind tunnel >>

AA << find that the body drag of both species is higher than previously assumed and that the large-eared species has a higher body drag coefficient, but also produces relatively more ear/body lift than the small-eared species >>

<< The relatively higher power of the large-eared species results in lower optimal flight speeds and [AA] findings support the notion of a trade-off between the acoustic benefits of large external ears and aerodynamic performance. The result of this trade-off would be the eco-morphological correlation in bat flight, with large-eared bats generally adopting slow-flight feeding strategies >>

# behav: a new dead leaf camouflage strategy with orange spots and unexpected preserved resonance (T. spurioculis)

AA << study the wing mechanics and resonances of Typophyllum spurioculis, a new species of leaf-mimic katydid >>

<< This species performs an unusual laterally directed aposematic display, showing orange spots that simulate eyes at the leg base. At night, males are conspicuous by their loud, audible calling songs, which exhibit two spectral peaks at ca. 7 and 12 kHz >>

AA << find the effective sound radiators of the wings (speculae) vibrate with three modes of vibration, two of which include the frequencies observed in the calling song. Remarkably, this resonance is preserved in the parts of the wings mimicking necrotic leaves, which are in theory not specialised for sound production >>
