Coucher de soleil no. 1 sphere, also called Poincaré dodecahedral space, is a particular example of a homology sphere. Being a spherical 3-manifold, it is the only homology 3-sphere, besides the 3-sphere itself, with a finite fundamental group. While it is not known the extent to which such discoveries influenced Metzinger's representation of the radiating sun in "Coucher de soleil no. 1", his interest and prowess in mathematics is well documented. Coucher de soleil no. 1 Coucher de soleil no. 1 (also called Landscape, Paysage, Landschap, or Sunset No. 1) is an oil painting created circa 1906 by the French artist and theorist Jean Metzinger
Sun Language Theory Sun Language Theory The Sun Language Theory () was a Turkish nationalist pseudoscientific linguistic hypothesis developed in Turkey in the 1930s that proposed that all human languages are descendants of one proto-Turkic primal language. The theory proposed that because this primal language had close phonemic resemblances to Turkish, all other languages can essentially be traced back to Turkic roots. According to the theory, the Central Asian worshippers, who wanted to salute the omnipotence of the sun and its life-giving qualities, had done so by transforming their meaningless blabbering into a coherent set of ritual utterings, and language was born, hence
