Breathtaking “Cloud Tsunami” Rolls Over Sydney


 Last Friday, a “cloud tsunami” startled the residents of New South Wales, Australia. Technically a “shelf cloud,” those on Bondi Beach saw what appeared to be a massive, several-kilometer-long wave stretching across the sky. The Australian Bureau of Meteorology issued warnings to the surrounding areas due to thunderstorms, heavy rains, and strong winds.
“[The shelf cloud] is created by a cold outflow from a thunderstorm lifting the moist air very abruptly, it is an outflow feature from a thunderstorm,” forecaster Christopher Webb explained to The Daily Telegraph. “When the rain from the thunderstorm comes vertically down it drags the air with it, it spreads horizontally and forms a gust front, you get the humid air being lifted abruptly from the outflow of the thunderstorm.”

16 Stunning Works Of Origami Art To Celebrate World Origami Day

 November 11 is Origami Day in Japan, where the paper crane has become a symbol of peace, but did you know that Origami isn’t an entirely Japanese invention?
Ancient Japanese origami used cut or marked paper, and was first mentioned in a poem from 1680. In Europe 100 years later, German pedagogue Friedrich Fröbel taught kindergarten children simple mathematical forms by folding whole pieces of paper. This system was imported to Japan after 1860, and is the basis for what we consider modern origami.
