An oblique shock is a shock wave that, unlike a normal shock, is inclined with respect to the direction of incoming air. It occurs when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. This photograph shows an oblique shock at the nose of a Northrop T-38 Talon aircraft, made visible through Schlieren photography. Photograph credit: NASA & US Air Force (J.T.

Zhou Fang was a Chinese painter during the Tang dynasty, living in the capital of Chang'an (modern Xi'an) during the 8th century. He came from a noble background and this was reflected in his works. He personally painted for the emperor and the themes of his artwork covered religious subjects and everyday life. This ink-and-color-on-silk painting, titled Court Ladies Playing Double-sixes, measures 30.5 cm × 69.1 cm (12.0 in × 27.2 in) and depicts members of the emperor's household playing the board game liubo. It now hangs in the Freer Gallery of Art in Washington, D.C. Painting credit: Zhou Fang

The green kingfisher (Chloroceryle americana) is a species of bird in the kingfisher family, Alcedinidae. It is found from the southern United States, south through Central America, and in every mainland South American country except Chile. The green kingfisher is about 20 cm (7.9 in) long and weighs about 35 to 40 g (1.2 to 1.4 oz), with females being larger and heavier than males. It has various vocalisations, including one described as resembling "the striking of two pebbles together" and another as "a harsh, buzzy scold". This male green kingfisher, a member of the subspecies C. a. americana, was spotted close to the Cristalino River in the Pantanal, Brazil. Photograph credit: Charles J. Sharp
