I am a teenage boy living in Pennsylvania. I like to read and mess around with computer stuff, especially Wikipedia. I am also a Boy Scout.
I heartily support placing stub templates on pages; I'm sick of clicking "random article" and getting an article with two lines! Often, I have the list of stubs up in a different tab.
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.
