Screen readers for accessibility

Screen readers are a form of assistive technology for people with disabilities. A list of screen readers is available including a section, Software aids for people with reading difficulties.

Reader software examples include Spoken Web, JAWS, and NonVisual Desktop Access (NVDA). In addition, Fangs screen reader emulator is an open-source extension for the Pale Moon browser that simulates how a web page would look in JAWS.

Oblique shock
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.
