Convex lenses produce an image of an object at infinity at their focus ; if the sun is imaged, much of the visible and infrared light incident on the lens is concentrated into the small image.

The earliest known citation on the Internet is from 1986 on Usenet in the signature of a poster from Convex Computer Corporation as "' I think there is a world market for about five computers ' — Remark attributed to Thomas J. Watson ( Chairman of the Board of International Business Machines ), 1943 ".

Convex quadratic programming is a special case of the more general field of convex optimization.

There is a mailing list of Convex ex-employees, as well as frequent reunions.

In order to lower costs, the Convex designs were not as technologically aggressive as Cray's, and were based on more mainstream chip technology, attempting to make up for the loss in performance in other ways.

Convex had an unusually thorough interview process, which, for technical positions, included a grilling by a group of engineers.

* Pulitzer Prize for Poetry: John Ashbery, Self-Portrait in a Convex Mirror

Among the most respected of the postwar American poets are John Ashbery, the key figure of the surrealistic New York School of poetry, and his celebrated Self-portrait in a Convex Mirror ( Pulitzer Prize for Poetry, 1976 ); Elizabeth Bishop and her North & South ( Pulitzer Prize for Poetry, 1956 ) and " Geography III " ( National Book Award, 1970 ); Richard Wilbur and his Things of This World, winner of both the Pulitzer Prize and the National Book Award for Poetry in 1957 ; John Berryman and his The Dream Songs, ( Pulitzer Prize for Poetry, 1964, National Book Award, 1968 ); A.

Marshall founded the website HowStuffWorks. com in 1998 and ran the site until 2002, when he sold it to The Convex Group, an Atlanta-based investment company owned by former Web MD CEO Jeff Arnold, for around $ 1 million.

In 2007, Convex sold it to Discovery Communications for $ 250 million.
