Comparison of first and third-angle projections showing that related parts in the views are closer in third-angle. In first-angle projection, the object is conceptually located in quadrant I, i.e. it floats above and before the viewing planes, the planes are opaque, and each view is pushed through the object onto the plane furthest from it ...
Margaret Petherbridge Farrar (March 23, 1897 – June 11, 1984) was an American journalist and the first crossword puzzle editor for The New York Times (1942–1968). Creator of many of the rules of modern crossword design, she compiled and edited a long-running series of crossword puzzle books – including the first book of any kind that Simon & Schuster published (1924).

Cryptic crosswords often use abbreviations to clue individual letters or short fragments of the overall solution. These include: Any conventional abbreviations found in a standard dictionary, such as: "current": AC (for "alternating current"); less commonly, DC (for "direct current"); or even I (the symbol used in physics and electronics)
Orthographic projection (also orthogonal projection and analemma) [a] is a means of representing three-dimensional objects in two dimensions.Orthographic projection is a form of parallel projection in which all the projection lines are orthogonal to the projection plane, [2] resulting in every plane of the scene appearing in affine transformation on the viewing surface.
In 1950, the crossword became a daily feature. That first daily puzzle was published without an author line, and as of 2001 the identity of the author of the first weekday Times crossword remained unknown. [13] There have been four editors of the puzzle. Farrar edited the puzzle from its inception in 1942 until 1969.
A multiview projection is a type of orthographic projection that shows the object as it looks from the front, right, left, top, bottom, or back (e.g. the primary views), and is typically positioned relative to each other according to the rules of either first-angle or third-angle projection. The origin and vector direction of the projectors ...
