The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions, and internal ...
1887 – Pierre Henri Hugoniot based on the work of Rankine, introduces the Rankine–Hugoniot conditions to model shock waves. 1887 – First models of supersonic waves by Ernst Mach. [39] He introduces the concept of Mach number. 1888 – First commercial Venturi tube by Clemens Herschel.
Pyramid decoupage (also called pyramage) is a process similar to 3D decoupage. In pyramid decoupage, a series of identical images are cut into progressively smaller, identical shapes which are layered and fixed with adhesive foam spacers to create a 3D "pyramid" effect. A person who does decoupage is known as a decoupeur, or "cutter".
The early technological and industrial development in the United States was facilitated by a unique confluence of geographical, social, and economic factors. The relative lack of workers kept U.S. wages generally higher than salaries in Europe and provided an incentive to mechanize some tasks.
1738 — Daniel Bernoulli asserted in Hydrodynamica the principle that as the speed of a moving fluid increases, the pressure within the fluid decreases. ( Kinetic theory ) 1742 — Anders Celsius proposed a temperature scale in which 100 represented the temperature of melting ice and 0 represented the boiling point of water at 25 inches and 3 ...
1962 – Henry Geldzahler, curator of 20th-century art at the Metropolitan Museum of Art, took Robert Rauschenberg to Andy Warhol's studio; Warhol showed the visiting artist how he made art from screen prints. Rauschenberg then used screen printing soon after that in his 1962 work Crocus, to transfer an image in black ink.
Collage. Collage (/ kəˈlɑːʒ /, from the French: coller, "to glue" or "to stick together"; [1]) is a technique of art creation, primarily used in the visual arts, but in music too, by which art results from an assemblage of different forms, thus creating a new whole. (Compare with pastiche, which is a "pasting" together.)
As a result, book-sized computers of today can outperform room-sized computers of the 1960s, and there has been a revolution in the way people live – in how they work, study, conduct business, and engage in research. World War II had a profound impact on the development of science and technology in the United States.
