Sound

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.

Acoustics

Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an acoustician, while someone working in the field of acoustical engineering may be called an acoustical engineer. An audio engineer, on the other hand is concerned with the recording, manipulation, mixing, and reproduction of sound.

Applications of acoustics are found in almost all aspects of modern society, subdisciplines include aeroacoustics, audio signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, psychoacoustics, speech, ultrasound, underwater acoustics, and vibration.

Color

Color (American English) or colour (Commonwealth English) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space colors can be identified numerically by their coordinates.

Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.

The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).

Toy Story

Toy Story is a 1995 American computer-animated buddy-comedy adventure film produced by Pixar Animation Studios and released by Walt Disney Pictures. Directed by John Lasseter, Toy Story was the first feature-length computer-animated film and the first theatrical film produced by Pixar. Toy Story follows a group of anthropomorphic toys who pretend to be lifeless whenever humans are present, and focuses on the relationship between Woody, a pullstring cowboy doll (voiced by Tom Hanks), and Buzz Lightyear, an astronaut action figure (voiced by Tim Allen). The film was written by John Lasseter, Andrew Stanton, Joel Cohen, Alec Sokolow, and Joss Whedon, and featured music by Randy Newman. Its executive producers were Steve Jobs and Edwin Catmull.

Pixar, which produced short animated films to promote their computers, was approached by Disney to produce a computer-animated feature after the success of the short film, Tin Toy (1988), which is told from a small toy's perspective. Lasseter, Stanton, and Pete Docter wrote early story treatments which were thrown out by Disney, who pushed for a more edgy film. After disastrous story reels, production was halted and the script was re-written, better reflecting the tone and theme Pixar desired: that "toys deeply want children to play with them, and that this desire drives their hopes, fears, and actions." The studio, then consisting of a relatively small number of employees, produced the film under minor financial constraints.

Hot Wheels

Hot Wheels is a brand of 1:64, 1:43, 1:18 and 1:50 scale die-cast toy cars introduced by American toy maker Mattel in 1968. It was the primary competitor of Matchbox until 1997 when Mattel bought Tyco Toys, then-owner of Matchbox. Many automobile manufacturers have licensed Hot Wheels to make scale models of their cars, allowing the use of original design blueprints and detailing. Although Hot Wheels were originally intended for children and young adults, they have become popular with adult collectors, for whom limited edition models are now made available.

History

1968

Hot Wheels were conceived to be more like "tricked out" cars as compared to Matchbox cars which were more city or "real life" cars. There were sixteen castings released in 1968, eleven of them designed by Harry Bentley Bradley. The first one produced was a dark blue Custom Camaro. Bradley was from the car industry and had designed the body for the (full-sized) Dodge Deora concept car and the Custom Fleetside, (based on his own customized 1968 Chevrolet C-10 Fleetside).
