Colour distribution of a Newton disk. The Newton disk, also known as the disappearing color disk, is a well-known physics experiment with a rotating disk with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when it's spun rapidly about its axis.
The Multi Emulator Super System can run the Rainbow-specific Windows 1.0. The Rainbow 100 played a small but important role in the creation of the FidoNet system. A computer club in St. Louis was in the process of setting up a BBS system using CBBS on CP/M when they learned that DEC would be giving the club a Rainbow 100 for free. The group ...
Disc rot is the tendency of CD, DVD, or other optical discs to become unreadable because of chemical deterioration. The causes include oxidation of the reflective layer, reactions with contaminants, ultra-violet light damage, and de-bonding of the adhesive used to adhere the layers of the disc together.
Over most of the disc, scattered light at all wavelengths overlaps, resulting in white light which brightens the sky. At the edge, the wavelength dependence of the scattering gives rise to the rainbow. [5] The light of a primary rainbow arc is 96% polarised tangential to the arc. [6] The light of the second arc is 90% polarised.

A computer-generated image of an Airy disk. The grayscale intensities have been adjusted to enhance the brightness of the outer rings of the Airy pattern. A computer-generated Airy disk from diffracted white light (D65 spectrum). Note that the red component is diffracted more than the blue, so that the center appears slightly bluish.
A 130 mm 2.6 GB magneto-optical disc A 230 MB Fujitsu 90 mm magneto-optical disc. Early drives are 130 mm and have the size of full-height 130 mm hard-drives (like in the IBM PC XT ). 130 mm media looks similar to a CD-ROM enclosed in an old-style caddy , while 90 mm media is about the size of a regular 3 1 ⁄ 2 -inch floppy disk , but twice ...
