A copy made with carbon paper. Before the development of photographic copiers, a carbon copy was the under-copy of a typed or written document placed over carbon paper and the under-copy sheet itself (not to be confused with the carbon print family of photographic reproduction processes). [1]

There have been some experimental uses of carbon paper in art: as a surface for painting and mail art (to decorate envelopes). Carbon paper is commonly used to transfer patterns onto glass in the creation of stained glass. [7] Carbon paper disks are still used in school physics labs as part of experiments on projectile motion and position. [8]
Chester Floyd Carlson (February 8, 1906 – September 19, 1968) was an American physicist, inventor, and patent attorney born in Seattle, Washington.. Carlson invented electrophotography (now xerography, meaning "dry writing"), producing a dry copy in contrast to the wet copies then produced by the Photostat process; it is now used by millions of photocopiers worldwide.
Carbonless copying provides an alternative to the use of carbon copying. Carbonless copy paper has micro-encapsulated dye or ink on the back side of the top sheet, and a clay coating on the front side of the bottom sheet. When pressure is applied (from writing or impact printing), the dye capsules rupture and react with the clay to duplicate ...
CC, for "CopyCat" or "Carbon Copy" [1] (December 22, 2001 – March 3, 2020), was a brown tabby and white domestic shorthair and the first cloned pet. [2] She was cloned by scientists at Texas A&M University in conjunction with Genetic Savings & Clone Inc. CC's surrogate mother was a tabby, but her genetic donor, Rainbow, was a calico domestic ...
Carbon Copy was "a remote control/communications program" [1] with for-its-day advanced features for remote screen sharing, [2] background file transfer, and "movable chat windows". [ 3 ] Overview
In physics, the observer effect is the disturbance of an observed system by the act of observation. [1] [2] This is often the result of utilising instruments that, by necessity, alter the state of what they measure in some manner. A common example is checking the pressure in an automobile tire, which causes some of the air to escape, thereby ...
