Polygraph (duplicating device)A polygraph is a duplicating device that produces a copy of a piece of writing simultaneously with the creation of the original, using pens and ink. Patented by John Isaac Hawkins on May 17, 1803, it was most famously used by the third U.S. president, Thomas Jefferson, who acquired his first polygraph in 1804 and later suggested improvements to Charles Willson Peale, owner of the American rights.Signature
PantographA pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from its original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces mimic movements recorded by a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen or stylus fixed to the other.
Plausible deniabilityPlausible deniability is the ability of a person or organization to deny a connection (knowledge, responsibility, or involvement) to a controversial action in a manner that cannot be conclusively disproved. In politics and espionage, the term traditionally refers to the concealment or withholding of acknowledgement, of a sponsor's role in a covert operation, so that the sponsoring government can disclaim responsibility if the operation comes to light.
Poly(methyl methacrylate)Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic used as an engineering plastic. PMMA is also known as acrylic and acrylic glass and by the trade names and brands Crylux, Walcast, Wanjiale, Hesalite, Plexiglas, Acrylite, Lucite, PerClax, and Perspex, among several others (see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass.
ProvenanceProvenance (from French'to come from/forth') is the chronology of the ownership, custody or location of a historical object. The term was originally mostly used in relation to works of art, but is now used in similar senses in a wide range of fields, including archaeology, paleontology, archival science, economy, computing, and scientific enquiry in general.
Cartesian coordinate systemIn geometry, a Cartesian coordinate system (UK: , US: ) in a plane is a coordinate system that specifies each point uniquely by a pair of real numbers called coordinates, which are the signed distances to the point from two fixed perpendicularoriented lines, called coordinate lines, coordinate axes or just axes (plural of axis) of the system. The point where the axes meet is called the origin and has (0, 0) as coordinates. The axes directions represent an orthogonal basis.
AutographAn autograph is a person's own handwriting or signature. The word autograph comes from Ancient Greek (αὐτός, autós, "self" and γράφω, gráphō, "write"), and can mean more specifically: a manuscript written by the author of its content. In this meaning the term autograph can often be used interchangeably with holograph. a celebrity's handwritten signature. Autograph collecting is the activity of collecting such autographs.Profile (engineering)
FacsimileA facsimile (from Latinfac simile, "to make alike") is a copy or reproduction of an old book, manuscript, map, art print, or other item of historical value that is as true to the original source as possible. It differs from other forms of reproduction by attempting to replicate the source quite accurately in scale, color, condition, and other material qualities.
Matrix (printing)In the manufacture of metal type used in letterpress printing, a matrix (from the Latin meaning womb or a female breeding animal) is the mould used to cast a letter, known as a sort. Matrices for printing types were made of copper. However, in printmaking the matrix is whatever is used, with ink, to hold the image that makes up the print, whether a plate in etching and engraving, a stone or plate in lithography, or a woodblock in woodcut.*As an Amazon Associate I earn from qualifying purchases.
