The first sheet can be typed, drawn, or written upon. The second sheet is coated with a layer of wax that had been impregnated with one of a variety of colorants. The pressure of writing or typing on the first sheet transfers the colored wax from the second sheet to the shiny, coated back side of the first sheet, producing a mirror image.
The word "page" comes from the Latin term pagina, which means, "a written page, leaf, sheet", [2] which in turn comes from an earlier meaning "to create a row of vines that form a rectangle". [3] The Latin word pagina derives from the verb pangere , which means to stake out boundaries when planting vineyards.
This formed the basis for W3Catalog, the web's first primitive search engine, released on September 2, 1993. [18] In June 1993, Matthew Gray, then at MIT, produced what was probably the first web robot, the Perl-based World Wide Web Wanderer, and used it to generate an index called "Wandex". The purpose of the Wanderer was to measure the size ...

The Jaccard index is a statistic used for gauging the similarity and diversity of sample sets. It is defined in general taking the ratio of two sizes (areas or volumes), the intersection size divided by the union size, also called intersection over union (IoU).
Then the distance between and is given by: [2] d ( p , q ) = ( p 1 − q 1 ) 2 + ( p 2 − q 2 ) 2 . {\displaystyle d(p,q)={\sqrt {(p_{1}-q_{1})^{2}+(p_{2}-q_{2})^{2}}}.} This can be seen by applying the Pythagorean theorem to a right triangle with horizontal and vertical sides, having the line segment from p {\displaystyle p} to q ...
