Dots and boxes is a pencil-and-paper game for two players (sometimes more). It was first published in the 19th century by French mathematician Édouard Lucas , who called it la pipopipette . [ 1 ] It has gone by many other names, [ 2 ] including dots and dashes , game of dots , [ 3 ] dot to dot grid , [ 4 ] boxes , [ 5 ] and pigs in a pen .
Detail from Seurat's Parade de cirque, 1889, showing the contrasting dots of paint which define Pointillism. Pointillism (/ ˈ p w æ̃ t ɪ l ɪ z əm /, also US: / ˈ p w ɑː n-ˌ ˈ p ɔɪ n-/) [1] is a technique of painting in which small, distinct dots of color are applied in patterns to form an image.
Chart of the Morse code 26 letters and 10 numerals [1]. This Morse key was originally used by Gotthard railway, later by a shortwave radio amateur [2]. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs.
In Czech, the mnemonic device to remember letters in Morse code lies in remembering words or short phrases that begin with each appropriate letter and have a long vowel (i.e. á é í ó ú ý) for every dash and a short vowel (a e i o u y) for every dot. Additionally, some other sets of words with a particular theme have been thought up in ...
However, the box tally and dot-and-dash tally characters were not accepted for encoding, and only the five ideographic tally marks (正 scheme) and two Western tally digits were added to the Unicode Standard in the Counting Rod Numerals block in Unicode version 11.0 (June 2018). Only the tally marks for the numbers 1 and 5 are encoded, and ...
In the early 2000s, while living in New York City and New Mexico, Benefiel created the "Random Numeric Repeater" series of ink and watercolour on paper using what he described as a "dumb language", a random sequence of dots, circles, and dashes. Each symbol represents a corresponding numeral and sound that he made when creating the drawings.
As already mentioned, American Morse is less suitable for use on cables because of the high density of dots. However, this same feature, together with the shorter dash, leads to the advantage of a more compressed code and a faster sending rate. The same operator could send at least 20% faster with American Morse than with International Morse. [6]
a Wright Brothers telegraph key (missing its knob) A Morse Key from G. Hasler, Bern (1900) first used by Gotthard Railway A telegraph key, clacker, tapper or morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. [1]
