Word Origin & History

J 
the letter is a late modification of Roman -i-, originally a scribal creation in continental M.L. to distinguish small -i- in cursive writing from the strokes of other letters, especially in the final positions of words. But in Eng., -y- was used for this, and -j- was introduced c.1600-1640 to take up the consonantal sound that had evolved from -i- since L.L. times. This usage first was attested in Sp., where it was in place before 1600. Eng. dictionaries continued to lump together words beginning in -i- and -j- until 19c.

joule 
"unit of electrical energy," 1882, coined in recognition of British physicist James P. Joule (1818-89).

Main Entry: J
Function: symbol
mechanical equivalent of heat

Main Entry: joule
Pronunciation: 'jü(&)l
Function: noun
: a unit of work or energy equal to the work done by a force of one newton acting through adistance of one meter
Joule, James Prescott (1818–1889), British physicist. Joule is famous for his experiments on heat. In a series of investigations he demonstratedthat heat is a form of energy (regardless of the substance that is heated) and later determined quantitatively the amount of mechanical and electrical energy expended in the generation of heat energy.In 1843 he published his value for the amount of work required to produce a unit of heat, now known as the mechanical equivalent of heat. He established the principle that various forms of energy— mechanical, electrical, and heat — are basically the same and are interchangeable. This principle forms the basis of conservation of energy. The joule unit of work or energy was named inhis honor in 1882.

J
A derivative and redesign of APL with added features and control structures. J is purely functional with lexical scope and more conventional control structures, plus several new concepts such as function rank and function arrays. J was designed and developed by Kennneth E. Iverson and Roger Hui . J uses only the ASCII character set but has a spelling scheme that retains the advantages of APL's special alphabet. J is a conventional procedural programming language but can be used as a purely functional language.
Version 4.1 for MS-DOS, Sun, Mac, Archimedes. Source available in C from Iverson Software, +1 (416) 925 6096.
Version 6 package from ISI includes an interpreter and tutorial. Ported to DEC, NeXT, SGI, Sun-3, Sun-4, Vax, RS/6000, MIPS, Macintosh, Acorn Archimedes, IBM PC, Atari, 3b1, Amiga.
