[79], Kammen (1990) and Drake (2011) say Franklin's Observations concerning the Increase of Mankind (1755) stands alongside Ezra Stiles' "Discourse on Christian Union" (1760) as the leading works of eighteenth-century Anglo-American demography; Drake credits Franklin's "wide readership and prophetic insight. A new module system has been introduced, and systems for exception handling are now standardized. [108] This essay in praise of chess and prescribing a code of behavior for the game has been widely reprinted and translated. He attended Boston Latin School but did not graduate; he continued his education through voracious reading. R5RS Scheme provides the predicates input-port? [83], As deputy postmaster, Franklin became interested in the North Atlantic Ocean circulation patterns. Benjamin's father and all four of his grandparents were born in England. R6RS[9] features a standard module system, allowing a split between the core language and libraries. Franklin sent them to America, where they escalated the tensions. In calling the procedure "+" to add 1 and 2, the expressions (ev +), (ev 1) and (ev 2) may be evaluated in any order, as long as the effect is not as if they were evaluated in parallel. 80–81. The reason for this confusion is that in Scheme with its lexical scoping the result of evaluating an expression depends on where it is evaluated. The Junto was a discussion group for issues of the day; it subsequently gave rise to many organizations in Philadelphia. Scheme inherits its block structure from earlier block structured languages, particularly ALGOL. "1782: Original Design of the Great Seal of the United States". Where the constant representing the boolean value of true is T in most Lisps, in Scheme it is #t. In Scheme the primitive datatypes are disjoint. Many of the SRFIs are supported by all or most Scheme implementations. Sletcher, Michael. In the R5RS standard, Scheme implementations are not required to implement the whole numerical tower, but they must implement "a coherent subset consistent with both the purposes of the implementation and the spirit of the Scheme language" (R5RS sec. [243][244] In 1728, aged 22, Franklin wrote what he hoped would be his own epitaph: The Body of B. Franklin Printer; Like the Cover of an old Book, Its Contents torn out, And stript of its Lettering and Gilding, Lies here, Food for Worms. [186], Franklin formulated a presentation of his beliefs and published it in 1728. Instead, he would work on one and only one each week "leaving all others to their ordinary chance." [45] Programming Design Paradigms,[46] a mandatory course for the Computer science Graduate Students at Northeastern University, also extensively uses Scheme. He married his first wife, Anne Child, in about 1677 in Ecton and emigrated with her to Boston in 1683; they had three children before emigration, and four after. [87][88] In 1853, the oceanographer and cartographer Matthew Fontaine Maury noted that while Franklin charted and codified the Gulf Stream, he did not discover it: Though it was Dr. Franklin and Captain Tim Folger, who first turned the Gulf Stream to nautical account, the discovery that there was a Gulf Stream cannot be said to belong to either of them, for its existence was known to Peter Martyr d'Anghiera, and to Sir Humphrey Gilbert, in the 16th century. Benjamin Franklin to Richard Price, October 9, 1780. The body may be repeated as desired by calling the procedure. Franklin, Printer. make-rectangular, make-polar, real-part, imag-part, magnitude, angle, complex? (R6RS sec 7.1)[9] Because of this, redefinition of standard procedures by mutation is forbidden. Prior to R5RS, Scheme had no standard equivalent of the eval procedure which is ubiquitous in other Lisps, although the first Lambda Paper had described evaluate as "similar to the LISP function EVAL"[19] and the first Revised Report in 1978 replaced this with enclose, which took two arguments. Ferroelectric memory has been substantially researched for several decades as its potential to obtain higher speed, lower power consumption, and longer endurance compared to conventional flash memory. [90], On October 21, 1743, according to the popular myth, a storm moving from the southwest denied Franklin the opportunity of witnessing a lunar eclipse. [citation needed], Among his associates in France was Honoré Gabriel Riqueti, comte de Mirabeau—a French Revolutionary writer, orator and statesman who in early 1791 would be elected president of the National Assembly. But the Work shall not be wholly lost: For it will, as he believ'd, appear once more, In a new & more perfect Edition, Corrected and Amended By the Author. Benjamin Franklin's father, Josiah Franklin, was a tallow chandler, soaper, and candlemaker. Franklin noted of him that "all the plausible behaviour I have described is meant only, by patting and stroking the horse, to make him more patient, while the reins are drawn tighter, and the spurs set deeper into his sides. [232], Franklin also declared the consumption of meat to be "unprovoked murder". An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco–American relations. They lived in a home in the Parisian suburb of Passy, donated by Jacques-Donatien Le Ray de Chaumont, who supported the United States. Her own husband had recently died, and she declined Franklin's request to marry her daughter. "[136], While living in London in 1768, he developed a phonetic alphabet in A Scheme for a new Alphabet and a Reformed Mode of Spelling. [60] After having prepared several turkeys this way, Franklin noted that "the birds kill'd in this manner eat uncommonly tender. are provided. [citation needed] After his return to the United States in 1775, Franklin became the Society's Corresponding Member, continuing a close connection. A new language standardization process began at the 2003 Scheme workshop, with the goal of producing an R6RS standard in 2006.
