Frasi di Ada Lovelace
Ada Lovelace
Data di nascita: 10. Dicembre 1815
Data di morte: 27. Novembre 1852
Augusta Ada Byron, meglio nota come Ada Lovelace , è stata una matematica inglese, nota soprattutto per il suo lavoro alla macchina analitica ideata da Charles Babbage.
Tra i suoi appunti sulla macchina di Babbage si rintraccia anche un algoritmo per generare i numeri di Bernoulli, considerato come il primo algoritmo espressamente inteso per essere elaborato da una macchina, tanto che Ada Lovelace è spesso ricordata come la prima programmatrice di computer al mondo.Ada fu la sola figlia legittima del poeta Lord Byron e della matematica Anne Isabella Milbanke. Non conobbe il padre, che lasciò la famiglia quando lei non aveva ancora un anno di vita. Fin da giovane s'interessò alle scienze matematiche e in particolare al lavoro di Babbage sulla macchina analitica. Anche se la macchina di Babbage non fu mai costruita, gli studi della Lovelace sono importanti per la storia del computer. Ada Lovelace aveva previsto anche la capacità dei computer di andare al di là del mero calcolo numerico, mentre altri, incluso lo stesso Babbage, si focalizzavano soltanto su questa capacità.Il linguaggio di programmazione Ada, il cui sviluppo è stato finanziato dal Dipartimento della Difesa degli Stati Uniti, è così chiamato in suo onore.
Frasi Ada Lovelace
„God has not given to us (in this state of existence) more than very limited powers of expression of one's ideas and feelings“
Contesto: Circumstances have been such, that I have lived almost entirely secluded for some time. Those who are much in earnest and with single minds devoted to any great object in life, must find this occasionally inevitable.... You will wonder at having heard nothing from me; but you have experience and candour enough to perceive and know that God has not given to us (in this state of existence) more than very limited powers of expression of one's ideas and feelings... I shall be very desirous of again seeing you. You know what that means from me, and that it is no form, but the simple expression and result of the respect and attraction I feel for a mind that ventures to read direct in God's own book, and not merely thro' man's translation of that same vast and mighty work.
In a letter to Andrew Crosse, as quoted in Eugen Kölbing's Englische Studien, Volume 19 https://archive.org/stream/englischestudien19leipuoft#page/157/mode/1up (1894), Leipzig; O.R. Reisland, "Byron's Daughter", p. 157.
„Perhaps you have felt already, from the tone of my letter, that I am more than ever now the bride of science. Religion to me is science, and science is religion. In that deeply-felt truth lies the secret of my intense devotion to the reading of God's natural works. It is reading Him. His will — His intelligence; and this again is learning to obey and to follow (to the best of our power) that will! For he who reads, who interprets the Divinity with a true and simple heart, then obeys and submits in acts and feelings as by an impupulse and instinct. He can't help doing so. At least, it appears so to me.“

„I do not regret the sufferings and peculiaties of my physical constitution. They have taught me, and continue to teach me, that which I think nothing else could have developed. It is a force and control put upon me by Providence which I must obey. And the effects of this continual disciple of facts are mighty. They tame the in the best sense of that word, and they fan into existence a pure, bright, holy, unselfish flame within that sheds cheerfulness and light on many.“

Contesto: With all my wiry power and strength, I am prone at times to bodily sufferings, connected chiefly with the digestive organs, of no common degree or king. I do not regret the sufferings and peculiaties of my physical constitution. They have taught me, and continue to teach me, that which I think nothing else could have developed. It is a force and control put upon me by Providence which I must obey. And the effects of this continual disciple of facts are mighty.

— Ever yours truly. "A. A. Lovelace."
„[The Analytical Engine] might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine…Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.“
As quoted by Menabrea, Luigi (1842). Sketch of the Analytical Engine invented by Charles Babbage Esq.. Scientific Memoirs (Richard Taylor): 694.
„When I behold the scientific and so-called philosophers full of selfish feelings, and of a tenency to war against circumstances and Providence, I say to myself: They are not true priests, they are but half prophets — it not absolutely false ones. They have read the great page simply with the physical eye, and with none of the spirit within. The intellectual, the moral, the religious seem to me all naturally bound up and interlinked together in one great and harmonious whole… That God is one, and that all the works and the feelings He has called into existence are ONE; this is a truth (a biblical and scriptural truth too) not in my opinion developed to the apprehension of most people in its really deep and unfanthomable meaning. There is too much tendency to making separate and independent bundles of both the physical and the moral facts of the universe. Whereas, all and everything is naturally related and interconnected. A volume could I write you on this subject.“

„Our family are an alternate stratification of poetry and mathematics.“

„[...] engine is the material expression of any indefinite function of any degree of generality and complexity.“
As quoted by Rosen, Kenneth H. (2013). Discrete Mathematics and Its Applications, McGraw-Hill, ISBN 9780071315012. p.29.
„I may remark that the curious transformations many formulae can undergo, the unsuspected and to a beginner apparently impossible identity of forms exceedingly dissimilar at first sight, is I think one of the chief difficulties in the early part of mathematical studies. I am often reminded of certain sprites and fairies one reads of, who are at one's elbows in one shape now, and the next minute in a form most dissimilar.“
As quoted in Toole, Betty Alexandra (1998), Ada, the Enchantress of Numbers: Prophet of the Computer Age, Strawberry Press, ISBN 0912647183. p. 99
