[ARCHIVED CONTENT] Treatment of Alan Turing was "appalling" - PM | Number10.gov.uk - 0 views

  •  
    Alan Turing made both changes in technology and mathematics along with changes in societal norms.  In this article it talks a little of his influence on the gender issue.

  • We can, he thinks, know with certainty that God exists. We can also know about morality with the same precision we know about mathematics, because we are the creators of moral and political ideas
  • Locke gives us a theory of natural law and natural rights which he uses to distinguish between legitimate and illegitimate civil governments, and to argue for the legitimacy of revolt against tyrannical governments.

      and then this other paragraph begins the division
  • If one reflects somewhat upon the connection that discoveries have with one another, it is readily apparent that the sciences and the arts are mutually supporting, and that consequently there is a chain that binds them together. But, if it is often difficult to reduce each particular science or art to a small number of rules or general notions, it is no less difficult to encompass the infinitely varied branches of human knowledge in a truly unified system
  • We can divide all our knowledge into direct and reflective knowledge. We receive direct knowledge immediately, without any operation of our will; it is the knowledge which finds all the doors of our souls open, so to speak, and enters without resistance and without effort. The mind acquires reflective knowledge by making use of direct knowledge, unifying and combining it.

  • p here a moment and glance over the journey we have just made. We will note two limits within which almost all of the certain knowledge that is accorded to our natural intelligence is concentrated, so to speak. [34] One of those limits, our point of departure, is the idea of ourselves, which leads to that of the Omnipotent Being, and of our principal duties. The other is that part of mathematics whose object is the general properties of bodies, of extension and magnitude. Between these two boundaries is an immense gap where the Supreme Intelligence seems to have tried to tantalize the human curiosity, as much by the innumerable clouds it has spread there as by the rays of light that seem to break out at intervals to attract us. One can compare the universe to certain works of a sublime obscurity whose authors occasionally bend down within reach of their reader, seeking to persuade him that he understands nearly all. We are indeed fortunate if we do not lose the true route when we enter this labyrinth! Otherwise the flashes of light which should direct us along the way would often serve only to lead us further from it. The limited quantity of certain knowledge upon which we can rely, relegated (if one can express oneself this way) to the two extremities of space to which we refer, is far indeed from being sufficient to satisfy all our needs. The nature of man, the study of which is so necessary and so highly recommended by Socrates, is an impenetrable mystery for man himself when he is enlightened by reason alone; and the greatest geniuses, after considerable reflection upon this most important matter, too often succeed merely in knowing a little less about it than the rest of men. The same may be said of our existence, present and future, of the essence of the Being to whom we owe it, and of the kind of worship he requires of us. Thus, nothing is more necessary than a revealed Religion, which may instruct us concerning so many diverse objects. Designed to serve as a supplement to natural knowledge, it shows us part of what was hidden, but it restricts itself to the things which are absolutely necessary for us to know. The rest is closed for us and apparently will be forever. A few truths to be believed, a small number of precepts to be practiced: such are the essentials to which revealed Religion is reduced. Nevertheless, thanks to the enlightenment it has communicated to the world, the common people themselves are more solidly grounded and confident on a large number of questions of interest than the sects  [35] of the philosophers have been.

      The role of religion is to fill in the gaps that man cannot discover on his own. The difference for us is that someday we will know.
  • The advantage men
  • found in enlarging the sphere of their ideas, whether by their own efforts or by the aid of their fellows, made them think that it would be useful to reduce to an art the very manner of acquiring information and of reciprocally communicating their own ideas. This art was found and named Logic. It teaches how to arrange ideas in the most natural order, how to link them together in the most direct sequence, how to break up those which include too large a number of simple ideas, how to view ideas in all their facets, and finally how to present them to others in a form that makes them easy to grasp. This is what constitutes this science of reasoning, which is rightly considered the key to all our knowledge. However, it should not be thought that it [the formal discipline of Logic] belongs among the first in the order of discovery. The art of reasoning is a gift which Nature bestows of her own accord upon men of intelligence, and it can be said that the books which treat this subject are hardly useful except to those who can get along without them. People reasoned validly long before Logic, reduced to principles, taught how to recognize false reasonings, and sometimes even how to cloak them in a subtle and deceiving form. [38]

      The last couple sentences are interesting because they talk about the human perspective timeline, how we seem to think that simply because something was recently discovered doesn't mean it didn't exist before then. Atom for examplke have always existed but we only recently have begun to discover their true nature.
  • Too much communication can sometimes benumb the mind and prejudice the efforts of which it is capable. If one observes the prodigies of some of those born blind, or deaf and mute, one will see what the faculties of the mind can perform if they are lively and called into action by difficulties which must be overcome.
  • The science of communication of ideas is not confined to putting order in ideas themselves. In addition it should teach how to express each idea in the clearest way possible, and consequently how to perfect the signs that are designed to convey it; and indeed this is what men have gradually done.
    • Erin Hamson
       
      The importance of both sharing ideas, for the general benefit of man, and discovering things on our own, for our progression.
  • The general system of the sciences and the arts is a sort of labyrinth, a tortuous road which the intellect enters without quite knowing what direction to take. Impelled, first of all, by its needs and by those of the body to which it is united, the intelligence studies the first objects that present themselves to it. It delves as far as it can into the knowledge of these objects, soon meets difficulties that obstruct it, and whether through hope or even through despair of surmounting them, plunges on to a new route; now it retraces its footsteps, sometimes crosses the first barriers only to meet new ones; and passing rapidly from one object to another, it carries through a sequence of operations on each of them at different intervals, as if by jumps. The discontinuity of these operations is a necessary effect of the very generation of ideas. However philosophic this disorder may be on the part of the soul, [57] an encyclopedic tree which attempted to portray it would be disfigured, indeed utterly destroyed.
  • It is only after having considered their particular and palpable properties that we envisaged their general and common properties and created Metaphysics and Geometry by intellectual abstraction. Only after the long usage of the first signs have we perfected the art of these signs to the point of making a science of them. And it is only after a long sequence of operations on the objects of our ideas that, through reflection, we have at length given rules to these operations themselves.

The Engines - The Babbage Engine | Computer History Museum - 0 views

  • Difference engines are strictly calculators. They crunch numbers the only way they know how - by repeated addition according to the method of finite differences. They cannot be used for general arithmetical calculation. The Analytical Engine is much more than a calculator and marks the progression from the mechanized arithmetic of calculation to fully-fledged general-purpose computation.
  • Physical Legacy Aside from a few partially complete mechanical assemblies and test models of small working sections, none of Babbage's designs was physically realized in its entirety in his lifetime. The major assembly he did complete was one-seventh of Difference Engine No. 1, a demonstration piece consisting of about 2,000 parts assembled in 1832. This works impeccably to this day and is the first successful automatic calculating device to embody mathematical rule in mechanism. A small experimental piece of the Analytical Engine was under construction at the time of Babbage's death in 1871. Many of the small experimental assemblies survived, as does a comprehensive archive of his drawings and notebooks. The designs for Babbage's vast mechanical computing engines rank as one of the startling intellectual achievements of the 19th century. It is only in recent decades that his work has been studied in detail and that the extent of what he accomplished becomes increasingly evident.

George Boole (Stanford Encyclopedia of Philosophy) - 0 views

  • George Boole (1815–1864) was an English mathematician and a founder of the algebraic tradition in logic. He worked as a schoolmaster in England and from 1849 until his death as professor of mathematics at Queen's University, Cork, Ireland. He revolutionized logic by applying methods from the then-emerging field of symbolic algebra to logic. Where traditional (Aristotelian) logic relied on cataloging the valid syllogisms of various simple forms, Boole's method provided general algorithms in an algebraic language which applied to an infinite variety of arguments of arbitrary complexity.
  • Starting at the age of 16 it was necessary for Boole to find gainful employment, since his father was no longer capable of providing for the family. After 3 years working as a teacher in private schools, Boole decided, at the age of 19, to open his own small school in Lincoln. He would be a schoolmaster for the next 15 years, until 1849 when he became a professor at the newly opened Queen's University in Cork, Ireland. With heavy responsibilities for his parents and siblings, it is remarkable that he nonetheless found time during the years as a schoolmaster to continue his own education and to start a program of research, primarily on differential equations and the calculus of variations connected with the works of Laplace and Lagrange (which he studied in the original French).

Overview - The Babbage Engine | Computer History Museum - 0 views

  • Babbage embarked on an ambitious venture to design and build mechanical calculating engines to eliminate the risk of human error in the production of printed tables. The 'unerring certainty of machinery' would solve the problem of human fallibility. His work on the engines led him from mechanized arithmetic to the entirely new realm of automatic computation. Tabular errors provided a practical stimulus. But this was not his only motive. He also saw his engines as a new technology of mathematics.
  • It was not only the grindingly tedious labor of verifying a sea of figures that exasperated Babbage, but their daunting unreliability. Engineering, astronomy, construction, finance, banking and insurance depended on printed tables for calculation. Ships navigating by the stars relied on printed tables to find their position at sea. The stakes were high. Capital and life were thought to be at risk.

G. Stanley Hall - Wikipedia, the free encyclopedia - 0 views

  • There, Hall objected vehemently to the emphasis on teaching traditional subjects, e.g., Latin, mathematics, science and history, in high school, arguing instead that high school should focus more on the education of adolescents than on preparing students for college.
  • Hall believed that humans are by nature non-reasoning and instinct driven, requiring a charismatic leader to manipulate their herd instincts for the well-being of society. He predicted that the American emphasis on individual human right and dignity would lead to a fall that he analogized to the sinking of Atlantis.
  • Hall coined the phrase "storm and stress" with reference to adolescence, taken from the German Sturm und Drang movement. Its three key aspects are conflict with parents, mood disruptions, and risky behavior.
