  • History of Lines–Straightening out the Thames

    JF Ptak Science Books   Quick Post

    The architect Willey Reveley straightened out curves and curved out straight lines.

    As we can see here he had the idea of constructing a straightaway through the three famous bends of the River Thames in East London.  The straight part would be used for commerce while the bends would become docks and yards.  

    Another vision by Reveley is seen below, from page 113 of Alexander Forrow’s The Thames and its Docks, a Lecture (London), 1877 (the full text available at the Internet Archive):

    With all of this straightening-out of the river thinking going on in Reveley it is interesting to see that when he applied his brain to the the world of very straight lines as they exist in prisons that he went the other way–following the idea and commission by Jeremy Bentham, Reveley created plans for a circular prison. Bentham’s Panopticon was an idea that wouldn’t leave Bentham and occupied at least one small part of his brain throughout the 1790’s–I’m not sure where in Reveley’s head the idea lived, but it didn’t live there for long, as the architect died at a very young 39 in 1799. Bentham (born in 1748) lived until 1832, and never did see his Panopticon constructed. (Then again, he may come to see it if someone showed it to him, as his head has been preserved as an on- and off-again display at University College…)

  • Claude Shannon as the Father of (1) Info Theory or (2) Information Age or (3) Both?

    JF Ptak Science Books  Quick Post

    George Boehm wrote a fine, semi-offhanded paper on Claude Shannon’s inventiveness: “Gypsy, Model VI, Claude Shannon, Nimwit, and the Mouse”, in Computers and Automation, volume 2, number 2, March 1953.  (The article is found on pp 1-4 in the issue of 37pp.) 

    Shannon (1916-2001) is widely seen as being the “father of information theory” though it might be more accurate to refer to him as the “father of the information age”–either title will do just fine.

    Shannon basically established the foundation of the digital circuits in his 1937 A Symbolic Analysis of Relay and Switching Circuits, which was also one of those great dreams-come-true parts of graduate school, when your masters’ thesis is actually something that means something, and with Shannon’s paper that “something” was exponential. It is the stuff of dreams but Shannon actually did it and did so with this paper at the age of 21. In the midst of a brilliant young career he also produced (in 1948, 11 years later) another great landmark effort,  A Mathematical Theory of Communication, which is the pioneering paper on information theory and which was so brilliantly composed that its framework is still in place after 67 years. A year later came Communication Theory of Secrecy Systems, a work which established cryptography as a science more than a system. And on and on. 

    I like that Shannon was born in Petosky, Michigan, up there on the choppy Little Traverse, and all of those big-pebble Petosky fossil/stones.

    This is a very insider-y semi-offhand but solid review of some of the gadgetry and robotic work of Claude Shannon:

  • Panorama–Boxing Day, 1920

    I saved this image for the real Boxing Day, and then of course promptly forgot it–I’ve missed the day, though perhaps it really doesn’t matter, because even though it isn’t ‘boxing”, it is “boxing”.

    The boxing in question in this fantastic image is the Jack Dempsey-Billy Miske Heavyweight Championship Fight on 6 September 1920. Jack Dempsey retained his heavyweight crown by knocking out Billy Miske in the third round of this scheduled 10-round fight (the first to be broadcast by radio) before the crowd of 11,700–the impressiveness of the meeting hammered home with this 3600 panorama.

  • Chess-Playing Computers and “Mechanized Thinking”, 1950

     JF Ptak Science Books   Quick Post

    ShannonI was reading the great Claude Shannon’s article, “A Chess-Playing Machine”, in the Scientific American issue for February 1950 (volume 182, No. 2, pp 48-52). It is the first popular appearance of Shannon’s technical paper (which would appear a month later in the Philosophical Magazine), and is one of the earliest appearances of an attempt to understand the necessities of a computer for playing a game of chess.

    David Shenk in his wonderful The Import Game: a History of Chess sums up the background to the Shannon very nicely: 

    “Since the mid-1940s, scientists had aimed to create a thinking machine, an apparatus that could compete with or even surpass the human brain in logical operations, pattern recognition, problem solving and even language. Chess was found to be a useful testing ground because of its combination of simple rules and mind-bending complexity… Shannon was fascinated by chess’ potential in the pursuit of what he called ‘mechanized thinking.’ But he became convinced that computer chess and other AI pursuits should not be modeled on human thought… Computers, at least as they were understood then, could calculate very quickly, following programmed instructions. This particular strength—and limitation—of computers suggested a different route for AI, a new sort of quasi-intelligence based on mathematical computation. Chess would be a central proving ground for this new type of intelligence. Theoretically, at least, the game could be fully converted into one long mathematical formula” –Shenk, pp 201, 211

    “The father of the modern chess computer was MIT’s Claude Shannon, a mathematician regarded as the founder of information theory, who in 1950 published a paper called ‘Programming a Computer for Playing Chess. Shannon identified some of the algorithms and techniques that form the backbone of chess programs today.”–Nate Silver, The Signal and the Noise

     

  • A Beautiful and Famous Comet, 1874

    JF Ptak Science Books  Quick Post

    Comet 1874862

    This lovely image of the head and envelopes of Coggia’s Comet (C/1874 HI) as seen by Norman Lockyer on a summery night “under first-rate atmospheric conditions”, July 12, 1874, and then drawn by him–and then published almost immediately in Nature on July 16, 1874, the magazine that Lockyer edited.  This image is beautiful and significant for its “striking differences” from earlier cometary images

    “Without doubt, C/1874 H1 (Coggia) was a beauty; a true great comet. At its brightest, it probably exceeded the first magnitude and displayed a series of envelopes within its coma that astronomers compared with Donati’s Comet 16 years earlier. Suitably placed observers also noted maximum naked-eye tail lengths reaching 70 degrees as the comet passed near Earth in July.” Seargent, David A. J. (2008). “C/1874 H1 (Coggia)”. The greatest comets in history. p. 126. –Wiki, http://en.wikipedia.org/wiki/C/1874_H1#cite_ref-6

  • List of African-American Newspapers, 1895

    JF Ptak Science Books   Quick Post

    African-american

    I found this list (below) of 19th-century African-American newspapers in James T. Haley’s Afro-American Encyclopaedia (Or, the Thoughts, Doings, and Sayings of the Race, Embracing Lectures, Biographical Sketches, Sermons, Poems, Names of Universities, Colleges, Seminaries, Newspapers, Books, and a History of the Denominations, Giving the Numerical Strength of Each. In Fact, it Teaches Every Subject of Interest to the Colored People, as Discussed by More Than One Hundred of Their Wisest and Best Men and Women), which was published in 1895 in Nashville (639pp,by Haley & Florida). The book  was digitized by the University of North Carolina at Chapel Hill as part of their digitization project,   Documenting the American South. It is a fantastic thing absolutely filled with information and insight.  

    • Full text found here: http://docsouth.unc.edu/church/haley/haley.html

    The newspaper section starts with this introduction about the need for newspapers followed by a statement on the involvement, intelligence, and capacity to publish a newspaper:

    Shall I Take a Paper?

    “AT this season of the year, when publishers are making special offers to the reading public, we are all debating the mental fare with which we shall spread our table in 1895. We ought to have first a good church paper thoroughly representative of our denomination.”

    “The Methodist ought to have the South- Western Advocate, published at New Orleans; the African Methodist ought to have the Christian Recorder, published at Philadelphia; the Congregationalist ought to have The Congregationalist, published at Boston, or the The Advance, published at Chicago, and so on for the Baptists, Episcopalians,”

    “Evangelists and other denominations among us. Each home ought to have its church paper. Next to that stands some good clean helpful race journal. Get one, in the columns of which the editors are seeking to help the race up, and not working to pull it down. When you subscribe for a race journal get one in which the editors display not pessimistic, but optimistic views of the race.”

    “It will be well to remember that it takes brains to edit a newspaper, and men who have not been trained to think are hardly men to be entrusted with the perilous task of giving direction to public opinion. The editorial chair requires more than that culture gotten from the reading of newspapers. The editor who is sending out week by week his paper into the world ought to be able to grapple with the problems of the day and think them through. There is too much guessing on the grave social problems of the day by editors. Riots and mobs are the result of false teaching, both on the part of the hotheaded anarchists and incompetent editors who are not anachists. In selecting your race journal for the next year find one whose editorial columns show moderation, and one which is not always squared off with a chip on its shoulder daring someone to knock it off. The paper which busies itself with fighting its contemporaries cannot be of very much help to you. When you raise the question about taking a race journal remember there are two reasons especially to be remembered why you should. The first is a duty you owe to yourself to keep up with the movements among your own people. Second, you owe it to the race to support laudable enterprises which look to the betterment of the race. Let us remember, too, that the press, the pulpit and the platform have been the great liberators of the nations In this land of ours we need the influence of all of these to plead our cause up and down the length of our land. Put some good race weekly on your list for 1895.”–Cleveland (Ohio) Gazette.

  • Human Advertising Bots: Berlin, 1919

    JF Ptak Science Books   Quick Post

    These two photographs of the streets of Berlin come from the 19 May 1919 issue of Illustrirte Zeitung. Evidently there are lots of people carrying placards and advertisement vehicles, and–as we see in the lead photo–some people wearing costumes of the advertised product. Between the two images, it seems that a good percentage of the crowds are actually advertising media.  

    Gereman ads 1919864

    I don’t know  why this is the case.  Germany certainly was in a bad place seven months after the end of WWI, (recovering from food shortages, experiencing money shortages, numerous political parties fighting among themselves and everyone fighting with Communists),  and just three months before the adoption of the Weimar constitution, and two months after what would be the disastrous Versailles Treaty was signed. Maybe there was a shortage of newsprint, or a shortage of money for people to buy magazines and/or newspapers, which mean people weren’t seeing advertisements and which means that perhaps retailers were being hurt even further, and so an army of placard-holders was let loose on the streets of Berlin and other cities to get out the consumption-reminders..  Or maybe not. In any event, the photographs are stunning.

  • I’ve Never Done This Before, and I’ll Never Do It Again (1918)

    JF Ptak Science Books  Quick Post

    Here we are at the beginning of a new baseball season, everyone daisy-fresh and dazzlingly shiny, so I thought I’d share this fine image from my collection of World War I news service photographs.  In 1918 all was for fun and  charity of the British Blue Cross, and Ms. Phyllis Broughton joined the festivities, though whether see is entirely reluctant or determined, we’ll never know.  Perhaps both–whatever the case, she did what she was asked to do for a good cause, with a stiff upper lip. 

    (The typed description on the coarse paper was intended for the newspaper ro journal that published the photograph to use for the caption.)

  • The Outsider’s Outsider PoliSci Insider (1910)

    JF Ptak Science Books   Post 2429     Outsider Logic series

    Outsider  classic drama859 detail

    There is a new find in my collection of Outsider Texts: The Classic Drama of International Studies with Unity of Shakespeare in Five Acts, written anonymously by the Keystone International University in 1910.  

    It is impenetrable. Well, it is impenetrable as a whole going from page to page, and maybe from sentence to sentence, but within sentences is where there is some sense and the series’ most penetrable aspects; but at the end of a “chapter” somehow the words you’ve read have all gone away into some brittle aphasic two-dimensional soup.

    The work is complete in three pamphlets covering five parts which constitute two parts (but not three) of the fifth and sixth book “of the later K.I.U. Publications”, all of this happens before we open the covers of these little five-inch-tall publications–they are packed and are already confusing, and it only gets more so from there.  Every chance interaction with the text is baffling, though it does seem to be about the Teddy Roosevelt administration/Babylon, I think, a satirical Old Testament-laden prophetic-something–in rhyme.  

    My guess is that the anonymous author of this three-part series (paginated from page 122-192) may have been the university itself (?) in spite of the proclamation of it being in London, Washington, and Paris. I can find in a not-deep investigation no evidence of the university, nor can I find any copies of these pamphlets on the web, nor is there any trace of them whatsoever in WorldCat. 

    I just like these personal logical systems–or at least I like the idea of them, even though many are just impossible to read.  There is a surprise, though, in one:  a political “cartoon” of suits, a very odd representation of Theodore Roosevelt and I-don’t-know-what-else.  

    Outsider  classic drama859

    The illustration makes everything worthwhile…or maybe it doesn’t. There is a high creep factor to it, though it was carefully prepared as a woodblock or cut of some sort.  

    I wasn’t going to spend this much time on this adventure in words and just publish the artwork, but I got sucked in a little to see if there was anything there, but the entrance is also the exit, and as soon as you’re in you’re out.  As my brother-in-law would say: “It is what it is” though maybe it wasn’t what it was.

  • Dots of Death, 1937

    JF Ptak Science Books  Quick Post    

    This intriguing and striking collection of dots is actually an articulated portrait of death. Road death.  The composite picture appeared in the Illustrated London News on December 18, 1937, and when the reader opened the magazine to the big two-page spread–11×18″ big–they were probably shocked. The picture represents 67,000 people killed on British roads in auto accidents over ten years.  “Nothing less than appalling” is what the heading reads. 

    Just down the road, at the end of WWII eight years later, you would need 1,200 of these double sheets to represent the dead of that conflict.
