  • Colossus in the Colosseum

    JF Ptak Science Books   Quick Post

    Wimshurst machine205

    Here’s an interesting combination of sweat and electricity–an enormous electrical device that was on display in an exhibit of “natural magic” at the Colosseum in Regent’s Park in 1839.  The large disk that the two guys are turning is actually larger in real life, being 7′ in diameter, the conductor being varnished copper, and the conducting balls being gilded–it must have been a very shiny experience, especially when they generated their electric spark.  In 1839 this was the largest electrical generating device in the world.  (I have a tiny version of that device here, something made out of old records coated with copper and found ball glasses acting as Leyden jars, all painted and varnished, the work of an 8 year old in 1925 who went on to a career in astronomy and became the most celebrated eclipse follower in the mid 20th century.)

    This monster is made just 39 years after Volta’s first battery was made,  and not long after Oersted generated the first magnetic field from an electric current in 1820, the same year as Ampere’s solenoid. There were many quick and brilliant development from then to 1839 (also the year in which Daguerre perfected his collaborative work with Niepce to produce the photographic camera), not the least of which was the  Davidson’s creation of the first electric motor car/land locomotive, again in that same full year of 1839:

  • Life in Stone–Some Interesting Work by the Great Fr. Kircher (1678)

    JF Ptak Science Books   Post 2825

    The great semi-mystifying polymath Athanasius Kircher (1602-1680) lived for a long time and filled his life with ideas and words,  producing dozens of books during his time on Earth, some of which were never published even though written, some manuscripts lost forever. His was a massive output of extraordinary breadth.  He wasted little time what I can see, writing on a spectacular range of subjects, enlightening people, confusing people, generating great theories and some bad ideas. 

    The images below comes from his Mundus Subterraenus (“Athanasii Kircheri Mundus subterraneus in XII libros digestus… “), an edition published in 1678, and which was concerned mainly with geology and the theory of the Earth.  Kircher a product of the great Jesuit institution, the Collegio Romano, postulated the structure of the interior of the Earth, the origin of heat, the source of the tides, the composition of light, mechanics, the structure of music, linguistics, astronomy, and of course the existence of the Virgin Mary in amber.  There was also a fair amount of work on one of his side interests that populated a number of his works, alchemy and the search for the organization of materials.

    But what I am looking at today with Kircher is the Mary-in-Amber part, his investigations (and theorizing, and documentation) on naturally-appearing, organic objects found in inorganic material–rocks and minerals–like these birds:

    Kircher  lapidibus birds451

    Which is a detail from  

    Kircher  lapidibus birds449

    The engraving, entitled Figure Volucrum, quas Natura in lapidibus depinxit, ex variis Museia decerpt et aliunde transmissa (or “Figures of winged creatures, painted by nature on stones, taken from various museums, and otherwise transmitted.”) shows Kircher’s collection of anthropomorphically based inorganic items.  It is a remarkable exercise to try and place yourself within the context of the scientific world of Kircher’s time, 350 years ago, and try to explain these naturally-occurring phenomena, without even the benefits of the conception of long geologic time, or of expanded time in general.  

    The descriptive text (at the bottom of the engraving) from Kircher on these objects is translated, as follows:

    1.  The first figure represents a head of a Stork, together with some, but I do not know what, quadruped. At the top is something like a human face. Extracted from Aldobrandinot (see PI. XXIII. Fig. 1). 
    2.  Shows various forms and parts of animals, winged creatures as well as quadrupeds, although very imperfect, the cause of which we give in the physical examinations (see PI. XXIII. Fig. 2). 
    3.  Represents the figures of two birds expressed by nature on marble in the church of St. George’s, at Venice, referred to by Ambrosinua (see Vol. VII. PI. II. Figs. 3, 4). 
    4.  Shows the head of an Owl, surrounded by rudiments of other birds (see PI. XXIV. Fig. 2). 
    5.  Represents the figure of a Wagtail, or as others prefer, of a Peacock (PI. XXIV. Fig. 3). 
    6.  Shows the figure of a monstrous bird (Vol. VII. PI. II. Fig. 4). 
    7.  The figure of a Merle (Vol. VII. PI. II. Fig. 5).

  • Finding Anthropomorphism in an Electric Chair Patent (1897)

    JF Ptak Science Books  Quick Post

    This image of among the first electric/electrocution chairs is based on the designs of Dr. Alfred P. Southwick (1826-1898, MDS, DDS, SUNY Buffalo), who came up with the idea and started experimenting with it beginning in 1881. His was a mission of mercy, looking to find a quick if not instant salient to carry out the death penalty of a convicted murderer. NY Governor David B. Hill (1843-1910) looked to Southwick for a solution to a more humane way of executing people, establishing a distinguished panel of advisers to help him with this task. (In the small-world department, Hill succeeded Grover Cleveland as governor in 1885 following Cleveland’s election as president of the U.S.–he also acted as executioner in at least two cases while he was the Sheriff of Erie county in the mid 1870s.)

    Southwick’s design/chair was first used on the condemned criminal William Kemmler in August 1890. Most everyone who witnessed this first attempt were aghast at the spectacle; George Westinghouse is reported to have uttered that the executions “would have been better off using an axe”. Theoretically the first application of electricity kills the brain in less time than it takes the body to respond to pain. This seems not to have been the case in many instances.

    No tong afterwards Edwin F. Davis (1846-1923) conducted his own research on an effective and humane way to execute people and was awarded a patent in August 1897 for his “electrocution chair”. Davis would serve as NY state’s “electrician”/electrocutionist from 1890-1914, delivering the final blow to 240 of the condemned during that time.

    It was strange to me how anthropomorphic the design was, including the obvious head and less so for arms and feet. Overall, I think the relationship to a human form is unmistakable. 

    Electric chair patent

    Excerpt from the article illustrating the 1888 electric chair:

    “Execution by Electricity. The State of New York may pride herself in the fact that the gallows is to be banished and a more humane and scientific method of executing criminals is to be instituted. On June 4 Governor [David B.] Hill signed the bill authorizing that criminals should be put to death by an electric shock. The bill is to go into effect on January 1 1889 and new method of execution be applied in the punishment of crimes committed after date.”

    SciAm writes that “instant death” occurs with the electric chair—it doesn’t. The condemned would be lucky to have their brains damaged enough to not register pain, as it takes 45 seconds to several minutes for death to occur.

    “…the criminal is seated bound to a chair having a metal seat connected with one pole of the current. At the back of the chair there is an adjustable head rest having a metal plate on its face and a metal band which passes around the forehead of criminal. The wires may be connected with dynamo which according to the bill may be of any approved type or the current may be supplied from electric light plant or there may be a private plant arranged especially for that purpose at the place of execution. Sponges or dampened cloths should be at the points of contact with the convict to render connection more perfect. At the proper moment switch is turned by the officer and instant death ensues. The current passes along the spinal column and the brain and nerve centers. The current may be few moments to bring about complete exhaustion.”

  • Tech Quiz: an Elevation of an Elevation (1880)

    JF Ptak Science Books   Quick Post

    This is just a lovely little mechanical drawing that I found in the pages of the 5 May 1880 issue of the Comptes Rendus de l’Academie des Sciences and I decided to share it. The Comptes Rendus is a very old workaday maintstay in my job, and I have become very familiar with it over the years, and in its great heyday in the 19th c it published all manner of scientific events over many disciplines, and at the highest level for each field. I’ve never really paid too much attention though to the illustrations in the journal as general “art” as I have done with other journals (like the Annalen der Physik)…why, I don’t know. In any event I was working on a two-part Pasteur paper in this volume and noticed this elevation of a “siphon” for Napoleon’s canal Saint-Martin, which is just about at the center of old Paris. 

    SciArt CR 1880 Siphon

    The structure does look a little like a headphone, and as pretty as this is, it subject matter wasn’t. This is a sewer line that would allow the sewage and etc. to flow over the canal along the arch of a bridge…which makes this an interesting problem. I mean, it is a necessary and important thing, dealing with waste, and that is exactly what this pipe was all about. 


  • The Department of “What is It?” (#6) Careless Chaos Catcher.

    Okay, so I’ve given it mostly away in the title–if not for that, this wouldn’t be a very obvious contraption, would it?  

    People catcher detail

    There must have been a lot of people who had a problem with street cars in the 19th and early 20th centuries because in my meanderings through the Scientific American I have seen quite a few suggestions for dealing with the pedestrian vs the heavy moving metal problem. Many of them have to do with the humanified locomotive cow-catcher–that is an apparatus that would somewhat safely scoop up the unfortunate pedestrian before they became very fatally unfortunate.  Here’s just one example, found in the February 3, 1894 issue:

     

    Pepople catcher380

    Neither the scoopee nor the scooper look pleased.  

    This problem is better illustrated by an early film of street traffic–it is amazing in a way that the orchestration of non-fatalities is so seemingly superb, the coercive element of the destruction of liminal space pretty well hidden in the seeming confusion.

    So, this is clearly film of some sort, and seems to be a picture of something, but a picture of what? This is a positive of a negative, and the major hint here is that the year it was made was 1923.

  • Department of “What is It?” #4 (1887)

    Here’s another in this developing and fun series in the What-is-It? category. At first it reminded me of Renaissance woodcuts of various stages of creation anointed by a coy hand of the creator. This one though is late 19th century and has a definite highly au courant “Oriental” theme which so far as I can tell has nothing to do with the telling of the story of this object.  It looks a little like a multi-horned phonograph (already in existence by about a decade at this point), and it also looks a little like a Chinese earthquake detector. It is surprising for what it actually represents, and it is a lot larger than you’d think, with the figure in the background definitely not to scale. Plus, it comes into the world a few years earlier than its gigantically famous counterpart, as though it had gone back in time…

    [I apologize for the fuzziness at the top of the image here but I couldn’t get the volume of Nature flat enough on the scanner to avoid the degradation.]

    What is it thermometer

    In the wonderland world of early applications of electricity to anything comes this marvelous image of an electrical thermometer from Nature for March 17, 1881.The original image is only about 3″ tall, and I could not resist reproducing it in what is almost a 3:1 ratio. As pretty as it was/is, the implementation was a bit of a picture of a soggy sandwich.

    Evidently the platinum screws running up the side of the thermometer (at every 3 degrees, though it could be refined to <1-degree increments), were connected to an alerting operator like a bell or some such thing.  That way, if something was being heated to a certain temperature and the temp changed, an alarm would sound, and the whole process could be viewed remotely.  Why this would be necessary I am not so sure–even the author admitted that the whole thing would be very cumbersome with the large number of insulated wires being tracked into the observing station.  In any event, the image is striking, if not the idea.
