From Duke University’s Emergence of Advertising in America archive comes this beautiful advertisement for Diamond Dyes, published sometime between 1853 and 1920. The ad uses the negative afterimage optical illusion, which is a common sight in most first year psychology textbooks, although usually in a much more boring way. This image is actually kind of frightening.

From Bre Pettis via Make Magazine come these wonderful diagrams illustrating the dangers of electrocution in typically glorious Weimar fashion. From the book Elektroschutz in 132 Bildern By Stefan Jellinek. I like to think of these as filling a need to acculturate people to the dangers of electricity, and based on these images, I would guess electricity was pretty dangerous technology at the time.

This is one of the most normal diagrams in the collection.

One of the stranger ones.

Neuroscience + Woodwork = Awesomeness

In this short post I look at some illustrations produced by the Weimar era popular science writer and illustrator Fritz Kahn. Theses illustrations are interesting because they break with Kahn’s more popular man-as-machine metaphor (which I have explored in The Body Machines of Fritz Kahn) by depicting the body as a fantastic landscape. Produced early in Kahn’s career to me these illustrations present a more traditional and romantic view of the body than Kahn’s later work.

This first image is illustrates the glands of the skin as chimneys on the hand:

Chimneys of the Skin

The next image depicts the inside of blood vessels and could be considered a bit of a stretch as a body-landscape. However, I have seen exactly the same illustration in another Kahn publication with the sole addition of small fairy-people riding on-top of the blood cells through the vein. Unfortunately I seem to have lost the image at some point in my move from Toronto.

The Vein as a Tunnel

A bit more of a stretch is this illustration labeled “how the dessert cleans the tongue” where the tongue is a landscape being worked on by little figures who represent various foods and drinks. The reason this is a stretch is that the meme of little people working (and carrying out tasks) inside the body is very common in Kahn’s illustrations, including his body-machine images.  This image is part of a series of fascinating illustrations dealing with eating habits and I will definitely do a full post on in this topic in the future.

How the Dessert Cleans the Tongue

Next is an illustration meant to show the spead of the neural impulse compared to the speed of contemporary air travel and wireless communication. Interesting here is the choice of North and South America as the comparitive landscape, probably related to Kahn’s move to the United States following being smuggled out of Nazi Germany just before the outbreak of World War Two.

The Speed of the Neural Impluse

This last illustration is my favorite of the series and the image that prompted this quick post. This illustration is of a landscape drawn from the perspective of a person inside the nose looking out.

Google announced this week that they are partnering with Life Magazine to digitize the entire back catalog of Life’s images and are making them available through Google’s Image search platform. While looking through the archive I found a number of eclectic images from the history of psychology and decided to post some of the more interesting ones here. To be clear, I am not trying to tell a coherent history with this post; rather, I just selected the most iconic images I found that still illustrated some of the prominent trends in psychological research throughout the 20th century.

This first image depicts the Yale’s child psychology lab of Dr. Arnold Gesell in 1947 and is possibly my favorite for its surreal, B-movie, science fiction quality:

Child Psychology lab at Yale

According to Wikipedia:

Gesell made use of the latest technology in his research. He used the newest in video and photography advancements. He also made use of one-way mirrors when observing children, even inventing the Gesell dome, a one-way mirror shaped as a dome, under which children could be observed without being disturbed.

Here is a “The March of Time” video hosted on Google Video of a Gisell Dome in action.

Children have played an important role in the history of psychology and have an equally if not disproportionate place in Life’s images of psychology. In this picture a child navigates a glass obstacle in a box at Columbia University in 1940:

Child Navigating Glass Obstacles

Continuing the baby theme, this image from 1947 is described as showing “Baby John Gray Jr. happily playing in his Skinner box… [a] new-style crib which eliminates germs, drafts & constricting clothing because of temperature controls & slid-down glass.” Looks like a happy little tike to me:

Update: According to Dr. Christopher Green (of the wonderful and informative blog Advances in the History of Psychology) the “baby box” was not really a “Skinner box” (I had wondered about this) as it was not set up for conditioning. Instead, Skinner called it an “air crib” and it was also jokingly called a “Heir conditioner.”

Boxes for Babies

This image, from 1940, is of “a baby climbing pedestals which he has pushed together to reach the lollipop hanging from the ceiling at Normal Child Development Study at Columbia University.” I would like to see someone try to get this one past an ethics review board now:

A Baby Climbing Pedestals

This image is of Army recruits in Miami Beach, Florida taking aptitude tests in a movie theater in 1942. This is important because of the role of aptitude testing, especially in military and educational settings, to the growth of psychology in the United States in the early 20th century.

Army Recruits

Switching gears slightly as psychological research becomes more biologically oriented, this image from 1953 depicts a young girl whose “brain impulses are measured by an electroencephalograph, readings from electrodes cemented to the head may reveal tumor as cause of headache at the Headache Clinic, Montefiore Hospital.”

Girl with Electrodes

Here is an imaging technique I was not aware of from 1966, a “somersaulting x-ray machine being used to photograph the brain’s ventricles.” Looks kind of dangerous to me:

Somersaulting x-ray Machine

This image of a “patient resting on scales, showing a slight loss of skin moisture” is interesting and I would like to know more about what this research was trying to accomplish. Reminds me of a ancient (and possibly mythical) research technique I’ve heard about that balanced a subject like a teeter totter so carefully that blood flow changes during cognition would cause him to unbalance, kind of like an analogue fMRI.

Patient Resting On Scales

Kind of fancifully, this image labeled “studying mental disorders through laboratory research” from 1949 is a sign of things to come as well as a wonderful example of an almost purposely obtuse piece of scientific apparatus.

Studying mental disorders through laboratory research

Animal research has played a huge role in psychology, but more importantly, this image of a “cat pulling rat’s cart around floor as a relaxation from psychology experiments” is why the internets were invented:

Cat pulling rat's cart around floor

Note:

These images are copyrighted by Life Magazine (well.. so they claim, some of the images in the archive are definitely old enough to be in the public domain). I am assuming, however, that someone warned them that goggle-wearing, hot-air ballon flying bloggers are likely to both post and link to these images once they are in the wild, and that they are OKAY with this, at least for non-profit purposes. Clicking on any of the above images will bring you to Google Image’s page for the specific image.

Here is another illustration from Fritz Kahn’s encyclopediatic series of books “Das Leben des Menschen; eine volkstümliche Anatomie, Biologie, Physiologie und Entwick-lungs-geschichte des Menschen” (The Life of Humans: A Popular Anatomy, Biology, Physiology and a History of the Development of Humans) titled “In 70 Years the Man Eats 1,400 Times its Weight” which purports to show the amount of food the average man eats in 70 years as train cars full of food.

In 70 Years the Man Eats 1,400 Times its Weight

I was reminded of this particular illustration by an image I recently saw on Ptak Science Books (a blog that I can really only describe as a repository of wonderfully eclectic science and technology illustrations) which attempted to show 12,000 employees leaving a tire factor. Ptak uses it to illustrate the number of casualties of the Battle of the Somme (The Department of What Things Look Like: the Casualties of the Somme, Visualized) a task which is as monumental as it is heatbreaking. Here is a small version of the image for the purpose of comparison, but please go see his blog for a full sized image as well as many other wonderful things:

Here is another image from Ptak (A 117×1 Mile Blanket of Planes: What 185,000 Planes Looks Like) which uses a similar visual style to, this time from the London Illustrated News and showing the number of aircraft the United States planned to produce between 1942-194.

Which reminds me of one last illustration in which Kahn uses industrial metaphores to show incomprehensible numbers. Named “The Amazing Pump Within Our Bodies” this illustration uses a tanker trunks and a skyscraper to illustrate the amount of blood the heart pumps during one’s lifetime:

The Amazing Pump Within our Bodies

Unfortunately I’ve lost the source for this image.

• The Cycles of Virtue and Substance: Fritz Kahn and the Chemical Cycles of Man and Machine

In my previous post on the early 20th century science writer and illustrator Fritz Kahn (The Body Machines of Fritz Kahn) I explored how Kahn’s human-machine analogies broke down the barriers between humans and machines. In this post I want to look at some striking illustrations produced by Kahn of chemical cycles and how these images further located industrial machines as part of a single unitary nature.

The Cycle of Carbon Dioxide

This first image “The Cycle of Carbon Dioxide” is a fairly standard illustration showing the carbon-oxygen cycle in its relationship to man and plants. The illustration shows an early example of some of Kahn’s iconic methods, including using lines to depict the rays of the sun shining down and a rather stylized Germanic figure as his representation of man. The illustrations uses color to depict the functional path of the chemicals (an expensive technique at the time) with oxygen shown in blue and both carbon and carbon-dioxide shown in red. The tree has fruit only on the right hand — or carbon — side of the illustration, which is then connected with the man’s stomach, presumably both in terms of input and output.The symbols and colors were apparently a recent innovation of academic chemistry, although I have lost the citation that confirms this fact.

The Circulation of Water

The next image shows the “circulation of water” and is another fairly conventional image in that it does not transgress any traditional human-machine boundaries. On the left is a familiar water cycle — shown in blue — with ’steam’ shown rising from the ’sea’ and raining down on the earth where it runs back into the sea. On the right there are plants and an animal along with a man drinking from a cup.

I am not entirely sure what the barrel beside the man is suppose to represent. Presumably it contains the water, beer or wine that the man is drinking, although there appears to be a dark liquid pouring from the barrel onto the ground and although I doubt it is human or animal waste I have to admit that this was my first thought on seeing the image.

Now things get more interesting as Kahn starts placing machines and heavy industry into his illustrations. The next image is dramatically titled “The Cycle of Virtue and Substance” and prominently places both machines (in the form of a steam engine on the right hand side) and heavily industry (in the from of smokestacks in the background)  with the carbon-oxygen cycles which Kahn has already explored in a more conventional form.

The Cycle of Virtue and Substance

This is definitely my favorite image of the batch. The engine on the right is compared to the man on the left, with a fruit-bearing tree in the center connecting the two. In the background there are massed silhouettes of both human figures and huge industrial buildings and smokestacks. The comparison between the man and the engine is explicit: both consume the carbon and oxygen produced by the tree and both produce carbon dioxide which is then taken up by the tree, as well as fertilizer in the form of the human’s droppings (Kot) and the engine’s ash (Asche).

The title itself, “Der Kreislauf von Kraft und Stoff” (the cycles of virtue and substance) suggests more than just a objective illustration of how machines exchange chemicals in ways analogous to humans and plants or a pedagological method. The suggestion, I think, is the nourishing effects of industrial production on nature.

This image reminds me of another image that I used in my earlier post on Kahn called “Man and Machine” which also placed man and machine on equal functional grounds.

Man and Machine

This last illustration, “The Building of Carbohydrates by Plants” also gives prominent placement to industry in a chemical cycle. Although this illustration is mostly concerned with the formation of different types of plant material, Kahn again includes factories and smokestacks in the background.

The Building of Carbohydrates by Plants

These images (with the exception of “Man and Machine” which is from “Man in Structure and Function”) are from Kahn’s encyclopedian publication “The Life of Humans: A Popular Anatomy, Biology, Physiology and a History of the Development of Humans” (Das Leben des Menschen; eine volkstümliche Anatomie, Biologie, Physiologie und Entwick-lungs-geschichte des Menschen) which was published in Stuttgart 1929 by Kosmos Gesellschaft der Naturfreunde, a “Society of Friends of Nature” which published popular science books and periodicals and is apparently still active in some form today. This massive 5 volume set included more than 1600 pages, 1000 illustrations and almost 50 color prints and sets the iconography for many of Kahn’s later illustrations.

A final note: Those looking closely may notice that some of these images are signed by artists other than Fritz Kahn. At the time it was common for many different artists to work under one main illustrator who produces the entire work. In Kahn’s early work many illustrations bare the marks and signatures while in his later works he placed a “FK” trademark over the original artists signature.

This post is a continuation of my earlier posts (here and here) on using Google Insights to look into Google’s data on searches for Canadian political parties and leaders during this election season. Although I have many qualms about the use of this data and how generalizable it is, I am so far impressed with how well it syncs with the general zeitgeist about the ebb and flow of party popularity (although I havn’t figured out how to quantify that relationship yet — possibly by indexing the data from Google with polling data?). Obviously the population of Canadians using the internet — specifically Google — to search for political parties and leaders is not exactly the same as the voting population, and searches are not in themselves an indication of which party’s candidate someone is going to vote for. I do think it is interesting, however, how the search data correlates with some general shifts during this election, including the bump the green party got during the debate controversy and now the rise of the NDP as a serious contender, or at least a possible Liberal spoiler, in this election.

Today’s data follows the same format and configuration as my other two post:

The Set Up

The Search Terms and Filters are very important when using Google Insight. As I found in my initial post “Searches for Canadian Political Parties and Leaders: Google Insights Data” it was very important to include specific search terms people might use, while excluding search terms which brought in extraneous data. The search terms I constructed were based on ballancing these two concerns. As before, I am including data from all of Canada’s regions and from the past 30 days.

The Interest Over Time graph:

Interest Over Time

A couple things of interest here. One is that the green party post-debate controversy bump has continued, and the total frequency of searches for the green party and their leader have only fallen bellow searches for the Liberal Party and their leader on three days. More interesting, I think, is that since September 17th the NDP and Jack Layton have been in the Canadian political search rave. While this may relate to how connected Canadians and Google user’s skew politically it should be noted that before the 17th the Conservative and Liberal parties were consistently number 1 and 2 in terms of search frequency.

Now the regional interest graph, this time focused on the NDP:

Regional Interest Graph

In general I think Google’s data here seems to reinforce other things I have been heading. The NDP seems strongest, however, in provinces where the Green party does best. I think it would be more interesting to focus on individual provinces like British Columbia and see if Google’s data for is deep enough to actually look into city by city search trends. If it is deep enough to allow such analysis, at least for populated provinces, it could be used to attempt to predict which way ridings might go on election day.

Finally, the same caviets that I wrote in my first post apply here as well.

Note: I have a new post on Fritz Kahn here: The Cycles of Virtue and Substance: Fritz Kahn and the Chemical Cycles of Man and Machine

Fritz Kahn is an enigmatic figure. Born in 1888 in Germany, Kahn trained as a gynecologist but was forced to close his medical practice in 1933 because of the rise of National Socialism and the passing of anti­-Semitic legislation. Kahn participated in the publication of more than twelve books on biological and medical topics during his lifetime, many of which would be translated into English, Dutch, French, Spanish, Portuguese, Italian, Chinese, Indonesian and Finish. Apparently smuggled out of Europe in 1940, Kahn likely returned to Europe by 1949 where he would die in 1969. This short biography is almost all that is publicly available about Kahn’s life.

Man as Industrial Palace - Der Mensch als Industriepalast

Kahn produced illustrations that drew a direct functional analogy between human physiology and the operation of contemporary technologies, especially industrial machines and commonly encountered household machines. I use the term ‘produced’ quite literally. Kahn — like most writers of  anatomy texts — oversaw the work of many different illustrators. In his  earlier publications individual artists could be identified by their signatures. Following his emigration to the United States, however, Kahn trademarked ‘his’ style and placed a ‘FK’ stamp over the artists signature (1).

Kahn’s illustrations can be used to investigate contemporary reactions to modernity: the tension between reductionism and holism, the popularity of evolutionary and comparative thinking, the application of science to health, work and reproduction, as well as the professionalization of science. These themes were visually embedded in the illustrations that Kahn and his illustrators produced by Kahn.

The Weimar Republic (the turbulent German democracy that existed between the end of World War One and the rise of National Socialism; 1919-1933) was an opportune time for science popularization and was host to an unprecedented growth of printing technologies and media generally. The publishing house “Kosmos” (named for Alexander von Humboldt’s 1885 publication of the same name) who Kahn published under, represented the middle-­class bourgeois market for popular science. Published by the “Society for Nature Lovers,” Kosmos released regular monthly periodicals as well as book supplements throughout the year. Kosmos reached a peak of over 100,000 members during the Weiman Republic and still exists today publishing science books and science kits for young people (2).

KosMos

The Man-Machine Analogy and Functional Realism

This post focuses on Kahn’s last European publication – “Man in Structure in Function” — ­ which was subsequently translated for Alfred Knopf and published in the United States in 1943 where it went through two printings in its first year. Simultaneously published by Ryerson University Press in Canada, “Man in Structure and Function” is still widely available in university libraries accross north America (3).

The first image of the book – refered to in the first sentence – introduces two of the primary themes which Kahn utilizes throughout: the functional analogy between man and machine and a hierarchy in which technology is depicted as superior to man. In the image a silhouetted male figure is set inside a cut­out drawing of a train locomotive; both man and locomotive have specific internal parts drawn, which are compared functionally. In
the man there is the heart, lungs, digestive system, respiratory system and arm muscles, which are contrasted visually with the locomotive’s furnace, ash, air intake and exhaust pipes, and drive system (Man and Machine).

Man and Machine Exhibit Far­reaching Similarities

Visually these elements are connected by being located at the same level and by diagrammatic lines which connect the sub­systems of the locomotive with the organs of the man. Thus the arm muscles of the man are linked with the drive train of the locomotive, the digestive system with the furnace. Indeed, even the smoke rising from the locomotive  mingles indistinguishably with the man’s exhaled breath. The accompanying text explains the functional analogy explictely:

“Man   and   machine exhibit   far­reaching   similarities   (Fig. 208). Both derive their energy from the combustion of carbon (C), which they obtain from plants. Man, the weaker machine, utilizes   fresh   plants   for   fuel,  while   the   locomotive, a stronger   machine,   uses   fossilized   plants   in   the   form   of coal.” (4)

This strategy of making functional comparisons between organs and machines could be described as functional realism. Cornelius Borck notes that Kahn’s illustrations also display topographical realism in their careful placement of machine analogues in their ‘accurate’ anatomical locations (5).

The Auditory Ossicles in our car function like the Driving Mechanism of an Automobile

See and Say 'Auto'

The analogy between functional anatomy and technology was not exactly new. Contemporary art styles also dealt with modernity and made use of machine-­man amalgams: Dada, Constructivism, Machine Art and New Objectivity all dealt extensively with man­ machine amalgamations. Sergiusz Michalski notes that Neue Sachlichkeit (New Objectivity) the dominant art movement of the 1920s and 1930s, correlated “humankind with the function procedures and requirements of machines” concluding that “their pictures express the hope that it will be possible to govern and control this world” (6). In part it was the iconic status of the man­-machine analogues that made Kahn’s illustrations possible.

Bauhaus

Raoul Hausmann - Tatlin at Home

Metropolis

What seems to be unique is how explicitly and literally Kahn uses the man­-machine analogy as a pedogological strategy. Over and over Kahn represents human functional anatomy as machine­-analogues. A pump is a stand in for the heart, pipes stand for veins, conveyor belts for the digestive system, and telephone exchanges for neural functions. In the illustration “An Adult says ‘auto’” (See and Say ‘Auto’) which combines the ‘processes’ for seeing, recognizing, and saying ‘auto’. Kahn himself remarks on this strategy:

“If these three processes are united in a single picture and the component elements of these processes are represented by means   of   a well­known technical means we obtain a picture like [figure 2]” (7).

Kahn uses these functional analogies as a bridge to naturalism by frequently returning to images of structural realism which he uses rhetorically to bridge the functional­structural divide. For example, the following text accompanies an structural illustration (Microscopic Structure of the Cerebellum) of a cross­section of the cerebral cortex:

“They are life, knowledge, feeling, and enjoyment; they are the I, the personality. We is the sum total of the cortical cells of our brain; our I is the   giant   concert   which   this greatest of all radio stations, this station of microscopic tubes,   antennas,   coils,   condensers,   and   transformers, broadcasts as thought and feeling to the microcosmos of the cell body, and as word and deed to the wide world” (8).

In this excerpt Kahn maintains the technological analogies but transposes them onto a structural image of the cerebral cortex.

Microscopic Structure of the Cerebellum

Olfactory and Visual Cortex

Efficiency and Eugenics

One of the prominant themes of early 20th century science is the changing relationship between science and daily life. Increasingly scientific methods and rhetoric became important parts of social and political movements. One example of this is the “science of work” which was introduced into training programs and vocational testing as part of the ‘rationalization’ of industry. Included in the science of work was the fields of psychotechnics, work psychology and efficiency (9).

Kahn introduces the topic of the science of work as a core concept in neuroanatomy — placing it rhetorically as a basic science — right after the speed of neural transmission and before the section on the neuron itself. Under the sub­section “The Personal Equation” Kahn places a pair of illustrations entitled “The Speed of Reaction.” In these images a pair of silhouetted crane operators are depicted moving a ’scoop’ to a ‘goal’. The first image (The Speed of Reaction I) is accompanied by the following description:

“In the nervous system of a talented person the reaction eye­-brain­-arm… takes 3/10 second. If such a person works as a driver of a crane he directs the scoop to its goal along the shortest possible possible path.”

The path of the ’scoop’ is traced visually through the air to show the reader how efficient the ‘talented man’ it. Further reinforcing this is an ‘objective’ clock­type measuring device that ‘records’ the speed of the man’s reaction visually.

The Speed of Reaction I

In the second image [The Speed of Reaction II] another figure with a  significantly less flattering profile operates the crane; here the path traced by the ’scoop’ takes loops around itself taking a longer path than the case of the first crane operator (it should be noted, although I am not going to discuss it here, that the ’science of work’ and ‘efficiency’ were often euphemisms for eugenics and race science). Kahn explains that in this case the:

“nerve   impulse   takes   more   than   3/10   second   to   leave   the brain.  If  such a  person works  as a  crane­driver, he  direct the   scoop   along   a   zigzag   path   so   that   he   loses   time   and performs   less   work.   If   this   continues   for     a   considerable period…   it   is   obvious   that   it   amounts   to   a   considerable loss of time and energy.”

Here we can see a visual representation of how individual differences in the speed of the nerve impulse is said to result in lost productivity. Note that in the first image the man in the background stands on a significantly lower pile. Kahn concludes that:

“This   man,   who   should   never   have   become   a   crane­driver,   is one   of   the   hundreds   of   thousands   who   have   chosen   an    occupation at random without an test of their abilities, and now   performs   their   duties   as   best   they   can.   Employment psychology,   recognizing   this   fact,   rejects   applicants   whose abilities do not measure up to the standards required for a certain   position.   In   doing   so,   however,   it   takes   into consideration   not   alone   intelligence   but   also   special abilities.” (10)

The Speed of Reaction II

Psychotechnic aptitude testing was part of the science of work and efficiency, applied fields which used scientific methods to improve productivity that were especially popular in Germany, where they became a “virtual craze” during the post­war years. These included psychotechnics, industrial psychology and physiology as well as aptitude testing and vocational guidance. Industrial Psychology is one field born from this period that is still very active today, as anyone who works with a Human Resources Department can attest (11).

Like science popularization, such fields were not unique to any particular ideology. Rabinbach writes that: “on   all   points   of   the   political   spectrum   ‘Taylorism   and Technocracy’   were   the   watchwords   of   the   three­pronged idealism: the elimination of economic and social crisis; the expansion   of   productivity   through   science;   and   the enchantment of technology” concluding that “productivism, in short, was politically
promiscuous” (12).

One question, however, surrounds Kahn’s inclusion of such obvious images and references to work science: by the time Kahn was writing “Man in Structure and Function” the work­ sciences has been in decline for almost a decade. During the 1930s work science fell from favor and new romantic and authoritarian approaches preaching ‘joy in work’ and ’social harmony’ replaced them as the National Socialist Party gained power and influence (13). Yet Kahn still chooses to include these images. One possibility is that Kahn was simply reusing materials from earlier publications. A more interesting hypothesis, however, is that Kahn purposely included the (potentially) anti­-romantic and authoritarian ‘politically promiscuous’ sciences in opposition to the new authoritarian model.

Femininity and the Limits of the Industrial Analogy

Throughout “Man in Structure and Function” Kahn maintains a hierarchy between nature (represented by man) and technology (represented by industrial machines) in which technology is depicted as superior to nature. The very first sentence and illustration of the book compares man to a locomotive in terms of oxygen consumption and the carbon cycle (Man and Machine). In another illustration entitled “The speed of though” the speed of a nerve impulse is compared to the speed of an telegraph signal and an air plane. We are told that: “In earlier times the rapidity with which an impulse was conducted along a nerve fibre was considered the quintessence of speed… This idea has been superseded, however, by the accomplishments of modern technology” (14).

The Speed of Thought

This hierarchy is reversed, however, in two specific topics: the female reproductive system – specifically birth – and in the concluding chapter on “Sexuality and Human Life”. Compare the language with which Kahn introduces birth with his above comments on the speed of neural impulses:

“Imagine that someone has been able to grow and apple in a wine   bottle   and   now   wants   to   remove   the   fist   sized   apple through   the   narrow   bottle­neck   without   damaging   it.   This appears technically impossible and it actually is impossible. Biology,   however,   is   not   technology.   The   uterus   is   able   to  accomplish the apparently impossible

Here Kahn reverses the hierarchy he has established; man (and biology) are now superior to technology. Not only that, but Kahn seems to draw a sharp line here between biology and technology. Previously the two were related, almost different models of the same processes. Now, however, “Biology… is not technology” and is capable of things “technically impossible”.

Female Sex Apparatus

The final two images of the book also contribute to breaking down this hierarchy. In the final chapter “­Sexuality and Human Life” ­ Kahn explicitly breaks down his nature-­technology hierarchy and re-­enfranchises man (and nature) as superior to technology. The first image, entitled “The False Ideal” depicts an elderly woman encased inside a elevator­like box in a room crowded with people. The text explains that this is “great­-great­grandmother… awakened for ten minutes on the celebration of her two hundredth birthday” (16). Set across from this image is a close­-cropped  photo entitled “The True Ideal” in which an elderly couple embrace.

The False Ideal

It is not difficult to imagine hypothetical reasons why Kahn would choose to abandon the previous hierarchy and machine analogy at this juncture. It is possible that reproduction, especially its more ‘mysterious’ (I.e. female) aspects were not culturally suitable to representation as machine analogues. It is also possible that the German glorification of the body may have contributed to seeing reproduction and a uniquely ‘perfect’ aspect
of biology. Furthermore, Kahn may be rhetorically switching hierarchies in order to return his readers to a safe imaginative perspective at the close of the book.

The True Ideal

The Wrath of Kahn and Contemporary Body Machines

In this short post it has only been possible to glance at some of the many themes and tensions embodied in Kahn’s illustrations. There are many other questions that have been left unanswered: What was Kahn’s view on race debates of the time? What were Kahn’s political and social beliefs and how did these affect the images he produced? What were his ontological and epistemological beliefs about the divide between man and machine?

The wrath of Kahn (how could I resist) is that despite the antiquated and naive appearance of his illustrations and their obvious epistemological limits it is not entirely clear that contemporary representations of functional anatomy — ­­ especially neuroanatomy — ­ are significantly different. Computers (a technology that we are familiar with) have replaced machine analogies and hard­working homunculi in both popular and academic neuroanatomy. Meanwhile, functional neuroanatomy often simply uses coloured lines to depict functional properties, a method I call “magic-­marker realism” for the way these colourful lines are meant to somehow depict complex underlying physiological events.  The antiquated nature of Kahn’s illustrations makes these questions about contemporary representations troubling, because it suggests that our own images of functional anatomy are as historically and culturally situated and dependent as the locomotive and the switchboard operator analogies of the 1920s and 1930s.

Wordle is a new visualization toy that creates word clouds from blocks of texts (blog posts, books, stories, speeches, etc.) in which the size of a word represents that word’s relative frequency compared to other words in the text. I’ve been playing with Wordle for the last couple days, mostly using texts from the history of psychology (old journal articles) as preparation for a possible future thesis project. Yesterday I decided to use the opening election speeches from three of Canada’s national political parties, the Conservative Party of Canada, the Liberal party of Canada, and the New Democrat Party. I have not included anything from the Green Party of Canada or the Bloc Quebecois because I could not find comparitive material.

Stephen Harper, Sept. 7. 2008 – Election a choice between certainty and risk:

Stephane Dion, Sept. 7, 2008 – A new path for Canada:

Jack Layton, Sept. 7, 2008 – Its time to choose change:

Conclusions:

• I do not pretend that these kind of graphs meen anything conclusive.
• Its interesting how prominant the words “promised” and “delivered” are in Harper’s speech.
• All three speeches use variations of Canada and Canadians extensively.
• Jack Layton’s speech seems to be chanelling Obama a little, with prominant use of the words “change” “believe” and “can”. It would be interesting to do a comparitive word cloud and see just how close they really are.
• That said, Harper’s speech seems to be better ballanced, word frequency wise, and contain more “issue” words than either the NDP or Liberal party speeches.

The Canadian Green Party seemed to have enjoyed a significant bump in it’s online (and offline) profile during the debate controversy, so I figured it would be interesting to take another look at the Google Insights’ data and see what effect this has had on internet searches for political parties and leaders. As you can see bellow, the (now reversed) decision to exclude Green Party leader Elizabeth May from the leader’s debate resulted in a significant surge in searches for the party and it’s leader.

First, the set up, using the same settings as my previous Google Insights search:

The key:

The 30-day Interest Over Time graph:

As you can see, according to Google’s data, searches for the Green Party, et. al. surged along with the other parties between September 6th and 8th, and then surpassed the other parties between the 8th (when the decision to exclude the Green Party from the Debate was announced) and 9th and as of September 10 they remain in first place. The afternoon of the 10th it was announced that Elizabeth May will be allowed to participate in the debate.

Finally, the Regional Interest graph, focused on the Green Party and Elizabeth May:

Thoughts:

• Searches for the Green Party of Canada and Elizabeth May continue to be strongest in Nova Scotia, Ontario, Manitoba, and to a lesser degree, British Columbia.
• I am not sure why Saskatchewan is not showing any search data right now, it may be because Google has not yet collected all the data yet. I’ve noticed a two to three day delay on Insight data.
• It seems that the regions with the strongest Green party searches are also home to the strongest NDP searches, although I have not figured out a way to quantify that data yet and test it.
• It will be interesting to see how quickly the Green Party looses its new first place status (assuming it does) as the election moves forward.
• That said, the same caviets i had about my orginal Insights search apply here as well.
