A tenth of a second took longer than a tenth of a second to read though each letter or word in some cases might have taken that long to perceive For a revised dissertation I think she has definitely looked at and mentioned every French text from the latter half of the 19th century with regards to observation or most interestingly the personal euation While 20th century science has tried to rid itself entirely of personality or a range of ways of perceiving things it hasn't always been this way The two things that made this book most interesting to me were the discussion of implications for modernity which were not developed enough and the relationship of Bergson to Einstein on time and relativity Canales claims at the beginning of this book that she has two main concerns one practical that relates the scientific and the technological such as the speed of thought or a cinematographic instant The second concern was broadly philosophical references to this short period of time were part of a general inuiry into time temporal development and sensory experience By extending these investigations we can begin to use the tenth of a second as a way to rethink much longer historical periods 2 As I was pulled into this book the photographs of Eadward Muybridge on the cover in which the illusion of movement appears smoothly pointed to the simplicity of how an illusion or a reality or even death itself psychologically physiologically or physically can be reduced to reaction times For instance Léon Lalanne told a story about a Swedish king being hit by a mortal blow while moving his hand toward his sword shaft Lalanne's Note sur la durée de la sensation tactile The lag time between stimulus and response not only challenged Cartesian mind body dualism but also the relationship of politics to science as in the Hobbes vs Boyle discussion of the existence of a vacuum During the industrial revolution the relevant problem for philosophy of science was no longer principally based on long standing uestions of objectivity or matters of fact and subjectivity or matters of concern instead scientists and philosophers confronted the problem of observations that varied among and within individuals 9 Here the temporality of cognition itself a post Kantian problem she calls it becomes modeled on a camera in place of a mirror Errors were committed in astronomy metrology and physics due to the split second variations among perceivers In place of Cartesian or Lockean static forms of perception which should sound like an image theory Canales begins to read modernity through Bergson as having a type of observation that worked through time cinematographic than photographicthe body could be modeled as an instrument 10 But bodies vary and even nerve endings challenge our very perceptions Psychology and sociology of science butted heads with physics and with astronomy even the arts since the entire notion of measurement for example the speed of nervous transmissions nerve lengths and the speed of thought was in uestion What is modern progress and how do we measure such a thing? Instead of studying the tenth of a second in modernity my aim is to understand the tenth of a second as modernity she writes 14 That is the theme of her book to come on my blog From the history of science tracing the effect the sudden ability to measure in tenths of a second had on neurology and physiology physics and astronomy photography and cinematography and eventually relativity Dry academic and interesting take on the debate and philosophicalscientificpsychical implications of the tenth of a second from the mid 19th into the early 20th century
