The kilogram prototype is an object manufactured in late nineteenth century to serve as the standard unit of mass worldwide. Since then, the kilogram definition has been determined by this unique object, making it a peculiar case in metrological studies. However, after realizing that the prototype’s mass was unexpectedly changing, scientists are seeking a new way to define the kilogram in pure mathematical terms.

More about this publication?
  • Philosophy of Photography is a new peer-reviewed journal devoted to the scholarly understanding of photography. It is not committed to any one notion of photography nor, indeed, to any particular philosophical approach. The purpose of the journal is to provide a forum for debate on theoretical issues arising from the historical, political, cultural, scientific and critical matrix of ideas, practices and techniques that may be said to constitute photography as a multifaceted form. In a contemporary context remarkable for its diversity and rate of change, the conjunction of the terms 'philosophy' and 'photography' in the journal's title is intended to act as a provocation to serious reflection on the ways in which existing and emergent photographic discourses might engage with and inform each other.
