Relativistically invariant extension of the de Broglie-Bohm theory of quantum mechanics
We show that quantum mechanics can be given a Lorentz-invariant realistic
interpretation by applying our recently proposed relativistic extension of the
de Broglie-Bohm theory to deduce non-locally correlated, Lorentz-invariant
individual particle motions for the Einstein-Podolsky-Rosen experiment and the
double-interferometer experiment proposed by Horne, Shimony and Zeilinger.Comment: Revised version thanks to the referees comments. 4 pages, 4 figure
Forget Photography: The Arts Council and the Disappearance of Independent Photography in Neoliberal Britain.
This paper starts from the perspective that for some time we have been living with photography’s afterlife in which contemporary photography is a ruined territory populated by archaic knowledge practices. The way out of photography explored in this paper is through forgetting the spectral presence of photography in order, on the one hand, to see the new conditions of the image and on the other, to witness the trauma of photography’s several deaths. This is achieved by a trick of adopting the future present from which photographic knowledge practices of collection, exhibition and archiving appear as discontinuous with the present and capable of cold case reinvestigation. The art museum has absorbed photography through a process of modernist purification, continually expunging the hybrids of the contemporary image and hence, paradoxically, admits not a medium capable of examining the present, but photography as heritage.
In November 2014, Tate released a press statement announcing its ‘continuing commitment to photography’. Like a guilty secret, the phrase introduces a note of doubt on the very thing it claims to have, a commitment to photography, as if Tate knew there was a whispering campaign which said, ‘Tate has never been committed to photography’. Photography in Britain, under the odd title ‘independent photography’ delineated a category of documentary photography distinct from the commercial and industrial. Independent photography was also considered distinct from photography in contemporary art and was championed and supported by the Arts Council of Great Britain through a photography committee established by Barry Lane. Lane built up considerable influence within Visual Arts at the Arts Council, with an increasing annual budget to support independent photographers and award grants to independent photography and galleries. British independent photography was forged by the consequences of deindustrialisation and the callous support of a Conservative led state, which was resisted by communities and trade unions and led to social strife and displacement. This was the context in which renewed social documentary and community photographic practices emerged, which were disdained by the British art establishment. Barry Lane left the Arts Council in 1995 as a consequence of its decision to dissolve the photography panel, annexing its budget to visual arts on the very argument that there was no longer any distinction between photography and art. Thus, one obstacle to admitting photography to the art museum had been removed.
Forget Photography Chapter 1
Forgetting photography attempts to develop a systematic method for revealing the limits and prescriptions of thinking with photography, which no amount of revisionism of post-photographic theory can get beyond. The world urgently needs to unthink photography and go beyond it in order to understand the present constitution of the image as well as the reality or world it shows. Forgetting photography will require a different way of organizing knowledge about the visual in culture that involves crossing different knowledges of visual culture, technologies, and mediums. It will also involve thinking differently about routine and creative labor and its knowledge practices within the institutions and organization of visual reproduction
ZOMBIE PHOTOGRAPHY: WHAT IS THE PHOTOGRAPHIC IMAGE STILL DOING?
This contribution to Still Searching… is based upon the argument of my book, Forget Photography (Goldsmiths Press, 2021). The blog series is an opportunity to share some of the thinking of Forget Photography and hopefully engage in a broader dialogue about the current state of the politics of the image. The central paradox I explore is that, at a moment when photography is being technically replaced by screens, algorithms and data flow, photographic cultures are proliferating like never before. Photography is everywhere, but not as we have known it: for some time it has been an undead, a zombie, in which the established language, thinking, meanings and values of photography now stand as an obstacle to grasping the new condition. I argue that the very term photography is a barrier to understanding the altered state of the default visual image, but understanding the nature of those barriers remains a puzzle. The blog series is haunted by a pervasive problem: which is that the photographic image in computational culture continues to function as a system of universal representation, which underwrites a capitalist social formation. The persistence of a system of representation operating in a non-representational computational mode of reproduction is a paradox, and something I explore further in what transpires in this exchange. Over the course of my contribution, which is structured around three cold cases – investigations into the mortal remains of photography –, I will focus upon what keeps the logic of representation in place, how it intersects with the exhaustion of democratic politics and the inwardness of socialist organisation and how image circulation reinforces hyper-individualism and the pursuit of identity politics
Higher-dimensional tree structures
AbstractVarious generalizations of tree-characterization theorems are developed for n-dimensional complexes. In particular, generalizations of three conditions satisfied by trees T are studied: T is connected, T is acyclic, |V(T)| − |E(T)| = 1, where V(T) and E(T) denote the vertex and edge sets of T, respectively.Earlier work by Beineke and Pippert is extended in generalizing these conditions and studying which combinations of such conditions yield characterizations of the n-dimensional trees treated here
Measurement, Decoherence and Chaos in Quantum Pinball
The effect of introducing measuring devices in a ``quantum pinball'' system
is shown to lead to a chaotic evolution for the particle position as defined in
