Material Sight: A Sensorium for Fundamental Physics
Often our attempts to connect to the spatial and temporal scales of fundamental physics - from the subatomic to the multiverse - provoke a form of perceptual vertigo, especially for non-scientists. When we approach ideas of paralysing abstraction through the perceptual range of our sensing bodies, a ‘phenomenological dissonance’ can be said to be invoked, between material presence and radical remoteness. This relational dynamic, between materiality and remoteness, formed the conceptual springboard for 'Material Sight' (2016-2018), a research project based at three world-leading facilities for fundamental physics, that brought to fruition a body of photographic objects, film works and immersive soundscape that re-presented the spaces of fundamental physics as sites of material encounter. The research was premised on a paradoxical desire to create a sensorium for fundamental physics, asking if photography, film and sound can embody the spaces of experimental science and present them back to scientists and non-scientists alike, not as illustrations of the technical sublime but as sites of phenomenological encounter. This article plots the key conceptual coordinates of 'Material Sight' and looks at how the project’s methodological design – essentially the production of knowledge through the 'act of looking' – emphatically resisted the gravitational pull of art to be instrumentalised as an illustrative device within scientific contexts

Non-universality in Micro-branching Instabilities in Rapid Fracture: the Role of Material Properties
In spite of the apparent similarity of micro-branching instabilities in
different brittle materials, we propose that the physics determining the
typical length- and time-scales characterizing the post-instability patterns
differ greatly from material to material. We offer a scaling theory connecting
the pattern characteristics to material properties (like molecular weight) in
brittle plastics like PMMA, and stress the fundamental differences with
patterns in glass which are crucially influenced by 3-dimensional dynamics. In
both cases the present ab-initio theoretical models are still too far from
reality, disregarding some fundamental physics of the phenomena.Comment: 4 pages, 6 figures, PRL submitte
