‘Pou maumahara’, ‘the memory place’: Remembrance and material cultures of colonial conflict at the Auckland War Memorial Museum Tāmaki Paenga Hira

open access: yesHistorical Encounters: A Journal of Historical Consciousness, Historical Cultures, and History Education, 2023
This article explores how material objects reveal patterns of remembrance in the public histories of the nineteenth-century New Zealand Wars fought between British regiments and colonial forces and Māori hapū and iwi (tribal groups). It is based

On the creation of a photon by an electromagnetic wave ball

open access: yesScientific Reports, 2023
Recent literature has shown, theoretically as well as experimentally, that while a beam splitter does not split a single photon, it nonetheless divides the electromagnetic wave into transmitted and reflected, with both containing energies.

Is the Light too Light? [PDF]

open access: yes, 2012
The gravitational interaction of light is analyzed considering its dual characteristic nature, i.e., as an (electromagnetic) wave or as a particle (photon). Considered as an electromagnetic wave, the light can be source of gravitational waves belonging to the larger class of exact solutions of Einstein field equations which are invariant for a non ...

Controlling Light Harvesting with Light [PDF]

open access: yesJournal of the American Chemical Society, 2016
When exposed to intense sunlight, all organisms performing oxygenic photosynthesis implement various photoprotective strategies to prevent potentially lethal photodamage. The rapidly responding photoprotective mechanisms, occurring in the light-harvesting pigment-protein antennae, take effect within tens of seconds, while the dramatic and potentially ...

Open Access Sandpiles of Dignity: Labor Status and Boundary-Making in the Contemporary American Prison

open access: yesRSF: The Russell Sage Foundation Journal of the Social Sciences, 2020
This study investigates discursive strategies through which prisoners seek dignity. In particular, it turns toward the role of penal labor in such pursuits. Drawing on eighty-two in-depth interviews and eighteen months of ethnographic fieldwork conducted

Contrefaire l’art ou contrefaire la nature : l’analogie artistique pour la restauration écologique

open access: yesCybergeo, 2009
Andrew Light examines the debates on restoration ecology between Robert Elliot and Eric Katz. Rather than taking on their strong metaphysical distinction between nature and culture, as some critics do, he assumes it is true and then argues that it does ...

Light by light diffraction in vacuum [PDF]

open access: yesPhysical Review A, 2010
We show that a laser beam can be diffracted by a more concentrated light pulse due to quantum vacuum effects. We compute analytically the intensity pattern in a realistic experimental configuration, and discuss how it can be used to measure for the first time the parameters describing photon-photon scattering in vacuum.
