![]() With a prism ordinary white light can be split into a spectrum that resembles a rainbow.Īlthough its significance went unrecognised at the time, the Nicol prism is now used in all polarising microscopes today. ![]() The two beams, with two different planes of polarization, are then analyzed by another Nicol prism. Polarization can be verified by rotating either the Nicol prism or the Polaroid, which is between the Nicol prism and the lens in the photograph. The tale of the whale shows how every story today is seen through the prism of individual emotions.īelow the stage is a mirror to reflect light up through the specimen and a Nicol prism can be swung in to polarise the light. Passing the light emitted by an element through a prism gives the atomic emission spectrum of the element. It was Newton who first realized that white light is made up of the colors of the rainbow, made visible through the prism. If viewed through a prism, however, there is a decomposition of the light into the colors of the spectrum, each with different wavelengths. The Venice we see here, through the prism of Scottish fantasies, is a fabled city of delight, that glass goblet as stupendous as a Titian. ![]() ![]() The white light split into different colours and each colour had been bent a different amount by the prism. Moreover-and forming the core focus of this issue-we argue that we are more and more being told about how to ‘solve’ ecological problems through spectacular environmentalisms: the spectacularised, environmentally-focused media spaces that are differentially political, normative and moralised and that traverse our everyday public and private lifeworlds.I managed to fit all the yellow nets for the pentagonal prism, pentagonal antiprism, and pentagrammic prism all on one page. As we move firmly into the so-called Anthropocene-an era defined by human-induced global environmental change, neoliberal, consumer capitalism and the unprecedented flow of media, knowledge and communication-how is it that we know about the environment? More specifically: how is it we know about human-environment relationships-those tension-filled, ever-present, often-obscured, but inescapable relationships that are most likely overlain by some form of capitalist social relations? How do we know about ecological destruction embedded in these current human-environment relationships? How do we know what to do about the increasingly solid spectres of climate change and irretrievable biodiversity losses as well as the ordinarily polluted cities and fields many live in but count on for survival? As we and the authors of this special issue of Environmental Communication contend, given the growing prominence of media and celebrity in environmental politics, we now increasingly know about the environment through different forms, processes and aspects of the spectacle and, in particular, the spectacular environments of a progressively diverse media-scape. ![]()
