<p>The scientific community is beginning to see how our environment reacts to changes on an unprecedented time and space scale with the utilization of small Unmanned Aircraft Systems or sUAS.  These new observation platforms can be utilized for flood forecasting, local weather forecasting, monitor wildlife, improve hurricane forecasts and this the tip of the iceberg. This technology is a new tool that will allow the scientific community to observe the environment on time and space scales that are unprecedented.  This particular talk will primarily address the future of these observing platforms as it relates to advancing the atmospheric sciences. UAS’s are rapidly becoming the new technology that can acquire low-level environment information more frequently, in support of higher-resolution model forecasts of severe thunderstorm and tornado potential, improvement in  Environmental Model Prediction, provide environmental  information to provide better support  the spread of wildfires and smoke, as well as wildfire imagery for Incident Command and more complete/accurate storm damage surveys.  One of the end goals would be to have  a nationwide network of sUAS providing near-continuous observations of thermodynamic parameters, NDVI, surface sensible heat and wind speed and direction. Most of these observations are being done on a regular basis and some will be attainable in the future as technology progresses and National Airspace becomes more accessible. </p>

The article deals with the problems of introducing of time, time changes and the time-place relations as well. Artistic time is distinguished by belonging of an artistic time to the past in the artistic text, and in epos texts as well. In such kinds of texts one can meet with the changing of situations and various forms of substitutions of grammatical time. Speech moment can be used in defining of criteria for the present, past and the future times in epos texts. And speech moment is being connected with the physical time. Grammatical time comes into effect as a result of time pass components of physical time changings of course. Key words: time, place, epos, artistic time, grammatical time

In her article 'Othering Time: Strategies of Attunement to Non-Human Temporalities,' art curator and researcher in the field of art and ecology Alice Smits delves into artistic practices that tune into deep time and non-human time zones. Starting from the viewpoint that our current ecological crisis is in need of developing an ethics of care towards generations far into the future and life forms extremely different to ours, she discusses art and aesthetic knowledge as particularly well suited for experimentation with new stories and sensibilities about our place in time. Making use of geologist Marcia Bjornerud's concept of 'timefulness,' the article focuses on several art projects by Rachel Sussman, Katie Paterson and Špela Petrič, whose works engage in developing a more time-literate sensibility that aims to understand how our everyday lives are shaped by processes that vastly predate us. Underlining changing ways of understanding of time and space by opening up to what is referred to in the title as 'othering time,' art opens up as a discourse in its own right that can interrogate the sciences as a specific epistemological framework that is in need of revision. The author concludes with a few references to how these artistic practices change her own curatorial practice.

Abstract When moving, the spatiotemporal unfolding of events is bound to our physical trajectory, and time and space become entangled in episodic memory. When imagining past or future events, or being in different geographical locations, the temporal and spatial dimensions of mental events can be independently accessed and manipulated. Using time-resolved neuroimaging, we characterized brain activity while participants ordered historical events from different mental perspectives in time (e.g., when imagining being 9 years in the future) or in space (e.g., when imagining being in Cayenne). We describe 2 neural signatures of temporal ordinality: an early brain response distinguishing whether participants were mentally in the past, the present or the future (self-projection in time), and a graded activity at event retrieval, indexing the mental distance between the representation of the self in time and the event. Neural signatures of ordinality and symbolic distances in time were distinct from those observed in the homologous spatial task: activity indicating spatial order and distances overlapped in latency in distinct brain regions. We interpret our findings as evidence that the conscious representation of time and space share algorithms (egocentric mapping, distance, and ordinality computations) but different implementations with a distinctive status for the psychological “time arrow.”

Led by the Meteorological Service of Canada, atmospheric research in Canada underwent a period of rapid growth after the end of the Second World War. Within this federal organization, and in response to operational challenges and staff shortages, there were significant investments in basic research and in research oriented toward external users within Canada. Specifically, new policies and programs were put in place to enable the organization to gain legitimacy within the scientific community and within the federal government. New links with stakeholders and, more importantly, the development of explicit policies to guide research were a prime focus. These formalized strategies for pursuing two parallel types of research generated some internal conflict, but also helped form a common scientific identity among personnel. There were concerted efforts to disseminate research products and reinforce links both with the scientific community and with external users of meteorological and climatological research. Borne out by quantitative data, this science policy–centered history sheds light on the development of research and research specializations in the field in Canada. Most importantly, it provides insight into the global postwar expansion of the atmospheric sciences, which is strongly tied to national contexts. Indeed, the quest for legitimacy and the close connection to government priorities is central to the history of the atmospheric sciences in the twentieth century. More broadly, this case study points to a possible new conception of government science driven by political, bureaucratic, and scientific imperatives, as a means to shed light on scientific networks and practices.
