AbstractThis chapter studies how unpredictable change is understood through concepts like of fractals, chaos theory, catastrophe theory, perfect storms, and climate models in feature films from 1982 to 2019, both as narrative themes and as spectacular simulation-based animations. Positing a particular mode of visual effects spectatorship, the chapter observes how narrative, theme, and spectacular images represent these concepts in congress. Over the period surveyed, these representations shift from sublime overwhelming images of disastrous events to more recent examples that embrace chaos as a source of creativity and knowledge.

We applied catastrophe and chaos theory to analyze the traffic nonlinear characteristics of expressway condition. Catastrophe theory was generally used to explore the mathematical relationships among the traffic data collected from highway conditions, which could not be appropriate for the urban expressway conditions. Traffic flow data collected from the 3rd ring road expressway in Beijing was used to build flow-density model and speed-density Greenshields model. Then the density was discussed based on the traffic wave speed function with cusp catastrophe theory; in particular, density conditions on median lanes and shoulder lanes were deeply discussed. Meanwhile the chaotic characteristics were analyzed based on the traffic temporal sequence data collected from 29 detectors located at the 3rd ring road expressway, and C-C method was used to reconstruct the phase space and the largest Lyapunov exponents were estimated by Wolf method and the small data sets method. The results indicated that the traffic operation catastrophe density on the median lanes was a bit higher than that on the shoulder lanes; additionally chaotic characteristics obviously existed in the local corridor composed of 29 detectors in the 3rd ring road expressway traffic flow system.

Educational Films

Academic history has begun only relatively recently to study films as historical sources, and thus far it has focused principally on feature films to the exclusion of nonfictional cinema, despite the use of educational films for propaganda as early as the interwar period. This essay examines the extent to which educational films of this period employed a range of techniques to reach their viewers and encouraged them to take the film’s argumentation on board. Categorizing these techniques as either narrative strategies or visual effects, we contextualize their use by taking the film Die Weltgeschichte als Kolonialgeschichte (“World History as Colonial History,” 1926) as an example.

Simulation Based

Climate simulation-based scenarios are routinely used to characterize a range of plausible climate futures. Despite some recent progress on bending the emissions curve, RCP8.5, the most aggressive scenario in assumed fossil fuel use for global climate models, will continue to serve as a useful tool for quantifying physical climate risk, especially over near- to midterm policy-relevant time horizons. Not only are the emissions consistent with RCP8.5 in close agreement with historical total cumulative CO2emissions (within 1%), but RCP8.5 is also the best match out to midcentury under current and stated policies with still highly plausible levels of CO2emissions in 2100.
