False Dichotomy

Don Ihde examines the “congenital dystopianism” shared by environmentalists, environmental philosophers, and philosophers of technology. Each group employs a “rhetoric of alarm” that connects the use of technologies with environmental degradations. Ihde calls attention to how excessive rhetorical strategies have locked us into a false dichotomy: either technological-environmental utopianism or dystopianism. The problem is that we have not yet fully diagnosed either what our technologies can or should do, or what the environmental crises actually are. So long as we continue to accept either utopian or dystopian forecasts we are unlikely to bring either technologies or ecosystems into appropriate focus. Techno-environmental problems are complex, ambiguous, and interwoven; they rarely lend themselves either to an easy techno-fix or simple solution. The hardest problem of them all is how to turn major actors in the economy green: large scale development projects and multinational corporations. The challenge for a proactive philosopher is to get on the ground floor of technological research and development in order to help figure out how to green the economy itself.

It is well known that the optical properties of multi-particle phosphor are crucial to the light performance of white light-emitting diodes (LEDs). Note that the optical properties including scattering or absorption properties for a single particle are easy to be calculated. However, due to the large computation considering the complicated re-scattering and re-absorption, it is difficult to calculate the scattering behaviors of the multi-particles. A common method to reduce the computation, which can cause unknown deviations, is to replace the multi-particle scattering properties by using the average scattering data of single particles. In this work, a cluster of multi-phosphor particles are directly simulated by the finite-difference time-domain (FDTD) method. The total scattering data of the cluster was processed as a bulk scattering parameter and imported to the Monte-Carlo ray-tracing (RT) method to realize a large-scale multi-particle scattering calculation. A polynomial mathematical model was built according to the multi-particle scattering data. An experiment was carried out for verifying the accuracy of the method in this work. The mean absolute percentages of the previous method are 1.68, 2.06, and 1.22 times larger than the multi-particle method compared with the experimental curves, respectively.
