Exploring the Past and Future of Our Planet: Not Bit-by-Bit but All at Once     

Keith C. Clarke 《The Professional geographer》2013,65(3):320-324

Understanding the Changing Planet lacks the spark of wonder and synthesis that initially attracted me into geography. Its structure around compelling questions reflects disciplinary fragmentation and the model of interdisciplinary science favored in the late twentieth century. It is suggested that geography can move beyond the “big tent with three poles” approach, to a twenty-first-century hyperdisciplinary model where content, science, analysis, and synthesis blur and a new bottom-up science can emerge. In this science, new theory and even grand unified theory might be possible. As discussed in Understanding the Changing Planet, the Web and the emergence of volunteered geographic information are examples. This would make study of the whole earth and its systems “a respectable object for scholarly efforts.”  相似文献   

用非线性动力学的观点分析形变异常与干扰初探     

薄万举 《大地测量与地球动力学》1992,(4)

在形变资料的分析处理中,如何分辨干扰与信息始终是一个难题。本文利用非线性动力学的基本概念,对一些异常资料重新进行了剖析,得出了一些新的认识,某些以往认为属于干扰所致的变化从理论上很可能就是我们想要捕捉的形变异常信息。本文的结论对用形变资料进行地震预报可能有一定的参考意义。  相似文献
