The collection of articles in this Special Feature is part of a larger project on “Forecasting Societies’ Adaptive Capacity to Climate Change” (an Advanced Grant of the European Research Council to Wolfgang Lutz). In investigating how global change will affect population vulnerability to climate variability and extremes, the project aims to help develop strategies that enable societies to bette...

Negative masses, even if isolated, imply self-acceleration, hence a catastrophic world. Abstract The conjecture of the existence of negative masses together with ordinary positive masses leads to runaway motions even if no self-reaction is considered. Pollard and Dunning-Davies have shown other constraints as a modiication of the principle of least action and that negative masses can only exist...

Professor Zeide decries Popper’s view (Zeide 2010) of science. . . the view that science must be based on falsification rather than verification: scientific theories can be decidedly falsified, but never inductively verified : e.g. one negative instance (a black swan) is sufficient to reject a hypothesis (that all swans are white), while no number of white swans can prove it. Professor Zeide sa...

In the early 1980s, a method for controlling blast vibrations other than by modifying the Scaled Distance came into use. Research studies had indicated that blast vibration could be simulated by detonating a signature hole with the vibration monitored at critical locations, and then using a computer to superpose the waveforms with varying delays. By choosing delay times that create destructive ...
