Over fifty years ago, Erdős and Rényi proved the striking result that the structure of the size-random graph G(n, m) undergoes a phase transition as m, the number of edges, grows from less than n/2 to more than n/2. For the past quarter of a century, this phase transition has been studied in great detail, with a host of detailed results emerging, such as the size of the scaling window, and the ...

This series of lecture notes were taken for the topic class on minimal surfaces given by Professor Rick Schoen in the Winter quarter of 2012 at Stanford. We kept the pace of these lectures by dates. These lectures start from basic materials on minimal surfaces, e.g. first and second variations, and monotonicity formulae, and then discuss several curvature estimates for minimal surfaces. Afterwa...

We reconsider some important foundational problems of quantum mechanics. After reviewing the measurement problem and discussing its unavoidability, we analyze some proposals to overcome it. This analysis leads us to reconsider the current debate on our best theory, i.e. quantum mechanics itself. We stress that, after the remarkable interest and the many efforts which have lead, in the last year...
