Fifth year LPS graduate student Sam Fletcher will present research at an upcoming workshop on reduction and emergence in physics, hosted by the Munich Center for Mathematical Philosophy, at Ludwig-Maximilians University in Munich, Germany. Fletcher's paper concerns how to understand the relationship between general relativity, our current best theory of space, time, and gravitation, and the older Newtonian theory of gravity. He argues that previous work on this relationship has rested on an unacknowledged assumption regarding when certain sequences converge, and seeks to develop ways of either justifying or weakening this assumption.
