Ever since Russell gave his paper "On the notion of cause" in 1913, the role of causality in physics has been hotly debated. Is the concept of causation absent from modern physical theories, as Russell suggested? Don't we need causal notions to account for e.g. radiation asymmetry? And can physical explanations really do without causes? In his forthcoming book "Causal Reasoning in Physics" (Cambridge University Press), Mathias Frisch makes a strong case for the anti-Russellian claim that causal notions and causal inferences figure prominently in physics. The aim of this workshop is to discuss his ideas and related topics.
