Day One of CQC at PI
consisted of talks
until lunch, a leisurely two hour break and then an afternoon question time, which quickly degenerated into a discussion on the difference between instrumental
approaches (ie. the background independent point of view in the context of diagrammatic QM, roughly speaking) and foundational
approaches to physics, the latter applying to proper
theories (the definition of this unfortunately relying on very few previously known examples, such as GR). Anyway, hopefully the amount of discussion sets the tone for a pleasant week.
The weather, on the other hand, does not look like improving.
