Simon Conway Morris: I'd be very happy if Zurich shares a Nobel Prize at some point for improving our understanding of how the classical world emerges from quantum mechanics. Kieffek says, if sending particles through a Stern-Gurlock device measures their spin, how does one go about aligning the spin of two particles without measuring them? Or is this just a non-practical idea that only gets proposed in thought experiments? Simon Conway Morris: The proof of the pudding is in the tasting. We'll see which set of ideas and concepts is actually most useful moving forward.
