Terry Rudolph: Quantum theory: it’s unreal
Understanding physics is usually about telling stories of how and why stuff happens, and quantifying and confirming these tales with a mix of mathematics and observation. The case of quantum theory is anomalous because although we have the mathematics and observations, scientists struggle to find a ‘sensible’ underpinning narrative.
