Science is a perpetual search for new ideas, but this says nothing of how correct it is. Professor Angell argues that no matter how elaborate, sophisticated or subtle a scientific description may appear, it always generates paradox. Science, the formal enterprise for probing the nature of reality, is awash with such paradoxes, from zero and infinity, to causality, particles and gravity. Reality emerges from our systems of observation, but Ian argues that paradox is a fundamental property of observation within emergent systems.
