Wearable devices that track our health may do more harm than good

Fear of mortality might underlie physicists’ fondness for the anthropic principle, multiverses, superdeterminism and other shaky ideas

Quantum mechanics inspires us to speculate that interactions between entities, not entities in themselves, are fundamental to reality

Ordinary human dilemmas are tougher to solve than the most difficult problems of physics and mathematics

Theories that try to explain these big metaphysical mysteries fall short, making agnosticism the only sensible stance

A 92-year-old essay provokes musings on the nature of knowledge, reality—and uptalk

Can we ever really know the world?
