Physics World is celebrating the 2025 International Year of Quantum Science and Technology (IYQ), which aims to raise global awareness of quantum physics and its applications. Stayed tuned to Physics World and our international partners throughout the year for our coverage of the IYQ. You can also see how IOP Publishing's quantum-related journals are marking the year through ongoing activities.
Philip Ball looks at how a little-known paper by Niels Bohr demonstrates the turmoil in physics on the brink of quantum mechanics
