Participates in the first Solvay Conference, discussing radiation and quantum theory with leading physicists.
Challenges Niels Bohr with thought experiments testing the completeness of quantum mechanics.
Participates in the fifth Solvay Conference and debates the interpretation of quantum mechanics.
Einstein argued that measuring the mass loss of a timed photon box could in principle determine both the photon's energy and its emission time more precisely than quantum uncertainty allowed.
At the Solvay Conference Einstein proposed a box-and-clock thought experiment intended to challenge the energy-time uncertainty relation by weighing a box before and after a photon escaped.
Attends the sixth Solvay Conference and continues discussions on quantum theory and field physics.
