First blue sky thinking workshop: The arrow of time

Join us online for the first of three annual one-day workshops in which we will bring together a network of scientists and philosophers from around the world working on foundational problems relating to the arrow of time in theoretical physics (with a focus in particular on quantum mechanics and the nature of entanglement and decoherence in open quantum systems and the quantum-classical transition), philosophy and biology.

The talks are meant to be deliberately speculative and focus on current problems and open issues in the field. This workshop will be held online and will encourage debate amongst delegates.
