• "A Mock Debate on Time with JULIAN BARBOUR AND TIM MAUDLIN": Julian Barbour and Tim Maudlin argue their opposite position on whether time is a fundamental reality or an illusion shaped by human perception and experience.
• Timeless Explanation: A New Kind of Causality, Julian Barbour: There are serious indications from attempts to create a quantum theory of gravity that time must disappear completely from the description of the quantum universe. This has been known since 1967, when DeWitt discovered the Wheeler-DeWitt equation. I shall argue that this forces us to conceive explanation and causality in an entirely new way.
