Philosopher's Zone About time, part 1: Newton's exploding clock
Sep 5, 2021
Join Newton, a renowned scientist and philosopher, as he discusses the weird tricks of time. From twins growing older at different rates to broken vases reassembling themselves, explore the multifaceted nature of time in physics. Discover the connection between Newton's laws and the second law of thermodynamics, and delve into the twin paradox and time dilation. Lastly, explore quantum gravity and the potential disappearance of time at a fundamental level.

Episode notes
Newton's Universal Clock
- Newtonian physics assumes a single universal clock governing all bodies.
- Craig Callender says this underpins objective duration and time measurements.
Broken Vases And Time Symmetry
- Craig Callender describes a China-shop example where vases shatter but never reassemble.
- He uses it to show Newtonian laws allow time-reversed processes we do not observe.
Entropy Picks A Direction
- The second law ties time's direction to entropy increases and probability.
- Craig Callender explains systems move toward vastly more probable configurations over time.
