The main challenge that television presents is that I have a tendency to say things with a great deal of precision and accuracy. Often a description of that sort, which will work in a book because people can read it slowly - they can turn the pages back and so on - doesn't really work on TV because it interrupts the flow of the moving image.

Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.

Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.
