Zak and Derek discuss the "controversial" value of Newton's gravitational constant G. They cover the history of its measurement and how the value (and confidence in that value) has changed over time.

Zak and Derek discuss the big question: why is the future different than the past? Why do we remember the past but not the future?


Much the discussion comes from Sean Carroll’s book, “From Eternity to Here: The Quest for the Ultimate Theory of Time

Zak and Derek discuss nothing less than the fundamental nature of reality. They start with the arguments made in the Einstein, Podolsky, and Rosen paper from 1935, which were then tackled by John Bell in 1964 with Bell’s Theorem and Bell inequalities.
