You are invited to join us all in solving a mystery. A man named Dow signed up for a mysterious clinical trial called The Abacus Project.  It uses advanced technology to explore the very nature of reality. Dow has written 18 letters describing his experience with this project. This is letter 6. Joining the Letter 6 mystery sleuthing team this week are the insights of physicist David Tong, anthropologist Victor Turner and cognitive psychologist Merlin Donald.  Kind of.  In a learning out loud AI Puppet Show kind of way. Let's play.
