The Road to Hell

The Most Powerful Dice - Numberphile
This guy has a very subtle style. He leads you down the primrose path, one logical step after another until you get to a conundrum.

I'm reading The Gone Away War by Nick Harkaway (who it turns out is John LeCarre's son) and a lot of what goes on in this book follows the same sort of inescapable logic. This leads to that which leads to this other which leads to war, murder, death and destruction.

Be careful with your logic. It can lead you to places you don't want to go. When that happens, you might want to go back and check your assumptions. It's a pretty safe bet that at least one of them is confusing fact with reality.
