Some time ago, I posted a fractions puzzle involving flat bread. You can read about it here. Here’s the question – if I take a flat piece of bread, and give you half, then you give me back a quarter, then I give you back an eighth, and you give me back 1/16, and so on ad infinitum, how much of the original flat bread do I have?

I recently uploaded a game I call “Dinosaur Dodger“. It’s based on an interesting paradox I read about on this blog, by an economist who has authored a number of good books. The paradox is called the “Paradox of the Absent Minded Driver”. It goes like this : imagine a driver, driving home along a highway. They need to take the second exit to get off, but for some reason they can’t recall which exit they are at when they get to an exit.
