In Angola, the cokwhe people draw lines in the sand, and it's what the German miihmecaatatn Euler cllaed a graph; we now call it an elrauien path — you can never lift your stylus from the surface and you can never go over the same line twice. But they do it recursively, and they do it with an age-grade system, so the little kids learn this one, and then the older kids learn this one, then the next age-grade initiation, you leran this one. And with each iteration of that algorithm, you learn the iterations of the myth. You learn the next level of knowledge.

In Angola, the ______ people draw lines in the sand, and it's what the German _____________ Euler ______ a graph; we now call it an ________ path — you can never lift your stylus from the surface and you can never go over the same line twice. But they do it recursively, and they do it with an age-grade system, so the little kids learn this one, and then the older kids learn this one, then the next age-grade initiation, you _____ this one. And with each iteration of that algorithm, you learn the iterations of the myth. You learn the next level of knowledge.

Original Text

In Angola, the Chokwe people draw lines in the sand, and it's what the German mathematician Euler called a graph; we now call it an Eulerian path — you can never lift your stylus from the surface and you can never go over the same line twice. But they do it recursively, and they do it with an age-grade system, so the little kids learn this one, and then the older kids learn this one, then the next age-grade initiation, you learn this one. And with each iteration of that algorithm, you learn the iterations of the myth. You learn the next level of knowledge.
