Jordi Savall has made a career of reviving ancient music. Whatever the age of the songs, though, he doesn't play them as museum-piece recreations, preserved in isolation. Savall takes great pleasure in smashing together music from different times and different cultures.
Here's a stumper: How many parts can you divide a line into?
It seems like a simple question. You can cut it in half. Then you can cut those lines in half, then cut those lines in half again. Just how many parts can you make? A hundred? A billion? Why not more?
You can keep on dividing forever, so every line has an infinite amount of parts. But how long are those parts? If they're anything greater than zero, then the line would seem to be infinitely long. And if they're zero, well, then no matter how many parts there are, the length of the line would still be zero.
In the middle of the Mojave Desert, between Los Angeles and Las Vegas, there is a place that looks just like Afghanistan.
There are villages with houses, shops, a mosque and a marketplace. But it is all a facade. The area is actually a U.S. Army installation, the Fort Irwin National Training Center. If you want to see how a decade of fighting has profoundly changed the way the U.S. prepares its soldiers for war, this is where you come.
