Why these picks
Sometimes you have to listen to a material to really know what is going on inside. Whether it is a piece of ancient stone or a rusted bridge, the eyes don't always tell the whole story. This week, we found a few stories that show how people are using sound and math to peek into places we usually can't reach.
