The Alps are growing just as quickly in height as they are shrinking. This paradoxical result comes from a new study by a group of German and Swiss geoscientists. Due to glaciers and rivers, about exactly the same amount of material is eroded from the slopes of the Alps as is regenerated from the deep Earth’s crust.
To counteract these problems, inventors experimented with solid-body guitars. In 1940, Les Paul created “The Log,” a guitar whose strings and pickups were mounted on a guitar body carved from a solid block of wood. The first recordings of electric guitars were made in 1933 by Hawaiian music artists such as Andy Iona.
