Smaller is stronger -- now scientists know why
As structures made of metal get smaller -- as their dimensions approach the micrometer scale (millionths of a meter) or less -- they get stronger. Scientists discovered this phenomenon 50 years ago while measuring the strength of tin "whiskers" a few micrometers in diameter and a few millimeters in length.
