Sonic Weapons

Those of us with a maritime bent know about modern sonic cannons used to defend commercial shipping interests from pirates. Now comes an article about turning sound to medical use or to far more devastating military purposes. The technology exists and is being developed by scientists at the California Institute of Technology. The scientists developed a way to focus sound waves in one specific location while amplifying those waves. Taken to extremes, you melt large metallic objects (and the lifeforms therein). Applied with skill and finesse, you destroy disease processes in the body without damaging surrounding tissues. Does that expose one of the great truisms of humanity? It's not the size of the explosion - it's how you use it?
