| Category: Science It must be taking a while to nail this technology down... from 9 years ago... Imagine this: Your next stereo system arrives without big, boxy loudspeakers. Instead, it has a pair of silvery disks, each the size of an Oreo cookie and covered with a dozen or so circular crystals. These curious structures, which are similar to the piezoelectric quartz crystals that keep time in watches, will tease musical notes out of thin air--and the sound will be better than that of speakers costing thousands of dollars. |
