Actually mirrors have been around since the Middle ages, but they were made of polished metal. Glass backed with a metallic coating replaced the older versions in 13th century Europe and quickly became a must have for the wealthy. Actually, mirrors made in Venice are well known for their workmanship and would be worth a small fortune now, so keep your eyes open when visiting antique shops. You just never know what you might find.
Existing communications and computer architecture are increasingly being limited by the pedestrian speed of electrons moving through wires, and the future of high-speed communication and computing is in optics, experts say. The Holy Grail of results would be "wireless interconnecting," which operates at speeds 100 to 1,000 times faster than current technology. The new discovery, made by researchers at Oregon State University, the University of Iowa and Philipps University in Germany, has identified a way in which nanoscale devices based on gallium arsenide can respond to strong terahertz pulses for an extremely short period, controlling the electrical signal in a semiconductor. The research builds on previous findings for which OSU holds an issued patent.
