Device collects ambient electromagnetic energy from radio/tv waves
Tentzeris and his team are using inkjet printers to combine sensors, antennas and energy scavenging capabilities on paper or flexible polymers. The resulting self powered wireless sensors could be used for chemical, biological, heat and stress sensing for defense and industry; radio frequency identification (RFID) tagging for manufacturing and shipping, and monitoring tasks in many fields including communications and power usage.Caste-away
Mr. Jha said he wanted to point out inconsistencies even in the attitudes of people who might think of themselves as having moved beyond the issue of caste.

A Brief History of Mapmaking
Pei Xiu (224–271), known as the “Ptolemy of China,” produced maps with a geometrical grid and graduated scale to more accurately determine location and the distance between points. In the 12th century, during the Song Dynasty, detailed maps of China and the surrounding region were etched into stone.
