Researchers Build a Cellphone that Sees through Walls
What's the Latest Development?
By combining advances in the fields of electromagnetism and computing, researchers at UT Dallas have created a cellphone that can see through walls, aiding humans in all sorts of real-life situations. Scientists have opened up a previously unusable portion of the electromagnetic spectrum called the terahertz range while further developing an inexpensive method of making computer chips using Complementary Metal-Oxide Semiconductor (CMOS) technology which "forms the basis of many consumer electronic devices used in daily life such as personal computers, smart phones, high definition TV and game consoles."
What's the Big Idea?
Dr. Kenneth O, leader of the new research and professor of electrical engineering at UT Dallas is optimistic about the technology: "The combination of CMOS and terahertz means you could put this chip and receiver on the back of a cellphone, turning it into a device carried in your pocket that can see through objects," he said. "Consumer applications of such technology could range from finding studs in walls to authentication of important documents. Businesses could use it to detect counterfeit money. Manufacturing companies could apply it to process control..."

Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
At least he wasn't burned at the stake, right?
- The letter suggests Galileo censored himself a bit in order to fly more under the radar. It didn't work, though.
- The Royal Society Journal will publish the variants of the letters shortly, and scholars will begin to analyze the results.
- The letter was in obscurity for hundreds of years in Royal Society Library in London.
