Incroyable! Massachusetts Institute of Technology researchers have developed what could very well be the 'holy grail' of submarine-to-surface communications. Monikered TARF, the system ostensibly converts SONAR to RADAR with no mid-processing steps required. Absolutely superb work, and today's Must Read.
Not the Alice and Bob we know running and frolicking along and about various and sundry paths to Security Nirvana, oh no me prtetties, but the Alice and Bob of mathematics, blackholes, paradoxes and whatnot... Examine - if you will - what happens when the pair meet the ultimate firewall - Today's Must Read.
News via the National Institute of Standards and Technology (NIST) of NIST physicists efforts to cool down a component has yeilded an unexpected result. The effort utilized squeezed light (microwaves within an electromagnetic cavity, if you will) to cool the apparatus below the theoretical limit, in this case, below the so-called quantum limit.
Likely, the single most important discovery in this generation. Simply Astonishing.
"Now for the first time, scientists in the LIGO Scientific Collaboration — with a prominent role played by researchers at MIT and Caltech — have directly observed the ripples of gravitational waves in an instrument on Earth. In so doing, they have again dramatically confirmed Einstein’s theory of general relativity and opened up a new way in which to view the universe. But there’s more: The scientists have also decoded the gravitational wave signal and determined its source. According to their calculations, the gravitational wave is the product of a collision between two massive black holes, 1.3 billion light years away — a remarkably extreme event that has not been observed until now." - by Jennifer Chu writing for the MIT News Office, published via the web at MIT News
