Strontium atomic clock demonstrates super-fine 'ticks'

Strontium atomic clock demonstrates super-fine 'ticks' from PhysOrg.com

Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock—techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum computers using neutral atoms as bits of information.

New sequential decision making model could be key to artificial intelligence

New sequential decision making model could be key to artificial intelligence from PhysOrg.com

“Decision making,” Mikhail Rabinovich tells PhysOrg.com, “is everywhere, and not just with humans. Animals use it, and robots do. But the traditional approach to decision making is too simple.”
