Einstein's 'Spooky Physics' Gets More Entangled - Yahoo! News

  • idea riled Einstein so much he called it "spooky
    action at a distance    ."




    A new study found that this eerie
    quantum link     can apply even to situations that resemble the larger,
    everyday world. Scientists entangled two pairs of vibrating particles separated
    in space, so that when one pair was forced to change its movement, the other
    pair did as well.

  • Previous experiments have entangled the internal properties
    of particles, such as spin states, but this is the first time scientists have
    entangled the particles' pattern of motion.




    The breakthrough could help researchers build quantum
    computers    , which could theoretically make calculations much faster than
    existing technology.

In Defense of Distraction

  • Over the last twenty years, Meyer and a host of other researchers have proved again and again that multitasking, at least as our culture has come to know and love and institutionalize it, is a myth. When you think you’re doing two things at once, you’re almost always just switching rapidly between them, leaking a little mental efficiency with every switch. Meyer says that this is because, to put it simply, the brain processes different kinds of information on a variety of separate “channels”—a language channel, a visual channel, an auditory channel, and so on—each of which can process only one stream of information at a time. If you overburden a channel, the brain becomes inefficient and mistake-prone.
  • The only time multitasking does work efficiently, Meyer says, is when multiple simple tasks operate on entirely separate channels—for example, folding laundry (a visual-manual task) while listening to a stock report (a verbal task).

Beware the Twitter Flitterers - eMarketer

  • According to comScore Media Metrix 18-to-24-year-olds, the traditional social media early adopters, are not driving Twitter growth—25-to-54-year-olds are.

Chicago Reader | The Green Issue | Where Alternative Energy Meets Alt-Country: Ryan Boyles can record your band or make your electric meter run backward. By Ed. M. Koziarski

  • Later that year Boyles incorporated Windy City Solar, which he runs out of a one-room office in a Humboldt Park two-flat, upstairs from the recording studio he shares with the landlord. He’s since phased out the carpentry work to focus on solar electric.


    Last spring the Illinois legislature sowed the seeds for a solar boom in Chicago by passing a “net-metering” law, under which people with solar arrays with capacities up to 40 kilowatts are credited at retail rate for any electricity they feed back into the grid up to the value of their electric bill—ComEd spokeswoman Rachel Gerds compares it to rollover minutes.
