Quarks Know Their Left From Their Right 150

sciencehabit writes "How an electron interacts with other matter depends on which way it's spinning as it zips along—to the right like a football thrown by a right-handed quarterback or the left like a pigskin thrown by a lefty. Now, physicists have confirmed that quarks—the particles that join in trios to form the protons and neutrons in atomic nuclei—exhibit the same asymmetry. The result could give physics a new weapon in the grand hunt for new particles and forces. Or they can search for subtle hints of exotic new things beyond their tried-and-true standard model by studying familiar particles in great detail. In the latter approach, the new experiment gives physicists a way to probe for certain kinds of new forces."

    Back to the article... Parity violation has been known in quarks for many many years - see http://en.wikipedia.org/wiki/K... [wikipedia.org] (hint: CP violation means charge-parity violation, which is a special case of Parity violation)

    How ironic that the quote at the bottom of Slashdot says now

    Build a system that even a fool can use and only a fool will want to use it.

    We've deleted nothing, as the vast sea of comments complaining about the beta in every story should attest to. All submissions are still around, too, though they eventually drop out of the firehose like any other submission does. If you want a simple test, bookmark the URL whenever you submit something.

    I suppose it wouldn't be a redesign without conspiracy theories, though.

    Given the way you guys are going back to yesterday's threads and downmodding all the posts about Beta wholesale after you know that other mods won't see them to push them back up again, you will forgive me for not giving your voice credibility.

    Fortunately, you don't have to rely on credibility. Here's a story more than a day old [slashdot.org]. About 15% of the comments are rated 4 or 5, which is a pretty typical percentage, and all of them are complaining about the beta. It's like that in a lot of stories. As for submissions -- well, they pass through the firehose like everything else, and why you don't ever see submissions from a week ago sticking around in it. That's why it's called the firehose.

If you are smart enough to know that you're not smart enough to be an Engineer, then you're in Business.
