Submission + - The Earth is a gravitational wave detector (aps.org)

b30w0lf writes: Gravitational wave detection—i.e. the detection of propagating ripples in spacetime—is a hot subject these days with ground-based interferometer experiments like LIGO active, and hopes for a space interferometer like LISA. But, physicist Freeman Dyson proposed back in 1969 that the earth itself could be used as a gravitational wave detector. The idea is behind the approach is that gravitational waves impact the earth’s crust, causing potentially detectable seismic waves. Using Dyson’s approach, Physicists at Harvard and NINP, Florence were able to put an upper limit on the intensity of gravitational background radiation based on a year of observational seismic data. The upper limit they found improved currently laboratory upper limits by 9 orders of magnitude.

Comment Re:Why can't I turn off the ads? Otherwise...OK (Score 1) 384

Normal Slashdot has a "disable ads" button if you have good karma. I believe that is what they are rederring to.

Indeed. That's Maker mode, as I mentioned, though Maker mode doesn't get offered for merely good karma.

I've implemented ad hiding for Maker mode, but if I can reproduce a bug with it, I'll fix it.

Comment Makes sense, but then what wouldn't? (Score 2) 114

The acquisition makes sense, in that they obviously want ratings of restaurants (and other places) on Maps, and they've already changed tactics there once or twice. This'll pretty much take care of that problem.

I start to wonder, though, whether any acquisition by Google wouldn't "make sense". Their purchase of Motorola Mobility makes sense, too (though not to everyone). When you buy a consumer electronics company and a restaurant guide in consecutive months, what won't you buy? What acquisitions won't "make sense"?

Google buys Pacific Gas and Electric for $20B. Makes sense...

Submission + - Wicked Lasers Sells One-Watt Green Laser (wickedlasers.com)

cogent writes: "Wicked Lasers, famous for last year's 1000mW handheld blue laser, and infamous for its handling of six-month-long backorders, is now selling a green version. There are three power levels, each priced at $1/mW. Since the eye is far more sensitive to green than to blue, this is pretty much the state of the art in putting-dots-on-stuff technology. Wicked Lasers sent out an email, promising to handle backorders much better this time."
