What about the part that the wave is reflected back to the otherside of the cavity? Does it not just - reflect back and forth technically creating a net thrust of zero? I thought that guy claimed the slots inside the drive were the key to it's operation, yet the null device - one which did not contain the slots - worked the same.

Here's my past experience with microwave experiments: the damn things interferes with all your instruments in the most absurd of ways.

Don't believe me? Go take any normal voltmeter, remove the probe leads, and run the microwave with the door open (by passing the interlock of course) for just 5 seconds within a few feet of it - you'll get voltage reading. If you're not getting a reading then you are probably using a well shielded device - likely a Fluke or Keithley meter. Even those meters will likely show something still, I'd be impressed if they didn't.

So them measuring something like a few milliNewtons on a device that probably measures small signals and using even 50W in an enclosed cavity nearby - which itself will reemit some radio waves - on a metal table or in a steel vacuum chamber, where their own simulations show a large magnetic field gradient from one end of the device to the other - is enough evidence for me at least to show they're fooling themselves.

This is the result of getting jerked around by politicians every few years. America got to the moon because it was something everyone could agree upon that would stick it to the Ruskies!

After doing the bulk r&d for the Apollo project, the budget sort of tapered off ... https://upload.wikimedia.org/w...

It's like every President since Kennedy felt they needed to give NASA some long term objective just to have the following Presidency give them something else, and have both House and Senate subcommittees give their two cents on objectives and funding.

It's just a recipe for the bullshit you see right now.

NASA needs to study the multivariable behaviour of Earth's climate to better understand the climate of other planets. It's cheap and easy, and provides lots of science relative to larger space exploration missions with limited capability. How the fuck can we make claims about a far off planet's atmosphere from light spectrum observations alone if we can't come to a consensus on our own planet's atmosphere?

You have to give the guy some slack. He's lived longer than my grandfather yet was diagnosed with a disease that should have killed him in a couple of years. Of course he'll have something negative to say about aggression - what the fuck is he going to do about someone being violent to him and his family? Ram them with his electric wheel chair while making snarky comments via text-to-voice?

Considering this audience is pretty much the only one that understands the implications behind these revelations. WE should be the ones raising the issues and getting in the government's face about this, but technologists are notoriously passive when it comes to protesting the government. With that in mind, there's not too much _I_ can do as a Canadian to protest the NSA/GCHQ, but there's definitely the CSE who are one of the "5 eyes" members.

However the easiest response to mass surveillance is mass encryption, and that doesn't involve standing outside for hours shouting at people who couldn't care less or trying to educate the average person about why this isn't just part of the fight on 'terrorism' but it's a direct assault on all of us. Obviously the entire cell phone network design will need an overhaul after these keys have been leaked, and hopefully the overhaul uses better techniques.

Mark Zuckerberg Throws Pal Joe Green Under the Tech Immigration Bus 261

theodp (442580) writes "A month after he argued that Executive Action by President Obama on tech immigration was needed lest his billionaire bosses at Mark Zuckerberg's FWD.us PAC have to hire 'just sort of OK' U.S. workers, Re/code reports that Joe Green — Zuckerberg's close friend and college roommate — has been pushed out of his role as President of FWD.us for failing to Git-R-Done on an issue critical to the tech community. "Today, we wanted to share an important change with you," begins 'Leadership Change', the announcement from the FWD.us Board that Todd Schulte is the new Green. So what sold FWD.us on Schulte? "His [Schulte's] prior experience as Chief-of-Staff at Priorities USA, the Super PAC supporting President Obama's re-election," assured Zuckerberg in a letter to FWD.us contributors, "will ensure FWD.us continues its momentum for reform." Facebook, reported the Washington Post in 2013, became legally "dependent" on H-1B visas and subject to stricter regulations shortly before Zuckerberg launched FWD.us with Green at the helm."

Astronomers Find Star-Within-a-Star, 40 Years After First Theorized 72

Posted by Soulskill

derekmead writes: After 40 years, astronomers have likely found a rather strange celestial body known as a Thorne–Zytkow object (TZO), in which a neutron star is absorbed by a red supergiant. Originally predicted in the 1970s, the first non-theoretical TZO was found earlier this year, based on calculations presented in a paper forthcoming in MNRAS.

TZOs were predicted by astronomer Kip Thorne and Anna Zytkow, who wasthen postdoctoral fellow at CalTech. The pair imagined what might happen if a neutron star in a binary system merged with its partner red supergiant. This wouldn't be like two average stars merging. Neutron stars are the ancient remnants of stars that grew too big and exploded. Their cores remain small — about 12.5 miles across — as they shed material out into space. Red supergiants are the largest stars in the galaxy, with radii up to 800 times that of our sun, but they aren't dense.

Enthusiast Opts For $2200 Laser Eye Surgery To Enhance Oculus Rift Experience 109

Posted by timothy

An anonymous reader writes After 30 years of wearing glasses, one man says that the Oculus Rift virtual reality headset has prompted him to get laser eye surgery. With farsightedness and astigmatism, he says, "Never thought much about the laser surgery until the Rift, that's for sure." He has an appointment to get the $2200 surgery on the 13th of this month. "For me it is clear, my eyeglasses are like an obstacle for optimal VR experience," he said. He hopes the surgery will remove his need for glasses, which can be uncomfortable inside of the Rift, if they fit at all, and cause several issues such as scratched lenses and lower field of view. Oculus plans to make the consumer version of the Oculus Rift (aka CV1) more friendly to glasses wearers, "...we have a lot of great ideas for supporting glasses in the consumer version [of the Rift] (especially since a huge portion of the Oculus team wears glasses everyday!)" they noted in their Kickstarter.

Only through hard work and perseverance can one truly suffer.
