Submission + - China Start Development of Hybrid Spaceplane (popsci.com)

hackingbear writes: While SpaceX is making news with its recoverable rockets, China announced that it is working on the next big thing in spaceflight: a hypersonic spaceplane. The China Aerospace Science and Technology Corporation is beginning advanced research on a high tech, more efficient successor to the retired Space Shuttle, with hybrid combined cycle engines combining turbofan, ramjet, scramjet and rocket engines, that can takeoff from an airport's landing strip and fly straight into orbit. CASTC's rapid research timeline also suggests that the reports in 2015 of a Mach 4 test flight for a recoverable drone testbed for a combined cycle ramjet/turbofan engine were accurate. And China also has the world's largest hypersonic wind tunnel, the Mach 9 JF-12, which could be used to easily test hypersonic scramjets without costly and potentially dangerous flight testing at altitude. Its nearest competitor, the British Skylon in contrast uses pre-cooled jet engines built by Reaction Engines Limited to achieve hypersonic atmospheric flight, as opposed to scramjets. Both spacecraft will probably first fly around the mid 2020s.

Submission + - Astronomers to Announce "Earth-Like" Planet at Proxima Centauri (seeker.com)

astroengine writes: Scientists are preparing to unveil a new planet in our galactic neighborhood which is "believed to be Earth-like" and orbits its star at a distance that could favor life, German weekly Der Spiegel reported Friday. The exoplanet orbits a well-investigated star called Proxima Centauri, part of the Alpha Centauri star system, the magazine said, quoting anonymous sources. "The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could allow it to have liquid water on its surface — an important requirement for the emergence of life," said the magazine. Though we need to be cautious of any report before an official announcement, this could be very exciting news as Proxima is, theoretically, within reach of an interstellar probe.

"The problem is, how do we fix it? Having many friends and family members who are teachers, I can also 100% say that education classes don't confer any particular ability to teach either."

Yup I agree. I hesitate to say that teacher training is the only or even best solution (having a BEd myself) but I think it's probably a good place to start.

How dare students expect to be properly taught by people they are paying to teach them?

You didn't actually challenge my assertion that a PhD doesn't confer an ability to teach, rather you merely acknowledged that the teachers suck and then claim that students are entitled for expecting to get any kind of value out of their expensive tuition dollars. If in your world the only thing a degree confers is an ability to acquire knowledge independently, then all a university is is a massively overpriced testing facility.

Probably has more to do with the fact that these professors have little to no teacher training. There is an implicit assumption that a PhD in mathematics automatically confers an ability to teach.

It makes no sense...a PhD in chemistry doesn't confer you an ability to research astronomy...why should it make you a good teacher?

I'd say it's more like teaching people how to resist torture, seen as that is a sanctioned US security technique.

Further, the idea that drug lords can infiltrate federal agencies in the absence of polygraph tests is really scary. That is essentially their point. That means all their investigative powers are useless, and it all boils down to a pseudoscience test.

Not to mention, we don't seem to have any problem shedding the taboos against torture and killing first responders (Guantanamo and US drone double tap strikes).

Both are war crimes and both are carried out knowingly and intentionally. At this point it would make more sense for Russia to be the human rights watch dog of the world.

"It aims to produce intelligent robo-sentinels that can patrol areas, and learn to detect abnormalities in human behavior."

Forget "abnormalities," if they just programmed the robots to detect and harass black people, you could replace the entire NYPD!
