Celebrating Genocide – The Real Story of Thanksgiving

Irwin Ozborne, ContributorThanksgiving: Celebrating all that we have, and the genocide it took to get it.Thanksgiving is one of the most paradoxical times of the year. We gather together with friends and family in celebration of all that we are thankful for and express our gratitude, at the same time we are encouraged to eat in excess. But the irony really starts the next day on Black Friday. On Thursday we appreciate all the simple things in life, such as having a meal, a roof over [...]

This revolutionary discovery could help scientists see black holes for the first time


supermassive black hole
Artist's concept of the black hole.



Excerpt from finance.yahoo.com
Of all the bizarre quirks of nature, supermassive black holes are some of the most mysterious because they're completely invisible.
But that could soon change.
Black holes are deep wells in the fabric of space-time that eternally trap anything that dares too close, and supermassive black holes have the deepest wells of all. These hollows are generated by extremely dense objects thousands to billions of times more massive than our sun.
Not even light can escape black holes, which means they're invisible to any of the instruments astrophysicists currently use. Although they don't emit light, black holes will, under the right conditions, emit large amounts of gravitational waves — ripples in spacetime that propagate through the universe like ripples across a pond's surface.
And although no one has ever detected a gravitational wave, there are a handful of instruments around the world waiting to catch one.

Game-changing gravitational waves

This illustration shows two spiral galaxies - each with supermassive black holes at their center - as they are about to collide. 

Albert Einstein first predicted the existence of gravitational waves in 1916. According to his theory of general relativity, black holes will emit these waves when they accelerate to high speeds, which happens when two black holes encounter one another in the universe.  

As two galaxies collide, for example, the supermassive black holes at their centers will also collide. But first, they enter into a deadly cosmic dance where the smaller black hole spirals into the larger black hole, moving increasingly faster as it inches toward it's inevitable doom. As it accelerates, it emits gravitational waves.
Astrophysicists are out to observe these waves generated by two merging black holes with instruments like the Laser Interferometer Gravitational-Wave Observatory.
"The detection of gravitational waves would be a game changer for astronomers in the field," Clifford Will, a distinguished profess of physics at the University of Florida who studied under famed astrophysicist Kip Thorne told Business Insider. "We would be able to test aspects of general relativity that have not been tested."
Because these waves have never been detected, astrophysicists are still trying to figure out how to find them. To do this, they build computer simulations to predict what kinds of gravitational waves a black hole merger will produce. 

Learn by listening

In the simulation below, made by Steve Drasco at California Polytechnic State University (also known as Cal Poly), a black hole gets consumed by a supermassive black hole about 30,000 times as heavy.
You'll want to turn up the volume.
What you're seeing and hearing are two different things.
The black lines you're seeing are the orbits of the tiny black hole traced out as it falls into the supermassive black hole. What you're hearing are gravitational waves.
"The motion makes gravitational waves, and you are hearing the waves," Drasco wrote in a blog post describing his work.
Of course, there is no real sound in space, so if you somehow managed to encounter this rare cataclysmic event, you would not likely hear anything. However, what Drasco has done will help astrophysicists track down these illusive waves.

Just a little fine tuning 

Gravitational waves are similar to radio waves in that both have specific frequencies. On the radio, for example, the number corresponding to the station you're listening to represents the frequency at which that station transmits.

Right now, astrophysicists only have an idea of what frequencies two merging black holes transmit because they’re rare and hard to find. In fact, the first ever detection of an event of this kind was only announced this month. 

Therefore, astrophysicists are basically toying with their instruments like you sometimes toy with your radio to find the right station, except they don’t know what station will give them the signal they’re looking for.
What Drasco has done in his simulation is estimate the frequency at which an event like this would produce and then see how that frequency changes, so astrophysicists have a better idea of how to fine tune their instruments to search for these waves.
Detecting gravitational waves would revolutionize the field of astronomy because it would give observers an entirely new way to see the universe. Armed with this new tool, they will be able to test general relativity in ways never before made possible.

Concorde Comeback? Two New Jets Plan to Take Air Passengers Supersonic Again




Concorde Comeback? Two New Jets Plan to Take Air Passengers Supersonic Again

Excerpt from yahoo.com

Lockheed Martin and NASA’s N+2 jet could cut cross-country flight times in half. New York to Los Angeles in just over two hours? Passenger jets that fly faster than the speed of sound without that annoying sonic boom?  


That could become reality thanks to two projects that aim to bring supersonic planes back to commercial air travel.  Lockheed Martin is working with NASA on a design called the N+2, an 80-passenger jet capable of cruising at Mach 1.7 (1.7 times the speed of sound). 

But what about that loud sonic boom you get when an airplane exceeds the sound barrier? Lockheed Martin and NASA are working hard to lower the boom, so to speak. They say their proposed new jet will be 100 times quieter than the Concorde, the supersonic passenger jets that flew transatlantic routes from 1969 until they were grounded in 2003.

A quieter jet would allow the N+2 to fly at supersonic speeds on cross-country routes as the FAA, concerned about sonic booms going off over sleepy U.S. suburbs, currently bans civilian planes from going all “Danger Zone” in American airspace. Lockheed Martin says their new jet would cut cross-country flight times in half.  Related: Race for the First Windowless Plane Heats Up  A rival supersonic jet development project is underway in Reno, Nevada, where European aircraft maker Airbus is working with American firm Aerion on a new, fuel-efficient plane for business clients. The 12-passenger Aerion AS2 will fly at 1,217 mph (which is almost as fast as the Concorde, which flew at 1,350 mph). That would take you from New York to London in three hours and from Los Angeles to Tokyo in six.  

Since the AS2 would do most of its flying over oceans, its designers aren’t as concerned with loud sonic booms. The AS2’s big innovation is fuel efficiency, with new wings that are said to reduce drag by 20 percent.  The makers of the AS2 plan to deliver their first plane in 2022 while Lockheed Martin hopes to have the N+2 flying in 2025.

7-Week-Old Baby Says ‘Hello’ ~ Mom: ‘I’m Glad I Got It on Video’



Mom of 7-Week-Old Baby Who Says ‘Hello’ tells Yahoo Parenting: ‘I’m Glad I Got It on Video’
Toni McCann & newborn Cillian

Excerpt from yahoo.com

 Like mother, like son. Toni McCann says her newborn, Cillian, already has her gift of gab and says “hello” — at just seven weeks old. The Belfast, Northern Ireland youth drama-school teacher, 36, caught one of his amazing utterances on video and posted it to YouTube, where the footage has gone viral, raking in more than 366,000 views since March 3.  







“I am a huge talker,” McCann tells Yahoo Parenting. “Cillian had been trying to communicate for a while, but it really surprised me how clear his ‘Hello’ was. I’m glad I got it on video, as I’m sure no one would have believed me.”

The mother of four – including Sophia, 12; Ellie, 11; and Eva, 8 — with her husband Paul McCann recently told one of her daughter’s music teachers that the girls’ little brother had said “Hello.” But, the mom admits, “He just looked at me like I was nuts.” 

Ditto regarding a few viewers of the clip. “Some people don’t believe it’s real, that it’s been edited, but on the whole most people love it,” McCann tells The Daily Mail. “That is really lovely for me as there is so much bad in the world it’s great that my wee son is spreading some joy.” 

But the tot’s biggest fans are right at home. His sisters are so excited about the pseudo talking that they’ve been trying to get Cillian to keep practicing. “After he said hello to me, my youngest daughter tried and he said a much quicker ‘hawo,’” McCann tells Yahoo Parenting. “It was cute but not as clear as the first one.”

Still, the mom believes her boy’s greeting wasn’t just luck. “He was trying to speak for a while, but that day I knew he was trying to say something,” she tells the Mail. “I’d read that babies communicate from a young age and to give them space to answer when you talk to them.” McCann says she was mindful, then, of giving her son a moment, as opposed to how she’d communicated with her girls: “I think I probably just talked ‘at’ them and didn’t give them space to respond.”

Google Chairman Eric Schmidt: "The Internet Will Disappear"


 


Excerpt from hollywoodreporter.com

Google executive chairman Eric Schmidt on Thursday predicted the end of the Internet as we know it.

At the end of a panel at the World Economic Forum in Davos, Switzerland, where his comments were webcast, he was asked for his prediction on the future of the web. “I will answer very simply that the Internet will disappear,” Schmidt said.

“There will be so many IP addresses…so many devices, sensors, things that you are wearing, things that you are interacting with that you won’t even sense it,” he explained. “It will be part of your presence all the time. Imagine you walk into a room, and the room is dynamic. And with your permission and all of that, you are interacting with the things going on in the room.”

Concluded Schmidt: “A highly personalized, highly interactive and very, very interesting world emerges.”

The panel, entitled The Future of the Digital Economy, also featured Facebook COO Sheryl Sandberg and others.
Earlier in the debate, Schmidt discussed the issue of market dominance. The European Union has been looking at Google’s search market dominance in a long-running antitrust case, and the European parliament late last year even called for a breakup.
“You now see so many strong tech platforms coming, and you are seeing a reordering and a future reordering of dominance or leaders or whatever term you want to use because of the rise of the apps on the smartphone,” Schmidt said Thursday. “All bets are off at this point as to what the smartphone app infrastructure is going to look like” as a “whole new set” of players emerges to power smartphones, which are nothing but super-computers, the Google chairman argued. “I view that as a completely open market at this point.”

Asked about his recent trip to North Korea, Schmidt said the country has many Internet connections through data phones, but there is no roaming and web usage is “heavily supervised.” Schmidt said “it’s very much surveillance of use,” which he said was not good for the country and others.

Sandberg and Schmidt lauded the Internet as an important way to give more people in the world a voice. Currently, only 40 percent of people have Internet access, the Facebook COO said, adding that any growth in reach helps extend people’s voice and increase economic opportunity. “I’m a huge optimist,” she said about her outlook for the industry. “Imagine what we can do” once the world gets to 50 percent, 60 percent and more in terms of Internet penetration.
She cited women as being among the beneficiaries, saying the Internet narrows divides.

Schmidt similarly said that broadband can address governance issues, information needs, personal issues, women empowerment needs and education issues. “The Internet is the greatest empowerment of citizens … in many years,” he said. “Suddenly citizens have a voice, they can be heard.”
During another technology panel at the World Economic Forum on Thursday, Yahoo CEO Marissa Mayer, Liberty Global CEO Mike Fries and others answered questions on the need to regulate privacy standards on the Internet and for tech companies following the Snowden case, the Sony hack and the like.


Mayer said that the personalized Internet “is a better Internet,” emphasizing: “We don’t sell your personal data … We don’t transfer your personal data to third parties.” She said users own their data and need to have control, adding that people give up data to the government for tax assessment, social services and other purposes.
Fries said Liberty Global subscribers view billions of hours of content and generate billions of clicks, but added that “today we do nothing.” He explained: “We generate zero revenue from all of that information.” But he acknowledged that big data was big business for a lot of people.

Both executives said transparency was important to make sure users know privacy standards and the like.

Gunther Oettinger, a conservative German politician serving as the European Union’s commissioner for digital economy and society, said on the panel that “we need a convincing global understanding, we need a UN agency for data protection and security.” Asked what form that “understanding” should have, he said he was looking for “clear, pragmatic, market-based regulation.” Explained Oettinger: “It’s a public-private partnership.”

Fries said such a solution was likely not to happen in the near term, given the size of the EU. “I think it is going to take several years,” he said, adding that some countries’ parliaments would likely take a stab at it.

But he warned that a joint solution would make more sense. “We don’t want Germany to have its own Internet,” Fries said. “Some countries may build their own Internets” and “balkanize” the web, he warned.

Mayer said on the issue of regulation: “I like Tim’s idea better of the beneficent marketplace.” She spoke of fellow panelist and computer specialist Tim Berners-Lee, known as the inventor of the World Wide Web.

Asked how Yahoo stores and handles client records, she said the online giant “changed the way we store and communicate data” after Snowden and also changed encryptions between data centers. And the company protects users through encryption methods, she added. Mayer said that trust and confidence of Yahoo users has rebounded since.

Mayer was also asked what happens if a government asks for a user’s data, a question that has new significance after the recent terrorist attacks in Paris, which have led some to call for increased surveillance powers of the Internet for governments. Mayer said Yahoo always assesses if such a request is reasonable. “We have a very good track record for standing up to what’s not reasonable,” she said.

War Is Destroying Syria’s Ancient Treasures, Satellite Photos Show



War Is Destroying Syria's Ancient Treasures, Satellite Photos Show
Satellite images show how much destruction has happened in Syria between December 2011 and July 2014. The Ministry of Justice building (red arrow) is damaged, as is the Khusriwiye Mosque (green arrow).

Excerpt from news.yahoo.com
By Laura Geggel, Staff Writer

Three years of heavy fighting have taken a toll on Syria's archaeological treasures. Five of the country's six World Heritage sites "exhibit significant damage," and some buildings are now "reduced to rubble," according to high-resolution satellite images examined by the nonprofit and nonpartisan American Association for the Advancement of Science (AAAS).

"Only one of Syria's six World Heritage sites — the ancient city of Damascus — appears to remain undamaged in satellite imagery since the onset of civil war in 2011," Susan Wolfinbarger, director of the Geospatial Technologies and Human Rights Project at AAAS, said in a statement.

Damage to the other five sites is extensive, the AAAS said. These sites include the ancient city of Aleppo, the ancient city of Bosra, the ancient site of Palmyra, a site with two castles (Crac des Chevaliers and Qal'at Salah El-Din), and the ancient villages of northern Syria (Jebel Seman, Jebel Barisha, Jebel Al A'la, Jebel Wastani and Jebel Zawiye.

The analysis showed widespread damage in Aleppo, one of the oldest continuously occupied cities in the world, which dates back to the second millennium B.C.

A before-and-after analysis from 2011 to 2014 indicates new damage to historic mosques, Koranic schools called madrasas, the Great Mosque of Aleppo, the Souq al-Madina, the Grand Serail of Aleppo, the Hammam Yalbougha an-Nasry, the Khusruwiye Mosque, the Carlton Citadel Hotel, the Khan Qurt Bey caravanserai and other historic buildings south and north of the citadel. 

The Great Mosque has extensive damage. Satellite imagery showed destruction of the roof and a destroyed minaret, or tall spire, as well as two craters on the mosque's eastern wall. Researchers saw the heaviest damage south of the citadel, but the area to the north, which has buildings from the late Mamluk to Ottoman periods (13th to 19th centuries) also showed signs of destruction.
The other World Heritage sites have damage ranging from mortar impacts near an ancient Roman theater in Bosra to newly constructed military compounds on an archaeological site. New roads and mounds of earth are scattered through the Northern Roman Necropolis in Palmyra.

Palmyra sits in a desert just northeast of Damascus. Its ruins combine Greco-Roman art with Persian influences, and UNESCO said it "contains the monumental ruins of a great city that was one of the most important cultural centers of the ancient world."

The AAAS released the analysis yesterday (Sept. 18), a day before the Smithsonian Institution's meeting to honor the 1954 Hague Convention for the Protection of Cultural Property. Researchers plan to discuss the damage and intervention efforts in Syria at the meeting.

"There is hope, and it lies with our Syrian colleagues because they are the stewards and caretakers of these sites, and they see the value in preserving and protecting them for future generations," said Corine Wegener, cultural heritage preservation officer for the Smithsonian Institution. "What they need from their international colleagues is some help to do that — training, materials and other support in the international arena for the notion that it is possible to mitigate and prevent damage to cultural heritage, even in the midst of conflicts."
