里約奧運

  • Ethiopian swimmer Robel Kiros Habte became an Olympic sensation on Tuesday for all the wrong reasons.
    Habte, a 24-year-old who qualified for the Olympics because of a special invitation from the International Swimming Federation to athletes from underrepresented countries, finished with the worst time of 59 swimmers in the 100 freestyle.
    In his three-man heat, Habte — who also gained attention for his physique — finished with a time of 1 minute 4.95 seconds, which was more than 12 seconds behind Thibaut Danho of the Ivory Coast and 13 behind Jhonny Perez Urena of the Dominican Republic. He was 17 seconds slower than Australian leader Kyle Chalmers, who finished in 47.9 seconds.
    Habte was the only swimmer to not complete the event in under a minute.
    He instantly became a fan favorite, drawing (somewhat unfair) comparisons to Eric "the Eel" Moussambani of Equatorial Guinea, who finished with a time of 1:57 in the 2000 Olympics. The crowd began cheering for Habte as he approached the finish while his competition was resting, waiting for him.
  • But if you think Habte is upset by his poor performance, you're wrong. In fact, his upbeat approached makes the story all the better.
    "I am so happy because it is my first competition in the Olympics," Habte said (via Reuters). "So thanks for God."
    He continued, saying his goal was to stand out from his fellow countrymen.
  • "I wanted to do something different for my country. That's why I chose swimming," Habte said. "Everybody, every day you wake up in Ethiopia, you run. Not swimming. But I didn't want to run. I wanted to be a swimmer. It didn't matter where I finished."
    Habte indeed is enjoying his time in the Olympics. On what appears to be his Facebook page, Habte has been showing off his Olympic experiences, like meeting Ryan Lochte, carrying the Ethiopian flag, and rocking Rio attire in general.
    According to Reuters, Habte "has no plans on competing again, but he will always be an Olympian."

Samsung is having some trouble identifying what went wrong with the Galaxy Note 7, which earlier this year was recalled due to a high number of battery explosions, but someone else believes they have the answer. Manufacturing engineering company Instrumental has performed a teardown of the device, and found that the battery simply did not have enough physical room for error.


The problem had more than one factor, the teardown found. A phone battery is made up of positive and negative layers, with separators to keep them from touching and sparking. In order to streamline the size of the battery and maximise space, these separators may have been too thin. Moreover, Samsung made the battery thinner, removing thickness margins.

When batteries are charged, they swell a little. Around 10 percent extra space is required, but the battery entirely filled its 5.2-millimetre-deep pocket, with very little space around the edges. Add the normal pressures of day-to-day handling, and the risk of explosion goes up.

“Looking at the design,Samsung engineers were clearly trying to balance the risk of a super-aggressive manufacturing process to maximize capacity, while attempting to protect it internally,” the teardown reads. “Samsung took a deliberate step toward danger, and their existing test infrastructure and design validation process failed them.”  When batteries are charged, they swell a little.

白頭盔

The White Helmets are internationally recognised for their rescue efforts, and have been nominated for the "real" Nobel Peace Prize, which will be announced in October.
Syrian President Bashar al-Assad, however, downplayed the importance of the organisation's work.
In an interview with the APTN news agency, Mr Assad asked: "What did they achieve in Syria?
"How unpoliticised is the Nobel Prize? That's the other question," he said.
"I would only give a prize to whoever worked for the peace in Syria first of all by stopping the terrorists from blowing war on Syria, only."

What are the White Helmets?

  • started early 2013 as a volunteer workforce
  • includes bakers, tailors, carpenters, electricians
  • 130 killed out of about 3,000 members
  • say they are neutral, have no political affiliation and save people from all sides of conflict
  • also do repair works, reconnect electrical cables and secure the buildings
  • run by donations, also helped by US Aid and Dutch foreign ministry

In a statement announcing the laureates, the award's organisers said the Syria Civil Defence's "deep commitment to humanitarian action" had "drawn international attention to the plight of Syria's citizens and the devastation caused by barrel bombs".
Speaking about all four recipients, executive director of the prize, Ole von Uexkull, said: "We do not only celebrate their courage, compassion and commitment; we also celebrate the success of their work, against all odds, and the real difference they are making in the world today."
In response to the award, the group tweeted that it was "humbled" and "proud".
The White Helmets are also the subject of a documentary film released on streaming service Netflix earlier this month.
Previous winners of the Right Livelihood Award include US intelligence leaker Edward Snowden, Alan Rusbridger, editor of UK newspaper The Guardian, and Gino Strada, an Italian war surgeon.

上海迪士尼

Walt Disney Co.’s $5.5 billion Shanghai theme park, its first in mainland China, opened with fireworks, a dancing Mickey Mouse, dignitaries and messages of support from two of the most powerful presidents in the world.
“I hope that Shanghai Disney can provide visitors with safe and premium experiences and become a world class theme park. I hope it promotes exchanges across cultures of the world,” according to a letter from Chinese President Xi Jinping, read by Vice Premier Wang Yang at the park’s opening ceremony Thursday morning.
Tens of thousands streamed into Shanghai Disneyland on its debut, an event that was nearly two decades in the making. The resort is the largest foreign investment ever for the Burbank, California-based company, as it intensifies the race to dominate China’s $610 billion tourism industry.
About 60 more parks will open by then to serve Chinese consumers, including Dalian Wanda Group Co.’s chain of 15 “Wanda Cities.” DreamWorks Animation SKG Inc’s $2.4 billion DreamCenter is scheduled for 2017, while Haichang Ocean Park Holdings plans a marine park an hour from Disneyland and Six Flags Entertainment Corp.’s Shanghai park will be its first outside North America. 
“The Shanghai resort shows the confidence of the international business community in China’s economic potential,” said Wang, one of the four vice premiers in the country’s State Council, in a speech as a drizzle fell during the ceremony. Rain marks “a good and auspicious start” according to Chinese culture, Wang said.
Amid the activities surrounding the Shanghai park debut, Iger offered his sympathies to the family of a child who died in an incident at Disney’s Grand Floridian Resort & Spa. The company said Thursday beaches in the Florida resort area remain closed until further notice after the death of the 2-year-old boy who was dragged by an alligator into a man-made lake.

China Bet

Iger, who is also the company’s chairman, first stepped foot on land that would become the Disney site in Shanghai’s Pudong district 17 years ago. The construction of the resort, a joint venture between Disney and the state-owned Shanghai Shendi Group, broke ground in 2011.
“It’s a big bet on a big market and it represents not only our biggest entrance into this market but the potential to deliver great growth for the company long term,” Iger said in a Bloomberg TV interview June 9.
Disney fell 0.1 percent to $98.27 by the close of trading in New York on Wednesday. The shares have fallen 6.5 percent this year, compared with the 1.3 percent gain in Standard and Poor’s 500 Index.
There’s big money at stake. About 25 percent of Chinese consumers surveyed in 2015 plan to spend more of their income on leisure and entertainment, according to a March report from McKinsey & Co. They’re also showing an increasing willingness to pay a premium for better goods, with half of those surveyed seeking the “best and most expensive” products.

Chinese Preferences

From the peony flower design on the turret of the park’s centerpiece castle, to a comedic Beijing opera interlude in the Mandarin version of the Lion King musical, Disney has taken pains to incorporate Chinese elements at the 963-acre resort. 

“We didn’t build Disneyland in China, we built China’s Disneyland,” said Iger.
Leia Mi, the concept designer for the Shanghai park’s castle, said that Disney conducted thorough market research into Chinese preferences. For example, while other Disneylands showcase a castle that guests walk through, the Shanghai park castle was designed with eating and retail space within them to meet Chinese expectations.
While the castles in Hong Kong and Anaheim are a tribute to the Disney character, Sleeping Beauty, the designers also chose to represent all the Disney princesses inside Shanghai’s castle. For most Chinese, there isn’t one Disney princess that stands out, Mi said.
“The Chinese can learn the princesses over time and this gives them an opportunity to have an introduction to all of the princess stories,” said executive producer Ali Rubinstein.

Most Ambitious

Disney’s designers and engineers said that the park was the grandest and most ambitious they have created, aided by new 3-D design technology that allowed them to identify and solve problems before construction began. 
“We certainly invented a few things for this in terms of technology development,” said the resort’s executive producer, Jodi Mclaughlin. “We worked hard to be very daring with this project and raise the bar in terms of what a Disney experience is. You’ll see things here that you won’t see any place else.”
At the park on Thursday, Su Xuanjun, a native of western Sichuan province, complained about the pricey tickets but gushed about an attraction based on the “Pirates of the Carribean” movie.
“It’s very impressive how they use technology in this ride,” said Su, who was accompanied by his wife, daughter and 4-year-old grandson. Still, he thinks Disney could have gone a bit further to make the park more “China-like”.
“Doesn’t look like China to me at all. They could have incorporated more Chinese elements,” said the 60-year-old retiree. “In the Pirates ride, they could have had the setting be the Yangtze River.”

火星探險

NASA'S MARS ROVER CURIOSITY IS BACK IN ACTION FOR THE FIRST TIME AFTER SUFFERING A GLITCH LATE LAST MONTH.

    The 1-ton Curiosity rover transferred powdered rock sample from its robotic arm to an analytical instrument on its body on Wednesday (March 11), and then drove about 33 feet (10 meters) toward the southwest on Thursday (March 12), NASA officials said.
Curiosity had been stationary since Feb. 27, when it experienced a short circuit while attempting to transfer the sample, which the rover had collected from a rock dubbed Telegraph Peak.
"That precious Telegraph Peak sample had been sitting in the arm, so tantalizingly close, for two weeks. We are really excited to get it delivered for analysis," Curiosity Project Scientist Ashwin Vasavada, of NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement.
Engineers have spent much of the past two weeks trying to figure out exactly what caused the short circuit. Testing suggests that it originated in the percussive mechanism for Curiosity's arm-mounted drill (which hammers as well as rotates to bore into rock).
The rover team will continue their analyses to determine how to proceed with future drilling work, NASA officials said.
Curiosity has performed six sample-collecting drilling operations since landing on Mars in August 2012. Analysis of some of these samples has helped rover scientists determine that the Red Planet could have supported microbial life in the ancient past.
Curiosity is moving away from an outcrop at the base of the towering Mount Sharp called Pahrump Hills, which the six-wheeled robot has been studying since last September. Curiosity will head to higher ground on Mount Sharp, via a valley called Artist's Drive.
"Road to Wellville: In good health, doing science & heading higher on Mt Sharp," NASA officials said Thursday via Curiosity's official Twitter account, @MarsCuriosity.
Mount Sharp has been Curiosity's prime science destination since before its November 2011 launch. The rover's handlers want Curiosity to climb up through the mountain's lower levels, reading a history of Mars' changing environmental conditions as it goes.
Curiosity transferred some Telegraph Peak powder to its Chemisty and Mineralogy instrument, or CheMin, on Wednesday. The rover will also deliver some of the sample to its Sample Analysis at Mars (SAM) instrument soon, NASA officials said.

What is Virtual Reality?

The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So the term ‘virtual reality’ basically means ‘near-reality’. This could, of course, mean anything but it usually refers to a specific type of reality emulation.
We know the world through our senses and perception systems. In school we all learned that we have five senses: taste, touch, smell, sight and hearing. These are however only our most obvious sense organs. The truth is that humans have many more senses than this, such as a sense of balance for example. These other sensory inputs, plus some special processing of sensory information by our brains ensures that we have a rich flow of information from the environment to our minds.
Everything that we know about our reality comes by way of our senses. In other words, our entire experience of reality is simply a combination of sensory information and our brains sense-making mechanisms for that information. It stands to reason then, that if you can present your senses with made-up information, your perception of reality would also change in response to it. You would be presented with a version of reality that isn’t really there, but from your perspective it would be perceived as real. Something we would refer to as a virtual reality.
So, in summary, virtual reality entails presenting our senses with a computer generated virtual environment that we can explore in some fashion.

In technical terms…

Answering “what is virtual reality” in technical terms is straight-forward. Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be explored and interacted with by a person. That person becomes part of this virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform a series of actions.

How is virtual reality achieved?

Although we talk about a few historical early forms of virtual reality elsewhere on the site, today virtual reality is usually implemented using computer technology. There are a range of systems that are used for this purpose, such as headsets, omni-directional treadmills and special gloves. These are used to actually stimulate our senses together in order to create the illusion of reality.
This is more difficult than it sounds, since our senses and brains are evolved to provide us with a finely synchronized and mediated experience. If anything is even a little off we can usually tell. This is where you’ll hear terms such asimmersiveness  and realism enter the conversation. These issues that divide convincing or enjoyable virtual reality experiences from jarring or unpleasant ones are partly technical and partly conceptual. Virtual reality technology needs to take our physiology into account. For example, the human visual field does not look like a video frame. We have (more or less) 180 degrees of vision and although you are not alwconsciously aware of your peripheral vision, if it were gone you’d notice. Similarly when what your eyes and the vestibular system in your ears tell you are in conflict it can cause motion sickness. Which is what happens to some people on boats or when they read while in a car.
If an implementation of virtual reality manages to get the combination of hardware, software and sensory synchronicity just right it achieves something known as a sense of presence. Where the subject really feels like they are present in that environment.

AlphaGo

Google's DeepMind artificial intelligence has secured its fourth win over a master player, in the final of a five match challenge.
Lee Se-dol, one of the world's top Go players, won just one of the matches against the AlphaGo program, missing out on the $1m prize up for grabs.
Demis Hassabis, founder of DeepMind, said the match had been the "most exciting and stressful" for his team.
Lee Se-dol said he felt "regrettable" about the result of the contest.
In Go, players take turn placing stones on a 19-by-19 grid, competing to take control of the most territory.
The game is considered to be much more challenging for computers than chess.
At a press conference held after the final match, Mr Lee said he did not necessarily think AlphaGo was superior to humans.
But he said he had more studying to do, and admitted the matches had challenged some of his ideas about the game Go.
In some countries the people watch football on big screens in public squares, but in South Korea it's been the mighty challenge of machine against humanity.
And the victory of the computer has led to some introspection.
One South Korean newspaper complained that the contest was "lopsided" with the single Korean pitted against the corporate might of Google and its "army of super-smart people armed with unfathomable computing power".
In a spirit of magnanimity, however, the Korea Baduk Association - which governs the game of Go - has decided to give an honorary ninth-dan ranking to AlphaGo.
The 4-1 mechanical victory has also made some Go players doubt themselves.
The European champion who lost last year to AlphaGo said it had really knocked his self-confidence, even as it enabled him to climb up the world rankings.
Go was invented about 2,500 years or so ago in China. Until now, it has always had a human best player. Not any more.

The five match challenge began in Seoul on 9 March, where AlphaGo scored its first victory.
After losing the second match, Lee Se-dol said he was "speechless" adding that the AlphaGo machine played a "nearly perfect game".
In the third game commentators said that Lee Se-dol had brought his "top game" but that AlphaGo had won "in great style".
DeepMind's winning streak meant it won the $1m (£702,000) prize on offer. Google said the money would be donated to Unicef, Stem (science, technology, engineering, and maths) charities and Go organisations.
Mr Hassabis said: "We have been lucky to witness the incredible culture and excitement surrounding Go.
"Despite being one of the oldest games in existence, Go this week captured the public's attention across Asia and the world."

Expertise

The AlphaGo system was developed by British computer company DeepMind which was bought by Google in 2014.
It has built up its expertise by studying older games and teasing out patterns of play.
Lee Se-dol did win the fourth match against AlphaGo, after which he said: "I've never been congratulated so much because I've won one game."
Despite Mr Lee's overall defeat, rival players have still expressed confidence that they could beat the AI.
Ahead of the final, China's top ranked Go master Ke Jie said he believed he could beat AlphaGo.
He told China Central Television: "In terms of probability, I have a chance to win, but the probability is not as high as I thought before. I think it is 60 per cent in favour of me."

Analysis by Dr Noel Sharkey, AI expert
To beat one of the world's top players, Deep Mind used a mixture of clever strategies to make the search much smaller.
Does this mean AI is now smarter than us and will kill us mere humans? Certainly not.
AlphaGo doesn't care if it wins or loses. It doesn't even care if it plays and it certainly couldn't make you a cup of tea after the game.
Does it mean that AI will soon take your job? Possibly you should be more worried about that.
