week 5 - Google achieves AI 'breakthrough' by beating Go champion

A Google artificial intelligence program has beaten the European champion of the board game Go.
The Chinese game is viewed as a much tougher challenge than chess for computers because there are many more ways a Go match can play out.
The tech company's DeepMind division said its software had beaten its human rival five games to nil.
One independent expert called it a breakthrough for AI with potentially far-reaching consequences.
The achievement was announced to coincide with the publication of a paper, in the scientific journal Nature, detailing the techniques used.
Earlier on Wednesday, Facebook's chief executive had said its own AI projecthad been "getting close" to beating humans at Go.
But the research he referred to indicated its software was ranked only as an "advanced amateur" and not a "professional level" player.Go is thought to date back to ancient China, several thousand years ago.
Using black-and-white stones on a grid, players gain the upper hand by surrounding their opponents pieces with their own.
The rules are simpler than those of chess, but a player typically has a choice of 200 moves compared with about 20 in chess.
There are more possible positions in Go than atoms in the universe, according to DeepMind's team.
It can be very difficult to determine who is winning, and many of the top human players rely on instinct.DeepMind's chief executive, Demis Hassabis, said its AlphaGo software followed a three-stage process, which began with making it analyse 30 million moves from games played by humans.
"It starts off by looking at professional games," he said."It learns what patterns generally occur - what sort are good and what sort are bad. If you like, that's the part of the program that learns the intuitive part of Go.
"It now plays different versions of itself millions and millions of times, and each time it gets incrementally better. It learns from its mistakes.
"The final step is known as the Monte Carlo Tree Search, which is really the planning stage.
"Now it has all the intuitive knowledge about which positions are good in Go, it can make long-range plans."
Tested against rival Go-playing AIs, Google's system won 499 out of 500 matches,
And last October, DeepMind invited Fan Hui, Europe's top player, to its London office for a series of games, each of which the AI won.
"Many of the best programmers in the world were asked last year how long it would take for a program to beat a top professional, and most of them were predicting 10-plus years," Mr Hassabis said.
"The reasons it was quicker than people expected was the pace of the innovation going on with the underlying algorithms and also how much more potential you can get by combining different algorithms together."

week 4 - Taiwan Earthquake: 116 confirmed dead in Tainan as search for survivors concluded

A rescue operation taking place after the Taiwan earthquake has been concluded as the remains of the last unaccounted for person was pulled from the wreckage of the Weiguan Jinlong apartment complex. In total 116 people have been confirmed dead after the powerful 6.4-magnitude earthquake, with all but two of the victims living at the 17-storey Weiguan Jinlong (Golden Dragon) building.
The earthquake struck the southern Taiwanese city of Tainan on 7 February leaving the city strewn with twisted metal, fallen bricks and concrete debris. The city had a population of 1.9 million people and on Friday 12 February, the president and president-elect attended a memorial service for the dead and missing.
Tainan City mayor William Lai announced an end to the operation on Saturday (13 February) as the remains of Hsieh Chen-yu were discovered at 3.57pm local time. In total 289 people were pulled out of the collapsed building with 173 still alive and 96 remain in hospital.
Although residents lived in the upper regions of the complex, its lower storeys were filled with arcades of shops which initially gave way under the strain of the quake before the whole of the U-shaped construction was destroyed. The last survivor was dragged out of the wreckage on Monday evening (8 February).
The Taiwanese government immediately launched an investigation into the construction of the building complex after blue cans were pictured – reportedly used as construction fillers in the beams. Reports from the city suggest that the residents living in the building, constructed in 1989, had often complained of problems like tiles falling from walls, malfunction of lifts and the building having too few reinforcing bars.
Lin Ming-hui, former chairman of the now disbanded Weiguan company, and two other former executives Chang Kui-an and Cheng Chin-kui now face charges of professional negligence resulting in death after appearing in court on Wednesday 10 February.
Hsieh, a member of the blocks management committee "might have wanted to wait until everyone else had left", Lai said, according to the Central News Agency. He added that the: "The search and rescue has come to an end".

week 3 - Oxford Dictionaries Word of the Year 2015 is…

That’s right – for the first time ever, the Oxford Dictionaries Word of the Year is a pictograph: 😂, officially called the ‘Face with Tears of Joy’ emoji, though you may know it by other names. There were other strong contenders from a range of fields, outlined below, but 😂 was chosen as the ‘word’ that best reflected the ethos, mood, and preoccupations of 2015.

Why was this chosen?

Emojis (the plural can be either emoji or emojis) have been around since the late 1990s, but 2015 saw their use, and use of the word emoji, increase hugely.  This year Oxford University Press have partnered with leading mobile technology business SwiftKey to explore frequency and usage statistics for some of the most popular emoji across the world, and 😂 was chosen because it was the most used emoji globally in 2015. SwiftKey identified that 😂 made up 20% of all the emojis used in the UK in 2015, and 17% of those in the US: a sharp rise from 4% and 9% respectively in 2014. The wordemoji has seen a similar surge: although it has been found in English since 1997, usage more than tripled in 2015 over the previous year according to data from the Oxford Dictionaries Corpus.
A brief history of emoji
An emoji is ‘a small digital image or icon used to express an idea or emotion in electronic communication’; the term emoji is a loanword from Japanese, and comes from e ‘picture’ + moji ‘letter, character’. The similarity to the English word emoticon has helped its memorability and rise in use, though the resemblance is actually entirely coincidental:emoticon (a facial expression composed of keyboard characters, such as ;), rather than a stylized image) comes from the English words emotion and icon.
Emojis are no longer the preserve of texting teens – instead, they have been embraced as a nuanced form of expression, and one which can cross language barriers. Even Hillary Clinton solicited feedback in the form of emojis, and 😂 has had notable use from celebrities and brands alongside everyone else – and even appeared as the caption tothe Vine which apparently kicked off the popularity of the term on fleek, which appears on our WOTY shortlist.

week 2 - Protesters Are in Agreement as Well: Pact Is Too Weak

PARIS — Several thousand climate activists from across Europe and many from farther afield gathered peacefully near the Arc de Triomphe on Saturday to protest the outcome of the COP 21 climate conference about 12 miles away.
The demonstration was an official exception to a ban on public gatheringsacross France after the Paris terrorist attacks in November.
Even as the delegates at the official conference center reached a landmark accord and applauded their achievement, the crowds on the street made clear their belief that it would take much more than the measures in the deal to halt global climate change.
“We don’t like the COP 21,” said Joseph Purugganan, who came from the Philippines to participate in the demonstration with other activists from a coalition called Focus on the Global South.
“The message here is that the real solution will come from the people,” he said. “After 20 years of COPs, look at where we are.”
He added that slowing the increase in global temperatures to 1.5 degrees Celsius (2.7 degrees Fahrenheit) by 2100, the goal set in the agreement, was not enough. In the Philippines, there have been record typhoons, and fishermen in Southeast Asia are being driven from their homes by rising oceans, he said.

Stuart Basden, 33, who came from Toronto, sounded even more disappointed. “We knew that it would be a failure,” he said. “They just decided in which decade we will become extinct.”
In contrast to an earlier protest during the conference, a banned one at the Place de la République on Nov. 29 that turned violent and resulted in arrests, the mood at the Arc de Triomphe was cheerful, even festive. Almost everyone carried a red tulip, and many waved flags or carried banners, or had more creative props.
A group of Danes dressed as polar bears took off their headgear periodically to get some air and see the events around them, while a group from Peru waved flags, one of which said “Nuclear Power, Non Gracias.”
At two locations, the Arc de Triomphe and the Champ de Mars, the climate demonstrators unfolded and carried two 100-meter red ribbons — red to symbolize that the climate situation is an emergency, and to communicate their skepticism toward the agreement. The Arc de Triomphe demonstration was organized by 350.org, a United States-based climate change nonprofit. The one at the Champs de Mars was organized by a coalition of 16 environmental groups, including the French chapters of Friends of the Earth and Attac. Many participants said that the event and even the conference had energized many climate change activists, regardless of its outcome.
There was also an unofficial demonstration earlier Saturday in which about 3,000 climate activists in Paris managed to use geo-localization technology to spell out the words “Climate Justice Peace” on a virtual map.
“The climate movement is growing, and climate policies now have a huge mainstream support,” said Daniel Smith, 29, who bicycled from London to join the demonstration.
Standing next to his bike, which had a globe strapped to the back, he added, “And now it’s not green anymore, it’s red.”
A group of climate activists from the Netherlands had come by bus. One, Willemyn Kadyk, 19, a college student and aspiring environmental lawyer, said that while many might not care much about demonstrations, such events were an important counterpoint to the official conference.
“People might think it’s not worth it to come, but if everybody thinks that way, nothing changes,” she said. “Groups will make this change.”
Many French activists were there, as well, including Corine Lefort, an elementary school principal who came from Marseille with her husband. They carried a banner that read “Save the Climate.”
“This is to put pressure on those officials responsible that things need to change more quickly,” she said. “It’s urgent. This is a real crime against humanity.”
She added that on the Mediterranean coast there were already villages where people living close to the water had deserted their homes because the sea had risen.
“This is not something for the future,” she said. “The future is already here.”

week 1 - State-of-art opera house opens in central Taiwan

TAIPEI -- Central Taiwan's first opera house opened Sunday with a grand ceremony to inaugurate what Culture Minister Lung Ying-tai called "the pride of Taichung."
Designed by Pritzker Architecture Prize-winning Japanese architect Toyo Ito, the eye-catchingly modern National Taichung Theater boasts a 2,014-seat grand theater, a 800-seat theater and a 200-seat black box.
The architecturally complex theater was an engineering challenge constructed entirely without beams or columns and relying instead on 58 curved wall units. It is believed to be the first theater in the world to employ such a construction technique.
While the outside walls appear to be smooth surfaces thanks to the installation of glass windows, the basic structure itself is a series of tubular voids connected together.
Called a "sound cave" by Ito, the state-of-the-art opera house took nearly 5 years to complete at a cost of NT$4.36 billion (US$141 million).
President Ma Ying-jeou, who attended the inauguration ceremony, expressed hope that the theater will help his administration reach its goal of "rejuvenating the country through culture."
He gave credit to Taichung Mayor Jason Hu, who is up for reelection next week, for turning the daunting architectural challenge into a reality.
Culture Minister Lung, meanwhile, thanked the workers who helped construct the building along with city government employees.
A series of performances by prominent local groups will take place at the opera house starting this month to celebrate its inauguration.
The series begins Sunday with a production of "Cat Man" by Taiwanese opera troupe Ming Hwa Yuan Arts and Cultural Group.
Paper Windmill Theatre will then perform its production of "Don Quixote" Nov. 27 and Nov. 28, which will be followed by a concert by Taiwanese violinist Hu Nai-yuan and the Taiwan Connection Chamber Orchestra on Dec. 7.
Ju Percussion Group will then give a performance on Dec. 13.
The National Taichung Theater is part of the government's efforts to strengthen support for and improve the quality and international competitiveness of Taiwan's performing arts.
It is being touted as a leg of the "golden triangle" for the performing arts in Taiwan, alongside Taipei's National Theater and Concert Hall and Kaohsiung's Wei-Wu-Ying Center for the Arts, the latter of which is set to be completed next year.
The Ministry of Culture will take over the operation of the National Taichung Theater starting in January next year.

week5 - Water on Mars: Exploration & Evidence ( NASA:證實火星有流動的液態鹽水 )

Water on Mars: Exploration & Evidence

Liquid water may still flow on Mars, but that doesn't mean it's easy to spot. The search for water on the Red Planet has taken more than 15 years to turn up definitive signs that liquid flows on the surface today. In the past, however, rivers and oceans may have covered the land. Where did all of the liquid water go? Why? How much of it still remains?

Observations of the Red Planet indicate that rivers and oceans may have been prominent features in its early history. Billions of years ago, Mars was a warm and wet world that could have supported microbial life in some regions. But the planet is smaller than Earth, with less gravity and a thinner atmosphere. Over time, as liquid water evaporated, more and more of it escaped into space, allowing less to fall back to the surface of the planet.

Where is the water today?

Liquid water appears to flow from some steep, relatively warm slopes on the Martian surface. First identified in 2011, features known as recurring slope lineae (RSL) were confirmed to be signs of salty water running on the surface of the planet today. The dark streaks appear seasonally on Martian slopes were found in images taken by the High Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO) Spectral analysis of RSL lead scientists to conclude they are caused by salty liquid water.

"The detection of hydrated salts on these slopes means that water plays a vital role in the formation of these streaks," the study's lead author, Lujendra Ojha, of the Georgia Institute of Technology in Atlanta, said in a statement.

Vast deposits of water appear to be trapped within the ice caps at the north and south poles of the planet. Each summer, as temperatures increase, the caps shrink slightly as their contents skip straight from solid to gas form, but in the winter, cooler temperatures cause them to grow to latitudes as low as 45 degrees, or halfway to the equator. The caps are an average of 2 miles (3 kilometers) thick and, if completely melted, could cover the Martian surface with about 18 feet (5.6 meters) of water.

Frozen water also lies beneath the surface. Scientists discovered a slab of ice as large as California and Texas combined in the region between the equator and north pole of the Red Planet. The presence of subsurface water has long been suspected but required the appearance of strange layered craters to confirm. Other regions of the planet may contain frozen water, as well. Some high-latitude regions seem to boast patterned ground-shapes that may have formed as permafrost in the soil freezes and thaws over time.

The European Space Agency's Mars Express spacecraft captured images of sheets of ice in the cooler, shadowed bottoms of craters, which suggests that liquid water can pool under appropriate conditions. Other craters identified by NASA's Mars Reconnaissance Orbiter show similar pooling.


Evidence for water on Mars first came to light in 2000, with the appearance of gullies that suggested a liquid origin. Their formation has been hotly debated over the ensuing years.

Week 3 - Stay Hungry. Stay Foolish. ( 賈伯斯在史丹佛大學畢業典禮上的演說 )

I am honored to be with you today at your commencement from one of the finest universities in the world. I never graduated from college. Truth be told, this is the closest I've ever gotten to a college graduation. Today I want to tell you three stories from my life. That's it. No big deal. Just three stories.

The first story is about connecting the dots.

I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another 18 months or so before I really quit. So why did I drop out?

It started before I was born. My biological mother was a young, unwed college graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: "We have an unexpected baby boy; do you want him?" They said: "Of course." My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers. She only relented a few months later when my parents promised that I would someday go to college.

And 17 years later I did go to college. But I naively chose a college that was almost as expensive as Stanford, and all of my working-class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked interesting.

It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned Coke bottles for the 5¢ deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on. Let me give you one example:

Reed College at that time offered perhaps the best calligraphy instruction in the country. Throughout the campus every poster, every label on every drawer, was beautifully hand calligraphed. Because I had dropped out and didn't have to take the normal classes, I decided to take a calligraphy class to learn how to do this. I learned about serif and sans serif typefaces, about varying the amount of space between different letter combinations, about what makes great typography great. It was beautiful, historical, artistically subtle in a way that science can't capture, and I found it fascinating.

None of this had even a hope of any practical application in my life. But 10 years later, when we were designing the first Macintosh computer, it all came back to me. And we designed it all into the Mac. It was the first computer with beautiful typography. If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts. And since Windows just copied the Mac, it's likely that no personal computer would have them. If I had never dropped out, I would have never dropped in on this calligraphy class, and personal computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backward 10 years later.

Again, you can't connect the dots looking forward; you can only connect them looking backward. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.

My second story is about love and loss.

I was lucky — I found what I loved to do early in life. Woz and I started Apple in my parents' garage when I was 20. We worked hard, and in 10 years Apple had grown from just the two of us in a garage into a $2 billion company with over 4,000 employees. We had just released our finest creation — the Macintosh — a year earlier, and I had just turned 30. And then I got fired. How can you get fired from a company you started? Well, as Apple grew we hired someone who I thought was very talented to run the company with me, and for the first year or so things went well. But then our visions of the future began to diverge and eventually we had a falling out. When we did, our Board of Directors sided with him. So at 30 I was out. And very publicly out. What had been the focus of my entire adult life was gone, and it was devastating.

I really didn't know what to do for a few months. I felt that I had let the previous generation of entrepreneurs down — that I had dropped the baton as it was being passed to me. I met with David Packard and Bob Noyce and tried to apologize for screwing up so badly. I was a very public failure, and I even thought about running away from the valley. But something slowly began to dawn on me — I still loved what I did. The turn of events at Apple had not changed that one bit. I had been rejected, but I was still in love. And so I decided to start over.

I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.

During the next five years, I started a company named NeXT, another company named Pixar, and fell in love with an amazing woman who would become my wife. Pixar went on to create the world's first computer animated feature film, Toy Story, and is now the most successful animation studio in the world. In a remarkable turn of events, Apple bought NeXT, I returned to Apple, and the technology we developed at NeXT is at the heart of Apple's current renaissance. And Laurene and I have a wonderful family together.

I'm pretty sure none of this would have happened if I hadn't been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life hits you in the head with a brick. Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don't settle.

My third story is about death.

When I was 17, I read a quote that went something like: "If you live each day as if it was your last, someday you'll most certainly be right." It made an impression on me, and since then, for the past 33 years, I have looked in the mirror every morning and asked myself: "If today were the last day of my life, would I want to do what I am about to do today?" And whenever the answer has been "No" for too many days in a row, I know I need to change something.

Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure — these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

About a year ago I was diagnosed with cancer. I had a scan at 7:30 in the morning, and it clearly showed a tumor on my pancreas. I didn't even know what a pancreas was. The doctors told me this was almost certainly a type of cancer that is incurable, and that I should expect to live no longer than three to six months. My doctor advised me to go home and get my affairs in order, which is doctor's code for prepare to die. It means to try to tell your kids everything you thought you'd have the next 10 years to tell them in just a few months. It means to make sure everything is buttoned up so that it will be as easy as possible for your family. It means to say your goodbyes.

I lived with that diagnosis all day. Later that evening I had a biopsy, where they stuck an endoscope down my throat, through my stomach and into my intestines, put a needle into my pancreas and got a few cells from the tumor. I was sedated, but my wife, who was there, told me that when they viewed the cells under a microscope the doctors started crying because it turned out to be a very rare form of pancreatic cancer that is curable with surgery. I had the surgery and I'm fine now.
                                                                                                                             
This was the closest I've been to facing death, and I hope it's the closest I get for a few more decades. Having lived through it, I can now say this to you with a bit more certainty than when death was a useful but purely intellectual concept:

No one wants to die. Even people who want to go to heaven don't want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life's change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.

Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma — which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.

When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation. It was created by a fellow named Stewart Brand not far from here in Menlo Park, and he brought it to life with his poetic touch. This was in the late 1960s, before personal computers and desktop publishing, so it was all made with typewriters, scissors and Polaroid cameras. It was sort of like Google in paperback form, 35 years before Google came along: It was idealistic, and overflowing with neat tools and great notions.

Stewart and his team put out several issues of The Whole Earth Catalog, and then when it had run its course, they put out a final issue. It was the mid-1970s, and I was your age. On the back cover of their final issue was a photograph of an early morning country road, the kind you might find yourself hitchhiking on if you were so adventurous. Beneath it were the words: "Stay Hungry. Stay Foolish." It was their farewell message as they signed off. Stay Hungry. Stay Foolish. And I have always wished that for myself. And now, as you graduate to begin anew, I wish that for you.

Stay Hungry. Stay Foolish.

Thank you all very much.
