【推荐1】What defines an eco-house? There are two features to take into consideration. Firstly, the energy efficiency and carbon emissions associated with running the house, and then the type of construction materials used, their associated emissions and the raw materials required.

At Baufritz, we have won awards relating to the sustainability of our houses. This is because as a company we had decided to put environmental stewardship at the core of our values way back in the 1960s. So how do we do it?

Heating is the biggest emissions factor for any house. It is really rather simple to solve this problem — make a house extremely energy efficient and this will no longer be a factor. Ultra low energy houses have become known as Passive houses, where a certain set of design characteristics help to improve efficiencies. You need a very high level of insulation in the walls and roof. Glass should be suitably positioned to optimize solar gaintucmrr (heat from the sun). The house needs to be very well engineered so no heat is lost through cracks or poorly fitted windows and doors. At Baufritz we manufacture Kit houses, and use Modern Manufacturing Methods in our factory to engineer our houses in such a way that leaks are minimized.

We have also developed “HOIZ” insulation. Manufactured from natural wood waste products, HOIZ is placed between the inside and outside layers of our timber framed houses to create the highest level of insulation. Our windows and doors use triple glazing to minimize heat loss. Overheating is one of the biggest challenges Passive houses face and our architects use some very clever ventilation systems   to manage   internal   environmental   conditions.   All   houses   still   have   energy-consuming appliances, but with the addition of solar for both electricity generation and water heating, the carbon footprint of the homes we produce are further reduced.

Embedded carbon in building manufacturing materials such as concrete, as well as a historic tendency to send materials to landfills, results in a high carbon footprint and natural resource exploitation. Baufritz addresses this problem in a number of ways. Our primary manufacturing material is wood. We source from sustainable certified forests where felled trees are replanted. In fact, we believe all building materials should be as natural as possible. We say no to PU construction foams, chemical insulation materials, toxic adhesives and laminate flooring. A house constructed using only natural materials creates a healthy living environment for its residents. As all our houses are manufactured in our state-of-the-art factory, waste is kept to an absolute minimum. At the end of their life-cycle, our houses can also be recycled. Today, demolition（拆除）firms clearing the site for the new build are able to recycle nearly all of the building materials, therefore closing the manufacturing loop.

My house is old, so why is this relevant? There are still lots of things which can be done. Improve your insulation. When your appliances expire, replace based on efficiency. Consider heat pumps instead of gas boilers and explore solar to deliver electricity and water heating. By designing and building houses to ultra low energy standards, and by using natural sustainably sourced materials and recycling the waste products from our manufacturing processes, we are able to deliver Carbon Neutral Houses. This means that the total carbon footprint throughout the life-cycle of each house is zero, which is why we call ourselves eco-house pioneers. All houses are prefabricated at our state-of-the-art factory in Erkheim, Germany, and then assembled on site.

【推荐2】Parallel worlds exist and interact with our world, say physicists.

Quantum mechanics (量子力学), though firmly tested, is so weird and anti-intuitive that physicist Richard Feynman once remarked, “I think I can safely say nobody understands quantum mechanics.” Attempts to explain some of the bizarre (奇异的) consequences of quantum theory have led to some mind-bending ideas, such as the Copenhagen interpretation and the many-worlds interpretation.

Now there’s a new theory on the block, called the “many interacting worlds” hypothesis (假设) (MIW), and the idea is just as profound as it sounds. The theory suggests not only parallel worlds exist, but that they interact with our world on the quantum level and are thus detectable. Though still speculative (推测的), the theory may help to finally explain some of the bizarre consequences inherent in quantum mechanics.

The theory is a spinoff of the many-worlds interpretation in quantum mechanics—an assumption that all possible alternative histories and futures are real, each representing an actual, though parallel, world. One problem with the many-worlds interpretation, however, has been that it is fundamentally untestable, since observations can only be made in our world. Happenings in these proposed “parallel” worlds can thus only be imagined.

MIW, however, says otherwise. It suggests that parallel worlds can interact on the quantum level, and in fact that they do.

“The idea of parallel universes in quantum mechanics has been around since 1957,” explained Howard Wiseman, a physicist at Griffith University in Brisbane, Australia, and one of the physicists to come up with MIW. “In the well-known ‘Many-Worlds Interpretation’, each universe branches into a bunch of new universes every time a quantum measurement is made. All possibilities are therefore realized — in some universes the dinosaur-killing asteroid (小行星) missed Earth. In others, Australia was colonized by the Portuguese.”

“But critics question the reality of these other universes, since they do not influence our universe at all,” he added. “On this score, our ‘Many Interacting Worlds’ approach is completely different, as its name implies.”

Wiseman and colleagues have proposed that there exists “a universal force of repulsion between ‘nearby’(i.e. similar) worlds, which tends to make them more dissimilar.” Quantum effects can be explained by factoring in this force, they propose.

When asked about whether their theory might imply that humans could someday interact with other worlds, Wiseman said: “It’s not part of our theory. But the idea of human interactions with other universes is no longer pure fantasy.”

What might your life look like if you made different choices? Maybe one day you'll be able to look into one of these alternative worlds and find out.

【推荐3】They have beaten us at chess, and now computers are taking a step into a very human territory: the reading comprehension test, which schoolchildren everywhere are suffering.

Alibaba said its artificial research outperformed mere mortals (凡人) in a global reading test that seeks answers to such pressing questions as “what was Nikola Tesla’s ethnicity?” and “how big is the Amazon rainforest?”

Luo Si referred to the machines' victory as “a milestone”. He said the technology has many uses, from customer service to museum tutorials to medical enquires-some of which are already being handled by chatbots (聊天机器人)   globally.

In the test, companies subjected their artificial intelligence systems to queries from the Stanford Question Answering Dataset, which assessed reading comprehension. The computers' answers were compared against average human responses and ranked.

Tying in top place were Microsoft, the US software giant, and Alibaba, the Chinese tech group that began with ecommerce and--like its peers at home and abroad---is ploughing more funds into AI, much of it via its research arm.

While Microsoft and Alibaba won by the slimmest of margins---at accuracy levels a few basis points above humans’ 82.3 per cent in providing exact matches to questions--the tie provided a fitting symbol of the AI arms race between the US and China.

China aims to use its vast troves （宝库）of data, collected from its 1.4 billion population including 730 million who are online, and deep pockets to overtake the US in creating a $150 billion industry that is seen as the next industrial revolution. AI is already being harnessed in everything from driverless cars to customising newsfeeds.

While China’s drive is being spearheaded by government, it is cultivating homegrown tech giants including Baidu, Alibaba and Tencent to leap ahead of the US.

Baidu made an early bet on AI, and is leading its rivals in autonomous driving. Tencent, which boasts just shy of 1 billion monthly active users on its social media WeChat app, and Alibaba have adopted AI in operations such as customizing news and ads, and are investing in new fields.

【推荐1】People may set an alarm on the phone or clock that sounds like this: beep beep beep. That hard, unpleasant sound may be making it harder to shake off the sleepy feeling in the morning known as grogginess. So, is there a better way to wake up? A recent study says yes. The answer is music.

The study, carried out by researchers in Australia, involved 50 people. The researchers found that people who wake up to musical alarms reported feeling more awake and alert. Stuart McFarlane, a lead writer of the study stated, “We are very surprised by these findings as one might expect a harsh beeping sound to be more successful,” at waking up a person.

Sleep inertia is another term for grogginess. It means a person has a heavy feeling when waking up, and has trouble getting moving again after sleeping. McFarlane said people need to better understand sleep inertia’s harmful effects on human performance later in the day.

Not everyone will experience the full effect. But for those who do, “care should be taken” when performing duties that require a top performance within this period, he said. This includes “dangerous tasks like driving or riding our bikes” shortly after waking up. The same is true for people who work in dangerous situations shortly after they wake, including firefighters and pilots.

So, what makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a “beeping” alarm. McFarlane said that the changes over time between the music tones may help increase a person’s attention when waking from sleep.

And is there a kind of music that is best to wake up to? There may be, McFarlane said. “We could suggest alarm sounds that are tune full and easy to hum or sing along with. The current sounds I have been using include ‘Close to me’ by the Cure and ‘Borderline’ by Madonna.”

No matter how you wake up, experts say, the amount of sleep you get also matters a lot.

【推荐2】At 12, my father decided to take me on a trip to France. I had never been out of the country before, so I was very excited. My aunt, my father and I went around with my father showing us all the unbelievable sites in Paris. None of us spoke much French but we loved the city.

We had taken the subway all over the city and were congratulating ourselves on our mastering what is honestly an excellent subway design that is pretty easy to follow. We decided visit Versailles by train. We chatted happily along the way until my father realized we were into the French countryside and no one around spoke English.

We reached the end of the line and felt afraid when everyone finally left the train. An old man and his grandchild noticed us and came to help. He spoke no English, so in broken French we tried to explain. When he finally understood, this great man settled his grandson and showed us to the correct train and then boarded with us.

Later we knew the truth that there was a train transfer (转乘) and he didn't want us to miss it.

This kind man rode a train for an hour and a half out of his way to make sure that three Americans got where they wanted to be. He refused to let us pay for his ticket. He did it all with a gentle smile and patted our hands gently at the stop. Then in his quiet way, he boarded the train to return the way he had come.

What impressed me most was the man and his kindness during the amazing trip. Some Americans think the French are rude for some reason, but I always try to persuade them to change their minds with this very story.

【推荐3】It is natural that young people are often uncomfortable(不自在) when they are with their parents. They say that their parents don’t understand them. They often think that their parents are out of touch with modern ways; that they are too serious and too strict with their children; and that they seldom give their children a free hand.

It is true that parents often find it difficult to win their children’s trust and they tend to forget how they themselves felt when young. They show that they have grown up and they can face any difficult situation. Older people worry more easily. Most of them plan things ahead, at least in the back of their minds, and do not like their plans to be upset(扰乱) by something unexpected.

When you want your parents to let you do something, you will have better success if you ask before you really start doing it.

Young people often make their parents angry with their choices in clothes, in entertainment and in music. But they do not mean to cause any trouble; it is just that they feel cut off from the older people’s world, into which they have not yet been accepted. That’s why young people want to make a new culture(文化) of their own. And if their parents do not like their music or entertainment or clothes or their way of speech, this will make the young people extremely happy.

Sometimes you are so proud of yourself that you do not want your parents to say “yes” to what you do. All you want is to be left alone and do what you like. It is natural enough, after being a child for so many years, when you were completely under your parents’ control.

If you plan to control your life, you’d better win your parents over and try to get them to understand you. If your parents see that you have a high sense of responsibility(责任), they will certainly give you the right to do what you want to do.
