    Amazon is breaking into physical retail in a new way. The online retail giant revealed a new kind of physical store concept in a video published on Monday.

    The store, called Amazon Go, doesn't work like a typical Walmart or supermarket. Instead, it's designed so that shoppers will use an app, also called Amazon Go, to automatically add the products that they plan to buy to a digital shopping cart by scanning a QR code(二维码). They can then walk out of the building without waiting in a checkout line because Amazon will charge their Amazon account and send them a receipt.

    The first Amazon Go store is located in Seattle, where Amazon is headquartered. For years, there have been rumors the e-commerce company would expand its dominance from digital to physical shopping. Amazon began experimenting with physical bookstores a year ago, but Amazon Go may mark its boldest bet on physical ones yet. By removing much of the staff needed to operate a store, Amazon keeps costs lower than traditional competitors. It's also in a strong position to bring together data on its customers' shopping habits online and offline to make better suggestions in all situations.

    However, Amazon's move deeper into physical retail shops comes in a sensitive political climate. The company could be perceived as being a threat to some of the 3.4 million Americans who work as cashiers, according to the Bureau of Labor Statistics. On the campaign trail, Donald Trump repeatedly criticized Amazon and its founder Jeff Bezos for “getting away with murder tax-wise” and having “a huge antitrust(反垄断) problem.” Will the President& shy; elect add “job killer” to the list of criticisms?

    Amazon's effort to launch a new kind of retail store predates(在……之前) the rise of Donald Trump. “Four years ago we asked ourselves: what if we could create a shopping experience with no lines and no checkout? Could we push the boundaries of computer vision and machine learning to create a store where customers could simply take what they want and go?” The company says on an informational page about Amazon Go. For now, Amazon is starting slow. The Amazon Go is only open to Amazon employees in our Beta program, and is scheduled to open to the public in early 2017.

    The human brain remembers negative experiences more easily than positive ones. Our brains have developed this way because threats, like dangerous animals, had a more immediate effect on our ancestors' survival compared to positive things like food or shelter. As a result, you likely know what makes you unhappy, but do you know what makes you happy?

    Research suggests that our level of happiness depends partly on factors we cannot control—our genes and our life circumstances. But our level of happiness is also shaped by the choices we make. If you've been chasing wealth, fame, good looks, material things and power, you may be looking for happiness in all the wrong places. Psychologists suggest that the following habits make people happier.

    People who form close relationships tend to be happier than those who do not. The number of friends we have is not important. What matters is the quality of our relationships. Relationships that bring happiness usually involve the sharing of feelings, mutual respect, acceptance, trust and fun.

    People who exercise regularly improve both their physical and mental well being. Some research has shown that exercise can be as effective as medication in treating depression.

    When we are so interested in an activity we enjoy that we lose track of time, we are in a state of flow. The activity could be making art, playing piano, surfing, or playing a game. People who experience flow in their work or hobbies tend to be happier.

    People are more likely to be happy if they know what their strengths are and use them regularly, People who set goals and use their strengths to achieve them tend to be happier. People are especially happy when they can use their strengths to serve the greater good.

    People who think positively by being grateful, mindful and optimistic are more likely to be happy. Being grateful means being thankful, Bejing mindful means being open to, focusing on and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

    When I was growing up, Mother's Day was as important as Christmas.

    The energy around the house was always positive, mostly thanks to my father who made sure that his kids appreciated their mother. We would clean the house, and Mum got breakfast in bed in the morning and didn't have to lift a finger all day. And in the evening, we went to a restaurant for a traditional Mother's Day dinner.

    What I learned from my father over the years, was that no matter what, he always put my mother before himself. He absolutely loved her and never let her forget that.

    I maintain(保持) my father's Mother's Day tradition with my wife. Growing up, I learned that showing affection to the woman you love or who gave birth to you is an important part of life. You see, it goes both ways, and the love you have for your mother comes back to you again and again.

    Believing that and feeling it when you can may keep you from being lonely, even if your mum isn't close by or has passed away. There are a number of us who no longer have a mother in our lives, and truth be told, there are often times when I wish my mum were still here to comfort me. So instead, I remember the times she did just that. It makes me smile, and somehow, those memories of a more simple and loving life give me the comfort I'm looking for.

    If you are mum-less, you too should find a deserving woman in your life and celebrate Mother's Day with her. If you don't know anyone, there are plenty of lonely mums in rest homes who would enjoy your company for a couple of hours. The visit will make both of your days, and perhaps your lives, a little bit better.

    Although these weather stations are typically seen in homes, they can also be used very easily on farms and fishing boats. Both farmers and fishermen rely on the weather for their business and using up-to-date weather information is quite indispensable. By using the wireless weather stations, it can determine for them when to harvest crops and head back to the shore. Because of the size of the weather station, they can be moved very easily and used wherever necessary for people.

    The wireless weather stations are great for all homes, especially for areas that suffer from extreme weather conditions. The up-to-date, instant weather reports will allow a person to monitor what the weather is doing and if the bad weather is heading in their direction. Extreme weather tends to come very quickly; therefore, any information that is received is helpful.

    The weather stations are very simple to set up and are run by solar panels(太阳能板), ensuring they will work even if there is a power-cut. They are far smaller than those in previous years and give a couple of very simple read-outs for the owner. They are easy to use and fascinating to understand.
