At the end of every year, Time picks the best 25 inventions that are “making the world better and smarter”. Here we have picked three of this year's inventions that could be a part of your life in the near future.

The levitating(悬浮的) lightbulb

    This special lightbulb was invented by US artist and scientist Simon Morris. He got the idea of making a lightbulb float from hoverboards(悬浮滑板)，which he used to dream of having as a kid.

    But the floating is not the most amazing part. The rejection force between the opposite ends of the magnets(磁铁)，which were put in the bottom of the bulb and in the wooden base, does the job. What's new here is a technology called induction (电磁感应). It allows the lightbulb to get power from the base even they are not in contact.

Shoes that tie themselves

    They're not what you think-shoelaces that tie themselves in the way we tie them. Instead, the new shoes have small motors that control their laces. When you step in them, your feet will hit a sensor（传感器）in the shoes and the motor will automatically tighten the laces.

    But the shoes weren't just designed for lazy people's needs. They could actually give athletes an advantage during competition. They are also useful for people who cannot move their arms or fingers easily.

The no-touch thermometer

    Taking your body temperature usually means putting a thermometer (体温计) in your armpits (腋窝) and staying still for minutes. It may be easy for you, but it's an impossible task for little kids.

    Now, with the new thermometer, users can simply put it 2.5 centimeters from a patient's forechead and press the button, and it can get the reading in two seconds.

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子), but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

    Onboard the Clips device, it uses machine learning algorithms ( 计 算 程 序 ) to help capture scenes. Those algorithms include face recognition. "Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces," said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved "training it to know what happiness looks like". The Google team also trained it to recognize what not to shoot—like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    "This product is only possible because of the way that silicon has advanced," Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    There is a common belief among parents that schools are no longer interested in spelling. No school I have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite different ideas about how to teach it, or how much priority(优先) it must be given over general language development and writing ability. The problem is, how to encourage a child to express himself freely in writing without holding him back with spelling.

    If spelling becomes the only point of his teacher's interest, clearly a bright child will be likely to "play safe". He will write only words within his spelling range(范围). That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.

    I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling mistakes." It may have been a sharp criticism(批评) of the pupils technical abilities in writing, but it was also a sad thing for the teacher who had omitted to read the composition, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more hope to seek improvement.

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name — phubbers（低头族）.

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie（自拍照）in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

    Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. "Constantly bending your head to check your cell phone could damage your neck," Guangming Daily quoted doctors as saying. "the neck is like a rope that breaks after long-term stretching." Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    When Rebecca Saxon was diagnosed with cancer at the young age of 27, she thought her life was over. But in her darkest hour, inspiration struck and she found a way of turning her misfortune into advantage.

    Following her cancer treatment, Rebecca launched a successful business "Something Blue Bridal Shoes"—a unique range of wedding footwear, which came out of the fashion pictures she drew while recovering in her hospital bed.

    Rebecca, from London, says, "I started designing wedding shoes with blue soles (鞋底) when I was halfway through my cancer treatment. I had a hit when I was diagnosed with cancer but I decided that I was going to pick myself up and fight this cancer. The pictures were my release and the way I got through the many hours spent in a hospital room. I had no idea what was going to happen to me, but I knew I had to be positive if I was going to overcome this treatment. I told myself this was not going to be the end for me. I decided to fight with my negative feelings and start drawing."

    Rebecca had always loved fashion since she was younger. Several of her friends were getting married at the time when she was ill. "So at first, I would be drawing designs for wedding dresses and other clothes. But then I started drawing wedding footwear—designing shoes with blue soles which were very comfortable too. I thought it would be a lovely way of combining the 'something old, something new, something borrowed, something blue' tradition. Drawing really helped me deal with my treatment," said the brave girl.

    With the encouragement of her boyfriend, she turned her dreams into her reality and set up "Something Blue Bridal Shoes". Each beautiful shoe has a blue sole, combining the age-old tradition of what a bride should wear at her wedding for good luck.
