Dear Mr. Rupp,

    The day I met you was the first day of high school. We liked each other immediately. You gave me a lot of advice over the next four years, like how I should get my ass to Berkeley where I belonged. I'm still there, by the way. I wish you were still around, too.

    I remember your laugh, which would start with a rough guffaw(狂笑) and end with a hacking smoker's cough that would make even the most rebellious (叛逆的) teenager decide to lay off the cigarettes. I remember the way you didn't lower your standards, yet still refused to give up on us. You were tough on us, and we were tough on you. Love is tough sometimes.

    The last time I wrote you a letter, it was 2005—four years after I graduated. I had just become a teacher, like you, and it had given me a new appreciation for the work you did with countless high school students over the years.

    It's hard to say what I'll miss the most about you. There are simply too many memories to sort through those four years, and it hurts to think you'll never read this letter. I want to believe that you knew how much you meant to your family, your students, your community, and your colleagues, but that would be a lot of realization to handle, even for you.

    You changed the lives of everyone around you. Even now, you are reminding me to cherish life and its brevity and beauty, and to tell the people I love how much they mean to me before it is too late.

    Dear teacher, dear mentor, and dear friend—I miss you and all that is about you. God bless you in Heaven.

To infinity and beyond,

Teresea

    A team of engineers at Harvard University in trying to create the first robotic fly. Designed to do what a fly does naturally, the tiny is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "The added difficulty with a project like this is that actually none of its components is off the shelf and so we have to develop them all on our own' said Robert Wood, a Harvard engineering professor.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies (相互依赖）on the individual components, each of which individually has to perform well, but then has to be matched well to everything it d connected to," said Wood.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications." You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animal, but using these robots instead" he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis."

    The boy sat on his chair, with his hand above the keyboard. He thought about what to write.

    He recalled that the competition deadline was merely a week away. But he still had not even started on his piece. He looked at the brochure again." WRITING COMPETITION!" the title read. His mom had encouraged him to enter the writing competition, and now he was taking it on as his personal task for the holidays.

    As the boy reflected on his previous writing efforts, he realized how hopeless his task of winning was. Every story he ever wrote was based on other stories. He had little imagination, and unfortunately, imagination was the key to writing.

    Suddenly, he had a brainwave. This time, he came up with an original and imaginative story.

    The words shot towards him like a storm of leaves. Words were coming easily, flowing through him, faster than he could type. He typed faster than he ever had before. He continued to type, amazed at how easy writing this story was. The boy could not stop writing. He looked at the word count and saw the number" 248" staring right back at him. He was not even halfway yet.

    Then he heard the call of his mother saying time for bed. He continued writing the piece, ignoring her. He had to make up for the time he had lost thinking about a topic to write.

    Finally, he finished. The word count now read"498".

    "Perfect," he thought," just under the word limit." He knew this was the story that would win.

    He went onto Google and searched for the competition. He found the page but there was no "Enter" button.

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing 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.

Smart and highly sensitive （灵敏的）, a new soft sensor developed by UBC (University of British Columbia) and Honda researchers opens the door to a wide range of applications in robotics and prosthetics （假肢）.

When applied to the surface of prosthetic or robotic arms, the sensor skin provides touch sensitivity and flexibility, making it possible for difficult tasks to be completed by machines, such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin. which helps make human interactions safer and more lifelike.

"Our sensor uses weak electric fields to sense objects, even at a distance, much as touchscreens do. But unlike touchscreens, this sensor is soft and can detect forces into and along its surface," explained Dr. John Madden, senior study author and a professor of electrical and computer engineering who leads the Advanced Materials and Process Engineering Laboratory at UBC.

The UBC team developed the technology in cooperation with Frontier Robotics, Honda's research institute. Honda has been innovating in humanoid robotics since the 1980s, and developed the well-known ASIMO (Advanced Step in Innovative Mobility) robot. It has also developed devices to assist walking and the emerging Honda Avatar Robot.

"Dr. Madden's lab has significant expertise in flexible sensors and we're happy to cooperate with this team in developing touch sensors that can be applied to robots," said Mr. Ishizaki Ryusuke, one of the study's lead authors and chief engineer at Frontier Robotics.

Dr. Madden said, "Human skin has a hundred times more sensing points on a fingertip than our technology does, making it easier to light a match or sew. As sensors continue to develop to be more skin-like, and can also detect temperature and even damage, there is a need for robots to be smarter about which sensors to pay attention to and how to respond. Developments in sensors and artificial intelligence will need to go hand in hand."
