Steven Spielberg never fails to blow us away with his imagination.

    The US director's latest film Ready Player One, which was released in Chinese mainland cinemas on March 30, is a story set in the year 2045, when people escape their hopeless everyday lives by putting on a VR mask and entering a virtual (虚拟的) world named Oasis. This fantasy land is filled with characters and settings right out of classic films and videogames like The Shining and Overwatch. It's a feast both for the eyes and mind. And at the age of 71, Spielberg is still “at the top of his game”, wrote reporter Rafer Guzman on Newsday.

    Indeed, Spielberg has always been a gamer himself or rather a game changer. When his thriller Jaws came out in 1975, it struck a chord (引起共鸣) with audiences all over the world and kept people from going swimming for fear. The film was also the first example of what we now know as summer blockbusters.

    “Jaws invented that form of pleasurable entertainment, wrote Stephen Marche on Esquire. It also turned sharks, in the popular imagination, from fish into monsters.”

    And again, in his 1982 film E. T. the Extra-Terrestrial Spielberg challenged people's beliefs that aliens are something to be feared by telling a story about a loving friendship between a space creature and a little boy. “Spielberg redefined popular sci-fi”, wrote Marc Lee on The Telegraph. “Extra-terrestrials no longer had to be a threat to humanity: the universe, he was saying, is also full of awe and wonder.”

    Now comes Ready Player One. When Wade Watts, the film's teenage protagonist (主角), finally prevents Oasis from falling into the wrong hands, he's given ownership of the virtual world by its late designer James Halliday. But Watts makes a decision that he hopes will make people want to appreciate their real lives, instead of spending all their free time escaping reality in Oasis, which is a real-life message that Spielberg is trying to deliver to the audience.

    Home from the Navy, I started school at Greenville College in my hometown of Illinois. I'd been out of high school for four years, but my high school headmaster, Mr. Gardner, invited me to a Valentine's Day dance party at school. The thought of seeing my former teachers was exciting. So I agreed.

    When Friday came, I cleaned up, dressed up and drove to the high school gym. I chatted with my teachers and approached Mr. Gardner to thank him before leaving. Just then, the band started playing and a young girl stood up to sing. One look at and I was crazy—I had never seen such a beautiful girl!

    I asked Mr. Gardner who she was, and he answered, “That's Marilyn Riley, Cut Riley's daughter.” I was shocked to say the least. They lived just around the corner from me. I walked across the gym floor to introduce myself, “Hi, I'm Jack Joseph.”

    “I know who you are,” was her not-too-friendly response.

    “Would you like to dance?” I asked. “No! I'm working,” she shot back.

    “Can I call you next week for a movie date?” I asked. “No,” was her response.

    For the next month I phoned, trying to set up a date. She always had the same answer: No. then one rainy afternoon in March as I was driving home after basketball practice, I saw Marilyn, walking with no umbrella, no raincoat, no hat. I pulled alongside her and asked if she needed a ride, half expecting her to say no. instead, she stepped over the roadside and sat down on the seat next to me. It was only a few blocks to her house, but after pulling into her driveway we talked for 45minutes. It was magic from then on.

    Heat has been used to control hair for hundreds of years. But how much is too much? If you have ever opened a very hot oven, you know that heat can burn your eyebrows off your face very quickly. A scientist from Purdue University in Indiana is trying to find a scientific answer on how hot is too hot when it comes to your hair.

    Many women and some men are very particular about their hair. Some people who have naturally curly hair prefer to have it straightened. Others with straight hair want to have curls. Tahira Reid is one of those people. As an African-American woman, she is familiar with the challenges of maintaining (保养)curly hair.

    Tahira Reid and other researchers at Purdue University are studying how heat treatment interacts with different types of hair and how to prevent damage. Amy Marconnet is an assistant professor. She says the team is seeing how heat and temperature relate to their research.

    In a Purdue University's lab, team members designed a hair straightener tool —a flat iron with temperature control. They attached it to a robotic arm that moved over pieces of hair. They controlled the temperature while the device straightened hair.

    What did they find? Their study found that the heat weakens or breaks a protein called keratin, responsible for the hair's shape, and temporarily changes it. But nobody knows exactly what level can make the heat actually cause forever change. Researchers say early results are a bit inconclusive.

    It turns out that everyone's hair is different and there's no exact temperature where hair straightening becomes hair damage. Ms Reid says they will continue their research in the hope of finding what works best without damaging hair.

    I must have looked deep in thought, or as deep in thought as an 11-year-old man can, when my grandmother glanced up from her weeding to ask, “You have something on your mind, don't you?”

    “Yes, I was thinking that someday I want to be an Olympic speed skating champion like my hero, Eric Haiden, I want to be a doctor like my parents and I want to help children in Africa.”

    I immediately knew I had confided in the right person when a knowing smile broke across her face. “Johann, of course! You can do anything you want to do!” she said simply. And with my grandmother's support, I set out to pursue my passions.

    14 years later, I was well ready to take hold of my first dream: becoming an Olympic champion. The Olympics in 1994 were in my home country, Norway. As I entered the Olympic stadium, I wasn't the best athlete, and many had doubts about my ability to perform well. But I had something special working for me. I had a woman in the first row who believed in me following my passions just as much as I did. For the first time ever, my grandmother was going to see me skate.

    It happened. Breaking a world record, I won the gold.

    As I stood on the podium(领奖台) that I had dreamed about my entire life, a curious question popped into my head. Why me? Why did I win, given all the other incredible competitors out there? The reason had to be more than a grandmother who shared a belief in her grandson's dream. The question led me to only one answer: because I wanted to make a difference in the world, and with all the media attention on my success, I could.

    I immediately knew what that difference had to be: hope in the lives of the children in Africa. Six months earlier, I'd been invited to Eritrea as an ambassador for Olympic Aid.

    Everybody seeks happiness in the world. We will be really happy when we get a new car or a big house or get married... The thing is, if we are continually searching for happiness in the outside world, we will be very disappointed. It seems as if we are forever chasing it and it is always just one step away.

    Happiness is a short state of mind, just like the state of sadness or joy or anger. It would not be possible for us to be in a happy state 24 hours a day. If you think that sounds laughable, think about being at a funeral when everyone is mourning. Would it feel right to go about with a huge smile on your face?

    What we go through in our lives helps us grow and understand the value of happiness. We need to be able to respond in all manner of ways according to what we are dealing with at any given time. All emotions and states are part of the life.

    Happiness can be found in reaching out and being in relationship with people. Though time or money may be lost in helping others, these will become our happy memories. Happiness is a dance with whatever in front of you. It is a deep connection to everything around you. It does not come from expecting others to bring you joy but from how you can create joy for others.

    If you want to experience happiness more often, see what you can do to put a smile on someone else's face each day and notice how much happier you feel when you have achieved that. Happiness is not to be found in material possessions. It is freely available to everyone at any time. All that is required to experience happiness is that you place your focus on moments in your life that make you smile.
