The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    We know the famous ones — the Thomas Edisons and the Alexander Graham Bells — but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper（雨刮器）? Shouldn't we know who they are?

    Joan Mclean think so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she's developed a course on the topic. In addition to learning “who” invented “what”, however, Mclean also likes her students to learn the answers to the “why” and “how” questions. According to Mclean, “When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try.”

    Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of Mclean' statement. “If I had not heard the story of the windshield wiper's invention,” said Tommy Lee, a senior physics major, “I never would have dreamed of turning my bad experience during a rainstorm into something so constructive.” Lee is currently negociating to sell his patent to an umbrella producer.

    So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn't be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever（操作杆）on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.

    Today we benefit from countless inventions and innovations. It's hard to imagine driving without Garrett A. Morgan's traffic light. It's equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?

    For a long time being happy was considered something that just happened, and there was nothing special about it. Now we know that getting along with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything from our friends. Another way is to look for good points, not bad ones in other people. It is surprising how successful this treasure hunt can be.

    You don't have to be spineless (软弱的) in order to be popular. In fact, you will be liked and respected if you are not afraid to stand up for your rights. But do it politely and pleasantly. Being friendly and polite to your group, to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character.

    You can not expect to be perfect, and so you must learn not to be unhappy when you make mistakes. Everyone makes mistakes, and no one is to be blamed (责备) unless he refuses to learn from them. Many young people become discouraged when they know in themselves qualities (品格) that they do not like—selfishness, laziness, and other unpleasant qualities. Just remember that we all have some of these faults and have to fight against them.

    At the same time, it is important to remember that, while you are probably no worse than others, the best way to be happy is to think yourself above other people. When something is wrong, it is good sense to try to make it right. Perhaps you don't like a teacher or a classmate. Try to see why, and look at yourself, too. To be sure that you are not doing anything to make that person dislike you. Some day, things may turn out all right, then you will have to learn to get along the best with situation, without thinking too much about it. Worrying never helps in a situation you can't change.

    Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.

    No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.

    There's more good news for people, if they have friends. These people live longer than those people if those don't have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares, if someone cares about you, you take better care of yourself.

    Picasso Blue and Rose' at the Musée d'Orsay in Paris

    Through Jan.6.2019

    In its first major partnership with the Musée National Picasso﹣Paris, the Mus6e d'Orsay presents a show about Pablo Picasso's "Blue and Rose periods. "Some iconic（标志性的）Picasso works from this period in 1900～1906 ﹣﹣which experts consider a key point in his career—will make their first appearance in France for this exhibit. The show features over 300 works, including 80 paintings, 150 drawings, sculptures and prints, alongside photographs and letters from this time in the artist's life.

    'Hodler Parallelism' at the Kunstmuseum Bern in Switzerland

    Through Jan. 13, 2019

    This year marks a century since the death of one of Switzerland's most famous painters: Ferdinand Hodler. To honor his great achievements, the Kunstmuseum Bem and Geneva's Museum of Art and History have joined forces for a show focused on his theory of parallelism. Hodler considered parallelism a key principle of his work and employed it through the use of repetition, patterns, symmetry（对称） and mirror images, The show features 99 of Holder' s works.

    Claude Monet' at the Albertina in Vienna

    Through Jan. 6, 2019

    For the first time in over 20 years, a large﹣scale Monet exhibit can be seen in Austria. The Alhertina has gathered 100 paintings from more than 40 international museums and private collections, including the Musée d'Orsay in Paris, the Museum of Fine Arts in Boston, the National Gallery in London, the National Museum of Western Art in Tokyo, and the Pushkin Museum of Fine Arts in Moscow.  Highlights include the works: "On the Boat," "Boulevard des Capucines," "Grainstack in Sunlight," and "The Japanese Bridge."

    Donna Strickland is a professor in the Department of Physics and Astronomy. Professor Strickland is one of the recipients(受领者) of the Nobel Prize in Physics 2018 with Gérard Mourou, her PhD supervisor at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York state. Together they paved the way toward the most intense laser pulses ever created.

    Professor Donna Strickland is only the third woman ever to have won a Nobel Prize in physics. She and her fellow winners were honored for what the Nobel Committee called ground-breaking inventions in laser physics. Professor Strickland devised a way to use lasers as very precise drilling or cutting tools. Millions of eye operations are performed every year with these sharpest of laser beams.

    "How surprising do you think it is that you're the third woman to win this prize?"

"Well, that is surprising, isn't it? I think that's the story of Maria that people want to talk about — that why should it take 60 years? There are so many women out there doing fantastic research, so why does it take so long to get recognized?"

    Physics still has one of the largest gender gaps in science. One recent study concluded that at the current rates it would be more than two centuries until there were equal numbers of senior male and female researchers in the field.

    The last woman to win a physics Nobel was German-born Maria Goeppert-Mayer for her discoveries about the nuclei of atoms. Before that it was Marie Curie, who shared the 1903 prize with her husband, Pierre. This year's winners hope that breaking this half century hiatus will mean the focus in future will be on the research, rather than the gender of the researcher.
