Salvador Dali (1904-1989) was one of the most popular modern artists. The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings, sculptures, drawings and more. Among the works and masterworks on exhibition the visitor will find the best pieces, most importantly The Persistence of Memory. There is also L'Enigme sans Fin from 1938, works on paper, objects, and projects for stage and screen and selected parts from television programmes reflecting the artist's showman qualities.

    The visitor will enter the World of Dali through an egg and is met with the beginning, the world of birth. The exhibition follows a path of time and subject with the visitor exiting through the brain.

    The exhibition shows how Dali draws the viewer between two infinities (无限). “From the infinity small to the infinity large, contraction and expansion coming in and out of focus: amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,” explains the Pompidou Centre.

    The fine selection of the major works was done in close collaboration (合作) with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg.

    In the latter part of the 20th century, child labor remains a serious problem in many parts of the world. Studies carried out in 1979, the International Year of the Children, showed that more than 50 million children below the age of 15 were working in various jobs often under dangerous conditions. Many of these children live in underdeveloped countries in Latin America, Africa, and Asia. Their living conditions are crude and their chances for education small. The poor income they bring in, however, is necessary for the survival of their families. Frequently, these families lack the basic necessities of life—adequate food, decent（得体的、合适的）clothing and shelter, and even water for bathing.

    In some countries industrialization has created working conditions for children that are comparable to the worst features of the 19th-century factories and mines. In India, for example, some 20,000 children work 16-hour days in match factories.

    Child-labor problems are not, of course, limited to developing nations. They occur wherever poverty exists in Europe and the United States. The most important efforts to eliminate（根除）child-labor abuses throughout the world come from the International Labor Organization (ILO), founded in 1919 and now a special agency of the United Nations. The organization has introduced several child-labor conventions（规定）among its members, including a minimum（最低）age of 16 years for admission to all work, a higher minimum age of specific types of employment, compulsory（强制的）medical examinations, and It depends on voluntary obedience（服从）of member nations.

    When it comes to mental illness, many people often find it tough to get the help they need. This is especially true for young students making the transition(过渡) to college life.

    “Sometimes, students don't realize how hard it is to adjust to college,” said Laura Smith, associate dean of students at the University of Texas at Dallas. “You're not the big fish in your classes anymore; you have all kinds of personal stress; you're away from home. Dealing with these things is not easy.”

    Students who are going through these problems sometimes want to reach out. But if students don't feel comfortable seeking help, many feel that it's the responsibility of their university to help them.

    “I really wish that there was more importance placed on how counseling(咨询) centers help students,” said Comnie Trinh. “Counseling services are just as important as academics and sports.”

    Trinh, 27, graduated from Texas Woman's University in 2015. During college, she hosted various workshops on how to handle mental health conditions. Trinh used her own story to connect with students who might be facing similar problems. High academic pressures, cultural differences as an Asian American and stressful social situations stood out as some of the most common causes of Trinh's anxiety.

    It was only after years of personal problems that she could admit that reaching out isn't a sign of weakness.

    ”If you feel you can't connect with other people around you, you should address the issue without shame,” Trinh said. “You'll find that there are a lot of people out there who sincerely want to help you.”

    The month of March was a milestone for supporters of renewable energy in the U.S. For the first time, wind and solar power accounted for more than 10% of the country's electricity—up from less than 1% at the turn of the century. And total wind and solar power-plant capacity(发电量) is expected to grow more than 30% over the course of this year and next, according to the Energy Information Administration.

    Such forecasts have led many scientists and policymakers to think that moving a large part of the nation's power supply to renewable sources—as cities from Miami Beach to Salt Lake City have promised to do—may not be as far-fetched as once thought. But like any debate, there are dissenters, including those inside the federal government. Their argument is that the nation demands an uninterrupted supply of electricity and cannot count on sun, wind and natural gas to provide it. “You need solid hydrocarbons(固体碳氢化合物) on-site for rising peak demand,” Environmental Protection Agency administrator Scott Pruitt said on Fox Business in May, referring to the importance of coal as a power source.

    Many experts say the government's concern fails to account for how the power grid(电网) has improved in recent decades. Utility companies(公共事业公司) have developed innovative ways to move electricity from place to place to account for variation in weather. Battery technology can store power for use when renewable sources cannot operate, meaning solar power can be used on days when the sun doesn't shine. And the nation's vast supply of natural gas can be turned into usable energy with the flick of a switch.

    “I don't think 5 or 10 years ago I'd be comfortable telling you we could not sacrifice reliability when we're going to have 35% of our energy come from wind,” said Ben Fowke, CEO of the utility company Xcel Energy, at a recent conference. “I'm telling you, I'm very comfortable with that today.”

    Indeed, many parts of the country are already close to that reality. In some regions, like Iowa and Kansas, renewable energy supplies more than 25% of the electricity. The market has shifted so far in favor of natural gas and renewable energy that even the most concerted federal effort is unlikely to stop its growth. Any attempt to slow the growth of wind and solar will face strong pushback. “If anyone wants to do away with it,” Republican Senator Chuck Grassley told Yahoo News of the federal government's potential cuts to wind energy, “he'll do it over my dead body.”

    But the federal government could slow the acceleration—and with billions of dollars in private and public investments at risk, the pace of change matters. Decisions made today will shape the future of the nation's energy grid for decades to come.

    Barbara McCintock was one of the most important scientists of the twentieth century. She made important discoveries about genes(基因) and chromosomes (染色体).

    Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to Brooklyn area of new York City in 1908.Barbara was an active child with interests in sports and music. She also developed an interest in science.

    She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.

    Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed a master's degree in 1925. Two years later, she finished all her requirements for a doctorate degree.

    McCintock stayed at Cornell after she completed her education. She taught students botany. The 1930s were not a good time to be a young scientist in the United States. The country was in the middle of the great economic Depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.

    An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started in a temporary (临时的) job with the genetics department. A short time later, she accepted a permanent (永久的) position with the laboratory. This gave her the freedom to continue her research without having to teach or repeatedly ask for financial aid.

    By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.

    We talk a lot in the U.S. about success. Success is the dream and the end point. And not by coincidence the idea that hard work leads to personal success is as American as apple pie.

    But the reality is that sometimes we fail. And sometimes things, through no fault of our own, don't go our way. We're faced with a life-changing diagnosis (诊断), the passing of a loved one or job loss. We don't, as a society, have as much to say here.

    I think uncertainty does us all harm. We'd feel better equipped to deal with uncertainty if we talked about it more. I had so fully bought into the belief that with enough effort, I could control what happened in my life. I actually caught myself thinking I could "work my way out" of my cancer. As it turns out, cancer doesn't really care about one's work.

    We might also make wiser decisions — this isn't just a feel-good exercise. For example, technology and medicine have progressed to the point that many patients are living longer than they would have even a decade ago. These are achievements worth celebrating. And yet I wonder if the focus on success is sometimes misguided here as well. If it is one reason why we tend to pursue expensive end-of-life treatments, they often accomplish little other than to make a patient's final days painful and frightening. The fact is that, when asked, many patients would rather focus on living meaningfully in their final days.

    My hope here is to make a case for thinking about meaning, in the same way we think about pursuing success. In that spirit, I've asked several people, each of whom has met misfortune, how they find meaning in their lives. The diversity in their responses reflects the fact that there are no right or wrong answers here. We each can find meaning in different things.
