It is common knowledge that music can have a powerful effect on our emotions. In fact, since 1930s, music therapists have relied on music to soothe patients and help control pain. Now psychologists are confirming that music can also help relieve depression and improve concentration. For instance, in a recent study, 15 surgeons were given some highly stressed math problems to solve. They were divided into three groups: one worked in silence, and in another, the surgeons listened to music of their choice on headphones; the third listened to classic music chosen by the researchers. The results of the study ma y surprise you. The doctors who got to choose their music experienced less stress and scored better than the others. One possible explanation is that listening to music you like stimulates the Alfa-wave in the brain, increases the heart rate and expands the breathing. That helps to reduce stress and sharpen concentration. Other research suggests a second relation between the music and the brain: by examining the students' blood after they listening to a variety of classic music collections, the researchers found that some students showed a large increase in endorphin, a natural pain reliever, this supports what music therapists have known for years: Music can help rejuvenate or soothe the patient.

One important thing about art movements is that their popularity can be affected by social conditions , which are themselves often affected by historical events. As an example, look at what happened in the United States early in the 20th century, around the time of the great depression, the art movement known as the Regionalism had begun in the United States even before the depression occurred. But it really flourished in the 1930s, during the depression years. Why? Well, many artists who had been living in big cities were forced by the economic crisis to leave those big cities and move back to their small I towns in rural America. Some of these artists came to truly embrace the life in small towns and to eject City life in so called "sophisticated society" . These artists or specifically certain painters really built regionalist movement. They created things in every day life in small towns or farming areas. And t heir style was not all-neutral, really big glorified or romanticized country life, showing it stable, whole some, and embodying important American traditions. And this style became very popular, in part because of the economic conditions of the time. You see, the Depression had caused many Americans to begin to doubt their society. But regionalism artists painted scenes that glorified American values, scenes that many Americans could easily identify with. So the movement helped strengthen people' fait h in their country, faith that had weakened as the result of the depression. But in the 1940s, before an d after the Second World War, American culture began to take on a much more international spirit, and Regionalism, with its focus on small town life, well, it lost a lot of popularity, as American society c hanged once again.

Hallo, everybody, I am here, because I visited caves all over North America. Since you are going to study cave formations, Dr. Bow asked me to come and share some of my experiences with you. In additional to describing some of the technical aspects of the caves, I would convey the sense of adventure that cavers share. Recently, I visited the La Chagire cave in New Mexico, my dream has always been to discover a new passage way. I had a chance here, because La Chagire is so large that discoveries are frequently made there. The cave itself was not even discovered until 1986. However, people in that area had figured that there must be a cave nearby, because of the strong wind that blew from behind the huge rock that covered the entrance. Enormous amounts of air enter and exit the cave in order to maintain balance of the pressure with the side air. When I climbed into the cave, I had to fight 45 mile per hour winds. After all that effort, I had to be extremely careful maintaining my energy level. People who are tired tend to be careless, and may be more concerned about getting out of the cave than taking care of it. There are formations in La Chagire that look like ocean waves, Christmas trees and other stuff no one has ever seen before. Caves are normally created by carbonic acid that trickles down from above, but this cave sculpted out by very powerful sulfuric acid that wells up from below.
