The truth about left-handed peopleAbout 90% of people in the world today are right-handed. The other 10% are left-handed, including Obama, the president of the US. Every day, left-handed folks quietly face problems. It could be something as simple as driving a car or using a can opener.Why are so few of us left-handed? One theory is that handedness (hand preference) could be a result of genetics. Scientists say that there are two genes(基因) associated with handedness. One is the D gene. It is more frequent in the population and promotes（促成）right-handed preference. The other is the C gene. It has the ability to promote a preference for either hand. When the C gene is present, there is a 50% chance that a person could be right-or left-handed.Another theory has to do with human brains, which are made up of two halves. If the left hand is more powerful, then one is most likely right-handed. But with left handers, it is more complicated. Seventy percent of them are also left-brain dominant（占优势的）. The other 30% have right-side dominant brains.During the 18thand 19th centuries, left-handedness was considered a disability. But not all of the myths about left-handers are bad. One myth suggests that they are more creative and smarter than the right-handers. So far scientific research has yet to find any truth to these claims. In fact, a 2013 survey out of New Zealand found that left-handers and right-handers were the same.Life might be a little more complicated for left-handers when it comes to cutting a piece of paper or opening a bottle of wine. However, it seems to be a good sign if you are trying to make it to the white house.Some scientists believe that handedness is decided by genes.

A twentieth-century womanMarya Skodowska was born on November 7, 1867, in Poland. Marya’s father wanted his five children to go to college, but the family was poor. In fact, Marya worked for six years to make money so her elder sister Bronya could study medicine in Paris. When Bronya finished medical school in 1891, 23-year-old Marya went to Paris to begin her own study.In July 1893, Marie passed her physics exam first in her class. At this time, she met Pierre curie, a young scientist. Marie and Pierre found that they had much in common. They both believed that science was the most important part of their lives. They didn’t care about money or about being comfortable. They fell in love, and were married on July 26, 1895. Marie and Pierre were very happy. They discussed their work as well as the most recent scientific events, such as the discovery of X rays. Marie was interested in this research and began to look for unknown elements that had such rays. Pierre stopped his own research in order to help Marie in her work. He realized that she was about to make an important discovery.In 1898, they discovered two new elements that gave off X rays. In those days, no one knew that such materials were dangerous. They did not know that working with these materials caused their illness, and they kept working. Finally, in 1902, they proved that radium (镭) is real.On June 25, 1903, Madame became the first woman to receive a doctor of science degree from the Sorbonne. Then she received an even greater award. In 1903, Marie and Pierre and Henri were awarded the Nobel Prize in physics.1 Marya went to Paris to begin her own study when she finished medical school.
