What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

    We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.

    What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.

    He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).

    He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.

    Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

    Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

    These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

     Stephen Hawking is perhaps the world's most famous living physicist. To the public, he's best known as an author of bestsellers such as The Universe in a Nutshell and A Brief History of Time, which have brought an appreciation of theoretical (理论上的)  physics to millions. He is regarded as having one of the brightest minds on the planet. But outstanding astrophysicist (天体物理学家) Stephen Hawking has admitted that he did not learn to read until he was eight years old.

    In a public lecture at the Royal Albert Hall, Professor Hawking also admitted that he was not active in studying while at Oxford University, where he studied physics, and that only the news that he might die young from motor neurone (运动神经元) disease made him focus on his work.

    Professor Hawking said, “My sister Philippa could read by the age of 4 but then she was brighter than me.” He said that he was common at school and was never further than halfway up his class. “My classwork was very untidy, and my handwriting was very bad in the teachers' eyes,” he said. “But my classmates gave me the name Einstein, so probably they saw signs of something better.”

    But he said that it was when doctors told him that he probably only had a few years to live at the age of 21 that he began to focus on his work, which resulted in some of his early achievements. He said, “When you are faced with the possibility of an early death, it makes you realize that life is worth living and there are lots of things you want to do.” Hawking serves as Lucasian Professor of Mathematics at the University of Cambridge, where he continues to contribute to both high-level physics and the popular understanding of our universe.

    There is a popular saying in the English language: “Sticks and stones may break my bones, but words will never hurt me.” Well, that is not true. Unkind words, name-calling or even the so-called “the silent treatment” can hurt children as much as being physically hit, sometimes even more so.

    A recent study of middle school children showed that verbal (言语的) abuse by other children can harm development in the brain. The study was a project of researchers at Harvard Medical School in Massachusetts. Researcher Martin Teicher and his team studied young adults, aged 18 to 25. These young men and women had not ever been treated in a cruel or violent way by their parents.  The researchers asked the young people to rate their childhood exposure to verbal abuse from both parents and other children. Then the researchers performed imaging tests on the brains of the subjects.

    The images showed that the people who reported suffering verbal abuse from peers in middle school had underdeveloped connections between the left and right side of the brain.  The two sides of the brain are connected by a large bundle of connecting fibers called the corpus callosum. This was the area that was underdeveloped.

    The middle school years are a time when these brain connections are developing. So, unkind, hurtful comments from children or adults during this period have the greatest effect. The researchers tested the mental and emotional condition of all the young people in the study.  The tests showed that this same group of people had higher levels of fear, depression, anger and drug abuse than others in the study.

    The researchers published their findings online on the AmericanJournalofPsychiatry's website.

    Parents cannot control what other people say to their children, but they can prepare their children.

    We arrived at the hospital to find Dad was very weak, but his smile was as sure as ever. It was another attack of pneumonia (肺炎). My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from the hospital and look after him. But I longed to be able to let him know that we cared too, even when we weren't with him.

    Then I remembered a family tradition when our children were small. When leaving their grandparents' home after a visit, each child would write a love note to their grandparents. They hid notes in the cereal (麦片) box, under a hairbrush, next to the phone or even in the microwave oven (微波炉). For days, their grandparents would smile as they discovered these signs of our love.

    So as I tidied Dad's kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, “Dad, I put the food in the fridge so it wouldn't spoil.” Some expressed my love, “Dad, I hope you will sleep well in your new bed.” Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, “Dad, if you have found this note, you must be feeling better. We are so glad!”

    Just like his medicines strengthened him physically, these “emotional vitamins” would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, “Pretty good. I just found your note under my pillow upstairs!”

    This is a family story my father told me about his mother, my grandmother.

In 1949, my father had just returned home from the war. On every American highway you could see soldiers in uniform hitchhiking home to their families, as was the custom at that time in America.

    Sadly, the thrill of his reunion with his family was soon overshadowed. My grandmother became very ill and had to be hospitalized. It was her kidneys, and the doctors told my father that she needed a blood transfusion immediately or she would not live through the night. The problem was that grandmother's blood type was AB-, a very rare type even today, but even harder to get then because there were no blood banks or air flights to ship blood. All the family members were typed, but not one member was a match. So the doctors gave the family no hope; my grandmother was dying.

    My father left the hospital in tears to gather up all the family members, so that everyone would get a chance to tell grandmother goodbye. As my father was driving down the highway, he passed a soldier in uniform hitchhiking home to his family. Deep in grief, my father had no inclination at that moment to do a good deed. Yet it was almost as if something outside himself pulled him to a stop, and he waited as the stranger climbed into the car.

    My father was too upset to even ask the soldier his name, but the soldier noticed my father's tears right away and inquired about them. Through his tears, my father told this total stranger that his mother was lying in a hospital dying because the doctors had been unable to locate her blood type, AB-, and if they did not do it before nightfall, she would surely die.

    It got very quiet in the car. Then this unidentified soldier extended his hand out to my father, palm up. Resting in the palm of his hand were the dog tags from around his neck. The blood type on the tags was AB-. The soldier told my father to turn the car around and get him to the hospital.

    My grandmother lived until 1996, 47 years later, and to this day no one in our family knows the soldier's name. But he is always remembered by us.
