“The 13th of June,1325,I left Tangier,my birthplace,with the intention of making the pilgrimage(朝圣)to Mecca ...to leave all my friends,to abandon my home as birds abandon their nests.” So begins an old manuscript in a library in Paris—the travel diary of Ibn Battuta.

Almost two centuries before Columbus,this young Moroccan set off for Mecca,returning home three decades later as one of history’s great travelers.Driven by curiosity,he journeyed to remote corners of the Islamic world,traveling through 44 modern countries,three times as far as Marco Polo.Little celebrated in the West,his name is well known among Arabs.In his hometown of Tangier,a square,a hotel,a cafe,a ferry boat,and even a hamburger are named after him.

Ibn Battuta stayed in Mecca as a student for several years,but the urge to travel soon took over.In one adventure,he traveled to India seeking profitable employment with the sultan—the Muslim ruler of Delhi.On the way,he described his group being attacked in the open country by 80 men on foot,and two horsemen: “… I was hit by an arrow and my horse by another,but God in his grace preserved me ...” In Delhi,the sultan gave him the position of judge,based on his previous study at Mecca.But the sultan had an unpredictable character,and Ibn Battuta looked for an opportunity to leave.When the sultan offered to finance a trip to China,he agreed.Ibn Battuta set off in three ships,but misfortune struck while he was still on the shore.A sudden storm grounded and broke up two ships,scattering (散播)treasure and drowning many people and horses.As he watched,the third ship,with all his belongings and slaves—one carrying his child—was carried out to sea and never heard from again.

After a lifetime of amazing adventures,Ibn Battuta was finally ordered by the Sultan of Morocco to return home to share his wisdom with the world.Fortunately,he agreed and wrote a book that has been translated into numerous languages,allowing people everywhere to read about his unparalleled journeys.

In high school I had a math teacher, Mrs.Davies, who took her job seriously and expected her students to put forth the same degree of commitment. Strict but fair, she held our attention with her time-proven approach. One of her was for students who were more advanced academically. I chose to it and soon realized that the course was a bit over my head. I with the complex problems that others seemed to learn without much effort

One Friday we were tested our ability to use a theorem(定理) that no one in the class thoroughly understood. The teacher would our papers based on our ability to progress through the problem which easily filled two pages of formulaic notations(公式符号). I was absolutely . Finally, I didn't use the required theorem. Instead, I decided to use more familiar theorems to arrive at an . I knew I had failed because I hadn't done the 43 assignment.l became resigned to my fate.

Our test papers were back the following Monday. Everyone received a "C" except for me To my surprise, I received an "A". I that there must be a mistake. I watched as the teacher approached my desk, smiled, and asked for my test back. She then went back to copy my work onto the blackboard, the class how I had arrived at the correct answer. "Mathematics is meant to be a creative tool, pushing our minds to a rewarding answer," she said with confidence. I didn't use the required theorem, she seemed genuinely proud of how I'd worked through the problem. The class saw her fold my test paper and put it into her textbook. She announced that it would be with future classes

My teacher would have been justified in giving me a grade. Instead, she used the to deeply influence a student who often struggled. And after forty years, I still cherish the . It helped change my self-image. I up to a broad boundary of possibilities which has made my life an adventure. She understood that teaching went beyond strict demands and could be used to .Thank you, Mrs.Davies.

It is easy to lose patience with science today. The questions are pressing: How dangerous is air pollution? What about low-level radiation? When will that horrible earthquake strike California? And why can't we predict weather better? But the evidence is often described as "uncertain", forcing scientists to base their points of view almost as much on intuition(直觉)as on science.

When historians and philosophers of science listen to these questions, some conclude that science may not be able to solve all these problems any time soon. The unknowns can grow into riddles that are impossible to solve. Because of the unstable and changing state of the earth's atmosphere, for example, scientists have struggled for centuries to predict the weather with precision(精确) but failed.

The case is different for scientists of astronomy. For example, they think that the gravitational force of a nearby space vehicle, though tiny, is able to change the path of a much larger planet if the vehicle spends enough time close to it. With the aid of Newton's laws of gravitational attraction, ground controllers can predict the path of a planetary probe (探测仪)-or satellite-with incredible accuracy. They do this by calculating the gravitational force from each of the passing planets until the probe speeds beyond the edge of the solar system.A much more difficult task is to calculate what happens when two or three times of such force pull on the probe at the same time. Such procedures can, of course, be very difficult, but for experiments, they are effective.

This range of questions-from simple problems to those impossibly complex-has resulted in nicknames for various fields of study: "soft" sciences and " hard " sciences.“Soft” sciences admit a great degree of uncertainty. Academicians tend to judge fields such as sociology, psychology, and political science as “soft” because they are assumed to be understandable, of unnecessary mathematical accuracy, and concerned with everyday affairs such as interpersonal relationships. However, "hard" sciences, such as astronomy and chemistry, are said to offer precise answers. Precise definitions for "hard" sciences vary, but the characteristics of "hard" sciences include: producing testable predictions; performing controlled experiments; relying on quantifiable data and mathematical models; a high degree of accuracy and objectivity; and generally applying a pure form of the scientific method
