Qian changed his major because of a shift in personal interest.
Qian’s strong interest in art has a positive impact on a scientist’s development.
When Hawking was young, almost everyone believed that the universe began with a big bang.
Because Hawking was determined, he was able to succeed even though he was ill.

Answer the questions below using the information from the texts.
Why was Qian called “the father of China’s aerospace”
How was Hawking’s own theory proven correct
Because much of the technology behind the Shenzhou rockets was based on his research.
Astronomers used their telescopes to prove his work on the big bang theory.
Study the language and structure.
1. Underline the linking words and phrases in the passages, and describe their
function.
However, after the Songhu Battle broke out in 1932, ...
At that time, China was poor and its rocket science was undeveloped.
Nevertheless, Qian did not let that discourage him...
Because much of the technology behind the Shenzhou rockets...
However, what might have made him such an outstanding...
In general, there were two main theories...
Besides being brilliant, he was brave, ...
Furthermore, he was quite determined.
Above all, Hawking was willing to admit his faults.
These linking words serve to link elements in the passages and bring greater cohesion and logical flow to it.
Study the language and structure.

Qian Xuesen
Stephen Hawking
a man with “great scientific thought and scientific spirit” who was patriotic and served his homeland with effort, achievement and devotion;
a pioneer;
did not let that discourage him;
determined;
an outstanding and creative scientist;
deep appreciation for art
brilliant;
brave;
sometimes careless in what he said or did;
willing to say what others were afraid to say;
dream of what others were afraid to dream about;
quite determined;
willing to admit his faults
Study the language and structure.
3. Find words that describe the personalities of the scientists. How do the stories
about the scientists help illustrate these personalities
In the case of Qian Xuesen, we see his determination illustrated by his struggles and how he overcame challenges. His story also shows he was patriotic and devoted to his career. In the case of Stephen Hawking, we also see his determination in the face of difficulty through the stories told about him. We also see his audacity.
While-writing
Write an essay about the scientific spirit.
1. In groups, discuss some stories about great scientists.
Newton and the apple;
Watson dreaming of the structure of DNA;
Fleming’s accidental discovery of penicillin;
...
Write an essay about the scientific spirit.
2. Using these stories as a basis, discuss the following questions:
Apart from being clever, what are the most important personal qualities a scientist must have to be successful
How do these stories illustrate the scientific spirit
A scientist must be lucky, to an extent, but a part of that luck is noticing what others might gloss over. For example, Fleming noticed that something was odd about a sample in a Petri dish, and he did not throw it away. The intuitive and creative power of a great scientist also needs to be taken into account, as illustrated by Watson’s dream which showed him the structure of the DNA.
3. Now work by yourself to write an essay about the scientific spirit.
Great Scientific Minds
When we consider the great minds of many centuries and ask the question of what makes someone a great scientist, there are many aspects we should evaluate. But which ones are most important Is it their inventions, cures, or solutions to problems Is it the personal challenges they had to face Or is it their overall character
Looking at the lives of Qian Xuesen and Stephen Hawking, some common characteristics surface: they are knowledgeable, gifted, self-sacrificing for the greater good of the country or humanity, brave, and determined. In short, they have to tenaciously chase down solutions to big problems and not let discouragement set in during their discovery process.
We can see this in Qian Xuesen’s life, pioneering to another country to work with and inspire like-minded people in his field and to collaborate on their work. We can see it in his vigour to return to China and lead their aerospace programme through its birthing stages.
Sample Writing
We saw the determination and devotion to accuracy and truth on the part of Stephen Hawking from his youngest days through the decades he fought for his body while his mind progressed into the arena of geniuses.
The definition of scientific spirit is to, above all else, be willing and able to grasp a problem or a question and not let go of it until knowledge, creative power, and collaboration have brought a clear answer. Then this same mind must believe in its findings enough to bravely present them, prove, and perfect them for the betterment of the quality and sustainability of life all over the world. It is to look squarely, ask questions, and never give up trying.
