what did Snow suggest? What it takes a scientist to be successful?Do youWhat do you know about Steven Hawking?Instead of giving up, Hawking went on with his
research, got his phD and married Jane. Nor did he
let the disease stop him from living the kind of life he
had always dreamt of. He continued his exploration
of the universe and travelled around the world to give
lectures. In 2002, Hawking visited China and spoke
to university students in Hangzhou and Beijing. As his
disease has disabled him, Hawking has to sit in the
wheelchair and speak through a computer. He told
the students about his theories and thoughts on some
of the greatest questions: What is time, how did the
universe begin, and what exactly are black holes? In 1988, he wrote A Brief History of Time, which
quickly became a best-seller. Readers were pleased
and surprised to find that a scientist could write about
his work in a way that ordinary people could
understand. In the book, he explains both what it
means to be a scientist and how science works. He
tells readers how discoveries are made and how they
change the world. Science, according to Hawking, is
often misunderstood: people often think that science
is about “true” facts that never change. Scientists,
on the other hand, know that their job is never
finished and that even the best theory can turn
out to be wrong.Do you think Steven Hawking deserves to be
respected and admired? Why?When faced with physical problems---
being disabled, he never gives up and
works on.2. He put the theory of black holes. With A
Brief History of Time, he explained science
in a way that ordinary people could
Understand so that science could be
popularized.3. He attaches importance to passing the
scientific thoughts down to the new
generation, trying to expose more young
people to science and attracting more people
to work on science.If you are eager to make a difference and
become a scientist, what should you do
from now on?devote to study more time which you used
to spend on games and entertainment/
amusement 2. read as many science books as possible3. pay attention to problems existing in the
world nowadays, especially environmental
problems and scientific problems4. try to be admitted into a top university
and get further education abroad
