LISTENING
2 Listen to an interview with a scientist. Which area of science does he believe is the most important today?
Audioscript
Interviewer: Professor Allen. Can you tell us what scientists do?
Professor: Scientists study the world around us-from the tint micro-organisms that live on Earth to distant unknown planets.
Interviewer: Which area of science do you think is the most important one today?
Professor: I’m an environmental scientist, so of course I think that environmental science is the most important! Today, there are a lot of environmental problems in the world, and scientists are trying to solve them. At the moment, I am working with some tiny green plants, which don’t produce flowers when they grow. They live in rivers and in the sea and they grow in sunlight. We are carrying out experiments to grow huge numbers of these tiny plants in water. They are very important, because when they grow, they react to sunlight and produce a liquid. We think that cars can use this liquid in the future.
Interviewer: I see now why so many people think that science is very exciting.

READING
8 Read about a famous scientist. What did he discover?
Ibn Al Haitham was a brilliant scientist who wrote many papers on Physics, Astronomy and Mathematics. He was born in the year 965 CE and died in 1039 CE.
He carried out experiments with light, and the results of which were written down and became his famous book, the Book of Optics. The science we now know as ‘optics’ was born. Ancient Greek scholars had tried to explain how human beings see, but they had not done any experiments to prove their hypotheses. Ibn Al Haitham was able to prove for the first time in his experiments that people can see because light reflects off things around us and into the eye.
Ibn Al Haitham also developed the first camera obscura. In a dark room of his house, he allowed light to come into the room through a tiny hole, and an upside-down picture of the scene outside appeared on the wall opposite. This experiment established the knowledge on which the first cameras were made.
Answer
He founded the science of ‘optics’. He carried out experiments with light. He developed the first camera obscura.
