What is science?

After reading Asimov's Guide to Science, What is science, I feel lucky that I am now living in the modern society where induction is equally valued as deduction. Otherwise, people like me, who constantly conduct empirical research were regarded as "slaves" in the past.

As far as I am concerned, I do not think Asimov has explained clearly what is science. He only defines science in terms of what is the drive of science and how to do science. Specifically, he helds that curiosity is the ultimate drive of science and science is the result of being angry of bordem. In other words, science is a kind of upper-construction. In terms of how to do science, Asimov mentions induction and deduction.

So what is the ultimate goal of doing science? At the very beginning, te byword of science, curiosity is used to help people find food. When food is no longer a problem for people, what is the point in pursuing science? Asimov does not explain this well in the chapter. In my opinion, like people use the curiosity to find food in the past, today people still use science to find "food". But today "food" refers not only to things people eat, but also more comfortable life. Science is used by politicians to better control their people. Because if people have no food to eat, no house to live in, they will rebel.
