What Is Science? Philosophy of Science

What is Science?
Science has many definitions and understandings.   When asked for the first time in class at the very first lecture of this course, it sounded a little weird. It was weird because, it is shameful for a PhD student not to think about the meaning or concept of what science after those years doing science (maybe just an illusion of doing science).
Science might be defined as the joint human effort to understand the nature and the phenomenon going around over the world which affects or have the potential to affect the human beings.

As long as they produce and research for new things they got paid.   The same is also true for the scientist those work for for-profit-organizations. They got their salaries or earn bonuses based on what they have added to the organization they are working for.

One of the main underlying facts about doing science is that doing science improves people’s lives. By collecting and accumulating information people have a chance to understand what is going around them.
