How can I beat it into you thick head?

We try to categorize knowledge such as Math, Chemistry, History, Psychology. So what is Science?

Science Definition from - http://www.sciencemadesimple.com/science-definition.html

The word science comes from the Latin "scientia," meaning knowledge.

How do we define science?

According to Webster's New Collegiate Dictionary, the definition of science is "knowledge attained through study or practice," or "knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method [and] concerned with the physical world."
What does that really mean? Science refers to a system of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena. The term science also refers to the organized body of knowledge people have gained using that system. Less formally, the word science often describes any systematic field of study or the knowledge gained from it.

What is the purpose of science? Perhaps the most general description is that the purpose of science is to produce useful models of reality.

So what is the point I'm trying to make here?

The http://www.physicsforums.com/ website has more than just physics. Understanding and learning concepts in physics gives us practical applications to use much of the math and chemstry we learned. It isn't just rote learning of concepts we already know but a place to apply what we know as we learn more and expand our knowledge.

This site has great resources for Math, Science, Engineering, and Technology.
