Free Science is knowledge that somebody has already paid for so you don't have to and that is made available to you for free. Even though the process of obtaining scientific knowledge has been paid by the people it is usually sold back to them as an additional service at additional cost (subscription). This phenomenon is today's reality. However, with development of the Internet the situation is changing. We are here just to help this trend.

The term science also refers to the organized body of knowledge humans have gained by such research."
