Science is about explaining the world and how it works. We hope that you will begin to see that after experiencing this web site. This site explains the very processes that shape and mold the universe. Science is also a process. It is an ongoing thing. New discoveries are made every day. For this reason, some of the things we say in our texts could be slightly inaccurate. Additionally, sometimes it is necessary to approximate things. Basically, this means that in some cases we have simplified a process in order for it to be easier to understand. We have tried to minimize this approximation process, however.

Science and society are intertwined. You will see that as scientific discoveries and processes are revealed, they are applied to society. For instance, the development of nuclear energy is a societal application of science. This application can often lead to controversy and dispute. For example, there are thousands of anti-nuclear protest groups. Some of these groups might be warranted. We hope that after exploring this site, you will understand better the problem with the application of nuclear physics to society: the quandry of nuclear energy.
