Science is a systematic process that progressively builds and organizes knowledge in the form of testable explanations and predictions.
An added thought: science is the universe trying to understand itself.
I took the word enterprise out of the definition because that word makes it sound like science is something that is disconnected from ordinary people. Well, a lot times science is very enterprise like the Large Hadron Collider (LHC). But isn't science also a personal journey? I think every kid with a telescope or a microscope is also doing science. They may not be contributing to science (although they can) but they are beginning the process of learning how science is done. Every now and then science is done accidentally, but usually it is the result of committed individuals often doing hours of tedious work. The scientific process is progressive because previous discoveries leads to new discoveries. This is the real beauty of science. If science is wrong and it does happen, then the process stagnates. When that mistake is corrected, then a virtual explosion of new science is developed. My favorite all time wrong-turn in science, was the idea that the earth was the center of the universe. This idea persisted for some 1800 years after Aristarchus of Samos, circa 280 BC, correctly understood that the sun was the center of the known universe. The reversal of thought resulted in what is called the Copernican Revolution. I personally suspect that there are some wrong turns in science that are just beginning to slow down the natural progression. In engineering and physics there are always assumptions. This I think is where we often get in trouble. A good theory or even a good design process should always begin with a close look at the assumptions.
The theme for this blog is; assumptions in science that may be wrong!
