10 Scientific Laws

I came across this link: http://science.howstuffworks.com/innovation/scientific-experiments/10-scientific-laws-theories.htm. I am glad I at least heard of all these 10 theories. The glorious details of some of these are very profound and complex.

However, unless you're some rocket scientist needing those theories, what is the difference between "know it" (like a good student) or "not know it" (like a bum on the street)?

I guess the difference is called enlightenment.
