Empiricism = Oh, yeah?? Prove it!

This means that you have to try things.
Chemistry is NOT an intuitive science--it is the essential experimental process.
Just because something tastes tart or tangy, for example, doesn't mean it's acidic. Many acids are tart, but so are some bases. And either type of substance can be corrosive. The issue isn't taste, or corrosion, it's HYDROGEN ION concentration, which has to be tested or measured.
Science is for skeptics--people who like to prove or demonstrate stuff for themselves.
In that sense we scientists are all from Missouri--show me!
