Science Is Of Value Because It Can

If You Can't Explain Something To A First Year Student, Then You Haven't Really Understood .

To Test Whether You Have Learned An Idea Or A Definition, Rephrase What You Just Learned Without Using The New Word.

It Is Necessary For The Very Existence Of Science That Minds Exist Which Do Not Allow That Nature Must Satisfy Some Preconceived Conditions.

Scientists Are Explorers. Philosophers Are Tourists.

Although It Is Uncertain, It Is Necessary To Make Science Useful. Science Is Only Useful If It Tells You About Some Experiment That Has Not Been Done; It Is Not Good If It Only Tells You What Just Went On.
