Knowledge

General Information   |   Is This Course for Me?

Read a dictionary definition. Do you agree with it? Can you suggest revisions?

A basic maxim says that if we know some facts, we also know everything which can be inferred from them. Do you agree? Why?

Is there a difference between knowledge and data? Can you divide the information stored in your brain to knowledge and data? What typical facts are in each class?

If I tell you the solution to a puzzle you couldn't solve - is knowledge transfered in this process? Can you explain what kind? Is it the same as when I tell you the result of a calculation you cannot perform? The content of a movie you haven't seen?
