This means that a theory doesn't need to explain everything in order to be useful. And finally, a good theory is formed from a number of hypotheses that can be tested independently from the theory itself. Any scientific theory must be based on a careful and rational examination of the facts. Facts and theories are two different things. Grandma is finally at an age in which she can take an interest.
