Was Einstein right or wrong in saying:
"If you can't explain it to your grandmother, you don't understand it."?

Well, I presume that the statement means that you should be able to explain it to your grandmother so that she can understand it!

I don't agree with the statement. For example, I don't believe that some theories can be explained in such laymans' terms. There are many popular books out about, say, relativity, but I would hazard a guess that there are people out there who could read the book and not understand the theory.

Relatively speaking, I think an absolute understanding of Einstein's Relativity is impossible. Did Einstein even understand the implications of his own theories?

As for simplicity, though, I think Newton had one up on Einstein; or, further, letting your grandmother be satisfied with the theory of baking cookies would suffice.
