Quote by Albert Einstein
You do not really understand something unless you can explain it to your grandmother.
Summary
This quote highlights the importance of simplicity and clarity in explaining complex concepts. It suggests that true understanding of a subject or idea can only be achieved when one is able to break it down to its simplest form and communicate it effectively to someone who may have no prior knowledge or expertise on the matter, like a grandmother. It reflects the idea that the best way to test one's understanding of a topic is to try and explain it to someone unfamiliar with it, which encourages a deeper level of comprehension.
