My interest in science developed by the question:
Is there any process that can vary an invariant?
Later, I found that the entire enterprize of science, philosophy and religion are based on the answer to this question. No process can vary an invariant. This is the only statement that summarized all my experience as a student, as politician, as representative, as a father, as a son, as a scientist and as a teacher.
You can also try to devise the methods and identification of invariants in life - it will give you every science you are yet to learn.
