in my previous posts. It's my understanding that a material law is more than a norm. If you find exceptions to the material law, we then have a great interest in refining the law, such as the interest in how Einstein's work applies to Newton's. Did we measure exceptions to Newton's
"laws?" Yes. Some day we might exploit even more of those exceptions than we have already... to give us more ways to travel, communicate and
conceptualize the grand mysteries.
