A wise man once said:
“All of physics is either impossible or trivial. It is impossible until you understand it, and then, it becomes trivial”Ernest Rutherford
I am wary of people who are quick to throw around the “impossible” word, or those quick to reject some new idea as not practical. It is neither a sign of intelligence nor maturity. It is usually a sign of ignorance and illiteracy to reject a new thought or idea without clearly articulated reasons. Our daily living does not require us to think and challenge every idea out there, and as such, we fail to recognise that everything we consider normal today was not always so.
I think that by definition; nothing is possible and nothing can be done until someone, someday proves it can be done. An agent of change must understand that no progress is to be had by rehashing current ideas (Albert Einstein calls it madness). Progress would demand that we rethink what is possible, aim for a better understanding about why EXACTLY something is considered impossible.
Did you give up on your quest because “they” claimed it was impossible or did you actually hit a brick wall you couldn’t demolish?
“Never tell a young person that anything cannot be done. God may have been waiting centuries for someone ignorant enough of the impossible to do that very thing.”G. M. Trevelyan
