answer:
i think making mistakes are the key to making new discoveries. scientists have learned many things due to their own mistakes. thomas edison once said that inventing was 1% inspiration and 99% perspiration. the typical or usual role of a mistake in science is not to lead to a brilliant invention, but to teach the next scientist(s) how to do better the next time around. as space physicist carl sagon once said, "science is a self-correcting process". what i believe that means is that science like marriage cannot be rushed.
wishing you the best of luck :)
hopefully, this helps
have an awesome day !!
