When failure equals success

In this article, the author talks abut how failure important, not only in science but also, in life. If it weren't for failing a few times, science probably wouldn't be as accurate as it is. To prove his point,  the author uses real life examples of replication failure that have happened in the past like Loewi and his experiment. If he hadn't tried time after time we would have inaccurate information about neurotransmision. I agree with the author because in order to succeed and be accurate with your work,  you need to fail and learn from your mistakes.
