As any scientist will tell you, experiments fail more than they succeed. In fact, if you just looked at the amount of time scientists spent on failed experiments compared to successful experiments, you might be tempted to conclude that the real task that scientists are paid for is to fail. However, this failure is necessary. What leaps forward would we make by just repeating old experiments over and over again to prove we could? It’s in the taking of old experiments, analyzing the mechanism, and postulating the results with new compounds and setups that creates leaps forward.
