“The history of being spectacularly right has a shadow history lurking behind it: a much longer history of being spectacularly wrong, again and again. And not just wrong, but messy. A shockingly large number of transformative ideas in the annals of science can be attributed to contaminated laboratory environments. Alexander Fleming famously discovered the medical virtues of penicillin when the mold accidentally infiltrated a culture of Staphylococcus.”

“Do not be too timid & squeamish about your actions. All life is an experiment. The more experiments you make, the better. What if they are a little coarse, & you may get your coat soiled or torn? What if you do fail, & get fairly rolled in the dirt once or twice? Up again, you shall never more be so afraid of a tumble.”

Ralph Waldo Emerson
