"You can have all your scientific method down, all your experiments done accurately and recorded in minute detail. But most of the significant, universe-changing advances in science were not done by methodically plodding ahead with reasonable steps. Things like Einstein's theory of relativity or the foundations of quantum mechanics came about more as hunches. Scientists talk about a theory being elegant - it just feels right. Sometimes you have to just trust your instincts. People often talk about following your head or your heart, but sometimes there's a deeper feeling you follow. Sometimes you follow your guts, your instincts. Scientists are also trained to do that."
