But the larger point is that the next great leaps in research are hybrids of the classic disciplines, Simonton points out. In the last century, we've gained astrobiology, astrophysics, biochemistry, and the like. "When two disciplines hybridize now, the result builds upon the work in the two disciplines. That wasn't always true," he told PopSci. "The new science would completely revolutionize one or both disciplines. Like Galileo's telescopic astronomy."
