theorists don’t have to consider if and how their theories are testable. We the experimentalists must understand the theory and create the experiment to test it. We do the real work—disproving theories to narrow uncertainty, ruling out possibilities, becoming a little less ignorant. We can never prove anything is true; we can only prove something is not true—for now at least. We are the real knowledge seekers, even if we come across as naysayers. Or, as Ernest Rutherford put it, “They play games with their symbols, but we turn out the real facts of Nature.”
