Antiscience appreciate humour in so serious a matter. But the most they were able to pin on Condon, as I recall, was that in high school he had a job delivering a socialist newspaper door-to-door on his bicycle. Imagine you seriously want to understand what quantum mechanics is about. There is a mathematical underpinning that you must first acquire, mastery of each mathematical subdiscipline leading you to the threshold of the next. In turn you must learn arithmetic, Euclidian geometry, high school algebra, differential and integral calculus, ordinary and partial differential equations, vector calculus, certain special functions of mathematical physics, matrix algebra, and group theory. For most physics students, this might occupy them from, say, third grade to early graduate school - roughly fifteen years. Such a course of study does not actually involve learning any quantum mechanics, but merely establishing the mathematical framework required to approach it deeply. The job of the popularizer of science, trying to get across some idea of quantum mechanics to a general audience that has not gone through these initiation rites, is daunting. Indeed, there are no successful popularizations of quantum mechanics in my opinion, partly for this reason. These mathematical complexities are compounded by the fact that quantum theory is so resolutely counterintuitive. Common sense is almost useless in approaching it. It's no good, Richard Feynman once said, asking why it is that way. No one knows why it is that way. That's just the way it is. Now suppose we were to approach some obscure religion or New Age doctrine or shamanistic belief system sceptically. We have an open mind; we understand there's something interesting here; we introduce ourselves to the practitioner and ask for an intelligible summary. Instead we are told that it's intrinsically too difficult to be explained simply, that it's replete with 'mysteries', but if we're willing to become acolytes for fifteen years, at the end of that time we might begin to be prepared to consider the subject seriously. Most of us, I think, would say that we simply don't have the time; and many would suspect that the business about fifteen years just to get to the threshold of understanding is evidence that the whole subject is a bamboozle: if it's too hard for us to understand, doesn't it follow that it's too hard for us to criticize
