About that "contradiction" word, do not confuse "inability to measure something" with "measuring something and detecting it's not there". Those are too completely different situations, yet many people act like they were the same.

I'm reminded of Semmelweis who figured out an empirical germ theory and beat Pasteur to it by about a decade. Thanks to doctors who "knew" better, he ended up dying in disgrace.

That's not to say I'm anti-doctor, anti-medicine or anything like that. But I am anti-arrogance, especially when people's lives might hang in the balance.
