After commenting on the confusion between different clichés about physics and physicists in reporting about Angela Merkel, I feel obliged to note this sentence, from an article in the New Statesman about the fake traveller-tourist dichotomy:
The rush to witness the “authentic” ultimately alters the reality, in a kind of behaviourist butterfly effect.
Once again, physics clichés are being confounded. When you’re looking for an educated-sounding way to make the banal observation that it’s hard to observe things without getting mixed up in them, and so changing them, the cliché you want is “uncertainty”. The “butterfly effect” is what you cite when you’re bloviating about how small actions can have large long-term effects.
It’s slightly depressing for anyone who has hopes for general science education. It suggests that even if you come up with compelling ordinary-language metaphors for scientific concepts, the result will just be a salad of interchangeable expressions gesturing vaguely at an undifferentiated mass of physics woo-woo concepts.
