My first day in Quantum Mechanics class, the professor stood in front of the lecture hall and looked out at the 70 students before him. All had their notebooks out, and all were ready to learn this crazy-sounding field they'd only heard about before.
"How many of you," he asked, "are physics majors?" About half the class raised their hands. I was one of these.
"Good," he said. "You belong here. Now, how many of you are math majors?" About a quarter of the class raised their hands.
"Good. This will be a useful and interesting course for you. Now, how many of you are engineering majors or chemistry majors?" Most of the rest of the class raised their hands.
"Impressive! You're fine." Then he gritted his teeth and said in a much, much lower--I would even go so far as to say threatening--tone, "Now how many of you are philosophy or religion majors?"
Two students raised their hands. The professor proceeded to yell the loudest F-word I have ever heard in my life. And I'm a high school teacher, so... I've heard some pretty intense ones. This was the F-word that ate all those other puny cusses in one fowl bite.
When the echo died down, he said, "Alright, now LOOK. Here's the deal. There's more [expletive] written about Quantum Mechanics by people who don't know anything about it than there are actual books on the subject. People use the word 'Quantum' to justify beliefs in alternate universes, multiple consciousnesses, miracle medicines, and a bunch of other things. There are unfortunate phrases in this course, like 'The Uncertainty Principle,' which people take so far out of context it's not funny. To you who are philosophers and wish to learn this stuff, I'm not kicking you out of class, but be aware: this is a science course. Everything here is backed by data and experimentation. QM isn't a well-respected theory because of uncertainty or philosophy; it's respected because it is one of the MOST supported by evidence in the history of science. This is a science for the hard skeptics, for the doubters, for those who need to see to believe. If you need to believe things you can't see, this course will disappoint you. You'll do hard math. You'll see clear results. That's the way it is. And anyone who tells you QM is anything else is either ignorant or lying through their teeth."
And that's about all there was to say about the subject of philosophy in that class.
