Your Most Controversial Opinions!

Physics, Chemistry and Mathematics are fake sciences?
And possibly religious?May I ask why and what exempts biology from this?
I know you explained this to me before crashfrog, but the discussion got kind of cut off half way.Edited by Son Goku, : No reason given.

That's just a restatement of what was just said. In what sense does biology study the real world and not theoretical models above physics and chemistry? (I'll leave maths out)It's chemistry in particular I don't understand. Surely it models the real world in the same sense as biology. Chemistry, physics and biology are all carried out in a different manner to one another and this leads to these kind of inter-subject criticisms. Physicists often say that Biology and Chemistry are just stamp collecting and Chemists often say Biology and Physics are both too acedemic and "Hey, let's test this idea"-based. Biologists often say crashfrog's comment above.However I've obviously managed to get an explanation out of Physicists for their comment and I've had enough contact with Chemists to get them to explain their view. Unfortunatly I don't get to talk to biologists much, so I'd like to hear more about this, if you don't mind.

That's just first year undergrad mechanics though, which contains problems that a student can solve in a reasonable length of time. Real world pulleys can be done easily, they just don't give any extra insight into anything, though they are extra work, which is why they aren't given to students. Same with the rest of you examples, they're simplifications made for course work, not actual simplifications made in working physics.
