Interestingly enough that Lewis Carroll quote about the necessity of believing "six impossible things before breakfast" frequently gets used by scientific writers trying to explain what is involved in getting your head round modern scientific ideas about quantum physics and relativity and so forth.

For example it crops up in this Wikipedia piece about Quantum Mechanics, along with another famous quotation, by Niels Bohr, addressing a young physicist - "Your theory is crazy, but it's not crazy enough to be true."
