quote seen on an A level chemistry webby:

Warning! If you like your chemistry all tidy and simple, don't read any further. I have got to the point that most text books get to at this level. In fact, as I will show below, it is quite difficult to show this effect of ionic radius in any simple ions. There are too many exceptions.

oh boy i love this quote. imagine me saying: "alwyn... if you like your astrophysics tidy and simple dun go any further without understanding calculus, trigo, series, summation, tensors, gamma function..." oh my i'm courting death...
