Interesting, however I am looking for empirical evidence to the contrary.

comment What did Marie Curie do for atomic theory?
I still can't see the critical idea which she contributed to atomic theory.

Well I assume it refers to the existance of smaller subatomic particles? Neutrons?

comment What did Marie Curie do for atomic theory?
Thankyou - so now I'm sure you can see what my problem is! The source you quote is one that has confused me most. You will notice that, in fact, what you have put in bold is extremely vague. It states that this was 'absolutely revolutionary' and conceptually important - but what is it she actually discovered? That the ability to radiate did not depend on the arrangement of the atoms itself? If so, why was that revolutionary? JJ Thompson had already discovered the electron, so she didn't discover subatomic particles. How did she contribute to atomic theory with that observation?

comment Find equation for a function of form: $f(x) = Ae^{kx} \cos(Bx+C)+D.$?
Thanks - I seem to get approximately the same answer as Ross, but I'm not entirely confident - can somebody else confirm that?
