We have to assume that chemistry is chemistry, and that physiology or medicine is sort of biology. If there is a discovery in biochemistry, the decision is very difficult whether it should be awarded the chemistry prize or the physiology or medicine prize.” At some point, it has been ...

On a different path, Lowry (1923) knew the electron valence theory of Lewis (1923) and relied on it to distinguish two types of chemical affinity (polar and non-polar) and their links in organic and inorganic substances, which led to the need of proposing H3O+ as what is exchanged in ...
