I also brought to the audiences’ – it was a general audience – to their attention the rate of advance of chemistry which was doubling; the known chemistry was doubling, I think, about every 13 years at that stage. In other words, everything that was known from Adam and Eve in chemistry up till 1961 would be approximately doubled in the next 13 years. How do you cope with this at a university? And to illustrate this point, I brought the current volumes of chemical abstracts, which was one year’s, tens of thousands of journals, publishing hundreds of thousands of papers. How do chemists keep up with this, the transfer of knowledge? All of this was part of the thoughts that I was working on in the inaugural lecture. And, again, I was emphasising the point that in universities you must be prepared... preparing students for things which are changing; it’s not a static world, it will be changing all the time.
