[Q] There is a paper in the post-war period that, I think, illuminates a facet of your character which one doesn't usually associate... and there is a paper on the origin of the chemical elements with colleagues Alpher and...

Oh, never mind that, it was wrong. Chemical elements...

[Q] No I meant more the authorship of the paper, rather than the paper itself.

Well that was just a cheap joke. The authors were Alpher, Bethe and Gamow, but it turned out that the theory was wrong. Chemical elements are not made in the Big Bang as Gamow had assumed, but they are made in big stars when they obtain temperatures well beyond the carbon formation temperature, then successively heavier elements are being built up. And once you get to really high temperatures, you get the development of neutrons, and neutrons are then added to... to nuclei such as iron, making the heavy elements, including the radioactive ones.
