Linus Pauling: So in 1940 the German physicist Pascual Jordan...who had worked with Born on matrix mechanics -- of course, knew physics,
didn't know any chemistry, I'm sure -- wrote a paper in which he said that the gene duplicates itself because, according
to quantum mechanics, two identical molecules interact with one another more strongly than a molecule and a non-identical
Max Delbrück met me on the campus and said that Jordan had published that paper, which I said was nonsense. So Delbrück and
I published a paper saying that we had calculated the magnitude of the energy of interaction and it was just completely negligable
-- this special quantum mechanical interaction between like molecules of the dimensions of molecules that are present in the
human body. And that, in fact, the gene consists of two mutually-complementary strands, and the gene duplicates itself by
the unfolding of a pair of mutually-complementary strands so that each can act as a template for the synthesis of the other.
