The atom bomb was also speculated in the 19th century, but I now forget the reference. Impossible. Don't be ridiculous. I said 'speculated', not 'built'. The structure of the atom was only discovered well into the 20th century, and the energy equivalence of mass was only suggested in 1905. So? Many things were speculated centuries or millennia before the underlying science for them was known. All you need is enough of a clue to formulate a well-specified hypothesis and an imagination. All right, damn few people have either, but some people have had since time immemorial. Many 'primitive' peoples had beliefs involving ancestral relationships between apes and men. The heliocentric solar system dates from some time before Christ. Rocket-driven space travel was speculated before Newton's laws of motion were formulated. I speculated that there could be non-nuclear DNA years before mitochondrial DNA was discovered. In fact, I also speculated quite a lot of other things about DNA, many of which are turning out to be partially true. I have discovered since that time that a fair number of other people had made similar speculations, some well before I did. Regards, Nick Maclaren. |
