Dextro and laevo organic chemicals (what DrM was talkign about) are actually responsible for most tetarogens (literally 'monster formers'). Thalidomide has dextro and laevo forms - the laevo is very useful for combatting mornign sickness and so the drug ws prescribed. Unfortunately no-one thought of screenign the dextro form, which turned out to be a tetarogen and that is what the drug is now known for.
Louis Pasteur, as well as inventing pasteurisation, invented the smallpox vaccine by the art of noticing that milkmaids rarely contracted the disease. Pasteur theorised that they'd caught cowpox, a bovine affliction with little effect on humans, and this somehow made them immune from smallpox. To test his theory he got a small boy and gave him cowpox. Then, after allowing the cowpox to take its course, he took the same boy to a smallpox sufferer. He scratched one of the boils of the smallpox sufferer and then scratched the boy's arm. The boy survived.
Interesting scientific methodology.
If every person in France joined hand in hand to encircle the Earth, 2/3s of them would drown. Think we should experiment?
