I think it's fair enough that it is expected by Milton that everyone who claims basic education should know the basics of Darwin's biography. After all, it can very reasonably be claimed that he is one of the three or four most important figures of this rapidly ending millennium. How fortunate it is to live in a country sensible enough to name a city after him. Robert Davidson Brad wrote in part: But there is another implication here: that *everyone* should know the basics of Darwin's biography. Does everyone here know about Giovanni de Dondi's great technological accomplishment ca. 1375? There is also apparently a book somewhere about a remarkable Hellenistic period astronomical clock that may even have exceeded de Dondi's accomplishment -- only ca. 1500 years earlier. Since everyone should know everything, I will appreciate the citations for this item which someone once told me about and which I was so foolish as to not write it down.
