However, any child now visiting the Science Museum can offer the visual proof of the earth's rotation.Anonymoushttps://www.blogger.com/profile/09320614837348759094noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-63239464295252636022014-11-07T14:41:16.751+00:002014-11-07T14:41:16.751+00:00We can only estimate their intellectual ability, w...We can only estimate their intellectual ability, within some wide ranges, but on the basis of the problems there were solving for the first time they were very probably equivalent to 3 standard deviations above the current Greenwich Mean IQ, say at about the IQ 145 level.Anonymoushttps://www.blogger.com/profile/09320614837348759094noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-60217512221141335702014-11-07T14:25:46.330+00:002014-11-07T14:25:46.330+00:00I should have said "at about a thousand miles...I should have said "at about a thousand miles per hour".Jimnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-20561975146925090172014-11-07T13:00:29.691+00:002014-11-07T13:00:29.691+00:00Eratosthenes was undoubtly very smart. The famous ...Eratosthenes was undoubtly very smart. The famous cattle problem was stated by Archimedes in a letter to Eratosthenes. The tone of the letter suggests that Archimedes and Eratosthenes were personal friends. Probably Archimedes studied in Alexandria as a young man and became friends with Eratosthenes there.<br /><br />Eventually the Greeks developed a quite accurate notion of the size of the solar system at least relative to the distance between the Earth and the Sun. They had problems exactly determing that distance. Their proposed methods are theoretically correct but difficult to carry out because of the brightest of the sun. But they knew the distance to planets like Jupiter and Saturn pretty accurately relatrive to the distance between the Earth and Sun. They knew the distance between the Earth and Sun well enough to know that the Sum was much bigger than the Earth. They knew the distance to the Moon and the size of the Moon quite well.<br /><br />Their unsuccessful attempts to measure steller paralax convinced them that the fixed stars were at enormously greater distances than the planets. They guessed correctly that the stars were distant suns.<br /><br />The one thing they got wrong was placing the sun at the center of the solar system and regarding the Earth as being stationary instead of rotating. That the Earth was rotating instead of the heavens revolving was in fact put forward by Aristarchus. I think the basic obstacle to the acceptance of this theory by the Greeks was their intuitive feeling that if indeed we are flying around the center of the Earth at thousands of miles per hour why don't we feel it. People at that time rarely experienced uniform motion at high speeds like modern people do in a jet plane.Jimnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-57232698976924840502014-11-06T01:01:41.716+00:002014-11-06T01:01:41.716+00:00and had their been IQ tests then how would a liter...and had their been IQ tests then how would a literate Athenian in the time of Aristotle have scored vs a German?<br /><br />would it be due to the Athenian's better genes?Anonymousnoreply@blogger.com
