I think it was my revulsion from the stupid names of the constellations that put me off. On the other hand, the round earth notion seemed second nature to me - anyone who lives by the sea ought to find it intuitive, and anyway the moon looked round so why not the earth?<br /><br />If I remember correctly, there was a way of indirectly observing the sun that revealed its roundness too, but I can't remember the trick of it. deariemenoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-6208681110313667452015-10-01T09:13:18.830+01:002015-10-01T09:13:18.830+01:00Yes, correct, all this whizzing about has confused...Yes, correct, all this whizzing about has confused me.Anonymoushttps://www.blogger.com/profile/09320614837348759094noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-80546520624514822242015-10-01T08:27:46.521+01:002015-10-01T08:27:46.521+01:00“So, 30% of British adults thought that the observ...“So, 30% of British adults thought that the observed passage of the sun in the sky meant that our star obligingly whizzed round us. 16% imagined it did so once a day, as per visual observation of the same apparent phenomenon.”<br /><br />16% thought the earth took a day to go round the sun.Haroldnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-3858132698298091192015-09-30T06:07:34.439+01:002015-09-30T06:07:34.439+01:00Here's a video, "A Private Universe,"...Here's a video, "A Private Universe," of Harvard students and working class high school students both explaining that it's colder in winter because the earth is further from the son:<br /><br />https://www.youtube.com/watch?v=TrXaQu_qGeo<br /><br />Both demographics give the same wrong answer, but the Harvard students are vastly more self-confident and delighted with their own cleverness.Steve Sailerhttps://www.blogger.com/profile/11920109042402850214noreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-16984259360508467532015-09-29T09:18:14.447+01:002015-09-29T09:18:14.447+01:00Thanks.
