San Jose, Ca Lines: 15 Summary: Daedalus, Venus Nifty piece on atmospheric refraction in _The Inventions of Daedalus_, a collection of articles from The New Scientist. According to Daedalus, if the earth were 13 km less in radius, the bending due to atmospheric refraction would be equal to the curvature of the earth. Neat. On a clear day, you could see the back of your head (given a good telescope and a lack of mountain ranges). I remember an article on Venus where it stated that due to atmospheric refraction, the ground would appear to curve upwards when viewed from its surface. I think the Soviets have gotten pictures back from the surface-- was this affect noticeable? david rickel decwrl!sci!daver
