Obvious why when you know that they move about! "Planet" literally means "wandering star". And then came along an English clown called Newton who couldn't comprehend that the 'wandering' nature of planets refers to retrogrades and retrogrades are an illusion caused by the Earth's own orbital motion between Venus and Mars and around the central Sun.A teenager with the benefit of contemporary imaging and time lapse footage can figure out what Isaac and his followers couldn't - http://apod.nasa.gov/apod/ap011220.html There's your wandering motion for you Brown and the same teenager could probably tell you that Isaac's idiosyncratic view of retrogrades is a technical non sequitur as it doesn't involve a hypothetical observer on the Sun - only an intelligent observer who realizes he is standing on a moving Earth ! - "For to the earth planetary motions appear sometimes direct, sometimes stationary, nay, and sometimes retrograde. But from the sun they are always seen direct,..." Newton As a genuine astronomer,I can see what Isaac was trying to do with his absolute/relative time,space and motion using that worthless idea of retrogrades but I wouldn't hold my breath waiting for somebody else to ask what exactly he was up to and why it is catastrophically disruptive for 21st century purposes.Apparently the English like their iconic figures and certain sections of your nation seem terrified of certain individuals then as now judging from the recent celebrity exposure and Newton has such a grip on science that demonstrating what he was actually doing looks like an assault on the English nation. Wlliam Blake got it right even though he didn't know the technical ins and outs of Newton's clockwork solar system approach which borrows from Flamsteed's muddleheaded conclusion which takes a step too far with a rotating celestial sphere of Ra/Dec. "I turn my eyes to the Schools & Universities of Europe And there behold the Loom of Locke whose Woof rages dire Washd by the Water- wheels of Newton. black the cloth In heavy wreathes folds over every Nation; cruel Works Of many Wheels I view, wheel without wheel, with cogs tyrannic Moving by compulsion each other: not as those in Eden: which Wheel within Wheel in freedom revolve in harmony & peace." William Blake,Jerusalem Cruel works indeed !,the cruelty will be returned if the English do not deal with the mess which occurred within their borders and specifically the train wreck involving astronomy and human timekeeping.The Americans have already begun the recovery process- http://www.youtube.com/watch?v=kDWHM00sZJc BTW It would be nice to know if these replies are reaching spacebanter.com and if the OP is still there. I hope he hasn't been frightened off by Oriel36 blather. -- Regards, Martin Brown |
