"SDaryl" wrote in message oups.com... If the person keeps up with contradictions (as you do), then that is prima facie evidence that he *doesn't* understand it. Your logic is ****ed and so are you. Do you want to learn how the cuckoo transforms you rely upon so heavily are derived or not? Androcles. |

"SDaryl" wrote in message oups.com... | It's as if you claimed that you know how to fly a helicopter, but every | time you try to fly it, it crashes immediately. That's evidence that | you *don't* know how to fly a helicopter. I know how to fly a Harrier. I worked on building a simulator for the Royal Navy AND another for the Indian Navy for over two years, debugging and testing. I've ridden in a two seater Harrier trainer at Yeovilton, engine running, but was not allowed to fly it. I had to settle for taxiing. I've flow a Lynx helicopter simulator in Germany at the British Army base in Detmold prior to the cold war. I didn't crash. I crashed a Boeing 747 flight simulator trying to fly *between* the twin towers of the World Trade Centre with a 90 degree roll to avoid the wings hitting. That very simulator was later stolen from Kuwait by the Iraqis and later recovered after the first Gulf war. I've hang-glided. Don't tell me I don't know how to fly, you only know how to talk out of your arse. Androcles. |

Hi Perspicacious, You imagined that one must know math to understand the Twins_Paradox. I beg to differ, check out this mathless explanation: http://Faraday.Physics.UToronto.CA/P...winParadox.swf Then check out all the other .SWF files there... cool stuff maynard ! http://Faraday.Physics.UToronto.CA/P...SpecRel/Flash/ |

That only illustrates that Einstein's calculation of 1905 (and which subsequently resulted in the paradox) is self consistent about what everyone observes *as based on Lou's pov*... - Very nice one nevertheless :-) Harald |
