You don;'t fly. Well, I think he made a pretty good "guess" - the GE90-115B tha powers the 777 turns (front fan) at 2550RPM, or 42.5 RPS. He probably didn't ahve to guess much, as these facts are easily and irrefutably verified. I obtained the facts from the engine specifications, so no guessing was required. But you have no idea what any of that means, do you? Bertie |

So, which way is the naked lady spinning? http://www.sonnyradio.com/spinninglady.html I called it up and saw her rotating CCW for about a minute even after bleinking and looking around the room and then back at the pic she was still CCW. Then I looked up and book marked the page and and then sent a link to my wife and when I looked back she was CW. And just now I popped back over and she is still CW. |

You are hear to argue about aviation discussions and I understand completly why you do it. It is because you have some psycological need to argue and if you did it the way you do here you would get your ass beat. |

There are many real life environments where you might see stroboscopic
effects without there being a flashing lamp. The optical 'opposite' like when you've seen wheels seem to move backwards is if your line of sight can be mechanically inturrupted somehow, or even systematiclly vibrated or jarred. Coming up on a truck, for example, if your view of the front wheel is influenced by the lug nuts on an aft wheel, can offer that impression. A badly out of balance wheel on your car, moving your head at the right frequency, can do the same thing. There are probably other circumstances as well, but I can't at the moment think of one where steady state viewing of a rotating wheel or the like without something like a pseudo shutter influencing your vision would cause it. So no, your vision is not defective. Or more correctly, it may be defective, but not because of what you've noted in your post! |

Wikipedia usually quotes, at best, a number of sources, which may or may not be reliable, be they scientific papers or not. Ok, I'll rephrase that so even you can understand it: "This particular Wikipedia article quotes multiple scientific papers, all of which prove that you're talking out your ass. So far, all you've offered in rebuttal is your own proven track record of being wrong about everything to do with everything, and your own failed and pathetic life." -- Paul Tomblin http://blog.xcski.com/ I tried staying in during a fire alarm some years ago. Unfortunately the fire warden wouldn't accept 'A real hacker goes down with his newsfeed' as an excuse. -- Peter Gutman |

... Yes - I have a name writes: I'm sure I've seen wheels on cars that appear to be moving backwards. Are my eyes defective? No, but your memory is imperfect. You've never seen that in real life, only on TV and in films, or under stroboscopic lighting. I saw it again today driving to work. |

I looked at first and saw CCW and after a while, I looked at the foot and saw CW and scan upwards and still see CW... But if I look away and back at the top, I see CCW again. -- Jim in NC |
