 | | Lego Mosaic Customer Service call
|
|
Hey, everybody - I ordered 3 mosaics today, and I just got a call from S@H customer service checking to see if they were all real or if I had accidentally duplicated an order. My 3 mosaics are my sister, my brother, and Jeri Ryan (by accident) - (...) (24 years ago, 9-Nov-00, to lugnet.off-topic.geek, lugnet.lego.direct)

(...) basic (...) The only Law of Gravity is that it exists. Many *theories* of gravity of been used to explain it, Relativity being one of the most recent (prior to that, Isaac Newton's was used). Paul Davidson (24 years ago, 9-Nov-00, to lugnet.off-topic.geek, lugnet.space)

(...) acceleration _is_ absolute - you can measure it, you can tell when your speed is constant. you _cannot_ tell what that speed really is though. not without a point of reference.

(...) Yeah, that's what I don't get, as well. The terms "inertial" and "noninertial" come from the britannica article, and they mean "non-accelerating motion" and "accelerating motion". But I'm not sure how to tell which is which without an absolute (...) (24 years ago, 8-Nov-00, to lugnet.off-topic.geek)

Do we infer that the ground-based clock decelerated sufficiently to (...) (24 years ago, 8-Nov-00, to lugnet.off-topic.geek)

Just looked this up in Britannica Online. (Search for "time dilation"). Acceleration definitely plays into it. *All* clocks in non-accelerating motion relative to an observer run slow by his/her frame of reference. (Thus potentially causing (...) (24 years ago, 8-Nov-00, to lugnet.off-topic.geek)

(...) The actual slowing takes place during acceleration, but it will persist at the slowed rate once acceleration ceases, lasting until the traveler drops back into the other (apparently stationary) inertial frame. Dave! (24 years ago, 8-Nov-00, to lugnet.off-topic.geek)

(...) Does this mean once a person is travelling at a particular velocity (e.g. .99c), he will not feel any further time dilation effects if he is no longer accelerating? IOW, is time dilation only experienced during acceleration? Jude (24 years ago, 8-Nov-00, to lugnet.off-topic.geek)
