  Re: URL: Fifty Innovations Driven By NSF Research Funding
 
(...) Whew, good thing the NSF funded that. Otherwise, we might be stuck with a shrinking universe, and who wants that? (...) See, now, if you ask me, I'd say they could have skipped that one. (22 years ago, 9-Jan-03, to lugnet.off-topic.geek)
 
  Re: Top 1000 noisemakers
 
(...) If I'd only known what I'd be starting! Heh. A) Yeah, good mouse tactic, but I dislike using the mouse unless I have to. B) I always forget the exact keycombo for straight to the end, thanks. C) yep. but that goes without saying. OR DOES IT? (...) (22 years ago, 9-Jan-03, to lugnet.people, lugnet.off-topic.geek)

(...) And note that either way you select your huge chunk, you can use shift and cursor keys to adjust the end of the selection. You can also re-adjust the end with a shift mouse-click. FUT: lugnet.off-topic.geek (22 years ago, 8-Jan-03, to lugnet.people, lugnet.off-topic.geek)

Lots of geeky things listed here on this US National Science Foundation page. (URL) Nifty Fifty: Innovations Driven By NSF Research Funding 1. Accelerating, Expanding Universe 2. American Sign Language Dictionary Development 3. Antarctic Ozone Hole (...) (22 years ago, 8-Jan-03, to lugnet.off-topic.geek)
 
  Re: A space physics question
 
(...) it's all relative isn't it. you could set up a thruster system to ensure that your anchor point wouldn't move, relatively. (...) yes, again, this is possible the key here is that you zig zag points stay the required distance apart. (...) this (...) (22 years ago, 29-Dec-02, to lugnet.off-topic.geek, lugnet.space)
 
  Re: A space physics question
 
(...) weight in space so we'll talk in inertia or mass. If you are a single person winching a large object such as a ship or asteroid or other large mass... then if we apply Einstein's space-time theory the object with the larger mass will move less (...)

This is where the force equations will hit you hard :-) The next pulley will suddenly get a great force through the line, and needs to increase it's thrust (...)

  Re: A space physics question
 
(...) I'll say "sure" but with this question as a follow-up. Pulleys are usually used on Earth to gain a mechanical advantage. In space, since the object is weightless (but still has mass!) there isn't the need for the pulleys... at least as far as (...) (22 years ago, 29-Dec-02, to lugnet.off-topic.geek, lugnet.space)
 
  Re: A space physics question
 
(...) ... (...) It would be far more efficient to attach thrusters to the object being winched and move it to that location - or, if that is not possible, attach the tether line (which you've got on your object being moved) to a tow ship. Assuming (...) (22 years ago, 28-Dec-02, to lugnet.off-topic.geek, lugnet.space)
 
  A space physics question
 
Imagine a winch pulling a rope or cable through a series of pulleys (horizontal) that are staked to the ground. The pulleys are arranged so that the rope makes a zig zag pattern on the ground. There is an object at one end of the cable, being reeled (...) (22 years ago, 28-Dec-02, to lugnet.off-topic.geek, lugnet.space)
