(...) They did indeed change it, from more of a "This is the Universe" to "This is me and the Universe I live in" kind of feel. (...) Minor nit: Air is not required for sound, but matter is. Similarly, as the "no sound in space thing" goes: If you (...) (22 years ago, 12-Nov-02, to lugnet.off-topic.geek)

I love Firefly, it captures the essence of what space-based civilization would be like in real life. I mean Star Trek paints a nice picture but real life isn't like that. In Firefly, each world has its own unique culture and technology level like (...) (22 years ago, 12-Nov-02, to lugnet.off-topic.geek)

(...) Do it! The trick is to get rid of everything else you have built and use some abundant color, like red one the inside. Remember, red shag is the carpet of the future! Good luck! --Kyle (URL) (...) (22 years ago, 12-Nov-02, to lugnet.off-topic.geek)

(...) Hey, that's super! And I finally found an online reference at the U of Georgia site, so I can probably handle these in the future. Thanks for the clear explanation and the solution. Dave! (22 years ago, 11-Nov-02, to lugnet.off-topic.geek)

(...) Oops. Hang on there Adrian, read for content. The five points as given in the initial problem (including 0,0) will not solve to a simple parabolic equation. Eliminating 0,0 does give us the solution specified above. Bleh. Adrian (22 years ago, 11-Nov-02, to lugnet.off-topic.geek)

(...) Sorry, but this doesn't go through 0,0. Solving x=0, y=0 gives 0=855/11, which is clearly not true, so this isn't the equation he's looking for either. Adrian -- www.brickfrenzy.com (22 years ago, 11-Nov-02, to lugnet.off-topic.geek)

(...) Yes, it does. If you just have the last four points to work with, then you definitely have an upward-turned parabola, symmetrical about the y-axis. Here's what you have to do to find the formula for a parabola, given three points: y = ax^2 + (...) (22 years ago, 11-Nov-02, to lugnet.off-topic.geek)

(...) Oops - I'd better correct myself before else does. Your parabola does NOT exist. It is NOT symmetrical. I solved it for the three points with x > 0 My bad. :( Jeff J (22 years ago, 11-Nov-02, to lugnet.off-topic.geek)
