"what shape on a 2 dimensional graph do you get when you intersect a flat plane and a double napped cone parallel to the generator?" Or "what is the degenerate form of an elipse".

Uhhhhh huh? LOL. I have no idea what you just said let alone the answer to them! See? That would then mean that you would not only have to be over 18 to post here, but a genius as well. LMAO.

Well, not a genius..you've just been out of high school math class longer than me (also, I have taken many math courses such as linear algebra and single/multi variable calculus as requirements of my degree). You proved my point though, it would not be fair to use that sort of question and that's why I used them to demonstrate why Mobius' idea was inherently flawed.

Also, in case anyone gives two shits..here's the answers!!

1)what shape on a 2 dimensional graph do you get when you intersect a flat plane and a double napped cone parallel to the generator?

This one's trickier than the second one. It actually has 2 separate cases that should be included in a full answer. If the plane intersects parallel to the generator (the generator is the line with the angle theta in the diagram), it will slice either the top cone or the bottom cone into a shape known as a parabola (this has the general form equation Y = aX^2 + b). The degenerate form of this is when a = 0 and therefore Y = b, making it a straight line.

2) what is the degenerate form of an elipse?

This question is not too hard, once you understand what an elipse means. An elipse is the effect of intersecting a flat planar surface with a cone, at an angle greater than the vertex angle, but less than 90 degrees (which would be making a circle). The degenerate form of this is when the plane intersects the double napped cone at the vertex, making a point, or single event. A point is an event--the intersection of an event's past and future is itself.

Tell me that isn't the way we have to post images now...but that's all I could figure out with this new verson of VBulletin

I agree with most of what has been said. I don't like the idea of credit cards; you might as well post your fingerprints and retina prints. There are also those prepaid credit cards that you can buy without giving ID. In the end, making a payment to a site means that you are legally regarded as endorsing all of the content of the site, in some countries, even though you might only find out after joining that the site contains material you disapprove of.

It is not just the anonymity that makes the difference, it is the free access. I don't buy in to the idea that everyone has to surrender their privacy in the name of the common good. Privacy is a very important human need, and I believe we should have a right to it. If the public had to know what every public figure enjoyed doing in the bedroom, I hate to think what kind of people would become politicians.

the underaged users are either discovered and kicked off or they move on to other shinier toys. In the limited amount of time I've been on this site I've seen some folks reprimanded and kicked off the site - just like some of the obnoxious members have lost the privledge to be here.

My suggestion is to require everybody to log in whether they're contributing to the forum or not. Lurking is fine but they should be required to log in.

I don't know about anyone else, but sometimes I am limited on time and quickly go to the site without logging in to check how a topic is going. Making me have to sign in just to read would even further put a strain on that time (like just before I head off to college).
