I actually worked on a relativity simulator like this a couple years ago: http://www.refsmmat.com/jsphys/relativity/relativity.html
Different idea, though. Instead of letting the user construct a Minkowski diagram, it has a set of built-in scenarios (common teaching examples). It can display...
Problem is that bolding stuff is done on the the server side. You could implement your scheme as a Greasemonkey script or something for Firefox. That wouldn't help when you hit the button to search for new posts though.
vBulletin provides the option of marking threads as read based on whether you've visited since the post was made (which ignores the fact that you might not have read it) or based on actually marking threads as read as you read them. It defaults to the first option because the second is...
agh!
I don't see how you can hate cats, as long as it's the right cat. Mine never attacks you, runs away, (but she does stay out at night occaisonally) and is quite lovable. This is a stray I picked up. So obviously some cats are better than others, like dogs, where you can have the dumbest...
Geometry for one, because shape is important. Things like right angles entirely ruin it. The surface has to be designed to almost always reflect the transmission away from the transmitter/reciever.
Only in 0 visibility. Pilots don't really trust the autopilot, all it does in landing is present ILS information, like where the runway is and at what angle, altitude, and that.
The cannibals one? Ask them what the other would say (on how to get to the safe city)! That would always be a lie, so you know how to get to the safe city.
Me, I'd invent a device that keeps them from hearing my thoughts. After spending long months in solitude so they won't be there to hear me swear at them.
Then I'd sell my device and make millions.
Odd... I'm sure it can be explained, though. I mean, SETI (and earlier projects like it) has been going for something like 50 (?) years, and all of the odd signals can be explained by quasars, human interaction, and other natural devices.
But if it is some aliens, it really makes you wonder...
Exactly. The hijackers would just wait until you are over the target city, and then attempt to hijack the plane. The parachute foils their attempt, but the plane still crashes into a populated city, killing many.
