Straight-and-level flight might be automated-ish, but most landings are still done by hand, and takeoff is in fact much *harder* than landing. See the last two questions and answers in this article: http://www.salon.com/technology/ask_the_pilot/2010/10/08/question_and_answer

Technically true, but look beyond the formulae for a brief moment and look at what they're *doing* and you'll see the way out: his mechanism for computing [x,y,z]^n is to convert it to spherical coordinates [r,theta,phi], then do something similar to complex exponentiation - [r^n,theta*n,phi*n] - then convert that back to rectangular coordinates. So rectangular [0,0,1] becomes polar [1,0,0], which squares to polar [1,0,0].

Makes sense as long as you think about it a little, but not too much.

"Bathtime, kiddo!"

Preach it, brother. The only reason the F-lock key isn't winning this poll in a landslide is that most people aren't unfortunate enough to have one.

Oh, and you were doing so well up to that point. A cubic meter is 1,000 liters; filled with water it would have a mass of 1,000 kilograms, or one metric ton. For a single liter, you want a cubic decimeter.

But thanks for playing, anyway.

Dude. You are my hero. That just became my project for tomorrow. Sure, I'll spend a lot of time on it... but if it works, no one will ever know!

Door (closed, and heavy enough to mask most noises) on my left, window on my right, monitor and speakers in front of me. Eat it, cube-dwellers!

Umm... if the gerbils are cannibalistic, wouldn't that mean they would eat each other? Not a terribly fear-inducing defense, I'm afraid.

If I beat you up and leave you for dead, that's one victim.

If I beat you up and leave you for dead because I don't like your hair color, and it's known that I belong to a large group of similarly-minded people, then not only have I victimized you, but everyone who has your same hair color is now going to be looking over their shoulders, in fear that one of my compatriots is after them next.

That's why "hate crimes" deserve special punishment - because they have the intent and effect of victimizing not just one or two or a few people, but a whole group. It's a whole new level of unacceptability.
