6000 m/s = 13400 mph. That makes the energy a factor of 11 too large.

Yes - the profits would go to the buyer or seller (I don't see the exchange's profits changing, but maybe they would), but they are the only ones *providing* something. The HFT is just a middleman. I'm OK with him not making anything since he's not bringing anything to the party.

Will "Nanorod" describe something men want associated with their junk?

B) what exactly does lack of mass have to do with anything? Light (which can't escape either) is a massless boson.

Could someone mod this up to 11?

The police have nothing to do with libel or slander. Google "Tort vs Crime". And if the police have ever restrained anyone they suspected was going to yell fire in a theater, I'd love to see the case history.

"Go look up crime statistics and you will find that the number of crimes committed with machine guns is either zero every year or in single digits."
So it seems that the idea that guns can't be effectively regulated (if we outlaw guns, only criminals will have them) doesn't apply to machine guns. Maybe we should regulate all guns the same way machine guns are regulated.

I thought he'd only use it inside a walled garden.

The attachment to guns is not rational. Whenever someone starts that nonsense about how you can kill someone with a knife, a rock, etc., so we'll have to get rid of those if we get rid of guns, I would say this: Imagine you're at a crowded basketball game. Some nut runs onto the court carrying a) an automatic rifle b) a rock or knife. What will your reaction be in each case? Do you even bother to get out of your seat if you're 15 feet away in case b? How many people will be killed by the rock or knife before the person is subdued? If 2 people rush the rock-holder, he's pretty much going to be stopped.

I'd be (mildly) interested to know where dipshits like this come from. I don't understand the whole conspiracy theory mindset - if it were something that happened in the era before cameras, maybe they could construct a reasonable alternative explanation, but it (the second one into the WTC) happened live on the morning news! How many people in NYC actually saw the second one (not via TV) as it happened? I wouldn't be surprised to hear it was a million, since the first one happening kind of called people's attention to the area. I guess this kind of clown just needs to feel like he's somehow one of the only ones who has been able to find "the truth" and is therefore smart.Sad.

Do a little research of your own and come back with some numbers on how many tenured full professors make $200k a year. Tenure is nice (I've got it), but don't kid yourself that it comes with a giant salary. That's one of the justifications for it - you're not paying people a fortune, so you have to add something like tenure to sweeten the deal.

The "college industrial complex"? Really? Because it's such an easy life (that you know absolutely nothing about), right? Tell you what - go knock out a PhD and a few years as a postdoc or temp faculty while you hunt for a tenure-track job and then bust your hump teaching, researching, and doing service for 6 more years. At that point, you too can coast into making 7 figures and only teaching 45 seconds per semester with the rest done by graduate students. Oh wait - that's bullshit.
