not necessarily, getting ripped-up doesn't have anything to do with the event horizon itself. A person would indeed be killed due to the forces associated with the differntial in gravity felt by your feet and head (so-called tidal forces). The event horizon distance is a function of the mass of the hole, so it is possible that a sufficiently massive black hole could have very small tidal forces at the event horizon... hence it would be survivable. On the other extreme, less massive black holes could kill you before you even reach the horizon...
sorry, I am a physicist and need to correct a common misconception here... time does not slow down or stop inside the event horizon of a black hole. It only APPEARS to an outside observer that this is the case. If you were to fall into a very massive black hole, you wouldn't even notice anything "different" as you crossed the event horizon and your clock would indeed still "tick". However, someone watching you fall into said hole (from the outside) would see you move slower and slower as you approached the event horizon and would observe your clock to be running "slow". At the instant you hit the event horizon, you would actually appear to "freeze", with no further updates (since you are now inside the horizon and light can not cross the boundary in the outward direction). Hope this helps!

what an amazing coincidence... I am just about to pull the trigger on one of these but I can't decide which to buy, the 250 or the 350. I know the 350 has a hardware decoder as well. How important is this? Someone else mentions a 2% load on the CPU for the 350, anyone have any idea how much of a load the 250 places on the CPU? I plan on using if for timeshifting..thanks!
quick math? The equation for the area of an ellipse is pi*a*b. Hardly more difficult to calculate than the area of a rectanlge. To remember it, it helps to notice that for the special case where a = b, we have a circle, which has the familiar equation A = pi*r^2. So the answer is closer to 118 km^2.

I have heard these stories before. IICR, his early flights were downhill (i.e. not powered takeoffs) being more like a power-assisted glider and were by no means controllable. Read the article, it seems his achievments, while noteworthy, have been exagerated in a somewhat folk-hero manner.

Flat-out wrong. The incidents you mention occurred on Feb 26 and Feb 27 of 1991. Cease-fire negotiations did not begin unitl March 1st and were not accepted until the 3rd of March. In doing this research, I did find some scant references to Iraq agreeing with a Russian plan to withdraw from Kuwait. This is irrelevant since it did not meet all of the US or UN demands, nevermind the fact that Iraq was at war with coalition forces, of which Russia was not a part. This would be somewhat like Nazi Germany agreeing with Italy to end WW2.
I can find no reference that details any proof what-so-ever that there were civilians in the convoy, again just scant claims that that was the case (no pictures of references of course).
As for the Geneva convention, being a military officer, I dare say that I am more educated than you in this matter but again, a simple web search clears things up.
1. Persons taking no active part in the hostilities, including members of armed forces who have laid down their arms and those placed hors de combat by sickness, wounds, detention, or any other cause, shall in all circumstances be treated humanely, without any adverse distinction founded on race, colour, religion or faith, sex, birth or wealth, or any other similar criteria.
The Geneva convention outlaws attacking civilians not engaged in hostilites and outlaws attacking surrendering combatants. Unfortunately, the Geneva Convention is poorly written on this point, as it refers to civilians and surrendering combatants in the same sentance. This leads to the misinterpretation that combatants not currently engaged in combat are somehow protected. There is a tremendous difference between retreat and surrender.
You are clearly some pimply faced punk-ass teenager or possibly college student because it appears you have a learned a revisionist view of history, probably second-hand from some liberal college professor. There is no way you could claim that the US and UK "blessed" Iraq's behavior in the 80's if you had been old enough to watch anything other than Sesame St or Voltron back in those days.
Perhaps you should switch off Fox News, pick up a history book, and ask yourself why it took the Gulf War and this latest War on Terrorism to bring his activities to your attention. For bonus points, find out where else this kind of oppression is going on and how long it's been ignored by the Western world.
blah... blah... blah... more brainwashing by your college professors... Try thinking for yourself sometime... I suggest beginning by watching ALL the news broadcasts (both left and right) and more importantly asking yourself why is it that they present the news differently. Why is emphasis placed on different parts of the same story? That is where you will you will learn more than the actual content of the news...
Bullshit. Iraq was in violation of the terms of the cease-fire at the end of the Gulf War by firing up coalition aircraft nearly every day for the last several years. If shooting at US aircraft is not a reason to go to war in its own right, what is?
War is not pretty. Your so-called highway of death occurred before the end of hostilities. How in any way is it a war crime to allow an army to retreat or regroup (and how do you differentiate between the two?)
The GOP share of the house representatives was in line with their vote in that election.
Simply not true... the current congressional balance is 17-15 in favor of the Democrats in Texas. In the last state-wide election, the Republican governor won with 58% of the vote and a Republican senator won with 55% of the vote (link). The 2000 presidential election was 59.3% in favor of the Republican (granted it was Bush running in his home state). The current districting simply does not represent the new political make-up of Texas. Moreover, some of the "old" districts are as much as 60% minorities a Democrat base, despite the fact that minorities do not represent this portion of the population anywhere in the state. These districts were drawn simply to ensure Democrat seats in congress.
Since the Supreme Court ruled 7 of 9 that a partial hand-recount in only selected counties using different criteria for determing votes was a violation of equal protection under the law.
You miss out one little detail, the judge had thrown out the map previously because it flunked the civil rights issue. So much for your 'less biased sources'.
Don't know what you are referring to here... the census redrawing or the more recent Republican redrawing?
That is not the result of gerrymandering, it is the result of incumbency. Texas has been Democratic for decades
So it is ok to gerrymander as long as it is done by Democrats? Did you ever consider that the Democrats was democratic for so long BECAUSE of gerrymandering? The state as a whole certainly does not reflect the current districting. This is fact, and the Supreme Court has previously ruled that this type of gerrymandering is illegal.
Actually, the Osprey is a fantastic aircraft and I would argue that they took the best features of both types of aircraft when the tilt rotor craft was created (btw, the Osprey is not even close to being the first tilt-rotor... they date back about 30 years, it is just the first military application). Anyway, there have been two mishaps in the V-22 program. One was due to vortex-ring state, a phenomena that was not an engineering issue, but rather a poorly understood aerodynamically phenomena that is more critical in the new field of tilt-rotors compared with helicopters. The second was a combination of a hydraulic failure and a software glitch (which failed to compensate). This type of problem could have affected any aircraft and was by no means unique to a tilt-rotor. When you break new ground, researching a new corner of the aerodynamics, you will undoubtably discover new phenomena.
Actually, if you read other less biased sources than this one, you will see there is an entirely different side to the Texas redistricting story. New district lines were not created after the last census due to partisan disagreements between the politacal parties in Texas. A judge arbitrated the existing boundaries. The Republicans claim that this is only a temporary solution, and that the next state legislature (the current one) would have the opportunity to try again. This is the point that will likely go before the Supreme Court, and IMHO has some grounds to it as the law is quite clear that the legislatures, not the courts, should preform the redistricting. Moreover, the Supreme Court has already ruled that gerrymandering is legal, provided that the states' districts in total reflect a politics of the state. I don't quite remember the numbers (read too lazy to look up) but the Texas legislature had PREVIOUSLY been gerrymandered to benefit the Democrats to the extreme that they now have a 3-4 congressional seat advantage, despite the fact that the state consistently votes overwhelmingly Republican.
what they did in Florida? You mean win the election and then win the automatic recount. They then thwarted a Democratic attempt to deny the people of Florida equal protection under the law when the Supreme Court ruled 7/9 to stop the illegal, Democrat-only county hand recount. Since then, every analysis of the ballots has shown the Bush did indeed win Florida, and that the only way that Gore could have even come close was if the hand recount was allowed to continue in only those few heavily Democratic counties and only then if the most liberal interpretation of "intent to vote" was used.
So please, spare us your consipracy stories and just deal with the fact that Gore lost.
Well direct injection and aerocapture (not aerobraking which still required capture propellant) have their own drawbacks. In the case of direct transfer injection, you are much more constrained by launch windows than if you use a parking orbit. As for aerocapture (my thesis by the way), while there are significant propellant cost savings you now have to have a robust thermal protection system (TPS). Aerocapture has not yet been used on any mission as it is relatively high risk (due in large part to insufficient understanding of the Mars atmosphere and what type of heat loads would be encountered). The closest to aerocaputre that has been accomplished were the direct entries of the Apollo missions. Moreover, aerocapture guidance is still in its infancy (again, point designs have been done but we need a guidance algo that is robust enough to account for huge errors in Mars' atmospheric model). Further complicating matters is the fact that for large (manned spaceflight sized) missions, the heat loads and instantaneous heaing rates really push the limit of what current ablative technologies can sustain.
Don't get me wrong, I think that eventually we will have the technology to stage missions from Mars. However, I think that by the time we overcome some of the human related issues (long zero-g exposure, radiation, psycological, etc...) we will likely have made other advances that mitigate the benefit of launching from Mars over simply staging from Earth (i.e. cheaper access to space here at home).
I am not saying that Zubrin has misled you, and I never finished reading my copies of his books. He does an excellent job of pointing out the current deficiencies with our current technologies and policies, but I think he is overly optimistic in the alternatives that he suggests.
