Well, he seems to have all the stereotypical gestures and sounds bites of a career politician down pat.

I don't think his mother gave birth to him at all, I think he was probably just assembled in Alabama with spare parts from dead republicans. Coulter was probably so excited about the project he donated his penis.

New blood is new blood, but it's pretty sad when both your party and your country are in a state of crisis and free fall that you turn to a 14 year old for guidance and ideas; that goes for any political party that would be so desperate to retain some amount of its power.

If he actually turns out to be the one that "saves" the republican party, I'll eat my hat.

You'll be wishing for the Bush Years again when inflation hits.

Do you think China and other countries will start dumping dollar assets? I'm starting to wonder if they see it as a viable alternative.
America is a large part of the world's consumption. I don't think China "needs" US consumption to stay afloat, but it would sure as hell take a big chunk out of their economy if they dumped their dollars and sent the US currency into free fall. China may fear the unhappiness and controllability of their own populace in that case.
That's just a guess though, I don't know what they're thinking.


I read an article in Bloomberg back in October I believe that the US had worked out some kind of agreement with Japan and China (the largest holders of our debt) that they would not sell dollars. October seems like decades ago though, things could have changed by then.

The last treasury auction last week didn't go so well. An anonymous buyer, most likely the Fed, came in at the last minute and saved the day. Not a good sign considering that we haven't even begun getting to Obama's spending plans yet.

He talks about a navigational GPS system, which makes it so you do None of the flying, you sit there and play video games or read or something and the car does the rest of the work.

Near the end he was also talking about how it comes equipped with parachutes, not sure if that means ejection seat, the car itself deploys the chutes to land safely, or if you're supposed to strap in during a free fall.

And as for the shield technology, it's an M class vehicle on roads, so it goes by motorcycle safety rules while on the ground, unless you're talking about flying in the cities again and I refer to the part where he talks about the designated launch sites.

Essentially he was talking about what I figured, drive to a launch site, they point you in the right direction, and say "Have a nice flight" and the computer takes over.

With an entire system in place much like flight navigation this wouldn't be an issue, the car can fly up to 25,000 feet and with a GPS they'll be able to track it and make corrections as they go along.

I'm actually very excited at this video.

NIST has a comprehensive report detailing how this particular structure collapsed, and how come others that have either been engulfed in flames for DAYS, OR also hit by a plane, did not collapse in the same manner.

It has to do with the way the floors were constructed around a central pillar.

Trusses linked to the outer frame, and the inner core with a few simple angle clips to hold and share the load, with no free-standing pillars like conventional towers. This gave the floors much much more open floor space than any other tower out there...with obvious advantages.

Take some of the clips out of one floor thats hooked into the outer shell, and you have to share the load of the floor on the rest of the clips.

Shock load the clips and you stress them to a point where they cant hold as much weight prior to a collapse as they used to.

Strip the fire-proofing material off the steel that was rated to handle fires much much hotter than jet fuel could possibly provide, expose said steel to a mix of noxious gasses (created by burning old office equipment) that destroyed basic bonds holding the alloys in the steel together and you turn said steel into iron...drastically lowering its strength potential.

Heat the iron up, she melts...more clips fail, floor pancakes onto one below it. The one below is shock loaded and snaps instantly.....domino effect ensues, tower collapses into its own footprint at close to free-fall.

And yes, concrete can vaporise if you provide enough force.

Other towers either hit by a plane, or had been exposed to much hotter fires for far longer, had drastically different internal designs. They had a series of cubes connecting to one another, essentially an intricate pattern of concrete covered steel beams criss-crossing their way through the entire structure.

Take one beam out (either by fire or collision)...big whoop, theres 300 others to do its job. Not so with twin towers, the clips holding the trusses were limited, and a significant portion of them on the central impact floor were taken out in the collision.

Yeah, "TFK" seems pretty sure of him/herself,perhaps justifiably, but there are several dissenting opinions as well...

#1 ...At least, that's how this layman understands it.
#8...I can help you. The free fall proves that WTC 7 was a controlled demolition. Science has proved that.
#40...Actually, I have never read such an awful report as the NIST WTC7 report. Pure propaganda! The structural analysis after initial failure is simply not correct. (this user claimed to create his or her own finite element analysis model, so probably knows a thing or two).

He implies that his margin of error is only 1% because his final answer of 9.88m/s/s is within 1% of the known acceleration due to gravity. This is faulty logic. The known value of acceleration due to gravity plays no part in the calculation of the error of his results.

His errors will be introduced by the distance measurements that he is taking in both his calibration measurements and the location of the roof in each frame.

He states that the known width of the building is 100m. Is this the width when looking straight on? Is this video looking at the building straight on? If not then he is overestimating the width of the building in the video.

He is using the height of the 29th floor and the height of the roof for another distance calibration. There are a variety of ways including perspective and the grainy, low resolution of the images that could lead to him overestimate the height of the building.

Any overestimates in his distance calibrations will result in an overestimation of the distance moved between each frame of animation, which in turn overestimates the velocity of the measured point on the roof, which in turn results in an overestimation of the acceleration.

His final answer of 9.88m/s/s is actually faster than free-fall! So he must be overestimating his distances somewhere. The question is by how much?

The question posed was...

"Any number of competent measurements using a variety of methods indicate the northwest corner of WTC 7 fell with an acceleration within a few percent of the acceleration of gravity. Yet your report contradicts this, claiming 40% slower than freefall based on a single data point. How can such a public, visible, easily measurable quantity be set aside?"

"Could you repeat the question?"

[the question is repeated by the moderator, leaving out the word, "competent" as well as the last sentence]

"Well...um...the...first of all gravity...um...gravity is the loading function that applies to the structure...um...at...um...applies....to every body...every...uh...on...all bodies on...ah...on...um... this particular...on this planet not just...um...uh...in ground zero...um...the...uh...the analysis shows a difference in time between a free fall time, a free fall time would be an object that has no...uh... structural components below it. And if you look at the analysis of the video it shows that the time it takes for the...17...uh...for the roof line of the video to collapse down the 17 floors that you can actually see in the video below which you can't see anything in the video is about...uh... 3.9 seconds. What the analysis shows...and...uh...the structural analysis shows, the collapse analysis shows that same time that it took for the structural model to come down from the roof line all the way for those 17 floors to disappear is...um... 5.4 seconds. It's...uh..., about one point...uh...five seconds or roughly 40% more time for that free fall to happen. And that is not at all unusual because there was structural resistance that was provided in this particular case. And you had...you had a sequence of structural failures that had to take place and everything was not instantaneous."

could you please explain or tell me where I can see explained, why it would not just go into an elliptical orbit instead? Keep in mind you are in a space suit outside the spacestation and can only throw about 30 miles per hour or so. What about if you throw an object straight "up" while in orbit? My guess is the result would be the same.

When an object is in orbit, it is already in free-fall, but the centripetal force going up is equaled by the force of gravity going down. If you chuck something down, it will continue that way until it hits the ground.

some day I'd like to be hurtling through the vacuum of space and just full-on chuck something down at Earth.


I have a question for the physicists - what would happen to an object thrown perpendicular to your orbit down toward earth? Disregard atmospheric drag. After one orbit, would that object come back up towards you as fast as you chucked it?

This needs to be a level in a new FPS. Or a game in itself!!


There's a level in "Jedi Knight: Dark Forces II" where you're on a ship that is plummeting to the surface of the planet and you need to find a way to get off it. As it falls, it's rolling and twisting which means the level is basically rotating as you're trying to escape. Sometimes you're running on the walls, sometimes on the ceiling, sometimes you wind up free-falling down the hallways. Oh, and stormtroopers are still shooting at you as you try to escape. And stuff is sliding around too, so you have to avoid being crushed. It was bloody brilliant. I still contend that game had the best level design of all time.

I can't stand how long these rides just sit at the top.

Really? That's the scariest part of the ride. The slow ascent then the anxiety that eats you alive as you look at the earth's horizon anticipating. waiting. dying a little inside. breath weakening. until finally... You scream like a little girl. (Or at least I did my one time on such a ride.)

This is just another Mortal Kombat game with DC characters in it. But i love how awesome it looks, close fighting and free fall fighting look real intense. Special attacks look good. It's funny how superman's attacks look like he's just brawling. I really want this game!
