Exactly. That's why the biggest creature that exists and has ever existed is the elephant, because dinosaurs would've been crushed by their own weight.
I think you slighly misunderstand Heisenberg. As I see it, the relevant equation is delta E*delta t > h_bar/2, so if they increase the frequency enough, they're also gonna need to increase the energy used.
You do realize that the US was running around meddling in world politics precisely because we didn't want the USSR to be the only ones meddling, don't you.
You're completely right. Depression isn't caused by poor personal choices with regards to foods and mindset. It is a horrible affliction that can only be cured by expensive drugs and more expensive therapy. The strength of those who struggle though life with such a horrible disease that they have no control over pales such those cowardly cancer patients, who also had absolutely no control over their disease.
US schools are incredibly overfunded for the level of achievement they provide (on average). Increasing funding because something isn't working is nearly always the worst solution to a problem. The problem is that the funding is not being provided where it's needed. If you look at Average spending per pupil and SAT scores, there is a high correlation to the best funded with the best ranking. Ideally, the best solution would be to not make it acceptable/cool to not do well in math/science, but pragmatically, school districts across the country need to be provided with closer to the same level of funding.
Ok, I see the problem is the ambuiguous use of velocity without specifying translational or rotational. This leaves me with no objection to having a tether with the tip moving at 1km/s, it'll just take however long an ion drive needs to accelerate the cargo to orbit velocity and then deaccelerate. However, when the tether makes the rendezvous with the aircraft, it looses some translational momentum (keeping it in orbit), so the tether mass must be signifigantly higher then the aircraft to prevent a rather problematic deorbit.
So my only real objections are the sheer mass of the tether, and the power requirements. Otherwise, I agree that it's a much more feasible idea than the space elevator.
Are you so blinded by fanboyism for tethers that you did not comprehend "If you disagree with these conculsions, please supply your own calculations and not just meaningless words." Give some evidence why a 2km/s aircraft and tether would work, keeping in mind the x15 is the only plane to have reached that speed, and it's much easier to reach 1km/s than go from 1km/s to 2km/s. As for your ideas about rendezvous, you still need to be going 7.73km/s to be in orbit, and if that speed isn't from your 2km/s rocketplane/scramjet/flying carpet, it's coming from the tether, which means that you're dealing with 100's of Gs - the relative velocity can only be 0 if you're going 7.73km/s, orbit isn't so much a question of height, as speed. If you're going too slow for a given height, you'll deorbit.
NASA must've really screwed up to have the Jupiter Icy Moons Orbiter orbiting earth instead of sending it off to Jupiter.
Assuming that your SpaceShipOne can reach 100km at 1km/s, with your skyhook CG at 200km with a R of 100km to reach orbit at 300km. That means your acceleration upon reaching the skyhook would be 453 Gs, and you'd be trying to hit a target (with extremely well predicted motion, though) moving 6.73 km/s. As for the ion drive, wiki says that to accelerate 1000kg by 3000m/s, it'd require 77.5 GJ, so if you wanted to lift 1000kg/day, you'd need about a 150*150 m solar array (this is quite low, since I didn't feel like calculating a delta V of 6730m/s, and 1/2 ton/day is quite a low figure, as well as the fact that I assumed perfect energy collection, it'd probably be more on the order of a 500 -> 1km on a side array (for obvious reasons, nuclear is not a viable option)).
To recap, google says the fastest missile travels 1500m/s, while most fighters can't reach over 1000m/s, more typically 700->800m/s, which is radically different than this skyhook scenario, to get the acceleration down to 10Gs requires you to travel at 6.73km/s, making a skyhook practically useless, or employing some massive dampening system, which does not seem conceivable, and finally, the energy requirements are far beyond what is practical in the near future (50 years).
If you disagree with these conculsions, please supply your own calculations and not just meaningless words.
That still leaves (maybe greater) problem of having your SpaceShipOne making a rendezvous with your skyhook. You've got a probably millisecond window of opportunity, not to mention the G forces when it gets picked up would require massive dampening. And you would still need expensive rocket refuelled to keep the thing turning.
The PowerPC is an inferior processor to the PM, both raw speed and speed/watt. Futhermore, both the PM and PowerPC are RISC, only the PM has a translation unit to internal micro-ops that is becoming more negligable as die real estate is used for cache and more functional units or dual core. As for some "aesthetic" appeal of RISC vs CISC assembly, asm is asm, and since you can use SSEs on Pentiums in C, whereas Altivec *requires* you to use asm, it would seem that even the ISA is of a poor design.
Intel has made a processor that is both faster, better designed, and more work/watt, as well as being able to supply them in quantity reliably. Go take a graduate course in Computer Architecture or at the least read and understand H & P before you spout some kneejerk emotional reaction to your beloved Apple using the same processor as us unwashed masses.
IPA is not poisonous, at least in the sense methanol is, since the body can't oxidize it past acetone, and its that's much nicer than formaldehyde and formic acid.
Imagine the universe as a flat rubber sheet. If you stretch the sheet uniformly, then points further apart "move" faster apart than points closer together. All the quote in question is saying is that at the some points in the universe, the fabric (calico IIRC, though there is a rival theory with tweed) is moving apart faster than C, nothing is really "moving" per se.
You do realize that fallout happens because of nuclear explosions in the atmosphere, don't you? The US and Soviets tested 1000s of nukes below ground, like these bunker busters, which doesn't produce fallout.
This is in addition to the economic dependence on foreign oil, environmental impact of pumping massive amount of CO2 into the air, and the health problems caused by these supposedly freedom loving people driving. The only "freedom" given by the car is being free to spend hours in gridlock because you choose to live far away enough from your job and think public transportation is for commoners. In very few instances is the car anything more than a glorified, highly visible status symbol.
As for it providing a life away from home and work, how exactly is it doing that, seeing as how nearly everywhere people drive to is a popular area, not Big Sur. Driving instead of taking the bus isn't freedom, it's laziness.
That would certainly explain why we're bitches to foreign oil and pumping massive amount of CO2 into the air without any clear ideas of what will happen besides weather gets more extreme. The car culture was created by the white flight from cities and creation of suburbs where people want big lots and big suvs to hide their small minds and dicks.
Yes, the existance of gravity is clear, as is the existance of diverse species. Newton and Einstein gave theories which could be tested and disproved, and we shown to be "correct" (in a scientific sense), while Neo-Darwinism have given theories which can be disproven, and all manners of valid and invalid arguements have failed, but ID has no clear disproof, unless you count the numerous flaws in creatures to be disproof of "intelligent" design, and as such cannot be included in the framework of science, regardless of its "truth".
I searched xxx.lanl.gov for zero point energy big bang and come up with nothing, google only gives a bunch of kook free energy websites, got any links/paper names that have cosmologists abusing ZPE (and preferably pointing out where the problem is)?
>>zero-point energy This exists too.
>Sure, and any astronomical or cosmological event that demands an unlimited energy supply can tap into it at need.
You misunderstand the nature of zero point energy, which was thought of by physicists before NASA existed. ZPE is like having a gas tank where the pump can't reach the last gallon. The tank still has energy, but it can't be used for anything, and so you car it at its lowest energy state. ZPE is only a source of energy to kooks trying to make perpetual motion machines or free energy.

Repeatedly, in The Detroit News and in other media, the term "white flight" was used to describe the exodus that led to the city's white population decline from 1,545,847 in 1950 to 116,599 today, or 12.3 percent of Detroit's current population., which backs up White flight
"The loss of pedestrian-scale villages caused a loss of community connection. People no longer know their neighbors and rarely walk unless they place a high value on exercise."
"Although a few expensive items, such as pianos and sewing machines, had been sold on time before 1920, it was installment sales of automobiles during the twenties that established the purchasing of expensive consumer goods on credit as a middle-class habit and a mainstay of the American economy."
