... that most people would want somebody else to fix their computer? Personally, I don't, and that is why I use linux. But in this case you have to think of the millions of people using computers that don't really know the difference between their computer and Windows. These people will never apply a security patch, let alone even know how to upgrade. Microsoft is crossing some lines here, but they will make it easier for people to use the newest version of the operating system (will all the security enhancements from what they've been saying).
This is, of course, if they don't blow it and release a buggy OS onto 500,000 computers by accident.
Not true. For massless particles, the momentum is Planck's constant divided by the wavelength.
Particles at the speed can be considered as having all their mass converted into energy.
No exactly. Mass is a measure of internal energy. Massless particals are massless because they have no internal energy. You could argue that a photon can be produced from an electron, converting its mass to energy, but that reaction only happens when it hits a positron, so it doesn't really count. An electron won't decompose spontaneously.
The point that I was trying to make is that Heisenberg's uncertainty principle is not related to mass and velocity directly. It is related to the momentum of an object, which in some cases is mass times velocity times gamma (where gamma is a high speed correction factor / a function of the velocity).
Heisenbergs uncertainy principle states that the measurement of velocity and position of a particle can only be known within a certain limit. It is possible to know one parameter very preceise at the expence of the other parameter. To be more exact
Planck's constant = position * velocity * mass of particle
Heisenberg's uncertainty principle is related to momenta, not velocity and mass. Particles travelling the speed of light have no mass, but still have momenta, and thus are constrained by the uncertainty principle. A massive particle has a momentum of mass * velocity, but only at speeds small compared to that of light.

These people were probably poor. They were in the forest gathering wood and they found something that would keep them warm. They weren't stupid, it's just that they didn't know what it was. If you're living in an underdeveloped part of the world, you take your warmth during winter where you can find it.

The creationists don't disagree that our methods show that the bush is 11,000 years old. They simply think that when their god created the universe that it created it in such a way that things in it would appear to be different ages. There's no way that I know of arguing against this because you can't logically prove that everything is what it appears to be. On the other hand, you can't prove that it is true. Once again we find that the argument has turned to faith vs. rational thought. It's really a preference from there on.
You'd be surprised by how many people share the same beliefs with this kid. These days it seems like the "counterculture" is just as propaganda-controlled as the mainstream culture. On one hand, you have corporate culture: Dawson's Creek, Friends, Cosmo, etc. On the other, you have the Socialist Vaangard, Raise the Fist, and other groups like this that speak of the evils of Bush and the holocaust in Palastine.
When did our counterculture get culture-jammed? I thought the point of counterculture was to think rationally and try to find solutions. Now it's just a bunch of smokers complaining that the Man and the Corporations are out to get them. It's really sad; this prevents people who have rational reasons for disliking current US policy from getting any respect or decent media coverage.
I am strongly convinced that a majority of Americans are completely braindead.
Braindead or were never taught how to think? The brain is like a muscle in the sense that if you don't use it, it gets weak. Unfortunately, most children, even in the US, are not taught how to flex their brains.
Sadly, it's not that funny. Did anybody read his recent state of the union address? He basically rehashed all the propaganda we've beeb told in the past year.
Thousands of dangerous killers, schooled in the methods of murder, often supported by outlaw regimes, are now spread throughout the world like ticking time bombs - set to go off without warning.

his is one of the major problems inherent in democracy: Nobody (apart from the Emperor himself) knows how long the Emperor of China's nose is, but everyone has an opinion.
Actually, I disagree. It's only a problem if we argue over every decision. We fix this kind of problem by delagating informed people to make the decisions for us. That's why NASA has a board of directors (or some such thing).

Mars does have a much weaker gravitational field. I would guess that it would make it easier to stay up once you were up. I don't know anything about aerodynamics, but I'd think the gravitational constant would figure in somewhere, making the ratio Mars/Earth Speed Needed smaller.

This is a common misperception. Vinal is not good quality. It has much less data/track than even a 128kbit mp3. It's considered to be better because it has a warmer and more authentic sound. This better sound is a byprodut of the medium and has nothing to do with the recorded sound.

Bohr didn't believe an atomic bomb was possible.
In this draft of a letter to Heisenberg, Bohr said that he had known about the possibility of a bomb for about three years.
Who else thought this was really sad? I makes me sick to see physics caught up in such horrible politics.
