But they don't have to get approval until AFTER they have already done the spying. That is a huge difference. It means that they can just look at whatever they want without cause. If they find nothing, they can just cite national security and give no real reason to justify it. If they find that you email a lot to an old friend who moved to Somalia, suddenly you are on no-fly lists, or worse. Totally unacceptable intrusion on our personal rights as citizens.
The Patriot Act was written long before 9/11, and was just setting on a desk waiting for a proper time to introduce it. In the mess after 9/11 it was introduced and easily passed. The people who wrote it didn't know that an attack was going to come along in several months. They just wanted to be able to spy on whomever they want without legal recourse.
I doubt that would work. I'm pretty sure that even if you locked the steering wheel straight ahead, the car would still end up spinning out once it gets much above 100. The wind and variations in the lake surface would destabilize it to much.
Because the car isn't already equipped to maintain a proper air-fuel mixture right? Oh wait, yes it is. In fact if it didn't carefully monitor and adjust the air-fuel mixture, the turbochargers would blow the engine in a heartbeat, even in normal driving conditions.
The trains are late mostly because they have to share the same tracks as freight trains, which don't really care if the Amtrak trains are late. Note that Amtrak leases access to the tracks, which are actually owned by the freight companies from the most part.
Yes, the clock is constant within it's own frame of reference. However, like everything else, that frame of reference is affected by time dilation.
Since your body has mass, it's presence near the clock will cause the clock to slow slightly in comparison to an identical clock placed farther away from you.
Is the time as clocked by the motion of the earth the same as clock by a vibrating atom?
I would say no, because time varies depending on how deep in the gravity well you happen to be. The earth itself is experiencing different rates to time depending on altitude/depth, and the density of nearby rock, etc. So the only time that the earth clocks would be an average time.
Makes me wonder how much of the current of the liquid portion of the earths core is due to the difference of the passage of time between the crust and the core. I know the difference is pretty minor, but it must contribute something.
You presume that they are talking about creating intelligent life, when in reality that are almost certainly talking about bacteria. All that would be necessary to prevent the kill switch from being bred out would be to make it a part of a vital gene. This way, if the gene is modified, then the organism is already going to be non-viable, so it wouldn't matter if the kill switch was broken.
Um... sorry to burst your bubble but nothing boils at absolute zero. And the ambient temperature of space is pretty warm, actually. (in terms of the temperature of the sparse distribution of particles out there)
The reason you would freeze in space (besides boiling, which is an endothermic process) is because you radiate energy via infrared light faster than you acquire it via bumping into hot space particles.
I wasn't suggesting that Mars cannot theoretically support a thick atmosphere. Clearly Titan has a thick atmosphere and is much less massive than Mars.
Rather I suggested that absent a strong magnetosphere, the combined mass of Mars and a thicker atmosphere is below the threshold such that gravity could prevent significant loss of said atmosphere over the last few billion years.
Either that, or Venus is currently losing atmosphere at a similar rate to Mars and simply had acquired a much thicker atmosphere at the time the solar system formed.
It took billions of years for it's atmosphere to get blown away. I'm pretty sure that we could deal with a rate of loss that is that low, at least for many millions of years.
This experiment just shows that the lichen was able to survive long term exposure to space. It doesn't say anything about growth, which is what you would need in order to do any sort of terraforming. It would be nice if they would give a bit more detail on the findings.
The problem is that it would need to stay airborne (the surface is hot enough to melt lead) and be very resistant to low pH (sulfuric acid rain is kind of a bummer).
Isn't sight for the blind already getting close? (ok, last I heard it was B/W only and the resolution was ridiculously low, but it was still a brain machine interface)
Once in a while I notice that the tempo of a song playing on the radio seems to be off. Faster or slower than I remember it. My theory has been that my mind is operating slower or faster, repectively, than usual when this happens, or at least the part of my brain the processes music is.

No, he is just saying that life doesn't necessarily need a solar source of energy, as the deep sea vent species demonstrate.
How you use that to jump to your conclusion that he thinks life arose twice, I don't know.

That it can drive a car does not mean that it is in any way intelligent.
It will have a map. Perhaps you should RTFA.

Ask the same question multiple times. Including the negative of the question.
Why? You think that no matter how fast you add atmosphere, it will be ripped away just as fast?

Well done sir.

As though you've never bumped the same letter twice while typing. Asshole.

The gravity of mars is significantly weaker. I would think that this would make it more prone to loose atmosphere.

Actually, I'm talking about a different approach, one that actually uses a set of electrodes in contact with the brain.
