  1. Hello, I live in Muslim country and i have to say something about that. Actually, in educated side of our country, people are informed about birth control methods . However, in uneducated side , it is beyond women's power. Womens doesn't have right to speak, so that all control is belonged to men. Our goverment is handing out preservatives to prevent this problem , but I think nobody use them. Even,a few years ago, I heard some news about that. Some kids were using preservatives like balloon. On the other hand, even if they were educated, probably they don't do something. They aims to having much kids, they use them like soliders. they protect themselves and make money through their kids. Nobody doesn't care life standards of kids, especially girls. These people do that to live. Goverment, police or any defensive force can't prevent them, because they are not enough to stop hunger , terror and unemployment. In my opinion, education can be part of the solution , but this is not enough. It is releated with economy and politic situation of country. Solution is being social democracy. As for me, this is not about religion. In our country, nobody against abortion, it is totally about management.

  2. If you're converting from m^2 to cm^2 you need to divide by 100 twice (because 1 m^2 is 100*100 cm^2 = 10000 cm^2). e.g. 1.9*10^9 N/m^2 is 1.9*10^5 N/cm^2...

  3. I'd like to think so (in an ideal world) but Isreal is looking for excuses, not reconciliation.

  6. OK, got it... I think 1/3 of oxygen means also 1/3 of nitrogen. Compressing brings up the density of both to a tolerable level as in ~3000 ft. My misconception may had been believing that only oxygen was less dense at altitude, as if it was a stratified column of air from hearing "There is less oxygen at high altitude" Well, yes, but there is less nitrogen too, actually being "There is less air at high altitude" -There is less O2 because the whole air is less dense.- That is why compressing takes care of it.

  7. As I said in my previous post. Relativity makes no such claim when it comes to what an observer will visually see. This is a straw-man argument based on a misrepresentation of Relativity. To explain the difference between what the observer would visually see vs. what he is conclude is happening, we'll use some space-time diagrams. First consider two clocks separated by some distance and stationary with respect to each other. The blue line is our "observed" clock and the green line is our "observing" clock. The scale is such that light, shown as the yellow lines, is drawn at a 45 degree angle. Thus our observer will see light that left the blue clock when it read 1 arrive when his clock reads sometime after 3, and he will see the blue clock read 1 at that time. He also will see the light that left the blue clock when it read 2 arrive sometime after his clock reads 4. However, this does not mean that he will think or conclude that what he sees actually represents what time it is for the blue clock at those moments. That would be shown by the black horizontal lines, which shows that when the green observer sees the blue clock read 1, he knows that it actually reads the same as his own, or somewhat after 3, and when he sees the blue clock read 2, it actually at that moment reads somewhat after 4. Now let's add a third clock, one that is moving at 0.6c relative to the both clocks so that it and the blue clock are closing in on each other. This will be the red line in the following diagram. The light that left the red clock when it read 1 still arrives at the blue clock when the blue clock reads somewhat after 3. But the light that left when it read 2, arrives before the blue clock reads 4. The blue clock observer will in fact see the red clock ticking at a rate twice as fast as his own. But again he will not conclude that this means that this represents what time it actually is at the blue clock. When he sees the blue clock read 1 he will conclude that it reads a bit before 3 at that moment and when he sees it read 2, he will conclude that reads something before 3.5 at that moment, as shown by the black lines. He knows that the light carrying the image of the blue clock reading 2 left the blue clock when it was closer to him than the light carrying the image of it reading 1 left the blue clock. His has to account for this when determining when exactly that light left according to his own clock. As the black line from his clock reading 2 shows, the red clock didn't actually read 2 until sometime after his clock read 2. Thus after accounting for the time it took for the light from the red clock to reach him, he will conclude that the red clock is ticking slower than his own. This is time dilation. Now add yet another clock, this time so that it and the observer are receding from each other, as shown by the light blue line. Again the light leaving when it reads 1 arrives at the green observer when the green clock reads after 3. But the light leaving it when it reads 2 doesn't arrive until the green clock read after 5. The green observer will see the blue clock ticking at 1/2 the rate of his own. But this time, the light blue clock is further from the green when it reads 2 than it was when it read 1, and when the green observer takes this into account, it will turn out that when compared to his own clock, the light blue clock is ticking slower than his own, and by the same rate as he concluded that the red clock is ticking slow. The light blue clock exhibits the same time dilation as the red clock. This is what Relativity says is happening in the real universe, and this is not you you are trying to claim it says ( that an observer will always see a clock as running slow). If you are going to argue against a theory, you have to argue against the actual theory rather than some imagined version of your own creation.
