  1. I didn't realise Imatfaal had already posted about it and missed it...I was away yesterday. Sorry about that.
  2. The evidence for Einstein's GR just keeps piling up: A curved signature in the cosmic microwave background light provides proof of inflation and spacetime ripples Proof of gravitational waves created by cosmic inflation is shown here in this image of the cosmic microwave background radiation collected by the BICEP2 experiment at the South Pole. The proof comes in the form of a signature called B-mode polarization, a curling of the orientation, or polarization, of the light, denoted by the black lines on the image. The color indicates small temperature fluctuations in the cosmic microwave background that correspond to density fluctuations in the early universe. BICEP2 Collaboration Physicists have found a long-predicted twist in light from the big bang that represents the first image of ripples in the universe called gravitational waves, researchers announced today. The finding is direct proof of the theory of inflation, the idea that the universe expanded extremely quickly in the first fraction of a nanosecond after it was born. What’s more, the signal is coming through much more strongly than expected, ruling out a large class of inflation models and potentially pointing the way toward new theories of physics, experts say. http://www.scientificamerican.com/article/gravity-waves-cmb-b-mode-polarization/
  3. If all devices could eventually be charged by induction there won't be any need for physical interface standards.
  4. If you made it seem like a direct quote but the content or spirit was distorted beyond the author's intent that would be misleading and can't be good form. Also, I think you need to preface or follow your version of what someone said in such a way that the reader is clearly informed that it is paraphrased. On topic: There seems to be two ways to get the cursor out of the quote box after editing depending on what mood the software is in. Normally I can just click it outside the box and there the cursor will be but sometimes it it gets stuck. If you take it to the end of the quote after editing it then double-tap the enter button it should be outside the box.
  5. You may well be right but my question was from a learning perspective not argumentative. Would being dark-skinned in a UV-poor environment be a significant enough disadvantage to cause a change in a population with that property in five millennia?.
  6. I'm sure we've discussed this before but that relates to the observable universe and you could have an infinite number of adjacent observable universes, so, it's not illogical for there to be an infinite universe as well without invoking an infinite rate of expansion for it to be that way. Does that make sense?
  7. Could covering up their bodies due to cooler cloudier climates have facilitated the selection of lighter skin in such a short time?
  8. In the beginning, i think, democracy has to be fought for in the literal physical sense if that is the overwhelming popular feeling in Ukraine ...forcing square pegs (pro-Russians) through round holes just like the pro-Russian faction are trying to do now to pro-democrats. The pro-Russian government, by locking the door behind them and securing their position, are seriously cheating and I sympathise/empathise that Ukrainian pro-democrats feel they must use any means, including violence, to avoid more decades of communist-type autocratic oppression.
  9. What's your download speed? Use this: http://www.speedtest.net/ Externet. Zorin is great but it's too heavy on resources ...it's about equivalent to W7...needs at least a gig ram.
  10. I might guess the waves formed inside are destructively interfering with each other i.e. canclling each other out much more than the waves formed on the outside. Here's a link to more detail about constructive and destructive interference: http://www.phys.uconn.edu/~gibson/Notes/Section5_2/Sec5_2.htm
  11. My point was not to the study itself but cognitive bias in general.
  12. Isn't it interesting that we can find positive benefits for what are generally considered harmful - if only we look - as you have done here? Seeing what we want to see and ignoring the rest is so easy to fall victim to isn't it?
  13. The researchers make associations of mortality risk between stage of life and protein intake i.e. middle-age people should consume low amounts and the old age higher amounts. Really, the research is about tuning your protein intake according to your stage of life and at certain life phases the risk factor for cancer may be equivalent to smoking. Let's not forget, the cancers from smoking are not the same as from excessive protein consumption. Also, the mention of smoking is likely from the person reporting and not the researchers. "The research shows that a low-protein diet in middle age is useful for preventing cancer and overall mortality, through a process that involves regulating IGF-I and possibly insulin levels," said co-author Eileen Crimmins, the AARP Chair in Gerontology at USC. "However, we also propose that at older ages, it may be important to avoid a low-protein diet to allow the maintenance of healthy weight and protection from frailty..." Graphical abstract from the paper: http://www.cell.com/cell-metabolism/retrieve/pii/S155041311400062X Note the title of the paper: Low Protein Intake Is Associated with a Major Reduction in IGF-1, Cancer, and Overall Mortality in the 65 and Younger but Not Older Population
  14. Yes I can see that was likely the intent of the authors and compilers.
  15. I saw the story as Man's transition from animal to autonomous thinker with self-awareness and self-determination ...God let go of controlling Man's destiny from therein basically because he had acquired freewill. I'm not saying I'm right but this has always been my interpretation in the absence of 'correct' teaching.
  16. My thoughts as well ..the question was reasonably answered in the negative long ago. To argue otherwise would be a teleological one and that is the domain of religion.
  17. Last I heard it could be got rid of in 40% of cases some years ago ...that was with a Ribavarin-Interferon coombination. Treatments seems to be more effective now. This was published today: An estimated 3.2 million people have HCV, but the vast majority are unaware they have it, the AJMC noted. HCV gained steam in the early 1980s, before blood products were routinely screened for its presence. Screening people for HCV would allow candidates for treatment to rid themselves of the disease early, before complications become difficult and expensive to treat. Targeting the baby-boomer generation before most of them retire would allow those found to be carrying the virus to obtain treatment under commercial insurers, rather than Medicare. The cost of treatment to cure HCV, which may be possible in 90 to 94% of cases with new therapies, must be weighed against the cost of caring for what was once an expensive, long-term chronic condition, noted one of the panelists. http://blog.pharmexec.com/2014/02/28/changing-the-hepatitis-c-treatment-landscape/
  18. Try this as a last chance: http://en.community.dell.com/support-forums/laptop/f/3518/t/19494727.aspx
  19. Battery's had it by the sound of it or at least it's regulation mechanism is faulty if not the cells themselves.
  20. What does it do with no battery in and plugged in when you power on?
  21. Sorry, I missed the note about the maximum temperature in open air is only 500c. It's inert properties are good though aren't they?
