One could,of course, perform the same experiment using a block of steel instead of concrete--steel is even denser than concrete, after all. And yet steel and other metal alloys are the preferred materials for making large vessels to float both on water and in air. Don't get me wrong, wood is a magnificent material, but it does have its limits. (Tuesday Mar 10 | post #245868)

Actually, the most recent Harris poll (December 2013) puts that figure at 74%, meaning that 26% have some level of doubt, and every study I've seen indicates that the percentage of admitted nonbelievers is still growing. (Jan 27, 2015 | post #3)
That's true, but links are still useful for providing references to support the ideas in a post. They are not always used as substitutes for original thoughts or good writing. (Jan 13, 2015 | post #24838)
The assumption that some cannot stand up for themselves can be self-fulfilling. Self-appointed "heroes" often do more harm than good. (Jan 13, 2015 | post #14085)
How would you implement such a prohibition? Would you,for instance, be allowed to call someone a "frikken idiot"? Who would enforce such laws, and what kinds of consequences would be imposed? Would you be inclined to radically alter the Constitution? Might not an oppressive society result that would do more harm that it prevented? (Jan 13, 2015 | post #14084)
For me, the best definition of a Christian is someone who believes that Christ was the promised Messiah and endeavors to understand and follow His teachings. That covers a pretty wide range of belief and practice. Many Christians insist that only those with the same understanding are "real" Christians, but to me, that's just simple narcissistic prejudice. It's also why, as a nonbeliever, I cannot pass judgement on Christians as a group. Most are genuinely good people who try to help others and make our world a little better in whatever ways they can. I am less generous towards those who use religions as an excuse to express fear, hatred, and malice towards those whose ways differ from their own. Much of the harm that they do is unforgivable.

A quick update: after a couple of visits,during which I informed the JWs that they were in violation of the apartment complex's policy, I asked the office staff to call the local Kingdom Hall and remind them that their folks were welcome only as invited guests and only to the units to which they've been invited. Then I called our security officer whenever JWs knocked on my door. The visits stopped, and it's been over a year since I've been disturbed. I'm pretty sure, though, that only the threat of arrest and prosecution accomplished that restraint. (Dec 28, 2014 | post #139)
That's what he does--makes his unsupported claim, supports it with more unsupported claims, ignores all refutations, keeps his head head after the inevitable ignominious defeat, then makes the claim as if none of the aforementioned had ever taken place. Wash, rinse, repeat. pretend he's "winning. " Why anyone is willing to continue "playing " is beyond my comprehension. (Dec 27, 2014 | post #380)
Perhaps some scientists do say that, but the ones who were cited in the Independent article to which you provided a link do not. What they do claim is that by using short laser bursts of a specific range of frequencies, they were able to duplicate the current state of the shroud in a very short time. Interpreting those results to mean that the shroud was so produced,though, assumes, that its image was also produced quickly and has remained unchanged since that time. But the historical data presented in another link clearly shows that the shroud's image was originally more colorful and better defined and has faded greatly over the centuries, being displayed periodically in outdoor settings in full sunlight for the first few centuries of its provenance. Without another eight hundred years to play with, it would be difficult to duplicate that sequence and just as difficult to say for sure that a painting could not have degraded into the shroud's current state. Since the authors of the paper cited (Deep Ultraviolet Radiation Simulates the Turin Shroud Image, Paolo Di Lazzaro et al) do not say that 'Shroud of Turin is the burial cloth of Jesus: proving God exists; Jesus is God; and Christianity is the one true faith,' perhaps you would be so good as to provide another citation by scientists who do make that claim. http://www.frascat i.enea.it/fis/lac/ excimer/sindone/Di %20Lazzaro%20-%20d eep%20ultraviolet% 20radiation%20-%20 JIST.pdf (Dec 24, 2014 | post #2770)
For anyone who is curious, here is a link to the paper that the newspaper article referenced. There's no indication that Michael Day, the Independent's Italy correspondent,has any training in science, and it looks like he may have been a little fuzzy on some details. The paper itself never uses the word "supernatural ," nor does it claim that the method that they used to produce similar (not identical) physical and chemical results as had been reported by the Shroud of Turin Research Project in 1978 is the only way that the shroud's image could have come about. http://www.frascat i.enea.it/fis/lac/ excimer/sindone/Di %20Lazzaro%20-%20d eep%20ultraviolet% 20radiation%20-%20 JIST.pdf I don't trust newspaper reporters to get scientific stories right--nor should anyone trust me for the same reason--except for some science editors, none of us have the training to keep from inserting invalid interpretations into the reporting. Best go to the original source, Perhaps Christine can tell us whether the Journal of Imaging Science and Technology is peer reviewed. (Dec 23, 2014 | post #2675)
That is odd. Two of my daughters are very obscure PhDs, one a biologist,the other a mathematician. If I google them, every paper that they've published shows up in the results, including the translations into other languages. That should be even more true of any scientist who is more prominent. For him to appear nowhere else suggests to me that he has never published a peer reviewed paper, which in turn suggests that he never earned a PhD in any of the hard sciences. Perhaps the name was simply made up to sound impressive and no such person actually exists. (Dec 22, 2014 | post #2653)
I'm not actually interested in the shroud--old subject, already kicked to the curb, resulting in the abject defeat of a poster named Paul a couple of years back. What intrigued me was the claim that 3D data could be encoded in a 2D grayscale image. While that's obvoisly not true, the challenge of using GIS encoding to derive 3D data from a grayscale image was fun to think about,so I thought I'd share,and Uncle Sam's ludicrous responses to my post also provided some wry amusement. (Dec 22, 2014 | post #2652)
The only way that I can think of for a 2D image to contain 3D information is for each pixel to have height/depth information encoded or implied--GIS technology does this in order to display landscape contours that are accurate from each viewing angle. In order to generate those values from a grayscale image, height/depth values would have to be assigned in a continuum across the range of shades from light to dark after defining a bitmap grid across the image. The shape of the bitmap would then have to be adjusted to allow for the distortions that the three dimensional shape would infer. This could be done with any grayscale image--black/white photos, for instance, or artistic renderings with pencils, pen and ink, or charcoal. But there's no reason to think that the results would necessarily correspond to the realities from which any of these were made. Nor are any of these images inherently uncoded with 3D information. And this is just my guess based on the way GIS images that I studied were encoded--there could be other ways. But within this method, the 3D values are inferred from, not encoded within the grayscale images. (Dec 22, 2014 | post #2589)
