[Joshua W. Burton] ---------------------------------------------------------------------- From: Jonathan Katz <frisch1@...> Date: Mon, 17 Oct 1994 00:21:44 EDT Subject: Creation and Science This may be a (relatively) unimportant point, but I feel that it must be made: Anyone attempting to "answer" the "contradictions" between science and creation should at least research both sides before suggesting an answer. I.e., one should not just spout off an answer because it sounds good, when there is no basis in fact for it. Two recent statements have caused me to write this: "Many other problems can be explained by the mabool...a pressure of about 5000 meters of water covering the earth's surface could have an affecton [the rates of 14-C radioactivity]." This is a very nice statement, but absolutely unsupported by any current scientific theory, or any scientific evidence. Scientists have never found a method to appreciably change the radioactivity rates for atoms, and they have studies the effect of pressure, temperature, among other variables. 2) regarding Prof Schroeder's theory which uses general relativity to "explain" the difference between the scientific age of the universe and the religious age - have any of the people advancing this claim actually read Dr. Schroeder's book? I have, and although I don't claim to be anywhere near an expert in relativity theory, I can say that his arguments didn't convince me. I do not mean to imply that he is wrong, merely that since I could not replicate or follow his results, I don't go around claiming that he has "solved" the problem. Jonathan Katz <frisch1@...> 410 Memorial Drive, Room 241C Cambridge, MA 02139 ---------------------------------------------------------------------- From: Yechezkel Schatz <lpschatz@...> Date: Subject: Science and Creation Date: 18 Oct 1994 11:43:44 +0200 After I read Joshua Burton's posting I realized that, not being a physicist, I may not have been very accurate in the way I presented my father's theory on the mabul and C-14 measurements. So I went home and checked the topic in his book, and went to speak to him about it, and sure enough I did not do justice to his theory on the topic. However, before I admit that what I wrote is scientifically wrong and stress the main issues in my father's hypothesis, I would like to ask Joshua 2 questions: 1) you write: >We routinely use carbon in diamond-anvil high-pressure chambers, at pressures a thousand times higher yet, and no one has observed any change in the rate of carbon-14 decay. *Have any similar expriments been done under high pressure with water over a lengthy period of time, say half a year (as long as the mabul)? 2) you write: >Heavens, we study the details of the carbon-nitrogen-oxygen fusion cycle in massive stars, at pressures ten MILLION times higher than any pathetic little water flood...and if the rate of C-14 decay were changed by a fraction of a percent, the models would fail completely. *What are these models? What if they do fail? (would they, for example force us to conclude that the sun revolves around earth?) And now I must explain what the main issue in my father's thoery actually is: In samples subjected to such high pressure in the presence of water for such an extended period of time, we have the problem of selective leeching. This means that water could seep in to our sample, introduce contaminations to the sample, and selectively dissolve and leech out one of the carbon isotopes. This would cause an alteration in the ratio of C-14 to C-12, and therefore affect the calculation of any date prior to the mabul. This effect has to be experimentally tested (anyone out there interested in a thesis topic?). I would like to stress that C-14 measurements have been found to be reasonably accurate (by validating them with archeological findings, for instance) for dates until as early as the mabul, BUT dates prior to that could be affected by the sampling problem. Note that C-14 measurement take us back to a maximum of about 50,000 years (a factor of 10, when compared with the date of the mabul!) One of the main points here is that as a Jew I believe the bible to be a much more accurate historical record than some of the contemporary scientific calculations, which base themselves on a lot of unproven assumptions. My father's approach is to start out with the basic assumption that we can accept the biblical chronology as accurate, and from there he moves on to prove it, whether by reinterpreting passages in the Tanach, or by taking a closer look at world history. You would be amazed how well it pays off! In his book he covers all periods of biblical history and comes up with many original, sometimes shocking theories. ---------------------------------------------------------------------- From: <rotha@...> (Arthur Roth) Date: Sun, 16 Oct 1994 13:34:08 -0500 Subject: Shabbat and Wheelchairs A number of people asked me to find out more about the Rosh Yeshiva (RY) who was wheeled by his talmidim in the streets on Shabbat without an eruv. Over the weekend, I spoke to one of the talmidim on several different occasions to make sure all the details were clear to me. What I found out was, to me, rather unsatisfying, but I'll pass it on as promised for what it's worth. 1. The RY paskened only for himself only and not for anyone else. He had his talmidim wheel him ONLY BACK AND FORTH TO SHUL AND NOWHERE ELSE. He listed a few possible heterim that COULD be relied upon, but on a personal level (not as a psak) he rejected all but one. The only one he actually accepted for himself (which to me seems awfully farfetched) was that in his case it was actually a matter of pikuach nefesh (danger to life). He felt that never going to shul on Shabbat would over time create enough emotional stress and despair that it would actually kill him. He emphasized that this reasoning was particular to his own upbringing, hashkafa, and emotional state, and that it would not apply to too many other people. 2. The RY apparently DID give a blanket heter for wheelchair-bound people to transport themselves, if able, by gripping and rotating the wheels or by other devices that may be built into the wheelchair which operate mechanically rather than electrically. The basis for this heter is what I stated in my last post, namely that THE WHEELCHAIR IS REGARDED AS PART OF THE PERSON HIMSELF, AND THIS CONCEPT IS PRETTY WIDELY ACCEPTED, THOUGH THERE ARE SOME WHO DISAGREE. Presumably (but the talmid I spoke to said he had never heard this mentioned explicitly), this would mean that both the person's house and his destination would have to be wheelchair accesible via ramps, doors on the street level, or some other means, because nobody else could carry the person into or out of either location. Alternatively, if the person could use something such as a cane or crutches to manage just the distance from the inside of the house to the closest wheelchair accessible location outside the house, anyone would be able to lift him into his wheelchair once outside, as this would entail less than the minimum distance which violates the prohibition of carrying. 3. The RY was apparently able to transport himself in his wheelchair, but his progress in this manner would have been so slow as to render it impractical. It would have taken him hours each way to/from shul. This was his basis for a "heter" that he claimed had a halachic basis for those who wished to rely upon it, BUT WHICH HE PERSONALLY REJECTED. To explain this "heter", we first need some background from fairly recent history. It was a widespread practice (in fact, almost universal, but there were some exceptions) in Orthodox communities to carry children in the streets on Shabbat 30-40 years ago. In most cases, no distinctions were drawn regarding the age of the child or the distance he was carried. Despite its prevalence, this practice was in retrospect CLEARLY incorrect, and it was based on a misinterpretation of a certain text that states, roughly, that a person is regarded to be providing his own support. According to the RY, there are two opinions vis a vis the CORRECT reading of this text: (a) Its meaning has no relevance to carrying on Shabbat and pertains to some completely unrelated issue. (b) It means that one may carry a person (and regard the person as providing his own support), BUT ONLY FOR WHATEVER DISTANCE THE PERSON WOULD HAVE BEEN CAPABLE OF TRAVELING ON HIS OWN. According to this interpretation, carrying can be used to alter the speed and/or convenience of an act that would have been permissible anyway in another (slower, less convenient) manner, but not to accomplish something that could not have been permissibly done otherwise at all. In particular, even according to this interpretation, an infant could not be carried any distance whatsoever. When the widespread mistake was "discovered", poskim almost universally adopted interpretation "(a)" instead of interpretation "(b)" in their zeal to correct the widespread improper practice. Any attempt to make this fine distinction between carrying of children that is CLEARLY incorrect and carrying of children that MIGHT be ok (depending on which view is taken) would likely have had little practical effect in the face of a common, widespread practice. It has thus become normative halacha not to carry a child ANY DISTANCE AT ALL AT ANY AGE. However, according to the RY, interpretation "(b)" still has some validity, and there is apparently a small minority of poskim that is still willing to allow use of this interpretation in practice. THE RY REFUSED TO ACCEPT THIS FOR HIMSELF, AS THIS IS NOT THE "USUAL" ACCEPTED ORTHODOX PRACTICE TODAY. But since he was willing to grant that there was some possible validity to this view (though he wouldn't accept it for himself), let us examine what it would mean in terms of wheelchairs. Keep in mind that the wheelchair is considered to be part of the person. (a) It would permit anyone to wheel a wheelchair-bound person anywhere at all (not just to/from shul) on Shabbat, BUT ONLY AS FAR AS THE PERSON WOULD HAVE BEEN CAPABLE OF PROPELLING THE WHEELCHAIR ON HIS OWN. (However, it would not matter how long this would have taken. Thus, had our RY accepted this for himself, he would have been able to go other places besides just to/from shul.) It would unfortunately not do any good for a person so incapacitated that he cannot move his own wheelchair any distance at all. (b) There would still be a problem with entry/exit to/from a building. If the wheelchair-bound person could have gotten in/out on his own (either because the building has a ramp or street-level entrance, or because he was capable of using a cane or crutches to get in/out on his own, even with much difficulty), then this view would allow someone else to carry him in/out. If this ever becomes widely accepted, it would then become important to make shuls wheelchair accessible if at all possible. It goes without saying that the person's house should also be wheelchair accesible. (c) It must be emphasized that this view is not one which the RY accepted, only one which he acknowledged had some halachic validity despite its general lack of acceptance in today's Orthodox world. Thus, anyone wanting to practice in accordance with this view would first have to be lucky enough to have a posek willing to permit this. As usual, CYLOR, but it can't hurt to be armed with all this information at the time the sh'aila is asked. Well, this has taken a rather long time, and as I said at the outset, is not really very satisfying. But it will have been well worth it if it ultimately leads to any more freedom for even one person in a wheelchair. Arthur Roth ---------------------------------------------------------------------- From: <burton@...> (Joshua W. Burton) Date: Mon, 17 Oct 94 00:35:11 -0400 Subject: Under pressure? Yechezkel Schatz, looking for an easy way to reconcile B'Reshit with direct observation, makes a startling claim about physics under pressure: > For instance: when testing for C-14 levels, the most credible > of all geological tests,with the least amount of assumptions underlying > it, we are still assuming that the rate for C-14 break-down was always > the same. And yet, a pressure of about 5000 meters of water covering > the earth's surface could have an affect on these rates. This, if true, would be far more astounding than the Mabul itself. Look, in human terms 500 atmospheres of pressure (what you would experience at that depth) is a lot. It would kill you. It would kill you in at least four ways that I can count, just while wearing my physicist hat and my SCUBA diver hat; I'm sure a specialist in hyperbaric medicine could think of a few more. When it was done killing you, it would crush your SCUBA tank, full or empty, like a rusty beer can. Four tons on every square inch is nothing to laugh at. But to an atomic nucleus it's nothing...vacuum...tohu vavohu. Even that big mushy cloud of electrons around the nucleus only yields by about 0.0001% under such an equilibrium pressure---the water at the bottom of the ocean is really not much denser than at the surface, despite the pressure. But the nucleus has a quadrillionth of the atom's volume, and a million times the binding energy: that works out to 1,000,000,000,000,000,000,000 times the stiffness. Thus, the nuclear binding energy should be affected by about one part in 10^26...and not one carbon atom will decay as much as one second sooner or later, out of thousands of years. We routinely use carbon in diamond-anvil high-pressure chambers, at pressures a thousand times higher yet, and no one has observed any change in the rate of carbon-14 decay. Heavens, we study the details of the carbon-nitrogen- oxygen fusion cycle in massive stars, at pressures ten MILLION times higher than any pathetic little water flood...and if the rate of C-14 decay were changed by a fraction of a percent, the models would fail completely. Of course, the Mabul was no ordinary flood. But if we are going to assume that a miracle changed the rate of nuclear decay, why not assume that it happened when Moshe banged on the rock with his staff? That makes at least as much sense as Mr. Schatz's theory. And it doesn't give a veneer of scientific plausibility to the inexplicable...as the flood theory might, if one were too lazy to work out the math.
