  1. Houshase: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058260/ Maybe .Glasses problems tend to be heredity but environment is a factor.Age of onset can be hereditary as well. Myopic children tend to be more myopic than their parents. Why? It is normal to lose near focusing ability over 40 or so.This is for sure hereditary.This means you cant adjust your focus from far to near work like reading. This is presbyopia relieved by reading glasses, not farsightedness. Sufficiently hyperopic { farsighted} people need glasses even to see far though their near vision is even worse. without glasses. Hyperopia or far sightedness can occur at any age as can myopia or astigmatism.Astigmatism requires glasses or contacts with more power across one meridian, called cylinder lenses. Think of a football or spoon curved differently along different meridians. I theorize evolution is a factor in what seems a fairly recent epidemic of myopia. Near work is a factor likely but also a person with myopia long ago had less chance of surviving to pass on genes...Glasses even the field somewhat and the gene gets passed along.
  2. Stringjunky: "The idea is well-intentioned but, as you realise, the consequences would probably be largely negative" If you are referring to the penicillin bullets and spikes instead of airbags you are correct about my realizing the largely negative consequences. Otherwise you have no idea what I realize. Thiamine supplements in alcohol should be beneficial to those with thiamine deficiencies often associated with alcohol abuse. That would only be one of millions of excuses to abuse alcohol. Actually any excuse will do. Trust me. I wouldn't forgo thiamine supplements in alcohol that could save a few lives because it would give some people one more excuse to abuse alcohol.I doubt many would need the excuse.Alcohol shouldn't be sold because it kills so many abusers?
  3. John Cuthbar: Colorful analogy.Spikes would kill more than they save.To be on the safe side don't suggest it to your Senator Airbags do kill some.So do seat belts but they save more than they kill.Unlike penicillin laced bullets likely. Still none of the government's business IMO.I was only suggesting thiamine supplements in relation to alcohol abuse and thiamine deficiency.You raised a good point though.. Abusers by their nature though tend to disregard the hazards and generally wouldn't drink larger quantities because the alcohol has thiamine.I have no stats or references of course.Generally habitual abusers drink as much as they can. They cant get any drunker because of the added thiamine.That would sell..I drink gallons of skim milk, not because it is vitamin supplemented. Never even think of it. Better than the spike analogy?As a former beer abuser all I cared about was cost, calories and bang for the buck.I drank as much as my body could stand.
  4. Sorcerer: Wow, they sure smm sure of themselves. "It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once," Das said. OK, except for a few little details like maximum entropy and 2nd law of thermodynamics. Aren't there a few others? Infinite black holes? Infinite Star Wars sequels?
  5. Jagella: " John Lennox, for example, has said that atheism is wishful thinking in that it is the hope that atheists will never have to meet God." Thanks, I never thought of that. Maybe some atheists.Reminds me of my brother before he died. Claimed to be atheist but followed a sorta religious lifestyle just in case. You know, do unto others, no blasphemy, respect your elders etc. Don't know how or if that might have worked out. Seems atheism has become a sort of religion where the atheists have faith that there is no God.Lack of proof is considered proof I guess. Ever since the first religions, followers have been claiming to be persecuted and have been.. Religion has an important place in society but scientific methods need not apply.Scientists don't try to aggravate or persecute the religious but their opinions are offensive to religious people whose religion generally requires defending their belief.Say what you believe and let the chips fall as they may.Scientists have been known to be opinionated. Never argue religion with a naked man. Happened at the YMCA locker room.
  6. Strange: i see what you mean so far.Thanx
  7. Lanr12: Tech for self guided curving bullets is here and now. I assume some type of targeting is involved. Didnt see the movie.Some bullets can bend in flight with smart muscles.About $10,000/ bullet, not at discount stores yet. Types of smart bullets[edit] Wikipedia In 2008 the EXACTO program began under DARPA to develop a "fire and forget" smart sniper system including a guided smart bullet and improved scope. The exact technologies of this smart bullet have not been released. EXACTO was test fired in 2014 and results showing the bullet alter course to correct its path to its target were released. In 2012 Sandia National Laboratories announced a self-guided bullet prototype that could track a target illuminated with a laser designator. The bullet is capable of updating its position 30 times a second and hitting targets over a mile away.[2]
  8. Strange: '"A homogeneous distribution of mass will not form a black hole." I never knew that. Some clarification or links please. Also this need some have to determine the mass of the known universe while others wonder if the whole universe is infinite seems strange. http: //curious.astro.cornell.edu/about-us/101-the-universe/cosmology-and-the-big-bang/general-questions/579-what-is-the-mass-of-the-universe-intermediate
  9. Alexander1304:The Universe is all of time and space and its contents. Wikipedia. I have read this or similar since I could read.How can one have more than one of everything? Does this theory and others that propose more than one universe require a new definition of universe or is this a contextual thing were broad meanings are taken for the word universe and the physicist uses different definitions based on context.This is done in physics and other fields.Photons are said to have no mass but have momentum.You know what momentum is..
  10. Henry: I too have little regard for religion per se. Not exactly against it. Some get a lot of good out of it, gets them through the night.. Others? An excuse for killing or as a means of making money or acquiring power.Gives religion a bad name,justifiably. Can Science explain everything in the universe without a God? It certainly cant explain everything. Not at this time.Possibly hidden distance variables in QM for example.Have those been discovered or confirmed or denied or explained.Not by Bell last I heard.He doesn't rule them out.Woopie! Must be other things science cant explain yet.. Can you think of anything? Could science ever explain it all?,Seems solutions present more problems that need answers. I'll wait and see. Wont hold my breath. Would explaining everything in the universe by science prove no God? Hardly.Maybe God uses what we might call science to do or get things done. Want proof?.Sorry,none I know of.

    Pellagra

    Becki: I was not aware that the gastrointestinal issues are the first to present in pellagra. It affects the whole body with the three D's. dementia, diarrhea and dermatitis. Dementia can be slow to detect, skin irritation may present gradually but diarrhea tends to be pretty quick,and maybe the first noticed.The gastrointestinal tract can be less tolerant of discomfort than the skin in some ways.An itch on your hand may be more tolerable than one in your colon.
  12. Strange: "It is still not a black and white issue. It might be important to save some species and not others, for example." I would agree with this.We are saving some species and not others.On the one hand we protect apparently doomed species to the detriment of jobs and industries {some owl} as our activities eradicate others {plastic bags and sea turtles} .We are having an effect.Which we save and which we prolong is important but who decides which.I think maybe we should protect certain species and allow others to pass on. Who decides which and by what means? We may be the first sentient species, does this carry some responsibility or not. The ultimate responsibility seems to our own species.To other species,sure, but not to our detriment.We are fooling with mother nature and have little idea what we are doing.
  13. Shokel: All vitamins may be depleted to some degree but the proximate and main problem is the thiamine deficiency most common in alcoholics. All nutrients are addressed with emphasis on massive amounts of thiamine for this reason.The thiamin deficiency or kidney or liver or other failure can kill long before the other vitamins are much of a factor. Also called Korsakoff's, alcohol is not always involved. it is a form of cerebral berri berri and causes massive brain and memory loss. Permanent. Usually fatal when finally diagnosed.If not fatal the person must be cared for for life. See "The Man Who Confused His Wife For a Hat" My feeling is that it could be largely avoided if alcoholic beverages were thiamine supplimented.
  14. Strange is correct of course.Do you mean,why the universe has to be a space time continuum in the first place? Who says it had to be? It might just happen to be the way it is. Totally different methods,laws or variables might have been used or always been.We cant comprehend a universe like that.Philosophical realm I suppose? We are creatures of 4 space time dimensions and cant likely visualize otherwise.
  15. Googlekoph: If this happened years ago you may not find a cure but to know the cause would be nice. Some therapies might help. .https://en.wikipedia.org/wiki/Music-related_memory#Neurological_bases
