  1. http://www.foilcenter.com/knowledge/indepth.html Here is a site that tells all you ever wanted to know but were afraid to ask about aluminum. Check out the link to the chemical composition. Virtually all the aluminums used in industry are alloys. In the machine shop we use the 6061 alloy most frequently.
  2. 1. How can that be true? Time is infinite, but you are not. 2. Not true either - you can't even get in "study mode" in ten minutes. 3. I think that is true. The trick for me to remember something is to write it. I can read it 50 times and not remember it, but if I write it in my own words, I will. I have to want to remember it to make the effort to write it down. 4. False - if you forget them in one to two days, you didn't learn them to begin with.
  3. You might be a redneck: If taking your wife on a cruise means circling the Dairy Queen. You think the last words to the star spangled banner are "gentlemen start your engines." You believe dual air bags refer to your first wife and mother-in-law. You've been married three times and still have the same in laws. You lit a match in the bathroom and blew your house right off its wheels. Your sister is the third generation of women in your family to conceive a baby as a result of an alien abduction. You think Subdivision is part of a math problem. You can get dog hair out of your belly button. You think loading the dishwasher means getting your wife drunk. You take a load to the dump and bring back more then you take. You let your twelve year old daughter smoke at the table in front of her kids. You think that a woman who is "out of your league" bowls on a different night. The Halloween pumpkin on your front porch has more teeth then your wife. You think taking a bubble bath starts with eating beans for dinner.........
  4. A circus train derailed in a very backwoods area and some of the animals escaped. Ma looked out the window and screamed at Pa - "You gotta come here and look, there is an enormous gray beast in the garden." Pa, who was settled in and wanted to sit a spell, replied, "So - what's it doing?" Ma said, "It's pullin' up my cabbages with its tail." Pa asked, "Well, what's it doing with them?" Ma: "You wouldn't believe me if I told you!"
  5. Well, I once read that breathing into a paper bag will cure hiccups because the CO2 builds up. Suppose you used a paper bag with a few small holes, so some oxygen could come in but the CO2 would be higher.
  6. http://www.drsfostersmith.com/pic/article.cfm?dept_id=0&siteid=5&acatid=301&aid=592 I read an article in a science magazine that said the African Gray Parrot was the most intelligent bird.

  8. In about 30 seconds you're going to have globs of aluminum melted in the wheel - they won't be powder. What comes off the wheel will fly all over the room and be contaminated by the dust that's on the floor. What comes off the wheel will be sparks - in other words, it will be burnt. Will it still perform as you want it to? What in the heck is wrong with spending $7 on a can of already powdered aluminum? Are you supposed to be making it for a science project? PS - Trust me, I own a machine shop and have worked in the trade for 30 years.
  9. The wife came home just in time to find her husband in bed with another woman. With superhuman strengthy borne of fury, she dragged him down the stairs, out the back door and into the tool shed in the back yard. She put his penis in a vice, then secured it tightly and removed the handle. Next, she picked up a hacksaw. The husband was terrified and screamed, "Stop! Stop! You're not goin to cut if off, are you?" The wife, with a gleam of revenge in her eye, put the saw in her husband's hand and said, "Nope, I'm going to set the shed on fire."
  10. Do not put aluminum on a bench grinder, it will melt and ruin the stone. What need is emery cloth http://dictionary.reference.com/search?q=emery%20cloth and a small block of aluminum. If there are any machine shops in your area, go see them and ask them for a few drops. Those are the leftover chunks of bars. The only way you can get powder is to sand it, and it is going to be messy. As you sand, the aluminum powder will stick in the cloth. It will probably take you a day to make a teaspoon full of it, so I hope you are patient. You can make it faster if you have access to a belt sander. (http://doityourself.com/store/6236152.htm) You can probably rent one at a rental center. This one even has a dust collection bag. However - you have to be very careful, these machines will eat your fingers. You will want to hold the aluminum against the sander with a pair of insulated pliers, because the metal will get very hot. Do not wear gloves - the machine will catch the material and pull your fingers into the machine. The cheapest and least labor intensive way out is to buy a can of it at a marine supply store. You can buy it online at $8 a can from Defender: http://www.defender.com/cgi-bin/Web_store/web_store.cgi?catalog=750413&frames=yes&store=yes
  11. Do you Brits have Walmart? If you don't, you won't get this. BENTONVILLE, ARK (AP) -- Some Wal-Mart customers soon will be able to sample a new discount item: Wal-Mart's own brand of wine. The world's largest retail chain is teaming up with E&J Gallo Winery of Modesto, California, to produce the spirits at an affordable price, in the $2-5 range. While wine connoisseurs may not be inclined to throw a bottle of Wal-Mart brand wine into their shopping carts, there is a market for cheap wine, said Kathy Micken, professor of marketing at Roger Williams University in Bristol, R.I. She said, "The right name is important." So, here we go: The top 12 suggested names for Wal-Mart Wine: 12. Chateau Traileur Parc 11. White Trashfindel 10. Big Red Gulp 9. Grape Expectations 8. Domaine Wal-Mart "Merde du Pays" 7. NASCARbernet 6. Chef Boyardeaux 5. Peanut Noir 4. Chateau des Moines 3. I Can't Believe It's Not Vinegar! 2. World Championship Riesling And the number 1 name for Wal-Mart Wine .... 1. Nasti Spumante The beauty of Wal-Mart wine is that it can be served with white meat (Possum) and red meat (squirrel).
  12. http://www.cryptosafari.com/bcscc/cadborosaurus.htm I think the name of the mysterious beast has been spelled incorrectly. Googling the correct spelling turns up all kinds of pages about it: http://www.google.com/search?hl=en&lr=&ie=UTF-8&q=Cadborosaurus+&btnG=Search Almost all of them are ".com", I didn't seen one ".edu" in the bunch.
  13. Who thought that? Not me. I do know that a number of US Catholics feel that way. People are territorial, just as many animals are. That will fight to the death over land they think of as "theirs", and that is the basis for many of these fights. For example, I wonder what would have happened if the Jews hadn't been given a portion of Palestine after the war? The Jews still wouldn't have a homeland, but the Middle East would be a less contentious place.
  14. I understand "crikey", (but don't know if there is a literal meaning to it) & "nosebag" (we call them "feedbags"), does "fair dinkum" mean "quite good"? I realize "bob" in a unit of money, have also heard "quid" are they both slang for pound? I sure don't know what "dogs eye" and "dead 'orse" mean.
  15. How long does it take to slow down and stop? One must have a very accurate knowledge of the precise distance one has to travel.
  16. The title of your thread was, "What goes through the mind of a terrorist?", but then you muddy the waters by including bank robbers. Obviously, a bank robber believes, stupidly maybe, that he will get away with it. Many terrorists accept death as a means to an end. Those who hijacked the planes on 9/11 knew they were going to die if their mission was to be a success. What goes through their minds? I'd say they've probably been brainwashed from a young age. Think about the Taliban regime and the way they treated their women. I believe there was more to the wearing of the burkas and the enforcement of silence than the subjigation of women. The taliban removed young boys from their homes at an early age and put them in those schools (that I can't remember the name of right now). In doing so, they removed all maternal and female contact from these young boys. Not only did they not have a mom to hug them and care for them, they didn't even see the smile on a woman's face, or hear her voice. Their entire existance was a study in cruelty at the hands of their "teachers". Under such conditions, I would think one would not value one's own live much, especially if one was taught about the reward they would obtain in Paradise for murdering infidels.
  17. Why is it that IE keeps crashing after I have typed, copied and pasted - aarrgh! Link from World Book: http://www2.worldbook.com/wc/popup?path=features/dinosaurs&page=html/trex.htm&direct=yes Snippet:
  18. I got so carried away with the impact bit, I forgot to throw in what I had read about gamma ray bursts. http://solarsystem.nasa.gov/scitech/display.cfm?ST_ID=246 http://arxiv.org/abs/astro-ph/0309415 http://www.planetsave.com/ViewStory.asp?ID=4647 A google search page: http://www.google.com/search?hl=en&ie=UTF-8&q=gamma+ray+bursts+mass+extinction
  19. Visual, auditory, and kinesthetic or tactile. We learn by seeing, hearing, and touching. Most people are primarily visual learners, with auditory secondary and tactile tertiary. Some people are primarily auditory, we remember best what we hear. I think nursery rhymes are a way of teaching children auditory learning. It is easiest to remember something that rhymes, but it trains us to use our ears to listen, rather than just to hear. IMHO, what needs to be started earlier is teaching children to think. Currently, for the most part, we throw facts at them and expect them to remember them by rote. Very small children can be taught to think if you take the time. I know I am full of anecdotes, and I apologise, but here is an example. My grandson was about four and I was minding him on our boat while my husband and son-in-law worked on the engines. SIL hadn't brought any toys, so I was trying to find something to pique his interest. He saw a nautical chart and asked me what it was - I told him it was sort of like a picture of the area as you would see it if you looked down from a plane. He asked me what the yellow part was, and I told him it was the land. He asked me what the blue part was, and I told him it was the water. He asked me what the black lines were and I told him they were roads. Then I showed him a spot where a black line went from yellow, across some blue, and back to yellow. I asked him what it was. He looked at it for several minutes, and thought really hard, then looked up at me with his eyes sparkling and said, "It's a bridge, Grandma!" The classic "Aha" moment. Nursery rhymes are simply ways to teach children to remember what they hear and repeat it. They are sometimes called "nonsense rhymes". The Dr. Suess books are a classic example. How many of you learned your "abc's" from "the alphabet song" How many of you learned your numbers from "The ant's go marching".
  20. It is becoming increasingly more evident that impact events have caused most, in not all of the previous mass extinctions on earth. I don't believe nuclear war is anywhere near as probable as it once was. I am a child of the 60's. I remember atomic bomb shelters, and "duck and cover" drills, where we were told to crouch beneath our desks. (Later, we became aware of just how futile that was and joked about "putting our heads beneath our knees and kissing our butts goodbye") I do not believe that any of the larger nations would start a nuclear war. All that are capable of mass annhilation know that the favor would be returned before the missiles even reach their targets. There are a couple of rogue nations who might try it, if they become capable of intercontinental delivery. They would have to accept the fact that by starting a war they were committing suicide. I think the retaliation against them would be measured. So - if you're talking mass extinction from an impact event, you wouldn't be dealing with radiation, but you would be dealing with an "impact winter". A lot would depend on how much warning we had, but large objects go by relatively closely on a regular basis, and we don't know how close they came til after they've gone. Here are my thoughts on a "post-impact world" 1. In all the previous extinctions up til the next one, the creatures that were alive at the time had no means of altering their environment. We do and more importantly, we have. 2. The biggest factor would be at what angle the impactor arrived and where it hit. For example, evidence suggests that the Chixulub Impactor hit on an angle that set fire to most of North America. I have read logs from cores in this area - the K/T impact strata is referred to as a "barren zone", and it often mentions large quantities of carbonized (not as in "Carboniferous" or from that period) material, so that supports the theory put forth by this article. If the impactor was closer to a 90 degree angle, and dropped in the ocean (most likely, since 3/4 of the earth is ocean), certainly all marine life within hundreds, if not thousands of miles, would immediately perish. The resulting tsunami would wipe out all life on the coast of both bordering continents. 3. I don't think humans would go extinct as a direct result of the impact. We have a big advantage over all the creatures that existed before us - we can think and have the manual dexterity to apply our knowledge. They might eventually go extinct if the impact decimated the population to the extent there wasn't a viable number left to survive plagues of "new" diseases. 4. Certainly, the organisms occupying some niches would go extinct and leave them vacant. There would be a lateral spreading to occupy the vacant niches. One other survivor would almost certainly be the 17 year locust: http://insects.ummz.lsa.umich.edu/fauna/michigan_cicadas/Periodical/Index.html By the time the larva that were underground were ready to metamorphize, the dust would have settled - literally.
  21. I read (and remember, LOL) that the sex hormones are at their highest when humans are about 17 years old. In this society, that's deemed too young. People haven't completed their formal education and few of them have the financial assets necessary to marry and start a family. However - it wasn't so long ago that most people didn't live much beyond 35, and since humans require parental care for a much longer period of time, it makes sense that the children of the youngest parents were most likely to survive long enough to reproduce. I have also read that the onset of puberty, especially in girls, is happening at younger and younger ages - sometimes as young as 8. I've read that it may be associated with the hormones that are fed to livestock to bring them to maturity earlier. So what's the answer to that? Bring back the chastity belt or start kids in school at age 2 so they complete their education in sync with their hormones? Or - cringe - perhaps research methods to reset the puberty clock to a later age.
  22. You can build lighter cars, but you have to remember, cars don't always run into one another. Cars run into trucks and buses (& vice versa), as well as utility poles and concrete walls. They are also subject to rolling over. They have to be strong enough to afford reasonable protection to their occupants in these situations.
  23. Will mull over your explanation in detail in the AM. I'm bailing out for the night. The tail end of Ivan just started blowing through and the wind is really picking up - will shut down the puter 'fore it gets shut down. L8R.
  24. What is it that you are freezing and boiling? Fresh water? I am baking a cake in the oven at 350 F, what is the temp in Fh?
