On Topic - Transparent Aluminum
Not quite up to the level of Start Trek stuff, but.... Professor Wark added: ‘What is particularly remarkable about our experiment is that we have turned ordinary aluminum into this exotic new material in a single step by using this very powerful laser. For a brief period the sample looks and behaves in every way like a new form of matter. In certain respects, the way it reacts is as though we had changed every aluminum atom into silicon: it’s almost as surprising as finding that you can turn lead into gold with light!’ http://www.sciencedaily.com/releases...0727130814.htm |

I guess it's "interesting" in a way, but since there isn't even the
suggestion of a possibility of it remaining transparent without constant application of large amounts of energy, I'm not sure there's any use for this particular transformation (unless it has other properties that make it useful in a physics lab). It does remind me of the Star Trek movie they reference...where the crew goes to great lengths, including changing the course of history on earth, to obtain some "transparent aluminum"... Of course no one ever explains why "normal" aluminum wouldn't have made a perfectly sufficient whale tank other than the fact that it wouldn't have looked as cool... |

Transparent aluminum is just the start. The physical properties of the matter we are creating are relevant to the conditions inside large planets, and we also hope that by studying it we can gain a greater understanding of what is going on during the creation of 'miniature stars' created by high-power laser implosions, which may one day allow the power of nuclear fusion to be harnessed here on Earth As for the Star Trek movie, regular aluminum wouldn't allow us to see the whales! What fun would that be??? |

Galvanized and gilded metal atoms??
They turned out to be steelworkers, running their steel mill in the nanoworld -
the chemists around Prof. Dr. Roland A. Fischer (faculty of chemistry of RUB). In the neverland between molecule and metal they discovered a new family of compounds. The prototype of these new “nano alloys” is a compound containing one central molybdenum atom binding twelve zinc atoms. The icosahedral metal chunk is wrapped into hydrocarbons and therefore surprisingly stable. Its construction is transferable to both other metal centers and other structures. Also the zinc atoms can be exchanged to other metal atoms, even to gold. http://www.sciencedaily.com/releases...1112075039.htm |

You know, the old "weight in pounds per thousand equals the price each in pence[Detritus - hence the d]" back when 10 pence was a fair wage. Ah reckon labor has gone up a mite since then. Cross cultural comparative cost is always the tricky part, particularly when trying to do it in history. "Equivalent purchasing power" is hard to figure when something isn't in one era. E.G. computers, canned goods, stereos. Even then you have the problem of Gizmo X was 100 credits in year Y, five years later were 105 credits, but accomplished twice as much. (Computers, mobile phones, telegrams, automobiles, etc,etc, ad nausm.) From a lecture I heard on woodworking in the Middle Ages, pay rates then were comparable to those today, but that iron cost like silver and steel like gold. Hence it was more cost effective to hire a master carpenter to cut 8 mortise and tenons an hour for construction than to use nails. In those days, it was the material cost which killed a budget. Today, we have steel so "cheap" we make nails from it, and those so plentiful we don't care. Now it is our labor costs which kill the budget. In "the old days", a 2x4 would be two inches by four inches, and the side which would be seen would be smoothed at the worksite. Now, all our 2x4s are not two inches by four inches, but they come from the sawmill smoothed on all four sides - "just more efficient to do it that way." Sorry, I fall in to lecture mode too easily. I've done woodworking with hand tools - no power tools at all. As Ditto here, and I'm a recovering Neanderthal. Well, we had Fire in our village. Neat stuff, long as you don't get any on you. - pyotr filipivich We will drink no whiskey before its nine. It's eight fifty eight. Close enough! |

Let the Record show that "Ed Huntress" on or
about Sat, 1 Aug 2009 19:21:17 -0400 did write/type or cause to appear in rec.crafts.metalworking the following: a hobby, it is fine. But you realize why power tools were invented. And that extends to machine made nails vs the traditional hand hammered ones. Ayup...and then some. Nails were made all winter by the blacksmith when he had spare time. They were expensive then. When settlers picked up stakes and moved, they would torch the house a lot of times and sift out the nails. When people do that today, it gets them 3 to 5 in the state pen. d8-) Call the fire department, arraign for a "training burn". Fun for the whole family and you can even bring marshmallows! If you bring marshmallows, then it is a "cooking fire" - and exempt from the burn ban, too! B-) tschus pyotr - pyotr filipivich We will drink no whiskey before its nine. It's eight fifty eight.
