#166743 Adirondacks Hot Spot Message #166751
From: Al Balmer The Science/Math Forum · Geology February 8, 1995 8:32 PM

From: Al Balmer The Science/Math Forum · Geology February 8, 1995 8:32 PM
Nathan, The differences in custom for publishing is understandable, I guess. Publishers usually have a number of authors anxious to be published, whereas computer consultants are generally only writing something because the client wants it badly enough to pay for it. It is customary that a client is given an…

Hi, Doug I've made an effort to stay prepared, since our week in the cold after the ice storm, but it's surprising how soon we forget. The first year after, there were an amazing number of electrical generators in people's garages. The second year, there were an amazing number offered…
From: Al Balmer The Science/Math Forum · Geology February 1, 1995 4:44 PM
Doug, I'm not really up on it, but I know there have been quakes within a couple of hendred miles of Rochester, as I recall, on the edge of the Adirondacks near the Canadian border. You're right about the potential for big trouble. In the urban areas, we're fairly well…
From: Al Balmer The Science/Math Forum · Geology January 30, 1995 10:40 PM
Doug, Luckily, the only noticable quake we've had around here in recent years turned out to really be a massive salt mine collapse. It did jiggle the seismographs, though, and fooled some people for a while. Al

Doug, >> Don't be too hard on the "scuzballs Interesting point. Here in NY, it's illegal to raise prices in the wake of a disaster, unless you can prove that it was a "natural" increase you're just passing on the the buyer. Several local merchants were prosecuted after the big…

From: Al Balmer The Science/Math Forum · Geology January 23, 1995 7:15 PM
Doug, With the souped up laser, we could cut the specimen out of the mountain it came in, too. I suspect the power pack is getting a bit heavy at this point. Al

>>don't see where the subtle difference makes or breaks a photograph or design I'm especially embarrassed about fonts. I'm told that each of the thousands has their use, and it's vitally important to use the right ones, but other than a few which strike me as particulary horrible, I usually…
#163900 Mineral database Message #164005
From: Al Balmer The Science/Math Forum · Geology January 21, 1995 5:09 PM
Lanny, I think (and from other feedback here) that most monitors would be close enough. Most people (like me) are not really trained to see differences the way a publisher or graphic artist would. I've heard people complain about horrible gross mismatches that I couldn't even see. Unneccessary precision is…
#163904 Mineral database Message #164004
From: Al Balmer The Science/Math Forum · Geology January 21, 1995 5:09 PM
Lanny, Foxpro's a good package. I think the text form would certainly be good enough for the first version. Once you test the market, you have a better idea of how much resources you want to invest. Al

Doug, >> wonder if somehow it could decide luster also from that scan… Hmmm… There should be enough information there, but you'd have to get so close to the hardware it would probably be different for every brand. A scanner has a lot of stuff not needed, too. I wonder…

>> This is a complicated subject! I can believe that!. Do you have any feel for whether the typical monitor (VGA, 1MB video RAM) is "good enough" for the rather fuzzy matching we're talking about here? Al
#163468 #Mineral database Message #163577
From: Al Balmer The Science/Math Forum · Geology January 18, 1995 10:28 PM
Lanny, I think most modern computers are fairly good, but even though I'm a computer consultant, this isn't my area of expertise. I used to design logic circuits for Bausch & Lomb – that's where the color-blindness experts are. Maybe we could ask for help from the engineering section? >>…

Lanny, Xbase refers to the Dbase, Rbase, etc bunch of database programs. They are by different publishers but use the same data structures, hence have been lumped into the "X"base category, at least colloquially. >> exporting it as ASCII with a return separating records and a tab >> separating fields…

Hi, John, I thought there was a Pantone program to make monitor colors match the printed page, but I may be thinking of another product. Sort of a WYSIWYG for colors. Al

From: Al Balmer The Science/Math Forum · Geology January 16, 1995 5:27 PM
The nice part is the ability to colormatch on screen, with the program fitting the result into a range of possibilities in the DB. Within the limits of color reproduction on the average screen, of course. OTOH, even that can be calibrated, as I understand it (I think Pantone is…

May I make a suggestion? In the news flash items, you have several times recommended reading a particular message number. Could you also indicate what section it's posted to? Many people use off-line readers, and don't read or even quickscan every section. Thanks, Al
#158970 Carving Stones in KY? Message #159078

#156392 opal-yield from rough Message #156722
From: Al Balmer The Science/Math Forum · Geology December 2, 1994 7:16 PM
Russ, I think polarized light is used in industry for stress analysis of light-transmitting materials. I've been meaning to build an instrument for polarization testing anyway. I think the idea is roughly to put the sample between 2 polarizers, adjust for minimum transmission, and the stresses show up. Maybe someone…

David, One book I have lists occurrances in Italy, Finland, USSR, Greenland, Canada (on the Labrador Peninsula), California, and South Dakota. I also know that it has been reported in upstate NY. It's usefulness as a gem will depend on many factors, mostly play of color. It's not a highly…
