Richard Listers Hi when you have a chance click on this link on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280478300077&ssPageName=STRK:MEWAX:IT It looks like this could be one of Tims cm wood cubes (might I add I like the cm wood cubes he has done)? Well that is what I would assume that its a cm cube because that has been the set standard I have seen day in and day out with orientation cubes. Now for argument sake, lets say its a inch cube and the only reference I can go off of is only the image and the cube with the T on it. By default, I would assume its a cm size cube because that has been the set standard. But in actuality its the inch cube, or who knows, it could be 2.5 inch cube or 1.3 inch cube or a foot cube. Now this can cause some confusion when people use orientation cubes as a set standard for scale. When the scale changes in size the orientation cube has no use now when a new size is introduced or sizes. I like that he made the inch cube in celebration for Counts big find. I think it would have been more fitting and fun if he also branded the wooden cubes to say The Count Cube on every side to distinguish it from his cm wood cubes that he sells. What might happen is people might take the inch cube and use it as an orientation cube scale and this could cause confusion if you cant see the inch etched on one side in the cube because all of the other orientation cubes I have seen are cm, the standard that has been used. And also to take in consideration not all bidders on eBay are members on the Meteorite Central List. Shawn Alan
[meteorite-list] Scale Cubes [WAS: Ad Announcing the "Count" cube Scale / Orientation cube]Richard Kowalski damoclid at yahoo.com Mon Mar 15 04:32:25 EDT 2010 Previous message: [meteorite-list] Ad Announcing the "Count" cube Scale / Orientation cube Next message: [meteorite-list] Ad Announcing the "Count" cube Scale / Orientation cube Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Shawn, Matt, If I'm not mistaken, the scale cube was invented specifically for the lunar samples brought back by the Apollo missions. Obviously, the idea behind using a scale cube is just that, to show the scale of the object in the photograph. I agree that for good scientific reasons, a scale cube in some metric measurement makes the most sense. A cubic centimeter is most common, but why not a cubic decimeter or a cubic meter, if those are appropriately sized for the object? I have no problem with any sized scale cube as long as the dimension is clearly marked and visible in the photograph. 1-cm, 1 inch, no matter. There is no "standard" so to speak. The key is to use something of the appropriate scale for the object being photographed... I have no objection to using other objects too, again as long as they are easily identifiable. I might not know what the coin is, if one is being used for scale, but I immediately have a general idea how big is probably is. As long as I can unambiguously identify it in the photograph, that's all I need. If the image is poor and I can't determine exactly what coin it is, much less the country of origin, much of the value of using that coin for scale is lost. Most car keys are about the same size and have been for a very long time... Put them next to your rocks. I'll have some idea how big they are. Something that REALLY bothers me is something ambiguous, like dice. They all look the same and come in many different sizes. Even the standard ones have no markings that tell you they are standard size, or some other size. If you see them in a photograph, is it a standard die, a small one from a board game or is it a huge novelty die from a game show?? I can assume it is a standard die or close to it and get a general scale of the object. The same goes for the plastic 1-cm cubes you see in photos that have no scale marked on them. By the weight of the object you can guess the cube is 1-cm, but it's really a bad idea not to include the actual size of your scale on your scale object, no matter what size it is!
