The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid. To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one,...
Since the natural-origins theory has a number of issues, if they have a similar nodule that is known to be artificial, that would be pretty good evidence that mine are artificial too. I was pretty well convinced that they were artificial at this point. But this new confidence was even sho...
Table 2.The MAT_024 material model parameters determined for photopolymer base material “Grey Pro”. Before addressing the experimental response, it is important to note that the deformation rates employed in the computational simulations were significantly greater than those of the actual experiment (...
