Witryna23 paź 2024 · The origin of the word crystal lies in the Greek word ‘Krustallos,’ which means ice as well as rock crystal. Interestingly, the ancient Greeks thought clear quartz crystals to be ice that doesn't melt.

Witryna10 lut 2024 · This is beautifully illustrated by the calcite plates (stereom) of echinoderms, which exhibit complex, sponge-like morphologies and curved surfaces and yet behave as single crystals. Extraordinarily, the stereom of certain species is highly ordered. A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
