Finding Flash Rocks
Dean Campbell | Sat, 08/13/2022 - 10:20
Flash rocks were discussed in a previous post as stones made of quartz that produce light by triboluminescence when struck together. This post provides some description of their origins and tips on how to find them, making connections to some of their properties.
Paper Snowflakes to Model Flat Symmetrical Molecules
Dean Campbell | Wed, 04/06/2022 - 13:39
Flat, symmetrical molecules can be modeled by folding a sheet of paper, cutting patterns into the folded structure, and unfolding to produce the flat paper models. The finished models resemble paper snowflakes, but have a variety of rotational symmetries. Template patterns for several molecules are available for download in the Supporting Information.
Simple formation of metal mirrors
