keep razors sharp

Dr. Lenny likes crystals, rocks and pyramids. The title is one of the many mythic uses for our favorite shape - on the back of every dollar bill printed. One of my favorite albums of the early 80s was Alan Parsons Pyramania. I developed a fondness for regular geometric structures while learning group theory and molecular chemistry applied to architecture of molecules. Transition Metal elements can be coached by their environment to take on square pyramidal geometry by creation of a ligand field that electronically prohibits the regularly preferred octahedral geometry. The square pyramid shape is most prevalent with biological Nickel.

Pyramids were central to a theory of youth concerning the excavation necessary to build the empty mirror image of the pyramid under ground, providing materials for the above ground form. Apparently, somebody has been doing real thinking about this problem again recently - enjoy
this article . And have a good Good Friday.
