Dickite
Dickite, Al2Si2O5(OH)4, is a (kaolin) clay-like mineral which exhibits mica-like layers with silicate sheets of 6-membered rings bonded to aluminium oxide/hydroxide layers. Dickite is used in ceramics, as paint filler, rubber, plastics and glossy paper. It got its name from the geologist that discovered it around the 1890s, Dr. W. Thomas Dick, of Lanarkshire, Scotland.
Moronic Acid

But why it's called moronic acid is still unknown... Derivatives of this are called moronates, as in 'which moron-ate the contents of this jar?'
