The first dendritic patterns were discovered in palaeontology and are often mistaken for fossils because of their appearance. The first theory for the creation of these patterns was published by Nash and Glicksman in 1974, they used a very mathematical method and derived a non-linear integro-differential equation for a classical needle growth.
Moss agate was once believed to be petrified moss, until it was discovered the moss-like formations are actually composed of celadonite, hornblende, or a chlorite mineral. Plume agates are a type of moss agate, but the dendritic "plumes" form tree-like
Dendritic arborization, also known as dendritic branching, is a multi-step biological process by which neurons form new dendritic trees and branches to create new synapses. [1] Dendrites in many organisms assume different morphological patterns of branching.

Moss agate pebble, 1 inch (25 mm) long Montana moss agate. Moss agate is a semi-precious gemstone formed from silicon dioxide.It is a form of chalcedony which includes minerals of a green color embedded in the stone, forming filaments and other patterns suggestive of moss. [1]
It is a dendritic amalgam of crystallized silver, obtained from mercury in a solution of silver nitrate; so-called by the alchemists, among whom "Diana" stood for silver. [ 2 ] [ 3 ] The arborescence of this amalgam, which even included fruit-like forms on its branches, led pre-modern chemical philosophers to theorize the existence of life in ...
If you can read cursive, the National Archives would like a word. Or a few million. More than 200 years worth of U.S. documents need transcribing (or at least classifying) and the vast majority ...
Agate. Agate is a fibrous, banded variety of chalcedony that occurs in a variety of colors and patterns. [9] Iris agate shows exceptional iridescence when light (especially pinpointed light) is shone through the stone. Landscape agate is chalcedony with a number of different mineral impurities making the stone resemble landscapes. [10]
