This Blog is about Bone, an Invention Many Millions of Years in the Making, Conceived and Placed in Practice by the Cooperative Efforts and Patient Experimental Work of the Following Ai-Nanobots: Calcium, Phosphorous, Oxygen, and Hydrogen. And Let us not Forget the Tireless Efforts of Their Most Fantastic Invention, Their Co-Workers, the Boneless and Even More Ancient Carbon-Based Life-Forms.

Apatite, Ca5(PO4)3OH, has nothing to do with appetite or the desire to eat. Apatite was named by a German geologist in 1786 to reflect the minerals tendency to be deceptive by looking like something else. Apatein is a word that comes from the Greek and means misleading. At any rate hydroxyapatite makes up to 70 % of the content of human bones.

The OH of Hydroxyapetite or hydroxylapatite, as it’s more properly called, is easily substituted by fluorine, which adds hardness to apetite’s crystalline structure, a feature that accounts for the use of fluorine in decay- preventative toothpaste.  Carbonated calcium deficient apatite is found in tooth dentin.
