Deus Vult (“God Wills It”) is a Christian motto associated with the Crusades and was first reported in the Gesta Francorum (“The Deeds of the Franks”), a chronicle written in Latin of the First Crusade.

Big Business from Common Things

The more I learn about the world the more fascinating it gets, human creativity and ingenuity is boundless. Maybe Einstein was right when he said that the true sign of intelligence is not knowledge but imagination. If you can imagine it, you can create it, you are limited only by your imagination.
