Why, you may ask, have I chosen the Phi symbol to represent Deism? It goes to one of the basic principles of Deism - God created the Universe. Before this amazing event there was nothing; afterward, there was everything.
The Greek letter Phi is described as a zero and a one combined - nothing and everything. Apropos to God's creation of the universe, I must say. Also, Phi is known as the Golden Ratio, the Divine Proportion, the Golden Mean, and the Golden Section. It is also described as a universal constant of design; the signature of God. Mathematically, Phi is written 1.618033...
To type the Phi symbol with your keyboard, hold the Alt key and on the numerical keypad type 1000. In HTML document creation you should use "& # 9 3 4 ;" (without quotes or spaces) and on web page fields (like the Google search field) hold the Alt key and on the numerical keyboard type 0934. Each of these should create Φ, if properly done, although it may display other unusual characters on some computers.
Most don't know the Greek letter Phi, nor what it means. Hopefully this will change very soon.
