Greek Letter Omega (Ωμέγα - Ω)

Omega

"Big o". It was marked specially by a bar under the upper case, doubling the lower case. This letter was not introduced in the Latin alphabet, but survives as the symbol for electric resistance (ohms). The apocalypse has the Lord say, "I am Alpha and Omega, the beginning and the end." Tielhard de Chardin, the priest-archeologist and mystic who discovered Peking Man, saw evolution reaching the "omega point".
