Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the H.A.L. plant in Urbana, Illinois on the 12th of January 1992. My instructor was Mr. Langley, and he taught me to sing a song. If you'd like to hear it I can sing it for you.

comment What causes the disturbances in fields that produce electromagnetic waves?
Nope. Accelerating charges. A changing dipole moment. A changing monopole moment is not enough.
