The following is a notice that appeared on one of the Usenet newsgroups August, 1993.
[This is the actual format which our Computing Center uses for change notices.]

Effective: September 15, 1993

Product: Planck's constant 'h'

Version: 1.1 (Replaces 1.0)

Systems: The universe as we know it

Change: Upgrade to '2'.

Image: Every atom and photon in the observable universe

Installer: God the Father, Son, and Holy Spirit

Contact: Richard P. Feynman

Notes: The referenced change to this physical constant will end all life as we know it on this planet and in the observable universe. From the equation E=hf which denotes the energy of a photon as the function of its frequency, we see that photons will suddenly carry much much more energy. The emissions from your TV remote will become as dangerous as gamma rays; you would shoot holes in the wall with it, except that the Uncertainty Principle says you won't be able to pick up the remote because you won't be able to determine its position (nor the position of your hand) to enough precision to tell you if it's even in the same room with you.

Users inconvenienced by this change should call the Help Desk in 216 Computing center(645-3540) or the Graphics Consultant in 204 Computing Center.
