[This is the actual format which our Computing Center uses for change
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.
