Schrodinger Equation
In the Schrodinger equation, the wavefunction is wavelike wherever the particle's kinetic energy would be positive, and exponential-like (evanescent) wherever it would be negative. For wavefunctions of particles with zero rest mass (such as photons), this means that any evanescent portions of the wavefunction are associated with a local negative mass-energy.

Famous quotes containing the word equation:
“A nation fights well in proportion to the amount of men and materials it has. And the other equation is that the individual soldier in that army is a more effective soldier the poorer his standard of living has been in the past.”
—Norman Mailer (b. 1923)
