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:
“Jail sentences have many functions, but one is surely to send a message about what our society abhors and what it values. This week, the equation was twofold: female infidelity twice as bad as male abuse, the life of a woman half as valuable as that of a man. The killing of the woman taken in adultery has a long history and survives today in many cultures. One of those is our own.”
—Anna Quindlen (b. 1952)
