Where did the Step function Q come from?
- Viscosity (not rate independent)
- Metastability
- Falling off cliff independent of rate of approach

- Large gradients, short lengths
- Continuum theory violated
- Information loss in singular “black hole”
Dislocation junction metastable:
jump to contact, jump when broken
