- Lest I get more hate mail from engineers, let me state for the record
- that I did not intend to make a disparaging statement about Dale, or
- engineers in general.
-
- I only meant to say that although it might seem silly to someone who's
- daily work is in classical physics, mathematical consistency is a very
- valuable guide for searching out physically correct models in particle
- physics. It is not logically necessary for this to be the case, but
- I know from long experience that it is so.
