Re: [Phys-l] The "why" questions

Thanks.  I was going to mention K-K and causality a few days ago   Long before Wikip.  I lit. searched extensively (ca. 1969) causality WRT the K-K relations for my disst. [I used them to check the internal consistency of my measurement of the complex index of metals.]

bc barely understood it then;  definitely not now.
