Armed Polite Society

I read in the Seattle media today that EV chargers in Seattle are being stripped for their copper.  People are using battery saws or angle grinders to slice through the cable.

Not just happening in Seattle.

Just another reminder that we can't have nice things, including environmentalism, if we don't have law and order. The coastal states will eventually have to come to grips with the reality that none of their utopian visions matter if they don't have a functioning society as a pre-requisite.

. . . IIRC Optical glass has a very high refractive index for lens purposes.  I vaguely recall that "optical" glass had lead in it and the lenses were advertised as containing lead.  I also recall that lead lenses were soft and easily scratched.   . . .

Depends on the type of optical glass. They put all kinds of stuff in there to tailor both the refractive index and the dispersion - at one time they even included thorium in some glass. (Yep. It was radioactive.) They also have to control the transparency as a function of wavelength. Often glasses with desirable optical characteristics have other problems - very soft, prone to staining, striae, etc. And of course cost.

Here's a sample glass map showing index and dispersion for various glasses from just ONE manufacturer.

Brain fart on my part and I changed it

And you'll need to change it again because it's probably over $60 million by now.
