Gack! Ozone-hole-ism again already?

Ozone is the RESULT of UV being "blocked" by O2. A UV photon dissociates
an
O2 molecule into two O atoms, which grab onto the nearest molecule, like
O2, which PRODUCES O3.

O3 isn't what "blocks UV" - O3 is the result of the UV being blocked by
plain ol' ordinary everyday oxygen.


Rich,
Not really correct.
Ozone is formed from O2 by very short UV wavelengths less than 240 nm (as
well as electrical arcs). Once formed it can then absorb wavelengths up to
290nm or so

But the teaching of actual science, or practically any facts at all,
went out the window when the unions took over the schools and turned
them into propaganda mills that teach nothing but "Self-Esteem" -
"Duh, I dunno how to add two and two, but I feel real good about myself,
yup, yup, yup, yup!"

Thanks,
Rich

I agree, there are an awful lot of people here who have a lack of knowledge
and no shortage of self-esteem.
