Btw, I don't do quantum whatever the hells and such, but to me the reason why a 0-45-90 would work, or show light through it is that:

Light shines in 1000000 different ways, a polarizer allows light from 1 direction, the next one "filters" the light in a new direction, and same with the 3rd.
That's my rational behind still having light. Don't know if that makes sense behind my logic, or if my logic is BULL. But yeahhhh...

Just got a message from a physics guy He says this book is wrong,.,common sense prevails! But I wish it had been the mystery the book said it was....
