Physics is Phun

Dr Dog anyone?  >
Anyway today has been another slow day, but still good. I did go over the start up process for the laser system, making a useful procedure document for anyone besides Aurelion who would like to turn the laser on, which is important because he'll be gone in a few weeks.

One of things I've noticed while working in the lab is the use of these ruby-red laser shields, which remind me an awful lot of Cyclops's glasses from the X-Men.

One of the remarkable things about the shields is that you cannot see the green laser at all. So it got me thinking about the physics of Marvel's superhero. To all the true believers out there, it will come as no surprise that the simple glass of his visor should actually be able to block his destructive lasers, given that they block whatever wavelength his eyes operate on. However, since his optic blasts are clearly red, his visor should not be red too since that would allow the light to pass through. Think filters on stage lights, white light hits the red filter, the red filter blocks all other wavelength and allows red to pass through. In short, we're all living a lie. 

I forgot a quote on my last post, so here's two. 

"Watch it, bub."
-Wolverine

"Life is to be lived, not controlled, and humanity is won by continuing to play in the face of certain defeat."
-Ralph Ellison
