Phil, have you heard about the people that have been pointing 
green lasers at airliners and cop choppers? Seems like they get 
caught almost all the time.  I mean a laser as you know is a 
pinpoint of light, all you need is a GPS position and you 
probably will catch the perp if he or she is not mobile.  Jim

Subject: Speaking of Laser Beams

I was rooting around in the online NLS library the other day for 
something
new to read.  I have about a dozen books on my phone I am 
interested in
reading and about two dozen in my wish list waiting to be 
downloaded to my
iPhone when I am ready.  I stumbled on a book called What is a 
Laser.  It
was, and is, just 37 minutes long and was recorded back in 1983 
but if you
want a grade school level of how lasers work, it is a great read.  
Besides,
grade school is about my level at my advanced age.  Even then, I 
didn't
understand everything.  And to think they could measure the space 
between
atoms back then and a laser, even back then, could drill a 
perfect hole in a
human hair.  If you still have hair, that is.  In my case, they'd 
have to
use my Abraham Lincoln beard.  Right up front, this little book 
said, if you
turned on all the light bulbs in the world at the same time, it 
still
wouldn't equal the output of the earliest of lasers.  Don't burn 
yourself.
Now if the laser could just grow hair.

Phil.
