"..........if all goes well we will allow humanity to benefit step by step from our Scientific Advances.   Depending upon the uses that will be made of it, we will see if we can give humanity all our knowledge and allow you to enter the intergalactic era with our 25,000 years of Scientific Progress as your inheritance....... "---- from the section titled "Overpopulation" Chapter 7 in "Le Livre Qui Dit La Verite" as transcribed by RAEL in December 1973
Before, I introduce ACWED I feel that it's appropriate that I
introduce the Science of Optics and Photonics because ACWED is only one
application of a myriad of applications of this Science. I introduce
the branch of Science with a video of a Scientist speaking.
This Scientist is Dr Robert Lieberman :
a Past President of the  
SPIE   (the society for light based technologies).
This video was published on YouTube on 6th October 2015. At this time
this Scientist was "President-Elect" of the SPIE.
The duration of the video is 10 minutes During a brief section of
this video, this Scientist introduces Optics and Photonics and talks
about the impact of light based technologies on the world today
