it. For instance, look at the book you are reading, your hands with
which you are holding it, and then lift your head and look around

duced by the greatest television producer in the world cannot pro-
vide such a sharp image for you. This is a three-dimensional, col-
ored, and extremely sharp image. For more than 100 years, thou-
sands of engineers have been trying to achieve this sharpness.
Factories, huge premises were established, much research has been
done, plans and designs have been made for this purpose. Again,
look at a TV screen and the book you hold in your hands. You will
see that there is a big difference in sharpness and distinction.
Moreover, the TV screen shows you a two-dimensional image,
whereas with your eyes, you watch a three-dimensional perspective
with depth.
For many years, tens of thousands of engineers have tried to

much more complex, much more successful and possess far superior de-
signs to these products of high technology.
