2. IMPORTANT DISCOVERIES
 The fire was vital for human development
as our ancestors provided light and
heat, were given the opportunity to cook
their food and shelter from predators that
threatened.

3.  Without electricity we would still be in the
dark. Modern society and their lifestyles are
based absolutely on this important
discovery, made by Benjamin Franklin. We
can not imagine a world without
computers, televisions, radios, microwaves, e
tc. All scientific advances after electricity was
discovered it needed to occur.

4. The Scotsman John L. Baird invented the
black and white television and was the
engineer who introduced Guillermo
Gonzalez Camarena in Mexico to 1927
television color.

5.  Computers are one of the most important
tools of modernity. Everything we do
today or what we access, as you are
reading this article, is via automated
systems. Imagine if suddenly halt all
existing computers: would stop
banking, commerce, education, medical
services, finally, collapse all daily activities
worldwide.

6.  There is no doubt that the Internet has
revolutionized the way we
learn, communicate and entertain. Today, the
family is no longer around to television, but
each is in its own computer and
communicate using it even if they are a few
feet away.
