Hi, I'm Vint Cerf.
I'm Google's Chief Internet Evangelist.
And I've been asked to select a few
of the many millions of videos in YouTube
that I've found the most profound and moving.
I've picked six of them in particular
to share with you.
The first one is by Pattie Maes from MIT
and she talks about what it's like
when a computer with a video camera
and a projector and microphones
and a headset or speakers,
embed itself into the same universe
that you and I interact with every day.
Here we see the power of having a computer
become part of our environment,
watching us make gestures and interpreting them
and literally becoming a partner
in the exploration of information.
The second video is from the Hubble Deep Field.
Here it was titled;
"The Most Important Image Ever Taken."
The Hubble space telescope zooms outward
some 14 or 141/2 billion light years into the past
to show the beginnings of galaxy formations
in our universe.
It's simply profound to recognize
how early in the evolution of the universe
galactic structures were forming.
It simply gives us a sense of
how tiny and small we are
in this vast universe that continues to evolve.
The third video is called
" Big Dog from Boston Dynamics".
This was a Defense Advanced Research Projects
Agency (DARPA) effort to build a robot
which is capable of carrying very heavy weights,
more than the robot itself weighs.
It really does have a very animal
like appearance to it.
It's even a little bit unnerving
because the thing is very stable on its feet,
you can push it very hard and it adjusts
its posture to recover from that
and it can carry heavy loads over
very, very rough and varied terrain.
I've found this fairly stunning to think that
we've gotten this far into the production
of robotics for practical applications.
The fourth video is by Brian Greene
and it's called "The Elegant Universe;
Einstein's Relativity".
And here we get one of Brian Greene's
beautiful, clear and very exciting explanations
for what it was that Einstein recognized
when he was able to see the Universe
as a four dimensional manifold,
in which topology played such a critical role;
curvature emulating gravity
in this four dimensional space.
Of course later,
Brian goes on to explain string theory in other
videos which I recommend that you find.
Here we see extraordinary 11 dimensional
universes being considered
a much more complex topological structure,
the Calabi-Yau spaces for example.
Illustrating things in the small;
quantum gravity for example,
in addition to the things in the large
which Einstein so ably described.
The fifth video is by Richard Feynman
who is an extremely noted physicist;
many years at Caltech, he worked on
the Manhattan Project and the Atomic Bomb,
he had a remarkably bizarre
and quirky sense of humor,
very googley I think.
But here you see the wonderful clarity
and enthusiasm of Feynman's lectures.
This one was called
"The Inconceivable Nature of Nature."
And you have this feeling of young boyish
awe that Feynman exhibits
and this determination to understand exactly
how this universe of ours actually works.
And finally we hear from Stephen Hawking,
in another one of the TED videos.
Hawking of course as you all know,
occupies the Newton's chair
at Cambridge University,
but more importantly this man,
who otherwise is physically disabled has shown
such remarkable ability in physics,
he speaks profoundly of the universe around us,
and also maintains this remarkable sense of humor.
You have to catch his commentary on aliens
and what they're likely to,
what we're likely to encounter
if we meet them or they meet us.
So those are the six videos that I found
the most interesting in a quick look
at what's out there on YouTube.
I'm sure you'll find many more.
It's been a lot of fun.
Thanks so much for letting me
take time to chat with you.
Bye for now.
