What.is.the.World.Made.of?
What is the world made of?
There are some great questions
that have intrigued
and haunted us
since the dawn of humanity.
What is out there?
How did we get here?
What is the world made of?
The story of our search
to answer those questions
is the story of science.
Of all human endeavours,
science has had the greatest impact
on our lives - on how we see
the world, on how we see ourselves.
Its ideas, its achievements,
its results are all around us.
So how did we arrive at
the modern world?
Well, that is more surprising
and more human than you might think.
The history of science is often told
as a series of eureka moments,
the ultimate triumph
of the rational mind.
But the truth is that power
and passion,
rivalry and sheer blind chance have
played equally significant parts.
In this series,
Ill be offering a different view
of how science happens.
Its been shaped as much by whats
outside the laboratory as inside.
Whoa! Whoa!
This is the story
of how history made science
and science made history.
And how the ideas that were
generated changed our world.
It is a tale of power,
proof and passion.
This time, delving deep
to find order and beauty.
What is the world made of?
Appearances deceive.
Beneath the surface,
our world is stranger
than we can possibly imagine.
Standing here, it certainly feels as
if I am standing on a solid surface.
But this is an illusion,
however convincing.
Nothing is really solid.
And you and I? Well, we consist
almost entirely of empty space.
If you took the entire population
of the world, all six billion of us,
and removed that empty space,
then we could be squeezed into
a cube smaller than that.
And it gets stranger.
Mobile phones and other electronic
devices which we rely on.
Well, they rely on particles that,
by any normal definition,
simply dont exist.
These insights all come from
our attempts to find out
what the world is made of.
Over the millennia, our
understanding has moved ever deeper,
revealing new layers
that make up the material world.
