This is our opening slide
for all of the lectures.

So what does it mean?

It's called Incheon Bridge,

and it's located
in South Korea, near Seoul.

This bridge was finished in 2009,

and now it connects
the airport serving Seoul

to what's called Songdo Business District,

which was built on reclaimed land.

The private contract owner 
behind the bridge was Samsung.

One reason we chose this particular image

is simply that South Korea
has itself been successful

in terms of economic development.

When it comes to development,
Alex and I are very much optimists.

But look more carefully at this picture,

which was taken before
the bridge was finished.

You can see the bridge is incomplete.

We view economic development
as something which is always in process.

Most importantly, this image reflects
an underlying philosophy of education,

namely that we should always be trying
to bridge gaps in our knowledge.
