We want to know as much as possible about the world around us,

but to satisfy our need to know about the world

around us, our eyes just aren’t good enough anymore.

With the power of engineering, we have been able to take a look at worlds

hidden inside and outside the narrow range of our human senses.

We can take a look at the smallest lifeforms, our own cells, and even

molecules using electron microscopes.

Complex machines that make invisible things visible,

so we can discover worlds inside of worlds inside of worlds inside of worlds.

Discoveries of the nanolevel have changed how we perceive

the universe around us forever, and led to countless discoveries.

On the other hand, just a few centuries ago engineers developed powerful

tools of science that gave us the ability to look deep into space

and spot countless wonders of the universe.

Later came spacecraft and satellites.

The Hubble telescope was one of these wonders of technology.

Without it, we would never have known that our galaxy is one of billions in

an enormous universe, and even better telescopes are being built right now.

They’ll be able to show us worlds far, far away in much greater detail.

So, there is still much left to discover.

The universe is vast, and we have so much more to learn.

And with the power of engineering and our curiosity, who knows what

we’ll be able to discover in the future.
