Let's take a moment to think about your morning

and blast yourself with perfectly warm water in an attempt to wake up.

You smear your toothbrush with too much toothpaste

and scrub yourself into a foamy mess of minty freshness.

You're running late, so you skate downtown

weaving through the commuters, dart across the road

barely making the lights and jump on the train just before the doors beep shut.

There's a couple of stops to go so you pull out your

phone and play a few games of Angry Birds.

All these things were made possible by engineers.

But what prompts an engineer to improve our world?

and maths and science are the creative tools they use to solve them.

Problems like making your alarm go off at the right time,

or making sure your toothpaste is just the right balance of chemicals

Or even making a game so addictive it's almost impossible to put down,

Now let's head over to the airport and jump on an aeroplane.

Ahh aeroplanes, they're so easy to take for granted.

Before aeroplanes, flying was quite a bit more challenging.

Every bit of your plane has been touched by engineers.

A mechanical engineer designed the engine,

a mechatronics engineer devised the controls,

Electrical and software engineers created those.

It's the world's tallest building at 829.8 meters high.

It's also in one of the world's hottest environments,

One of the difficulties of building the Burj

was trying to figure out how to set forty-five thousand

cubic meters of reinforced concrete in such extreme weather.

A clever method of pumping iced liquid concrete

into the 55,000 tonnes steel frame during the night.

A building that's vertically over 800 meters high,

rather than horizontally all over the ground.

Now let's jump into our time machine and go back to Saturday,

The Sydney Harbour Bridge is about to open.

the bridge is a marvel of civil engineering,

and a pretty cool place to set off some fireworks.

Since 1815 people had been talking about building a bridge

The problem was that the harbour was so incredibly wide,

how could a bridge span such a width and support its own weight?

Well actually it was an idea they came up with.

The arched bridge works by transferring the weight into horizontal forces,

and bracing them at the ends of the arch.

Will we finally have affordable solar power?

Or robots that can perform life-saving surgery,

or a building that's so tall your view is of outer space.

Or how about finally engineering a working hover board?

And when they are, the idea is shared with the world to make all our lives better
