Transcript: Electronics at the cutting edge

TIM DRYSDALE
Electronics has come a long way in seven decades. Even more importantly, it’s helped the world develop at a pace that is unprecedented in human history.
BERNIE CLARK
Ray Kurzweil estimates the next 100 years will bring a rate of change equal in impact to the last 20 000 years.
PHIL PICTON
Electronics is behind this rapid pace of change. It powers computers that allow us to design, communicate and investigate.
ARMANDO MARINO
The internet can connect us to friends and relatives anywhere on the planet.
JEFF JOHNSON
Computer-aided design processes have advanced many fields of engineering.
TIM DRYSDALE
Medical technology has benefited from 3D imaging techniques that see safely inside the body using light, sound and magnetic fields.
BERNIE CLARK
Electronic equipment is vital to the satellites that allow us to explore the deepest reaches of space.
ARMANDO MARINO
It is essential to keeping humans alive and well in the International Space Station for long periods of time.
TIM DRYSDALE
Our understanding of the world has moved on dramatically through scientific endeavours.
PHIL PICTON
Large-scale investigations of the so-called God particle at the Large Hadron Collider are only possible with the aid of electronics to control the equipment.
BERNIE CLARK
From the smallest GPS trackers used by polar explorers to the largest of facilities on the planet …
JEFF JOHNSON
… the smart vehicles that criss-cross the surface of the Earth, running on autopilot …
ARMANDO MARINO
… to the vessels that explore the deepest reaches of space …
PHIL PICTON
… electronics is everywhere, and underpins the unprecedented rate of technological change.
TIM DRYSDALE
We learn electronics to gain insight into the technologies that touch at the heart of almost every human endeavour.
