Digital Technology 

We live in a digital world! Bits, bytes, jpegs, mpegs, USBs, CDs, DVDs, HDTVs! Digital technology is everywhere. What was once considered science fiction is now science fact. Ever wondered how your mobile phone works? Or how an MP3 player holds so much data? Or how a digital camera captures an image?

Over the last twenty years digital technology has completely revolutionised the way we see, hear, talk, play and communicate with each other. Just about every electronic gadget we use is the result of digital technology. Gadgets have become so much a part of our everyday lives that it's difficult to remember what we did before we had them!

In this episode Dr Rob zips through time from the past to the present, to the future and beyond! You'll even get a "behind the scenes" sneak peak at how digital technology made SCOPE possible! Tune in to discover how Dr Rob once again, makes the ordinary - extraordinary "under the SCOPE!"
