Suggestions for responsibly managing your kids' use of technology.

One day in the not-too-distant future it may be possible to produce an image of what someone looks like based only on their DNA. In the meantime, forensic police have many high tech tools at their disposal to help solve crime.

Dr Tony Heyes takes us through the big theories of science and how scientists have responded to philosophy. He shows how the more a scientific theory claims, the better the theory because it can potentially be disproved more easily. At the end of the day, nothing is absolutely certain. Science is tentative, provisional and only a metaphor of reality.

Retired satellite telecoms expert Graeme Hanigan's pet project is the preservation of the first ever commercial solar power station, built in 1980, at White Cliffs in western New South Wales. Graeme explains how it worked and why it should be recognised as an important part of Australia's engineering heritage.
