ABC Radio National’s Big Ideas program: Reith Lecture Series – Scientific Citizens

Part One: Scientific Citizens. In the first of this year’s Reith Lectures, Lord Martin Rees explores the challenges facing science in the 21st century.

We are increasingly turning to government and the media to explain the risks we face. But in the wake of public confusion over issues like climate change, the swine ‘flu vaccine and, more recently, Iceland’s volcanic ash cloud, Martin Rees calls on scientists to come forward and play a greater role in helping us understand the science that affects us all.

…Today, science has transformed our lives. Our horizons have hugely expanded; no new continents remain to be discovered. Our Earth no longer offers an open frontier, but seems constricted and crowded – a ‘pale blue dot’ in the immense cosmos.

My theme in these lectures is that the Royal Society’s old values should endure. Today’s scientists, like their forbears, probe nature and nature’s laws by observation and experiment. But they should also engage broadly with society and with public affairs.

Indeed, their engagement is needed now more than ever. Science isn’t just for scientists. All should have a voice in ensuring that it’s applied optimally – and to the benefit of both the developing and developed world. We must confront widely-held anxieties that genetics, brain science and artificial intelligence may ‘run away’ too fast. As citizens, we all need a feel for how much confidence can be placed in science’s claims. And these are themes I’ll explore in all four lectures.

And, as I’ll discuss, this is a crucial century. The Earth has existed for 45 million centuries. But this is the first when one species, ours, can determine – for good or ill – the future of the entire biosphere…
