50th anniversary of the equation that launched the search for ET.
Kevin Fong celebrates the anniversary of one of the most iconic equations ever written. The Drake Equation was created by Frank Drake some half a century ago in a bid to answer one of the most profound questions facing science and humanity: are we alone? Its creation launched a 50 year, genuine scientific endeavour to search for ET, known as SETI: The Search for Extra Terrestrial Intelligence. Kevin visits the SETI Institute in Northern California, to meet the great man himself, Frank Drake, and some of his scientific colleagues who have spent most of their working lives hunting for signs of alien life, out there in the cosmic ether.
