Scientists created the entire architechture of the 20th century: radio, television, X-rays, Radar, MRI; all of that sprung forth from the mind of a scientist. When people come up to me and say: “You’re a physicist. But what have you guys done for me lately?”, my answer is: “EVERYTHING!” (Michio Kaku)

A few weeks before the US presidential election in 2008, BBC horizon produced a 50 minutes documentary entitled “The Presidents’ Guide to Science”. BBC argues that science and technology in large part provide the immense power to “the world’s most powerful man” (war, health care, energy, …) while most US presidents – like most heads of government around the world – have no background in science. That’s why the BBC asked some of the big names in science to share some words of advice. It couldn’t be verified whether the US president watched it or not. But what the scientists have to say is smart, fascinating and interesting for all of us, not only for presidents.
