Science relies on imaginative breakthroughs made by visionary men and women working alone or in groups. Has the corporate collectivism of modern laboratory work begun to stifle the creativity and insight on which scientific discovery relies? Independent scientist James Lovelock, whose work led to a Nobel prize, makes a powerful case for the freedom of scientific speech.
Lovelock also discusses the origins of the Gaia theory with diplomat and environmentalist Crispin Tickell. From hypothesis to theory, he reviews the relevance of Gaia in the light of recent data on climate change and global warming.
