A joyful celebration of science and civilization, but also a powerful polemic. Sagan views our existence from the perspective of an astronomer, and implores us to behave as a unified global civilisation on a small planet which must take responsibility for its own survival.
The First Three Minutes
Still the best book explaining what happened just after the Big Bang. Weinberg has a no nonsense, almost dead-pan style and his writing is lucid. Not surprising since he is one of the greatest physicists of the 20th century.
The Age of Wonder
A beautiful description of why we do science - Davy, Banks, Darwin - they were all correct: science is a romantic pursuit, and the more cynical 21st century view of science as some sort of vehicle for economic progress is plain wrong!
