Carl Sagan wrote Cosmos to place human history inside the far longer history of the universe, and the book has stayed in print because that framing still works.
It moves between astronomy, physics, biology and the history of science, following how people came to understand the scale of space and time and what that understanding asks of us. Sagan's prose is plain and unhurried, aimed at readers with no technical background, and the case for scientific thinking runs through every chapter. Published by Little Brown.
Chief attractions:
• The origins and structure of the universe explained without jargon
• History of scientific discovery woven through the science itself
• Reflection on humanity's place in cosmic scale and time
• A landmark of popular science writing that is still widely read
For readers drawn to astronomy, the history of ideas and science writing at its clearest, published by Little Brown and available from Boipoka.
