How did the great scientists make their remarkable discoveries? And what kind of men were they? This companion volume to Great Inventors and their Inventions introduces the work of nine men to younger readers, and ranges from the world of Ancient Greece to the 20th century discovery of DNA. Included are the crucial discovery that the earth goes round the sun (Galileo), the principle of gravity (Newton), the evolution of the species (Darwin) and the principle of inherited characteristics or genetics (Mendel).
