Discover how the migration of peoples has shaped the modern world.This beautifully illustrated book details the movement of people and cultures around the world – from the early migrations of Homo erectus out of Africa 50,000 years ago to modern refugee movements and migrations.

Today, India’s space program has morphed into something larger. The country looks towards the stars―not to sustain itself, but to explore, to reach the final frontier, and to take its own place amo
