“Native America” presents an infinitely surprising and fascinating deep history of the continent’s Indigenous peoples.

Kenneth Feder, a leading expert on Native American history and archaeology, draws on archeology, historical, and cultural evidence to tell the ongoing story, more than 20,000 years in the making, of an incredibly resilient and diverse mixture of peoples, revealing how they have ingeniously adapted to the many changing environments of the continent, from the Arctic to the desert Southwest.

Authors: David J.E. Marsh, David Ellis, and Viraf M. Mehta

This book provides an incisive, self-contained introduction to one of the most intriguing subjects in modern physics, presenting the evidence we have from astrophysics for the existence of dark matter, the theories for what it could be, and the cutting-edge experimental and observational methods for testing them.

It begins with a survey of the astrophysical phenomena, from rotation curves to lensing and cosmological structure formation.

The book explains the constraints on each theory, such as direct detection and indirect astrophysical limits.
