Most Influential Scientists Who Changed the World [PDF ebook] 

There are a handful of famous mathematicians, scientists, investigators, and researchers who have shaped and influenced the world, and brought about significant changes in our lives. This book reviews these influential people, their lives, discoveries and inventions, and their impact. For many of them, their lives are equally as important as their insights, theories, and inventions. This book pays homage to what they have suffered and endured to provide for generations to follow them. Each one of these individuals has left their mark on the world, influenced their discipline, and deserve recognition. This book intends to honor them, and at the same time, educate the current generation that may not recognize their names or contributions to their field and to the world.
