Introduction

"Albert Einstein is undoubtedly one of the most fascinating and influential figures of the modern era. As a preeminent physicist, he radically transformed our understanding of the universe. As an ardent humanist, he took an active and outspoken stance on the significant political and social issues of his time. As a committed Jew, he advocated a distinctive moral role for the Jewish people. Albert Einstein's contribution to modern physics is simply unique. His scientific career was a constant quest for the universal and immutable laws, which govern the physical world. His theories spanned the fundamental questions of nature, from the very large to the very small, from the cosmos to sub-atomic particles. He overturned the established concepts of time and space, energy and matter. Einstein played a crucial role in establishing the two pillars of 20th century physics: he was the father of the theory of relativity and a major contributor to quantum theory."
