Origins of Structure,The problem of galaxy formation is one of the most complex in all of astrophysics. With a hundred billion galaxies in the observed portions of the Universe, they are certainly no accident. Yet we do not know how they got there.

To formulate the theory, he had to invent mathematical techniques that described the observations and showed their interrelationship. His struggles with the mathematical problems are recorded in his book .

In this quest we hope to clarify the origin of the chemical elements, identify processes that led to the formation of galaxies and stars, and come to an understanding of the factors that played a role in the formation of the Earth and planets. To this end, we start with an investigation of what
