Epilogue: A Vector Vision
Albert Einstein once said, “The theory must be as simple as possible. But not more simple!” He was talking about the fundamental laws of physics, but we can apply this advice to our business. The art of geophysics lies in finding the appropriate approximations to describe the complexities of the real world in useful ways, ways which will help us understand our data. We do this through a long series of approximate models, each of which progressively violates what we know to be a more fundamental reality.

Understanding Seismic Anisotropy in Exploration and Exploitation
The subject of seismic anisotropy has a long history, but only recently has it come to be seen as a central feature of geophysics, as applied to the exploration for hydrocarbons and to their exploitation. The reason for the long neglect of anisotropy is, of course, that isotropy is simpler. The equations are simpler, and the application of one's intuition is more direct. And, perhaps because of their simplicity, these basic, isotropic ideas have enabled the discovery most of the world's known hydrocarbons.
