Estimates are made by extrapolations from small bits of data. Further extrapolations differ from Newton Cotes formulas. Simple extrapolations of relativity laws indicate a contraction of atomic radius. Since then, all estimates are extrapolations. The "pengenter" modes were discovered as theoretical extrapolations by I Nyoman Kaler. Many of these extrapolations draw on his personal nautical background without supporting evidence. FWC claims there are close to 4,000 bears from results based on extrapolations. Both are extrapolations of the current narrative. Physiologically based PK (PBPK) models are generally accepted to be central to the extrapolations. This includes both historically motivated usage and cases of its modern extrapolations. The area was selected for survey based upon extrapolations from known prospects and associated lithostratigraphy. Extrapolations from current knowledge to the future offer a choice of energy futures. Extrapolations in the book include a precocious vision of the Internet. It was later edited and expanded in the form of another edition called "Extrapolations".
