How accurate is Limber ’ s equation ?
Aims. The so-called Limber equation is widely used in the literature to relate the projected angular clustering of galaxies to the spatial clustering of galaxies in an approximate way. This note gives estimates of where the regime of applicability of Limber's equation stops. Methods. This paper revisits Limber's equation, summarises its underlying assumptions, and compares its predictions to th...
متن کاملHow accurate is molecular dynamics?
Born-Oppenheimer dynamics is shown to provide an accurate approximation of time-independent Schrödinger observables for a molecular system with an electron spectral gap, in the limit of large ratio of nuclei and electron masses, without assuming that the nuclei are localized to vanishing domains. The derivation, based on a Hamiltonian system interpretation of the Schrödinger equation and stabil...
متن کاملHow Accurate Is Peer Grading?
Previously we showed that weekly, written, timed, and peer-graded practice exams help increase student performance on written exams and decrease failure rates in an introductory biology course. Here we analyze the accuracy of peer grading, based on a comparison of student scores to those assigned by a professional grader. When students graded practice exams by themselves, they were significantl...
متن کاملHow Accurate is Gaussian Elimination?∗
J.H. Wilkinson put Gaussian elimination (GE) on a sound numerical footing in the 1960s when he showed that with partial pivoting the method is stable in the sense of yielding a small backward error. He also derived bounds proportional to the condition number κ(A) for the forward error ‖x − x̂‖, where x̂ is the computed solution to Ax = b. More recent work has furthered our understanding of GE, la...
متن کاملNoninvasive measurement of carboxyhemoglobin: how accurate is accurate enough?
Exposure to carbon monoxide (CO) is the leading cause of death by poisoning in industrialized countries. It accounts for hundreds of accidental deaths and thousands of intentional deaths annually in the United States. CO is a colorless, odorless gas that is easily absorbed through the lungs when inhaled. It competes with oxygen for binding to hemoglobin, but because hemoglobin has an affinity f...
