Newton,and others,should have realized that a static(静止的)universe would soon start to shrink under the influence of gravity. But suppose instead the universe is expanding.If it was expanding fairly slowly,the force of gravity would cause it eventually to stop expanding and to start shrinking...
As an undergraduate at Cambridge, Newton entered into his 'Waste Book' an assumption that we have named the Equivalence Assumption (The Younger): '' If a body move progressively in some crooked line [about a center of motion] ..., [then this] crooked line may bee conceived to consist ...

How is it related to Newton?Mass and Weight:Mass is an intrinsic property of matter which does not change and is not dependent on anything at all. It is what the matter made of. Where weight is the gravitational pull on the matter. Weight is dependent on the gravitational acceleration,...

1904. He came from a family of first- and second-generation German immigrants striving to be American. Ethnically and culturally Jewish, the Oppenheimers of New York belonged to no synagogue. Without rejecting their Jewishness they chose to shape their identity within a uniquely American offshoot ...
Gauss-Newton Methods for the Nonlinear Complementarity Problem. It is a result of Mangasarian that the nonlinear complementarity problem is equivalent to the solution of a system of nonlinear equations. This paper consi... Subramanian, P. K 被引量: 7发表: 1985年 One-step quadratic convergence of...
A five-point one-step block method based on the Newton backward divided difference formulae for the solution of first-order delay differential equations is derived. The proposed block method will approximate the solutions of initial value problems at five points simultaneously using variable step size...
This paper gives a solution to the scaled ℋ∞ optimization problem with constant scalings and output feedback. It is shown that, when the nominal plant transfer matrix has a special rank-one property, this optimization problem is equivalent to a sequence of convex optimization problems involving...
