The newton-second (also newton second; symbol: N⋅s or N s) [1] is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second ( kg⋅m/s ). One newton-second corresponds to a one- newton force applied for one second. It can be used to identify the resultant ...
Zeitschrift für Mathematik und Physik, 62, 225–244, 245–261. General relativity. [74] A breakthrough paper, written in collaboration with Marcel Grossmann, in which the single Newtonian scalar gravitational field is replaced by ten fields, which are the components of a symmetric, four-dimensional metric tensor.
In mathematics, the Navier–Stokes equations are a system of nonlinear partial differential equations for abstract vector fields of any size. In physics and engineering, they are a system of equations that model the motion of liquids or non-rarefied gases (in which the mean free path is short enough so that it can be thought of as a continuum mean instead of a collection of particles) using ...
The third of James Clerk Maxwell's papers concerned with electromagnetism. The concept of displacement current was introduced, so that it became possible to derive equations of electromagnetic wave. It was the first paper in which Maxwell's equations appeared. Hall, E.H. (1879). "On a New Action of the Magnet on Electric Currents".
Schön's topic of research was condensed matter physics and nanotechnology. He received his PhD from the University of Konstanz in 1997. During late 1997, he was hired by Bell Labs , where he worked on electronics in which conventional semiconducting elements (such as silicon ) were replaced by crystalline organic (meaning carbon -based) materials.
The Navier–Stokes equations (/ n æ v ˈ j eɪ s t oʊ k s / nav-YAY STOHKS) are partial differential equations which describe the motion of viscous fluid substances. They were named after French engineer and physicist Claude-Louis Navier and the Irish physicist and mathematician George Gabriel Stokes. They were developed over several decades ...
The concepts invoked in Newton's laws of motion — mass, velocity, momentum, force — have predecessors in earlier work, and the content of Newtonian physics was further developed after Newton's time. Newton combined knowledge of celestial motions with the study of events on Earth and showed that one theory of mechanics could encompass both.
The B2FH paper [1] was a landmark scientific paper on the origin of the chemical elements. The paper's title is Synthesis of the Elements in Stars, but it became known as B 2 FH from the initials of its authors: Margaret Burbidge, Geoffrey Burbidge, William A. Fowler, and Fred Hoyle. It was written from 1955 to 1956 at the University of ...
