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 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 ...
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 ...
[1] Einstein's scientific publications are listed below in four tables: journal articles, book chapters, books and authorized translations. Each publication is indexed in the first column by its number in the Schilpp bibliography (Albert Einstein: Philosopher–Scientist, pp. 694–730) and by its article number in Einstein's Collected Papers.
hnology (PhET) computer simulations relevant to concepts in Sciences and Mathematics. There is a notable gap in the literature of simul. tion-based technologies, learning theories, and Physics pedagogy in higher education. This action research study addresses that gap by exploring the role of the intentional inclusion of PhET.
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.
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.
