Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

Our purpose in this paper is to study the convergence rate of some variants of the Schwarz alternating method for solving two types of singularly perturbed advection-diffusion equations, one in which ...

Abstract: Tokamaks are important devices in fusion technology in which high intensity magnetic fields are used to confine hot plasama. The paper reviews some numerical methods for the solution of Grad ...

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...

Abstract: A complex-frequency-shifted perfectly matched layer (CFS-PML) for the face-centered cubic finite-difference time-domain (FCC-FDTD) method with second-order in time and fourth-order in space, ...

Column subtraction is a way of subtracting larger numbers. It is called column subtraction, because you write one number underneath the other, using place value to sort the tens and ones in separate ...
