The law of conservation of energy states that energy can neither be created nor destroyed; it can only change form. A common example is the apparent “loss” of energy when a ball is dropped from a ...

The PaStiX (Parallel Sparse matriX package) is a open-source scientific library that provides a high performance parallel solver for very large sparse linear systems based on direct methods. Numerical ...

Graph theory can be used to model and explain different phenomena from physics. In this paper, we show that one can interpret quantum experiments composed of linear optics and probabilistic sources ...

It's almost always the last topic in the first semester of introductory physics—angular momentum. Best for last, or something? I've used this concept to describe everything from fidget spinners to ...

When I get excited about a movie, my only way of calming down is to do a little physics. That explains why I found myself pondering Hooke's law and Young's modulus while watching a trailer for ...

Introduction Have you ever played with a Slinky, used a pinball machine, written with a click pen or ridden in a car? If so, then you have made use of a spring! Springs are in machines all around us ...

Plants are not able to move around and so they need to be able to adapt their growth and development to seasonal changes in their environment. For example, prolonged exposure to cold temperatures ...

Deep sequencing has enabled the investigation of a wide range of environmental microbial ecosystems, but the high memory requirements for de novo assembly of short-read shotgun sequencing data from ...
