I have covered several different software packages for doing scientific computation in Linux Journal, but I haven't spent as much time describing available libraries and the kind of work that can be ...

At its heart, general relativity is a geometric theory of gravitation in which spacetime is modelled as a four-dimensional Lorentzian manifold equipped with a metric tensor whose curvature encodes the ...

Scalar-tensor theories generalise Einstein’s general relativity by introducing one or more scalar fields that couple nonminimally to the metric. These scalar degrees of freedom can mediate long-range ...

Alena Tensor completely reverses this approach. It is much easier now to describe gravity in flat space-time in a way that mathematically reproduces general relativity and then uses the known tools of ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...
