EinsteinPy - Making Einstein possible in Python
===============================================

**EinsteinPy** is an open source pure Python package dedicated to problems arising
in General Relativity and gravitational physics, such as geodesics plotting for
Schwarzschild, Kerr and Kerr Newman space-time model, calculation of Schwarzschild
radius, calculation of Event Horizon and Ergosphere for Kerr space-time. Symbolic
Manipulations of various tensors like Metric, Riemann, Ricci and Christoffel Symbols
is also possible using the library. EinsteinPy also features Hypersurface Embedding of
Schwarzschild space-time, which will soon lead to modelling of Gravitational Lensing!
It is released under the MIT license.

Key features of EinsteinPy are:
* Geometry analysis and trajectory calculation in vacuum solutions of Einstein's field equations
* Schwarzschild space-time
* Kerr space-time
* Kerr-Newman space-time
* Various utilities related to above geometry models
* Schwarzschild Radius
* Event horizon and ergosphere for Kerr black hole
* Maxwell Tensor and electromagnetic potential in Kerr-Newman space-time
* And much more!
* Symbolic Calculation of various quantities
* Christoffel Symbols
* Riemann Curvature Tensor
* Ricci Tensor
* Index uppering and lowering!
* Simplification of symbolic expressions
* Geodesic Plotting
* Static Plotting using Matplotlib
* Interactive 2D plotting
* Environment aware plotting!
* Coordinate conversion with unit handling
* Spherical/Cartesian Coordinates
* Boyer-Lindquist/Cartesian Coordinates
* Hypersurface Embedding of Schwarzschild Space-Time
* Shadow cast by an thin emission disk around a Schwarzschild Black Hole
And more to come!
Einsteinpy is developed by an open community. Release
announcements and general discussion take place on our `mailing list`_
and `chat`_.

The `source code`_, `issue tracker`_ and `wiki`_ are hosted on GitHub, and all
contributions and feedback are more than welcome. You can test EinsteinPy in your
browser using binder, a cloud Jupyter notebook server:

.. _`wiki`: https://github.com/einsteinpy/einsteinpy/wiki/
EinsteinPy works on recent versions of Python and is released under
the MIT license, hence allowing commercial use of the library.
